    Not as quiet as expected

    This is a good pump and it does what it's supposed to. The install took about twenty minutes and I used the Shurflo quiet kit (flexible hoses between the pump and the hard plastic piping). As long as you don't mind a little noise, this pump delivers the pressure and flow you want. I had a problem with it not wanting to shut off until I found I had an air leak. Once fixed, no problem. Except the noise.

    I bought this pump to replace a shurflo 5.7 extreme series that would not prime and once it did would not shut off. Was able to use all existing fittings so installation was quick. I love the pump so far, great pressure, primes quickly no drawbacks that I can see.

    I replaced a 2088 shurflow , which this is a direct replacement for, in my camper. The pressure is better and the pulsating was gone. My wife loves it . Installation was just a matter of connecting the water lines and hooking up the electrical connections . The screw pattern and size is the same as my old pump .
