The median Cedar Rapids home was built in 1976; 55.5% 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.
Begin where the Census begins, with who lives here and in what: 275,960 people in 113,271 households, owning 74.8% of the homes they live in, in a stock whose median member was built in 1976. Ownership changes the plumbing conversation — owners meet their systems as inheritances, not amenities — and the median date changes its subject: a stock centred on the 1970s is a stock whose original pipework, where it survives, is in its sixth decade and beyond. The sections below are that conversation, organised by the patterns the numbers produce.
Count the older stock by its materials and the metro's maintenance burden comes into focus: iron and clay drains by the tens of thousands of homes, galvanized and early copper supplies in the same walls, fixtures from the first age of mass production still serving in bathrooms across Benton County. None of it failed yesterday; all of it is ageing on schedule together. A homeowner in that stock is not unlucky — they are on time, in a district where the systems were always going to need their generation of attention at once.
Growth wrote this metro's newest plumbing chapter in plastic and concrete: supply and drain lines in modern materials, fixtures by the catalogue, foundations poured as slabs across the subdivisions near Marion and Hiawatha. The chapter is young — its systems have decades in hand — but it is not exempt from the metro's arithmetic: 755 cooling degree days of demand work its heaters hard, and the soil under its slabs moves with the same seasons as the soil under the oldest farmhouse in Benton County.
Over everything sits the weather, and here it is measured rather than described: NOAA's station at CEDAR RAPIDS MUNI AP, IA US averages 48.2 degrees across the year, with 11.9 days reaching 90 or more and 144.2 nights at freezing or below. A buried lateral feels that record as soil that swells and pulls away; a water heater feels it as an unbroken cycle count; an exposed line feels it on the single coldest night. The problem ranking below is what those numbers, crossed with the housing profile, produce for Cedar Rapids specifically.
Housing eras and climate, joined — the two datasets every section of this page is built from.
Lay the eras side by side instead: 30.4% pre-1960 (37,078 homes), 25.1% from 1960-1979 (30,613), 20.2% from 1980-1999 (24,637), and 24.3% since 2000 (29,638). No single era tells the story — the proportions among them do, and those proportions are different in every metro this site covers.
Vintage is destiny in this metro. With the pre-1960 band the largest of the four, the centre of gravity of Cedar Rapids's plumbing sits in systems that have already outlived their design lives — iron drains gone rough inside, steel supplies thinned by their own rust, clay joints shifted by seven decades of soil. The later bands matter, and the post-2000 subdivisions will write their own chapter in time, but the calls that define plumbing here come disproportionately from the oldest streets, and they will keep coming until that stock is renewed pipe by pipe.
The second band in the table is the 1960-1979 stock: 30,613 homes, 25.1% of the metro. It is the transition generation — copper arriving, galvanized lingering, drains mixed street by street — and it supplies Cedar Rapids with its most diagnostic plumbing: two homes of the same year needing opposite answers, decided by what the builder happened to specify.
The climate half of the profile, from CEDAR RAPIDS MUNI AP, IA US: 6,824 heating degree days against 755 cooling degree days, 35.91 inches of precipitation, an average temperature of 48.2 degrees. Read together, those figures describe the loads: how hard heaters cycle, how often the soil around buried lines swells and shrinks, and how much of the year exposed pipework spends anywhere near freezing — 144.2 nights at or below it, against 11.9 days at 90 or above.
Hold the two halves together and the rest of this page explains itself: the problems ranked highest here are the ones where Cedar Rapids'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.

Read a cast iron drain's age in its symptoms and the progression is orderly. First the line slows — not blocked, just reluctant, as scale roughens the bore and catches what passes. Then the complaints localise: one branch backing up, then another, as sections of the run reach their own stages of narrowing. In Cedar Rapids's oldest districts that progression plays out across whole streets of the 1970s housing at once, because the lines were laid in the same years from the same material. The camera distinguishes the stages house by house: a bore narrowed by scale that cleaning can restore, against a wall thinned and cracked past any cleaning's help.
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 37,078 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.
Put a number on it locally: roughly 37,078 homes in the Cedar Rapids metro were built before 1960, when cast iron was the default drain material — and cast iron installed then has now been underground for six decades or more. Not every one of those lines has failed, and plenty test sound on a camera, but the population of pipes at risk here is counted in the tens of thousands of homes, which is why this pattern sits where it does on this page.
Water expands when it freezes, and a closed pipe gives that expansion nowhere honourable to go. The split usually forms where the ice plug's pressure peaks — often not where the freeze itself sits — which is why a burst can hide in a warm stretch of wall downstream of the frozen one. Cedar Rapids's exposure concentrates where lines leave the heated envelope: the pre-1980 districts around Cedar Rapids, garages, crawl spaces, additions. On the coldest nights of the year, the metro's plumbing is only as strong as its least-protected run, and the thaw reads out the verdict house by house.
