    Tips: Signs You Need A New Sewage Pump

    Dealing with dirty water. One of the first things to be on the lookout for is dirty water running through your systems. The whole purpose of having a sewage pump, no matter the exact type, is to regularly filter clean, clear water into your operations. When that isn't happening and you're getting dirty, murky water instead.

    Sewage pump won't start or struggles to start. It is also an issue if it struggles or is slow to start. There are a variety of reasons that this issue could pop up. It could be the result of anything from electrical problems to frayed wires to a blown fuse. It could also be the case that your pump has simply "given out."

    Sewage pump is constantly cycling. If you find that your pump constantly seems to be cycling, so much so that you can never really determine what stage it is. The issue could be a poorly or improperly adjusted switch, a burnt-out motor, or issues communicating commands to turn on or off.
