A metro's plumbing is a portrait of its building history under its weather, and Des Moines's portrait is painted below from its own records: Census housing figures, NOAA climate normals, the metro's ZIP codes and communities. PlumbReach USA's role is the connection to a local professional; the portrait is here so that connection starts from understanding rather than urgency.

The median Des Moines home was built in 1984; 47.0% of the stock predates 1980, and the pattern this metro's own data ranks first is ageing cast iron sewer lines. PlumbReach USA is a referral service, not a plumbing company: one call connects you with an independent local plumber serving your ZIP code.
Des Moines is a metro of 720,331 people and 289,451 households, and its plumbing is a portrait of its building history. The median home here was built in 1984; 47.0% of homes predate 1980 and 27.1% predate 1960, while 33.0% have arrived since 2000. Every one of those eras plumbed differently — different pipe materials, different drain designs, different fixtures — and they fail differently, which is why this page is organised around the patterns the data actually produces in Des Moines rather than plumbing in the abstract.
The pre-1980 districts are not a museum; they are most of the metro's working housing, and their plumbing is a patchwork in the literal sense — original runs beside renewed sections, a heater of one decade feeding fixtures of another. Across 145,091 such homes in Dallas, Guthrie, Jasper, Madison, Polk, Warren, no two systems share exactly the same repair history, which is why the guidance below insists on pattern over incident: in patchwork plumbing, what has already been replaced is as diagnostic as what has failed.
The newer homes also house much of the metro's renting population, and rented plumbing lives a harder life: more occupants per system in many cases, faults reported later, and maintenance decided by someone who does not live with the drip. Across Des Moines, 289,451 households depend on systems most of them did not choose, and the post-2000 stock — 101,873 homes — is where the tenancy share runs highest. The failures are the modern ones: cartridges, heater elements, slab-line questions. They arrive on the subdivisions' shared schedule regardless of who holds the lease.
Over the housing sits one more dataset, the sky's: 6,178 heating degree days and 1,070 cooling degree days in the average year at DES MOINES INTL AP, IA US, an average temperature of 50.9 degrees, extremes at both ends faithfully recorded. A metro's plumbing is designed — to the extent it is designed at all — for the middle of that record, and it fails at the record's edges. What follows is a page about the edges: the cold snaps, the storm weeks, the long hot stretches, and the systems they find first.
Housing eras and climate, joined — the two datasets every section of this page is built from.
Lay the eras side by side instead: 27.1% pre-1960 (83,659 homes), 19.9% from 1960-1979 (61,432), 19.9% from 1980-1999 (61,432), and 33.0% since 2000 (101,873). No single era tells the story — the proportions among them do, and those proportions are different in every metro this site covers.
Growth is the headline in Des Moines: the post-2000 band is the largest, much of it slab-built subdivisions plumbed in plastic and fitted with cartridge fixtures. The work here is young-stock work — heater replacements arriving in waves as whole streets age together, slab-line questions, fixture internals — carried out on systems whose first owners often never needed a plumber. The metro's older pockets still generate the deep problems, but the volume of its plumbing future is being written in the new subdivisions.
Behind the leading era sits the founding stock: 83,659 homes from before 1960, 27.1% of the metro. Second place in the table does not mean second place in the workload — those homes carry the oldest drains and supplies in Des Moines, and a disproportionate share of its serious plumbing begins on their streets, in Des Moines's first districts and the suburbs that followed them.
Start the climate half where the water starts: underground. Des Moines's laterals rest in soil that takes 36.55 inches of rain in an average year and dries between deluges, swelling and shrinking against their joints through every season. Above ground the same record reads as workload — 1,070 cooling degree days of hot-water demand, 6,178 heating degree days of cold incoming water at DES MOINES INTL AP, IA US. A plumbing system here is never in neutral; the record keeps it working at one end or the other all year.
Hold the two halves together and the rest of this page explains itself: the problems ranked highest here are the ones where Des Moines's dominant housing era and its climate record overlap. Change either dataset and the ranking changes — which is precisely why this profile is rebuilt from the records for every metro instead of carried over from the last one.
Listed in the order this metro's housing and climate data supports.
The sewer line is the one pipe every fixture in the house shares, and the only one whose failure backs up into the home instead of draining away from it. Its enemies are time, roots and soil movement, working at the pace of decades. Service on the line begins with evidence — camera footage of its actual condition — because the difference between a cleaning, a sectional repair and a replacement is written inside the pipe, not in the symptom at the drain.
