Commercial Restroom Fixture Repair in St. Louis

What we repair
- Toilets: flush-valve toilets that run, double-flush or won't flush; loose or leaking bowls and seals.
- Urinals: running or weak flushes, leaks at the flush valve, slow drains.
- Flush valves (flushometers): diaphragm and piston kits, handles, vacuum breakers and control stops, manual or sensor.
- Faucets: drips, metering faucets that shut off too fast or run on, cartridges, aerators and sensor faucets.
- Stops and supplies, so one fixture can be shut off without closing the whole restroom.
Common calls
- Toilet or urinal won't stop running: usually a worn diaphragm or piston, debris in the valve, or a failed sensor or solenoid.
- Weak flush: often a partly closed control stop, the wrong flush-volume part, or low water pressure.
- Leak at the handle or under the valve: worn seals or a loose connection.
- Clogs that keep coming back in the same restroom: see commercial drain cleaning.
How we repair it

Test and record
Flush and run-test, check for leaks, and note other fixtures that need attention so they can go on a preventive maintenance visit.
Code and accessibility notes
- Replacement fixtures must meet the plumbing code's water limits. IPC Table 604.4 sets 1.6 gallons per flush for water closets, 1.0 for urinals, and 0.5 gpm for public lavatory faucets (0.25 gallon per cycle for metering faucets).
- In accessible toilets and urinals, the 2010 ADA Standards (604.6, 605.4) allow automatic or hand-operated flush controls; hand controls must work with one hand, without tight grasping or twisting, and with no more than 5 pounds of force. On accessible toilets the control goes on the open side.
- If the restroom layout needs to change, see ADA restroom retrofits. For building-wide sensor fixture programs, see auto-flush and sensor fixtures.

Local jurisdictions adopt the code with their own amendments.
Restroom Fixture Repair FAQ
A toilet is overflowing after hours. What should we do?
Close the stop valve on the fixture or its flush valve, keep people away from the water, and call 636-978-0120. Scheduled service Monday–Friday, 7am–4pm. 24/7 emergency calls answered. Nights and weekends are billed at higher rates.
Can a flush valve be rebuilt instead of replaced?
Often, yes. Most failures are worn internal parts that a rebuild kit fixes. We replace the valve when the body is damaged or parts aren't available.
Do you repair sensor fixtures?
Yes: batteries, sensors, solenoids and range settings. For ongoing service across many restrooms, see our auto-flush and sensor fixture page.
Can you fix several restrooms or buildings in one visit?
Yes. Send a list of the fixtures and where they are, and we'll plan the visit. Recurring checks can go on a preventive maintenance plan.
