I have been reading reviews on Amazon when I was looking for a water pump for my teardrop. Sureflo, Flowjet, $15 or $100 all the reviews were the same, Best pump ever, junk do not buy. My last XXX pump lasted 35 years this one broke the first time I used it. It's whisper quite, sound like a F-35 taking off.
I didn't know what to get, so I bought a $17 one to try and it works well, and I'll get another for a backup. I used hose clamps and quick connects so a swap out should be easy. I have about 20 gallons though it now. It is loud and vibrates a lot but for $17 I'm happy with it so far.

I just noticed it is unavailable now, but there are other that look just like it in the same price range.
