Have this cheapo pump for a 300 gallon rain barrel, which has to be winterized. I have drained and taken inside and also taken inside with it still primed. In both cases it is locked up in the spring from rust. Once I manually break the rust lock it runs fine, but I have had to replace this pump pretty regularly as the bearings just fail. Would propylene glycol RV fluid or some other kind of lubricant help extend the life of this pump during the winter months while sitting in the basement?

Thanks, Tom

That may help, But how are you going to keep it in the pump ?

Just plugging the In and Out may work also.

Good Luck.

It has a foot valve so was going to basically prime it with RV fluid...

A foot valve stays closed under pressure, It may slowly leak out, with no pressure to keep it closed.

Good Luck.

This is awkward, but...