The burst itself usually happens quietly, inside a wall or under a floor, during the coldest hours — but the flood waits for the thaw. Ice seals the split it made, and only when temperatures rise and the ice lets go does the water start moving into the house. That delay is why freeze damage so often greets a Cedar Rapids household in the morning or on return from a trip away. It is also why the checks after a hard freeze matter: pressure oddly low, a meter turning with nothing running, a damp patch at a wall base. Catch the split at the weep stage and the repair is a pipe; catch it after the thaw and it is a room.
Two local numbers frame the risk: 144.2 nights a year at or below freezing at CEDAR RAPIDS MUNI AP, IA US, against a housing stock whose median home dates to 1976 — plumbed, much of it, before routing lines away from cold air was standard practice. Exposure is the product of those two numbers, and in this metro the product is large.
Every lateral in Cedar Rapids is a private road with a public destination, and like a road it wears where the traffic and the ground conspire: at the joints. Sections laid generations ago were joined to the standards of their day, and the decades since have worked each joint individually — a fraction of movement here, a root hair there. The ground-floor fixtures report the cumulative result. Sewer service is the survey of that road, cleanout to street, and its recommendations scale with the survey: a joint renewed, a section replaced, or — where the whole run has given up — a new road laid on the old one's line.
A lateral gives decades of silence and then a short conversation. The conversation usually starts with the ground-floor drain in the house and escalates through the cleanout to the camera — and the camera's footage settles every argument about whether the line is blocked or broken. Across Cedar Rapids, the laterals entering that conversation now are the ones buried when the metro's median home went up, in 1976. They were built to outlast their mortgages, and they have; the question the footage answers is how much further the same pipe can honestly be asked to go.
The census figures draw the map: 37,078 homes from before 1960 and a median build year of 1976 mean the typical lateral in Cedar Rapids has been buried for decades, and the oldest have passed the service life their materials were expected to give. Multiply one buried line by 121,966 housing units and the pattern's rank on this page stops being surprising.
Living with a real winter, as Cedar Rapids does, means the season has a rhythm: the first hard freeze finds the unprepared lines, mid-winter tests the insulation, and the late thaws reveal whatever split quietly weeks before. Households that drain exterior lines in autumn and keep a trickle running on the coldest nights get through most winters with nothing to report.
The numbers behind the season here: 144.2 nights a year at or below freezing at CEDAR RAPIDS MUNI AP, IA US, against a housing stock whose median build year is 1976. Every winter writes the same exam for Cedar Rapids's older pipes, and every winter some of them — usually in the the 1970s districts first — fail it.
The telltale geography here is generational. Cast iron under a Cedar Rapids street means the street predates the metro's plastic era — the blocks around Cedar Rapids 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.
Why here and not everywhere: Cedar Rapids pairs 67,691 pre-1980 homes with 11.9 days a year at 90 degrees or more and 144.2 nights below freezing. Every metro pairs its housing with its weather somehow; this particular pairing is what puts the pattern where it sits on this page's list, ahead of problems that dominate metros built in other decades, under other skies.
The first visit follows a short, diagnostic list — each item ruling a branch of the problem in or out:
Listed in the order this metro's housing and climate data supports.
A house can survive a lot of plumbing faults, but not a failed path to the street. Sewer services confront the lateral directly — inspected by camera, cleared where clearing suffices, excavated and renewed where the pipe has structurally given up. The footage, shown to the homeowner, is the basis of every recommendation.
The camera footage is where Cedar Rapids's sewer conversations get honest. From the surface, a backup is a backup; on the screen, the metro's whole history is visible — clay joints shouldered apart by decades of soil movement, cast iron scaled to half its width, a plastic line in a newer subdivision bellied where its bedding settled. Benton County's older laterals and the growth areas' young ones fail in their own dialects, and the repair that follows the footage — sectional, partial, or the full run to the street — is the one the pipe itself argues for. It is why two Cedar Rapids homes of the same age, on different streets, so often need the same visit in the same year.
Under Cedar Rapids lie 121,966 laterals, one per housing unit, and the oldest of them — beneath the 37,078 pre-1960 homes — have been underground since the metro was a fraction of its present size. The camera diary in Marion and the old core is written by that buried generation.
Pipes age by material: galvanized chokes with rust, copper pits into pinholes, early plastic turns brittle. Repair answers the isolated failure; repiping replaces a system whose failures have become a rhythm, rerunning supply lines in modern material while the house stays liveable around the work.
