We hear the same toilet sounds, in both toilets. We noticed a problem when we had the dishwasher going, a child in the shower and the washer finishing a load. We are on septic. We have never had a problem in the past with all the machines running. Now, when our son was in the shower this AM, the toilet made the blub blub noise. I had showered before him, but no other machines were running. We had the tank pumped about 7 years ago, there were no problems at that time. We just did it because we thought we needed to due to what some were saying.. ya know.. peer pressure?

Ideas? PLEASE let us know! We're ready to dig it up and have it pumped...

Thanks!

I would certainly start by having the septic tank pumped, after seven years, its most likely full. Let us know if this solves the problem.
