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.

A further thread resurrection here. The magic of the forum search button.
Mine recently blocked for the first time in 7 years of ownership. This thread has been very helpful as was the parts diagram.
I did the baking soda, vinegar and boiling water but it in fact blocked it more. If I had patience it might have dissolved it.
I didn’t.
I took the upper, over flow pipe off the valve after removing the second access hatch for the fridge compressor. I used a 20cm zip tie and bent the tip slightly. Because it is relatively stiff it was possible to guide the tip into the valve and pass it into the waste tank exit. Hey presto a massive gush of water (out of the lower tube) if the tank is very full the there must be a risk of the pressure pushing water upwards when it finally goes but fortunately not in this case.
As an added bonus the baking soda and vinegar has also cleared the sink u-bend
and it is now running better than it has in ages.
The toothpaste theory might hold some truth as I have always tried to avoid food residue down the sink.

Treat it just like a kitchen sink. Drain unblocked from Tesco followed by a kettle or two of boiling water.
