Excellent pump! Super easy to install. Increased pressure 40 psi so can run 5 baths all at same time. Maintains pressure at 60 psi. Very quite while running.

Grundfos scala2 easy to install. I'm on a well and I installed the pump after my water filter and softener. Please note that the pump works as one way valve therefore hot water tanks will now need an expansion tank.

Pump is very quiet. This is my third pump. Previous pumps each lasted about two years before they started leaking. First pump was replaced under warranty (just under 2 years old). Second pump was not (just over 2 years old).