The repiping conversation in Cedar Rapids starts with its housing data: median build year 1976, 55.5% of homes from before 1980, and whole districts plumbed in materials that are now at or past their expected service lives. Galvanized lines in the older neighbourhoods have been narrowing from the inside for decades; the symptom homeowners notice — pressure fading year by year — is the pipe's inner diameter closing. One pinhole in that stock is an event; the third is a pattern, and the plumbers who work Cedar Rapids and the older core will say so plainly rather than sell a fourth repair. Locally the workload concentrates where the stock is oldest — the districts built around the 1970s first.
Pipe work divides by era in this metro with unusual neatness: renewal conversations in the 67,691 pre-1980 homes, sectional repairs in the middle ring, and near-silence from the 29,638 post-2000 homes whose lines are still young. A call from Anamosa can sit in any of the three bands; the home's build year says which before the door opens.
Heater work in Cedar Rapids is workload work: 11.9 hot days and 6,824 heating degree days a year cycle the metro's tanks hard, and the local professionals routed here size, flush and replace against that record.
Emergencies in Cedar Rapids are answered by local independents, not a dispatch centre: PlumbReach USA routes the call, and the stock it serves — 121,966 homes across 49 ZIP codes — is the stock this page profiles.
Cedar Rapids's drains are cleared by local independents who work this stock weekly: a median build year of 1976 means most lines they open have decades of history in them, and the clearing approach is chosen for the era, not the postcode.
The meter test starts it in Cedar Rapids as everywhere; what follows is local — knowing which of Benton, Jones, Linn' eras hide lines in slabs, which in crawl spaces, and where the soil movement at CEDAR RAPIDS MUNI AP, IA US's record makes joints let go.
In Cedar Rapids, 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 Cedar Rapids 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.
Ask where this metro's plumbing diary fills up and the answer is a short story: Ageing cast iron sewer lines first, freeze-burst pipes in cold snaps close behind, and the services that answer them doing the bulk of the booked work. Everything else on the list above is the supporting cast — necessary, frequent enough, but not what Cedar Rapids's housing stock, at its age and in its climate, principally demands. Read the service list as a weather report for the metro's pipes and it stops looking like a catalogue.

A metro is a federation of building decades wearing one name, and the grid above is Cedar Rapids's federation: Cedar Rapids at the centre, Marion (41,690 residents) and Hiawatha (7,178) in the next ring, and the smaller communities beyond, down to places a few thousand households deep. What unites them is one climate record and one routing; what divides them is the year their streets were plumbed. The ZIP list that follows is the practical definition of that federation — if your code is on it, your home's era is part of the data this page was built from.
Also on the Cedar Rapids map: Anamosa (5,553), Vinton (4,948), Mount Vernon (4,551), Monticello (4,055), Robins (3,349) — communities spread across Benton, Jones, Linn, each with housing from its own growth years. A plumber routed through PlumbReach USA to any of them is working from this same page: the metro data does not change at the city limit, but the housing on your street — its age, its materials, its soil — is what the visit is really about.
Start with Cedar Rapids itself: 136,859 residents, 49.6% of the metro — the centre the rest of the map orbits. Marion (41,690) and Hiawatha (7,178) form the next ring out, housing with its own building decades and its own plumbing generations. Beyond them the metro thins into the smaller communities in the grid above, each a few thousand households deep — small in population, identical in one respect: their pipes answer to the same eras and the same weather as the big city's.
One metro, 3 county lines drawn through it: Benton, Jones, Linn. The lines are invisible to the water and the weather, but they structure everything administrative around a plumbing job — which office permits it, which inspector signs it, which code edition applies. Benton County, at the centre, carries the oldest housing and the heaviest share of the work this page describes; its neighbours carry the growth. A routed local plumber navigates the patchwork so the homeowner does not have to.
Beyond the metro line, the nearest covered metros are Iowa City, IA (41 miles away), Waterloo, IA (55 miles) and Davenport, IA (73 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 Cedar Rapids is a set of variations on its theme: Iowa City, IA, 41 miles off, runs a median build year of 1988 on a metro population of 182,711; Waterloo, IA (55 miles) medians 1966 on 169,189; Davenport, IA (73 miles) medians 1966 on 380,452. Nearness is not sameness — a few decades of median build year separate their plumbing as surely as the miles separate their maps.
The stock has a shape as well as a size. Owners hold 74.8% of it and renters 25.2%, a split that decides who notices a drip first and who arranges the repair. The generations split 2.3-to-one in favour of the pre-1980 homes. And the map divides into 14 named communities across Benton, Jones, Linn, each carrying its era's share of the 121,966 housing units the Census counts here.
One line of Cedar Rapids arithmetic — a median home 50 years old · 84,727 owner-occupied homes against 28,544 renter-occupied · 757 pre-1960 homes for every covered ZIP code · a heating-to-cooling degree-day ratio of 9.04 · 912 mm of rain in an average year.
