Request Pump Service
Describe the building, the pump and what it is doing.
Which pump do you have?
Sump pump
Lifts groundwater and clear water from a pit (foundation and below-grade floor drains) and pumps it out of the building.
Sewage ejector or grinder lift station
Where fixtures sit below the sewer, drains can't flow by gravity. The plumbing code requires a covered, vented sump with automatic pumping, a check valve and a full-open valve on the discharge. Pumps that receive toilets must pass 2-inch solids; grinder pumps cut solids so they can use a smaller discharge. Duplex systems alternate two pumps.
Booster pump
When city pressure isn't enough for upper floors or demanding fixtures, a booster system raises it. The code requires a low-pressure cutoff that stops the pump if suction pressure falls to 10 psi or less.
Warning signs
- High-water alarm sounding or alarm light on
- Pump runs constantly, short-cycles or won't shut off
- Grinding, humming or heavy vibration
- Sewer odor near the pit
- Water or sewage at the lowest floor drains
- Weak or surging pressure on upper floors
How we service it
- 1
Diagnose
We check floats and level controls, the alarm, check valve and discharge piping, and find out why it failed.
- 2
Repair or replace
A float, check valve or pump, or a full replacement, sized for the building.
- 3
Keep it running
Add the pump to a planned maintenance schedule with alarm and float testing.
We installed a duplex grinder lift station and sump pump at a dental surgical center in Richmond Heights.
For site lift stations and force mains outside the building, Kuesel, our sister company under Kuesel Holding Company, works with us as one team.

Commercial Pump Service FAQ
What's the difference between a sump pump and a sewage ejector?
A sump pump moves groundwater and clear water. A sewage ejector moves wastewater from toilets and fixtures below the sewer, so it must handle solids and sits in a sealed, vented pit.
Our high-water alarm is going off. What should we do?
Stop using fixtures that drain to that pit, keep people away from any sewage, and call 636-978-0120 with the location and what the pump is doing.
How often should pumps be checked?
Follow the manufacturer's guidance. Many facilities add pumps and alarms to an annual plan so problems are found before a backup.
Do you work on fire pumps?
No. This page covers sump, sewage and domestic water booster pumps. Fire pumps are handled by fire protection contractors.
