2017 Tab 320 Toilet line blew

Beckblaze9 · August 2023

Hi,
My line has separated at the back of the toilet. It looks like it was previously glued on (bought this used a few years ago) Is gluing the best way to repair it?

See photo. Thanks!

That is the inlet to the "toilet valve" on the back of the toilet. You may have to replace the entire valve, but I'm not sure on that.

This thread has the Thetford parts manual and will point you in the right direction for the right part.

Thank you!!!

@Beckblaze9 same thing happened to us. We did a simple valve assembly replacement. Either way (see response to your toilet replacement inquiry) requires removal of the toilet.

Good luck!

For prevention in areas where freezing can be an issue, I suggest flushing the toilet line with antifreeze after blowing out the lines.
First, install a shutoff valve on your toilet's water supply line. Then you can push antifreeze through it.
For flushing, I keep a pair of short hoses to temporarily attach to each side of the water pump, connecting the output side to the toilet line & input side in the jug of antifreeze. This also takes care of winterizing the pump, and I leave these short hoses on until spring dewinterizing.

I was preparing for a trip yesterday and discovered precisely this issue with my 2015 T@B S-Maxx. Seems like this part could be redesigned to avoid this issue, but maybe that's not going to happen at this point.

Luckily, a dealer 30 minutes from here has two valve kits in stock. 3X the price of you-know-where, but when you need it, you need it!

Thanks for this thread. The information on this forum is just invaluable.
