Review on Thetford 70475 Impeller With Gasket by Marfel Fekete

It's not an easy task but wow we didn't enjoy how long our dump took so we went decided to finally replace it impeller. The old one didn't exist - only the plastic part remained inside - and a lot of hair on the metal air intake fins. difference between day and night. What used to take 45 minutes (we have huge tanks) now takes 5-10 minutes, it's like a water hose rushing out. I've compared the markings on the parts I've received and they match SHURFLO 9457100 100% - the price on Amazon is about the same between the two, but both seem to go on sale or sold out at different times so consider cross-buying if necessary. I'll add one of these as a fallback as I know how much of a difference it makes now. The manufacturer suggests a replacement after 2 years - I understand why - the entire impeller is made of relatively soft rubber - it wears out quickly in the environment it is in. Gray water nearby - you need to drain the chopper inlet and outlet hoses. Be careful with the pump nuts and bolts to avoid losing them. The kit I received included a large flat gasket but no external o-ring - I reused an existing one but it would be nice to have one to replace. Also. The rest of the R&R parts are solid parts that don't wear out.
