Review on KOLERFLO Pressure Booster Automatic H15GR 15 by Mark Tarnowski

This booster pump was installed in series after my shallow well pump. A shallow well pump produces about 40-50 psi indoors. I've had printing issues on the 2nd floor for a while so thought I'd give it a try. As you can see from the photos, installation was pretty easy. I installed a Shark Bite check valve just before the booster pump. You can see on the gauges I had about a 20 psi pressure rise. This pump isn't as loud as some have said in their reviews - it's quieter than my shallow well pump. So far very happy with the quality and performance of this small booster pump. Update: 03/17/21 This pump is still working as intended. A note to potential buyers: you don't need GHT adapters for home use. GHT for garden hose. The fittings on both ends are 1/2" NPT threads and connect to the 1/2" NPT water pipe threads. Also, some say the pressure switch has I and II, denoting I for constant on and II for pressure drop detection. My pump was marked MOVE-STOP-AUTO. I am very happy with this pump. If anything changes I will post an update.
