Union, MO Plumbing Repiping
Around Union, repiping done right accounts for what the local environment does to plumbing. Set in Missouri's humid subtropical region — a humid subtropical climate — long, hot, muggy summers, mild winters, heavy thunderstorms, and high year-round humidity — homes here contend with high year-round humidity that sweats and corrodes copper pipe and summer heat and moisture that strain water heaters, so we spec corrosion- and climate-rated pipe, fittings, and fixtures rather than whatever's cheapest on the shelf. The failures we see most around Franklin County are sewer backups after heavy thunderstorms and pitted galvanized pipe on older homes, and our repiping trucks are stocked for them.
Union's climate story is Missouri's humid subtropical region — a humid subtropical climate — long, hot, muggy summers, mild winters, heavy thunderstorms, and high year-round humidity. On a home's plumbing that translates to high year-round humidity that sweats and corrodes copper pipe, summer heat and moisture that strain water heaters, and frequent thunderstorms that back up storm drains and sewers — which is why we spec corrosion- and freeze-rated pipe, fittings, and equipment for the local climate.
Union's most common plumbing failures are sewer backups after heavy thunderstorms, pitted galvanized pipe on older homes, and high water pressure straining aging fittings. None of it is coincidence — 101 days below freezing a year freeze and split supply lines and outdoor spigots, 15 inches of snow and a long frost season keep buried lines cold enough to crack at the joints, 38 days above 90°F push water heaters and expansion tanks to their limit, and 66% are detached houses with their own service lateral, water heater, and outdoor spigots to maintain. We stock every Union truck for precisely this corrosion and wear, and fix it in a single visit.
A whole-home repipe is the permanent fix for a house whose supply pipes have reached end-of-life — original galvanized steel closing up and rusting the water, polybutylene from the 1980s–90s failing without warning at the fittings, or copper that keeps developing pinhole leaks on run after run. Instead of chasing one leak at a time inside the walls, a repipe replaces the entire supply distribution in one planned project, restores full pressure to every fixture, and resets the clock on the most failure-prone system in the house.
We repipe in PEX-A and type-L copper. PEX-A is flexible, freeze-tolerant, corrosion-proof, and fast to route with fewer fittings inside the walls, which means fewer potential leak points and a lower cost; type-L copper is rigid, time-proven, and preferred where exposed runs, high heat, or local code call for it. Our plumbers map the runs, open the minimum number of access points, pull the new lines, tie in every fixture, and pressure-test the whole system before anything is closed.
Repiping is turn-key: free on-site consultation, a written quote good for 30 days, permits pulled and the municipal inspection scheduled, drywall access points patched and textured, and the water restored the same day in most single-story homes. Financing is available through Synchrony at 0% APR for the first 12 months on projects over $1,500, and the work carries a 10-year workmanship guarantee on top of the pipe manufacturer's warranty.

Signs you need repiping
Locally in Union, it usually surfaces as pitted galvanized pipe on older homes.
Rusty or discolored water
Brown water at the first draw, or a metallic taste, means galvanized pipe is corroding from the inside. When it's happening at multiple fixtures, the whole distribution is due.
Weak pressure throughout the house
When every fixture runs weak, not just one, the supply pipe has narrowed from the inside across the whole home. New full-bore pipe restores the pressure the fixtures were designed for.
Repeated pinhole leaks
A copper system that leaks a pinhole, gets patched, then leaks another one on a different run within months has aggressive water eating it everywhere. Patching becomes a losing game — a repipe ends it.
Home built before 1975
Homes from before the mid-1970s often still run original galvanized steel well past its 50-year life. If it's never been repiped, the pipe is living on borrowed time.
Polybutylene pipe anywhere in the home
Gray polybutylene supply pipe becomes brittle and fails at the fittings unpredictably. Insurers often won't cover it, and a proactive repipe removes the liability before it lets go.
Why it happens & what we fix
Aggressive-water copper pitting
Acidic or high-velocity water pits copper from the inside until pinholes weep through, clustering on hot and recirculation lines. When it recurs across runs, the system is the problem.
Polybutylene brittleness
Poly pipe and its acetal fittings degrade with exposure to chlorinated water and become brittle, failing at the joints without warning. Whole-home replacement is the only reliable fix.
Galvanized steel at end-of-life
Galvanized pipe corrodes and closes from the inside over decades until flow drops and the water rusts. There's no reversing it — the material has simply reached the end of its service life.
Hard-water and coastal corrosion
Mineral scale narrows pipe from the inside while coastal salt air corrodes it from the outside, and both accelerate a supply system toward whole-home failure.
Undersized original distribution
Homes plumbed with undersized trunk lines never delivered proper pressure to simultaneous fixtures. A repipe is the chance to correct the sizing, not just replace the pipe.
Weather wear, Union edition
Being in Missouri's humid subtropical region means high year-round humidity that sweats and corrodes copper pipe; in Union the result we see most is sewer backups after heavy thunderstorms, and the trucks are stocked for it.
