I had water backing into my basement yesterday and opened my septic tank and found that my filter was dirty. Cleaned it and I'm all good now. However, before I opened the tank, I accidentally opened my pump chamber. The pump was running, which is fine, but I noticed some water spraying out of the pipe that leads from the pump to the septic tank. It was bigger than a pin hole, but not as big as a hose spraying. I wasn't sure if that's by design (some sort of pressure release) or what. I assume it's pvc, so thought it would be unusual for it leak like that (a hole just suddenly appearing). Anyone know if this is by design or if I shoukd be calling someone?
