Hello,

Whenever we flush the loo, the pipe thumps a few times as if we flushed a loaf of bread-even if it's just Comet and water. Also, the bathroom smells like a sewer no matter how much cleaning we do.

We did some work in the floor below the bathroom a few months back, and the ceiling is still wide open-all the pipes are visible and not leaking.

Any ideas?

Thanks!

What kind of work was done. Sounds like maybe a venting problem

[Rocketbrady]

Thanks for the reply.

We replaced the old lines to the sink and the shower. We didn't go near the toilet plumbing.

I was wondering about that, though. Could the vent have somehow become plugged from above? Bird?

Does the thumping come while the water is draining out of the toilet, while the tank is refilling of after the tank has refilled?

Very possible, also try draining the lines (water) with all taps open(shut off main), then slowly turn water back on and turn off taps one at a time starting from bottom -up. This shoulget rid of any possible air trap in your water lines. Could the toilet have been flushed with the water off? This somettimes cause an air trap. This time do not flush but pour down a bucket of water in the toilet to fill line with water as you turn the water back on. Good luck.

Immediately upon flushing, it sounds as if sneakers are traveling down our pipes. It's definitely not in the tank, or the re-fill process.

Thanks again.

Try the draining, pretty sure you have an air trap.

[Rocketbrady]

Thank you both.

Thank you both very much. I will try it.

While the work was in progress was any drain lines opened?