Put the metro's laterals end to end and they would run for thousands of miles — one private road per home, most of them laid generations ago and none of them inspected since. Des Moines's share of that buried network follows its building history: clay and iron under the founding districts, transitional materials in the post-war ring, plastic in the growth corridors around Ankeny. Sewer service here is the slow audit of that network, one camera run at a time, and its findings sort themselves by era so reliably that the footage often confirms the street's building date before it confirms anything else. That is the daily reality for the 289,451 households spread across Dallas, Guthrie, Jasper, Madison, Polk, Warren.
Sewer demand follows the founding map: the districts built first, around the old centre and out through Ankeny, hold the jointed clay and iron; the growth rings hold plastic with decades in hand. 27.1% of the metro's homes stand on the founding side of that line, which is why the footage here so often shows a pipe at the end of its story.
Pipes fail in two tenses: suddenly, at a joint or a split, and gradually, as a material narrows, thins or pits across a whole system. The first tense asks for a repair; the second eventually asks the larger question. Pipe services cover both — the sectional fix that restores a sound system, and the planned renewal that replaces a failing material through the whole house, routed to spare the building and staged to keep the household in water.
Every pipe in Des Moines is in one of three conditions: new enough to forget, old enough to watch, or old enough to be living on borrowed time. The stock's distribution across those conditions is the metro's building history restated — the pre-1980 districts deep in the third condition, the growth corridors still in the first — and pipe services are how individual homes move between them. A repair returns a watched system to service; a repipe promotes a borrowed-time system back to the first condition wholesale, at a stroke, for another generation. The assessment that chooses between them is short, physical and evidenced: pressure, water colour, and the repair history in the walls. The DES MOINES INTL AP, IA US record — 6,178 heating degree days, 1,070 cooling — is the backdrop Dallas County plumbers plan around.
The repair-or-renew caseload is set by one figure above the rest: 47.0% of Des Moines homes predate 1980, plumbed in the materials now at the end of their service lives. Around Urbandale (46,026 residents) as in the old core, that percentage is not an abstraction — it is the street's plumbing, house by house.
The water heater is the hardest-working appliance in most homes, cycling daily for a decade or more. When output fades or water discolours, the visit tests the components in order — power, elements, thermostat, anode, sediment — because each tells a different story about whether the tank is worth saving.
A water heater's working conditions in Des Moines can be read off this page's climate column: 6,178 heating degree days pulling cold water in through the winter, 1,070 cooling degree days of demand through the long hot season, and a tank cycling between the two without a quiet month in the year. Set that workload against the metro's installation history — heaters fitted in waves as districts were built out — and the service pattern explains itself: repairs and replacements arriving in neighbourhood clusters, each street's tanks reaching their verdicts within a few seasons of one another. Ask in Urbandale and the answer rhymes with Des Moines: same eras, same materials, same calendar of failures.
Heater work in this metro is a fleet problem: the tanks were installed in waves with the subdivisions, and they reach their verdicts in waves too. Johnston (24,196 residents) sits inside one of those waves; the older districts run their own, one tank at a time, inside plumbing a generation older.
Emergencies in Des Moines are answered by local independents, not a dispatch centre: PlumbReach USA routes the call, and the stock it serves — 308,705 homes across 92 ZIP codes — is the stock this page profiles.
Des Moines's drains are cleared by local independents who work this stock weekly: a median build year of 1984 means most lines they open have decades of history in them, and the clearing approach is chosen for the era, not the postcode.
A creeping meter in a Des Moines home is located, not guessed at: the professionals routed here trace the line with instruments and confirm the spot before any floor or wall is opened.
In Des Moines, a toilet that runs all night is a water bill with a sound; the local service replaces the tired internals and checks the flange and supply while the tank is open.
In Des Moines the faucet call is often the first plumbing visit a newer home ever gets — the professionals routed here treat it as an introduction: the fixture fixed, and the home's shutoffs and heater age noted for the record.
Bookings in this metro have a centre of gravity, and it sits on the two patterns this page ranks first: Ageing cast iron sewer lines, then freeze-burst pipes in cold snaps. Everything a local service operation does — the vans' stock, the week's scheduling, the order of this very list — bends around that gravity. A homeowner reading the services above is therefore reading something more specific than a menu: a forecast of what a home like theirs, in a metro built like this one, is most likely to need, in the order it is most likely to need it.

Time is unkind to cast iron below ground. The pipe that carried this metro's post-war growth was laid with a working life in mind, and the calendar has now passed it: the inner wall sheds its lining in flakes, rust blooms narrow the bore, and the rough surface that remains catches everything the household sends down. Flow fades first — a tub that empties slower each year — then the failures arrive: a section that gives way under the yard, a joint that weeps into the soil. Where the metro's housing is oldest, this is not an edge case; it is the standard condition of the stock, arriving street by street as each neighbourhood's pipes reach the same age together. The camera distinguishes rust from roots from collapse, and that distinction sets the job.
