Review on KOLERFLO Pressure Booster Automatic H15GR 15 by Steve Harris

Purchased to improve hot water flow in a two story home that had years of hard water build up in old galvanized pipes. Hopefully this buys me a few years before I'm ready to upgrade my install. Fairly easy to install, but the pressure switch output is from a 3/4" male connector at the pump outlet to a 1/2" female thread connection after the switch, and the brass fitting is a different thread pitch than the other standard. Brass connections. I eventually found some electroplated hardware that would fit a large chain hardware store, but it worked - with lots of Teflon tape. It's only been a few weeks, but I'm happy with his work. Not sure if it has built in speed control but it seems to work better with more water. The only reason this isn't a 5 star rating is a fitment issue, the noise is a bit louder than I expected and it hasn't been used for a very long time. If anything changes I will update the review.
