Note: We were forced to introduce low volume flush toilets two years ago but the powers that be didn’t increase the slope of the main piping system. The flushing action has been acceptable but not great.

For the last year I have been pouring 5 gallons of boiling water down the drain every week followed 10 minutes later by 4 or 5 flushes. That seemed to clean out any deposits that the low flow rate didn’t carry away.

Probably not a good idea considering the seal is made of wax.
