📞 Call or Text (314) 620-4809Every community has its own plumbing challenges. Here's what we see most often in St. Clair and what to watch for in your home.
St. Clair draws on the same regional water supply as the rest of southeast Franklin County, leaving scale buildup in water heaters and fixture aerators.
St. Clair was founded in 1843 as a stagecoach stop, and homes near its historic Main Street — home to the town's famous Hot and Cold water towers — often still run on decades-old original plumbing.
Mature trees throughout St. Clair's older neighborhoods send roots into aging clay and cast iron sewer lines.
Rural and older St. Clair homes with uninsulated crawl spaces are vulnerable to pipe freeze during Missouri cold snaps.
From a leaky faucet to a full water heater replacement — every job handled with the same care and attention to detail.
Water Heater Repair & Replacement — From a failing gas or electric unit to a full replacement, St. Clair homeowners get honest repair-or-replace advice up front. See our water heater repair & replacement page for pricing, timelines, and sizing.
Drain Cleaning — Clogged sinks, tubs, and backed-up main lines are among our most frequent St. Clair calls. See our drain cleaning page for what's involved.
Water Treatment — Franklin County homes often deal with hard water and mineral buildup. We install and service water softeners and purification systems to protect your plumbing. See our water treatment page.
Water Pressure & PRVs — High or low pressure both stress a home's plumbing over time. We test, adjust, and replace pressure-reducing valves for St. Clair homeowners. See our water pressure & PRV page.
Toilets, Fixtures & General Plumbing Repairs — Running toilets, leaky faucets, fixture installs, and everyday repairs make up the rest of a typical St. Clair service call.
When you call Posey Family Plumbing you get Brian — the owner and master plumber. Not a dispatcher, not a receptionist. The person doing the work picks up the phone.
We charge by the job, not the hour. We tell you the price upfront before we start. Whether it takes 15 minutes or 4 hours, your cost is the same as quoted.
We stand behind our work with a one-year warranty on all labor. If something we did isn't right, we come back and make it right — no hassle.
We offer 10% off to all active and veteran military and first responders serving St. Clair and Franklin County. A small thank you for your service.