There is a temptation to judge an old drain by its kindest day. On its kindest day it still clears, still serves, still seems to argue for another year. Judge it instead by its trend: clearings that come closer together, a tub that drains slower each season, a smell that returns after rain. In the 83,659 pre-1960 homes across this metro, that trend is the pipe's biography being read aloud — corrosion does not pause between visits, and the homes that fare well are the ones whose owners believed the early chapters.
The historical record is the evidence: iron was the default drain material for the whole era that built this metro's core, and the Census counts that era's survivors home by home — 83,659 of them. Camera surveys in those districts confirm the arithmetic often enough that the pattern's ranking here is the least speculative thing on this page.
There is a particular silence after a hard freeze in Des Moines: the pause while households open taps one by one, auditing the night. Most winters, most homes pass. The failures cluster where they always cluster — the addition plumbed in a hurry across a crawl space, the garage wall line, the hose bibb nobody drained — because cold air is a systematic inspector and it works from a list. The record at DES MOINES INTL AP, IA US guarantees the inspection recurs: this is not a freak-weather problem but a standing appointment between the climate and the metro's least-protected pipework, kept every year whether the household remembers it or not.
Prevention, for this pattern, is a geography lesson: the burst never happens in the middle of the heated house. It happens at the perimeter — the wall cavity on the windward side, the run beneath the addition, the pipe the builder routed through the garage to spare six feet of copper. In Des Moines, where 22.0 summer days tempt everyone to forget what 127.9 freezing nights intend, the autumn ritual is short and specific: find every line that leaves the warmth, and do something about it. The households that keep that ritual read about burst pipes the way other people do — as news.
Local exposure, stated plainly: a large stock of homes plumbed before freeze protection was designed-in, standing in a climate that freezes on 127.9 nights a year. Either figure alone is unremarkable; together they describe a metro where burst lines are a seasonal category of call, not an anomaly.
Ownership is the first surprise with a lateral: the buried stretch between the house and the street main typically belongs to the homeowner, however public it feels. The second surprise is its age. In Des Moines, laterals under the older streets were laid for the homes counted in the 145,091 pre-1980 properties — jointed clay or iron, bedded in soil that has swelled and shrunk through 36.55 inches of rain a year ever since. A pipe can be nobody's thought for fifty years and then become the only thought in the house, usually on the evidence of the ground-floor drain in it.
Slope is the lateral's invisible specification. A sewer line does not need much fall — a quarter inch per foot is the classic figure — but it needs it consistently, and ageing takes consistency away: a section settles, a joint steps down, and the line develops a reach where flow slows and solids settle out. That belly then collects a little more each week, narrowing the line from the bottom up. Many a Des Moines lateral diagnosed as 'blocked' is really 'bellyed' — clearable today, certain to collect again. The camera distinguishes the two, and the distinction decides whether the household is booking a cleaning or planning a repair.
Think of the laterals as a hidden census: 308,705 lines, one per home, the oldest of them — serving the 83,659 pre-1960 homes — now in their seventh decade underground. They age in soil that moves with Des Moines's seasons, and their condition surfaces only as symptoms inside the house, which is why so many are discovered late.
Strain is what a decade of mornings does to a tank. Each cycle heats, expands, cools and settles; sediment from every gallon the household has ever drawn settles a fraction at a time into the bottom, where it insulates the burner, lengthens the cycles and bakes the steel. In Des Moines, where demand runs high through the long hot season, that accumulation is the difference between a heater that fades quietly at year twelve and one that lets go at year seven. The appliance looks identical from the closet door. Its account of itself, told in rumblings and recovery times, is not.
Recovery time is the number that runs a household's mornings, and it is the first thing sediment steals. A tank rated to serve a family when new delivers less hot water per heating cycle every year as the sediment layer thickens and the burner's work goes into heating rock instead of water. In Des Moines, where summer demand piles showers, laundry and dishwashing into the same hours, that slow decline shows up as a household quietly rationing hot water without ever deciding to. Flushing the tank returns some of it; a spent anode and a rumbling, scaled tank are the signs the decline has become structural, and the conversation turns to replacement.
Scale the problem by the metro: 308,705 housing units, each with a tank cycling through 1,070 cooling degree days of demand a year. The fleet ages in formation — suburbs built in one boom replace their heaters in one wave — so strain is not randomly distributed across Des Moines; it arrives neighbourhood by neighbourhood, on the building calendar.
