Common Sewage Pump Problems

Filed under: Uncategorized — admin @ 10:26 pm

Sewage pumps allow us to build homes in areas where it was once not possible because of the grade. Many municipal sewer lines work because of gravity. At one time, a house could not be built below the sewer because there was no way to get the waste uphill into the main sewer. In today’s world it is quite common for homes to be equipped with a sewage pump to eliminate this problem. However, there are times when these sewage pumps can cause problems. Raw sewage backing up if your sewage pump quits can not only be a headache but can also be a health risk. These problems must be corrected immediately before the plumbing in your household can be used again. The most common problems which cause a sewage pump to stop working is a freeze, clotting, and blocking.

Many sewage pumps are located outside of a home somewhere in the yard. Many parts of the country will experience harsh winters in which the ground will freeze to a certain depth. This frost line must be noted when a sewage pump is installed for a residence. However, there are times when a sewage pump will not be buried deep enough to avoid this freeze. This can cause the waste water in the holding tank of the sewage pump to freeze and not be able to be pumped out. If this is the case, then the tank of the sewage pump will need to be dug up and buried deeper to avoid future freezes.

Clotting is another common problem with sewage pumps. Clotting occurs when a large piece of debris becomes wedged in the pump. This large piece of debris will then start to trap other smaller pieces of debris. In turn, this will lead to finer materials such as dirt and silt to accumulate until the pump is eventually clogged. Clotting may result in the pump starting to run slower and slower. If this is noticed a call to the plumber should be made immediately.

Finally, another common problem can be blocking. This happens when debris or grease accumulates on the float and causes the sewage pump to either continuously run or not run at all. A backup of sewage is usually the first indication that blocking is occurring.

It is always important to call a licensed plumber at the first sign of a problem with your sewage pump, this can often lead to an easy repair and avoid further extensive problems in the future.
