Customer Reviews

Worked great!

Installed in July 09 and have been using it for just over a year 1/2 with lots of contentment. My residential home water pressure was over 100 psi which visibly stretched/damaged garden hoses, and water would blast water out of sink faucets. This brought it down great, adjustment was easy, and it striked me as well made - not that i'm a professional that'd know good from bad. Had to take it apart and reassemble once because of an odd vibration noise developed, but I didn't actually fix anything... nor did I find any blockage. I blame the gremlins.
