We just replaced our factory installed water pump with a SHURflo Extreme Series Smart Sensor 5.7
It’s a variable speed pump meaning it increases its rpm's as demand increases where the original pump used a pressure sensor which is what causes the pulsating you typically hear with a pump of this design. We can now have all the faucets on without any decrease in water flow. It a lot quieter and the installation only took about 15 minutes.

This was a great addition to our 5thwheel and should be considered a must have item. The difference is night & day.
