: Im experiencing four 2 ft. round water areas over my field where waiste water is coming up. We called our local septic guy and he said put up with it until your ready to add a leg to the field. Cost $3500 or more. Well, I aint got $3500.00 What else can I do (myself)? It is an H field with 150 ft. legs. The water spots are showing on the lower side of the field. Field 35 years old. Tanked just pumped.: Many Thanks!!!Around here 35 yrs on a field would be a miracle. Go through house and check toilets carefully for running. Even a little bit can flood a field. make sure nothing like a condensate drain , leaking water heater relief line, icemaker drain and such are connected to septic tank.
