We have a gurgling noise mainly from the kitchen, and laundry sinks. There does not seem to be a problem with waste getting away, but the noise is frequent and quite loud. Particularly noisy when using shower or washing machine. We are on septic tank system. Any suggestions for fixing would be appreciated.
Sounds like a partical blockage starting Or poor venting.
Ever take a 2 liter bottle pour it upside down? PLOP PLOP PLOP now put a small hole in the top and then try pouring it
Wow equalized pressure and no vacuum. That is what a proper vent does.
Check your vent terminal (roof vent) and then possibly have your waste/soil lines water jetted to remove old debris build up restricting the full flow on the internal piping [Edited by SylvanLMP on 14 March 2001]
