I did a temporary set up on this pump and it works great. It is not as noisy as some I have had. This will go into an RV setup I am building and be perfect. I replaced the pump that was very similar to this one in my camper last year. I can't finish the job installing this because it is below freezing but am happy with the test I did so this seems to be a nice pump at a great price. I may update this review when it is summer again and I can not just test this but put it to use. So far so good. It does also come with Teflon tape, the fittings, and a strainer.

Had a similar pump go bad after a decade of use. A bit of research revealed this pump which has been working great. The pressure is consistent and works just as well as the factory original. Would recommend this pump if your old pump is in need of replacement.
