Blocked waste water outlet on our T6

[Cali Phillip]

I agree. Normal.

Mine got blocked up with just kids spitting toothpaste down it. Now banned! I presume it’s the pipe immediately under the plug hole that was clogged. Had to use full drain cleaner in the end. The hardcore acid type stuff. All the the pipes are normal plumbing plastic so resistant to boiling water and drain cleaner. It got a lot better after that.

It’s never what you could call fast!

Never considered tooth paste although soap from hand washing with minimal water probably does the same.
Unblocking the drain was job 2 today after the gas regulator died after just 3 yrs use.

I cleaned out the sink drain a few weeks ago, maybe that dislodged some debris.
A combination of hot water, detergent and closing the drain then putting the hose in effectively pressuring the tank via the overflow seemed to work after. a few goes.
Once unblocked ran 20litres of near boiling water and detergent though.

I now have a sink strainer made for a tea strainer to ensure no debris gets into the tank.