This is the season the metro's housing stock is examined by the weather, and the examination is practical: every exposed run, every unheated void, every shutoff nobody has tested. The failures arrive in batches behind the hardest nights and announce themselves at the thaw. The rest of the season grades the slower systems too — heaters working against the coldest incoming water of the year, laterals under frozen ground — but the headline the season writes, year after year, is the sound of water in a wall that should be dry.
Winter's load on this metro can be counted two ways: in the 127.9 freezing nights DES MOINES INTL AP, IA US records, and in the age of the housing that must withstand them — half of it built by 1984 or earlier. Neither number alone predicts a burst; multiplied together, they predict a season. Local plumbers plan their winter around that product, and households in the older districts do well to plan their autumn the same way.
The telltale geography here is generational. Cast iron under a Des Moines street means the street predates the metro's plastic era — the blocks around Des Moines first, the early suburbs second, almost nothing built after the material left standard practice. A homeowner in those blocks owns a drain in its eighth or ninth decade, and the diagnostic question is never whether the iron has corroded — it has — but how far the corrosion has travelled: a section, a run, or the whole line to the street. Cameras answer it street by street, house by house, and the answers in the oldest blocks rhyme closely enough that experienced local plumbers can often predict the footage before they see it.
Strip the pattern down to its inputs and the ranking stops being mysterious: 289,451 households drawing on systems installed across a median build year of 1984, in a climate that swings between 22.0 days of serious heat and 127.9 freezing nights. Whatever pattern a metro with those inputs manufactures most, it manufactures here — the lead position is less a title than a consequence, recalculated from the same public records any sceptic can check.

Read the grid as a building programme spread over a century. The oldest communities sit where the metro began; the youngest are still adding streets at its edge; and Ankeny and West Des Moines, with 70,542 and 69,893 residents, stand for the rings in between. Each ring plumbed in its era's materials, and each is now failing, wearing or holding in its era's characteristic order. The ZIP codes below draw the coverage boundary; the eras inside it draw everything else on this page — the problems ranked, the services ordered, the checks advised.
Beyond the largest communities sit Urbandale (46,026), Waukee (26,974), Johnston (24,196), Altoona (20,592), Clive (18,776) — smaller places across Dallas, Guthrie, Jasper, Madison, Polk, Warren, covered on the same terms. Their housing tends to be older on average than the big suburbs', and their calls follow the older patterns on this page. One routing covers them all: find your ZIP code below and the rest is a phone call.
The metro's weight is not evenly spread. Des Moines holds 212,464 of the 720,331 residents; Ankeny and West Des Moines add 70,542 and 69,893; and the remainder scatters across the smaller places above, some no bigger than a few thousand people. Plumbing follows the weight — most calls come from where most homes are — but era matters more than size: a small community of 1960s housing generates older-system work than a large new subdivision does.
Draw the metro by its paperwork and it resolves into Dallas, Guthrie, Jasper, Madison, Polk, Warren — 6 jurisdictions sharing one housing stock and one weather system. Dallas County holds the historic centre and the densest share of the older homes; the surrounding counties hold the rings of growth around it. Permits and inspections follow those boundaries even though water never does, which is part of why the plumber this page connects you to works these streets specifically.
Beyond the metro line, the nearest covered metros are Waterloo, IA (96 miles away), Iowa City, IA (110 miles) and Cedar Rapids, IA (119 miles) — separate pages, separate profiles, because their housing and weather records are their own. Homeowners near the boundary sit between two datasets; the ZIP list above, not the map's edge, decides which page was written about your stock.
The region around Des Moines is a set of variations on its theme: Waterloo, IA, 96 miles off, runs a median build year of 1966 on a metro population of 169,189; Iowa City, IA (110 miles) medians 1988 on 182,711; Cedar Rapids, IA (119 miles) medians 1976 on 279,285. Nearness is not sameness — a few decades of median build year separate their plumbing as surely as the miles separate their maps.
Ratios tell the metro's story compactly. Renters occupy 30.5% of homes; owners hold the rest. For every home built since 2000 there are 1.4 from before 1980. Spread the stock across the coverage map and each ZIP code carries about 3,355 housing units — the density at which era patterns repeat street after street instead of scattering, and at which a routed round of calls stays inside a few districts.
One line of Des Moines arithmetic — a median home 42 years old · 201,168 owner-occupied homes against 88,283 renter-occupied · 909 pre-1960 homes for every covered ZIP code · a heating-to-cooling degree-day ratio of 5.77 · 928 mm of rain in an average year.
