Grinder Pump Repair

Sewage Grinder Pump

Emergency plumbing problems never happen when it is convenient. The sewage grinder pump is a hard working piece of plumbing equipment that grinds up all the sewage from your home and pumps it into the city sewer. City sewage systems use forced main sewage systems due to excessive elevation changes. The sewage grinder pump lifts waste up hills to pushes it to the sewage treatment plant.

The sewage grinder pump should be installed with an alarm. The alarm may be a flashing red light, a buzzer or both. Not all sewage pumps are the same and not all sewage pumps are allowed in every city. The most commonly used grinder pumps in the Lago Vista and Leander area’s are 2hp grinder pumps.

There are a few different brands that have been installed in this area such as

The most common problem we see when servicing grinder pumps are foreign objects such as:



Wet Wipes

Shop Towels

Scrubber Pads


Cigarette filters


Wash Clothes


These items cause damage to the sewage pump and will result in emergency sewage pump repair or replacement. The life of the sewage pump is determined by how well you maintain the sewage system and how well you protect from foreign objects.

The most common repair we make to a sewage pump is unjamming it. The process to unjam is messy and can be costly on older equipment . The piping inside the basin should be of corrosion resistant metal or pressure rated PVC. The basin should be flushed and rinsed out once annually to promote reliable operation.

Not all plumbers are qualified to work on sewage pumps. The best sewage grinder pump repair technicians are not afraid to get dirty. The sewage grinder pump has to be removed from the basin to be unjammed. The impeller at the bottom of the sewage pump is removed to free of foreign objects. The sewage grinder pump is a submersible pump that works best when kept submerged in water. The sewage pumps operate by floats that switch the pump on and off.

When the floats become tangled or covered in grease they do not work properly causing the pump to malfunction.

Common Problems caused when floats hang up:

False Alarm Signals

Pump fails to operate properly and short cycles

Pump may continuously run causing thermal over load

Pump may not turn on causing sewage back up

To avoid damage to your sewage grinder pump please perform annual maintenance consisting of cleaning the pump basin and the floats.
