Fit and quality was excellent for making repairs to my RV water pump. Repaired an older pump as a backup. The kit brought new life and function to a pump that I thought was done-for.

It’s a simple task installing the replacement pieces provided yet, once the task was completed, I was in much worse shape with leaks and a pump/motor that wouldn’t shut off. All o-rings are in place. When I had a partial disassembly, I noticed the new diaphragm leaks.I’ve gone in and out of this pump assembly trying to figure out how things got worse. When I put the old parts in, it works better than the new parts. I finally gave up and bought a whole new pump.
