Thetford Toilet Flush Pump Repair - Important Info 

It was interesting to me that you kept a pump from 2018. I have replaced these 5 times now at a steady interval of every 2 years. I would re-use the pump normally if possible but the trouble it takes me to get the pump out I just automatically put in a new one, at $40 a pump it is just insurance for me. But you did give me some good ideas. Since my RV was a rental, maybe there is sand in the tank since renters are less carful when filling the tank, and I need to do a better job of trying to flush it out. Excellent video by the way!

This is an excellent video which has really helped me replace my pump. Very well explained. Thank you 😀

I like your idea of the connection being OUT of the water. My guess is that is the main weak point. But just a guess.

The design of these toilets is faulty. The pump HAS to be replaced about every 2 years since it is under water. And the hole to get to the pump is made for VERY small hands. I cannot follow the instructions at all due to the size of my hands. This is always a very frustrating task for me to perform, and in 11 years, I have had to do this 5 times now. I am just about out of the white wire and will have to replace that soon too.
