Tecma Toilet - Spare Parts to Carry?

[rbr]

Our coach just has one bath and the toilet is a Thetford Tecma macerator type. I want to carry spare parts for this device () and I'm curious if anyone has info or experience on what parts are likely to fail?

The rubber cover is tearing on our button panel so I've ordered another (36287) and will keep the old one as a spare.

I will also order the full Pump/Motor/Discharge pipe kit (38056).

Are any of the other parts likely to fail?

Controller? (36398)
Solenoid Valve? (38649)
other plumbing parts???

Thanks for any advice!

The one failure I had was with the solenoid/pump...it has a screen in it that over time can collect silicates. We didn't have water coming in to the toilet, took the item out, blew the silicate out of the screen, put it back together, and the water now flowed.

That is the only failure I am aware of...not that many posts on here of the Tech failing that I recall. Thetford Aria II Deluxe...more likely. I'd like to have my macerator toilet back. JMHO
