Commercial Pit Pump Replacement in St. Louis
Commercial buildings often have elevator pits, parking garage drains and mechanical room sumps. These require pumps rated for higher flow and sometimes oil-sensing controls. We replace commercial pumps and alarms to meet code and insurance requirements. Duplex systems with alternating pumps provide a backup. We schedule work to avoid interrupting operations.

Submersible Sump Pump Replacement in St. Louis
Submersible sump pumps are popular in St. Louis for their quiet operation and ability to sit fully submerged in the sump pit. When replacing a submersible pump, we carefully remove the old unit, clean the pit and install a new, appropriately sized pump. We make sure the check valve and discharge piping are correctly connected to prevent backflow and improve efficiency. That is crucial for handling heavy rainfall.
Battery Backup Sump Pump System Installation in St. Louis
A working sump pump and a backwater valve are smart protection for any home with a finished basement. Power outages during severe storms can leave standard sump pumps useless. Our battery backup sump pump system installation in St. Louis provides an essential layer of protection. We add a secondary, battery-powered pump that automatically activates if the primary power fails, keeping flood protection running even without electricity. This is a valuable upgrade for many homes.
Zoeller Sump Pump Replacement in St. Louis, MO
Zoeller pumps are known for their reliability and heavy-duty construction, making them a top choice for many St. Louis, MO homeowners. FGV Plumbing specializes in Zoeller sump pump replacement, so you get a high-quality, long-lasting unit. We can replace your existing Zoeller pump with a comparable model or upgrade you to a more powerful one to meet your needs and local conditions.
Commercial Sump Pump Replacement in St. Louis
Businesses in St. Louis also rely on effective sump pump systems to protect their commercial properties. We provide dedicated commercial sump pump replacement services, handling larger, more complex systems designed for industrial or multi-unit buildings. Our team keeps disruption to your operations low while installing a robust pump capable of handling higher volumes of water.
Float Switch and Check Valve Replacement in St. Louis
Many sump pump failures start with a stuck float switch or a leaking check valve. A failed check valve lets water flow back into the pit and causes the pump to short cycle. We install new check valves with every pump replacement and verify the switch moves without binding. Vertical float switches work well in tight pits. Tethered floats work best in larger pits.
Sewage Ejector Pump Replacement in St. Louis
Basement bathrooms and laundry rooms below the sewer line need sewage ejector pumps instead of sump pumps. These pumps handle solids and must be installed in sealed, vented basins. We replace ejector pumps with models rated for two inch solids. We also check the basin seal, vent and discharge check valve. Proper installation stops sewer gas odors.
