We have had a low flow toilet on our second floor for ten years.
Just recently it started acting up and has not been reliable since.
Our plumber has suggested that it is because the aging pipes in our old
farmhouse are shifting away from their original vertical position in the
Any advice would be appreciated.
Just a thought. Old plumbing was designed for high flow toilets. Is it possible
that long term low flows has allowed debris to settle, partially blocking the
drain. It might be interesting to dump a couple 5 gallon buckets of water
quickly down the toilet and see if that helps.
I can't think of any reason why old pipes would suddenly decide to shift position
unless there was water damage or an earthquake or something.
Think there was a post or two commenting that roots got into the drain
then water leaks eroded the soil underneath allowing the drain to drop
and cause subsequent problems. Had a plumber here recently for slow
sink drain and he insisted on sending his new camera down the mainline
for show & tell. Found a few small roots that we'll take care of with
the semiannual Root Kill flush.
