I don’t have any input on which pump to use, I would like to know what your impeller looks like and if it appears to have been changed before. I have about 110 k on mine and it shows no evidence of being changes.
Thanks

Many different brands you can use but most folks use a ShurFlo pump. I believe 3-4 gpm is average.

Are you asking about the Cummins water pump or the house 12v water pump?

Sorry, should have clarified that I’m talking about the house pump. Has a shurflo on it now. It’s weeping at the seam in the black housing. Haven’t taken it out to see if it’s fixable yet. Thought I’d replace it, then attempt repair on this one and keep as a spare.

Sureflow is the best bang for the buck. I always keep a spare onboard as no pump makes things pretty complicated

My mind went straight to the coolant pump on the engine.
Ironically I did just change the house pump and went with the Sure Flow.

Sureflo 4008-101-E65.

Just replaced ours. The old one would run for a second every so often. Couldn’t find any leaks. New one only runs when a faucet is open. As far as I’m concerned, that confirms no leak. Kept the old one as a spare.

Shurflo is one of the most popular with Jabsco probably not far behind.

Ease of installation is always on my mind. If a new pump with the same footprint and plumbing connections can be found it can save a lot of grief. Difficulty is manufacturers modify design on their products and finding a plug and play replacement for an older pump without modifying RV plumbing connections is not always possible.

Oh, most house pumps do not have an impeller and are diaphragm driven. The advantage is they can be run dry without damage.

In our case, the pump was a direct replacement. I simply had to crimp on the appropriate terminals to match what was on the existing wires. The old, now spare, pump is dated 2012.

Shurflo are really just a throw away pump, have to replace about every 5 years or so, sad to say.

Shurflo, what a misnomer of a name.
