Bypass Valve
March 21, 2021|Joe76, Illinois

Easy to install, took a couple of hours. Did learn from local hardware store to use plumbers grease to grease O rings. Products suggested in instructions will deteriorate O rings over time.

Easy to install if you have flex pipes.
April 28, 2018|Merlin705, Lv

Was easy enough to install. Unscrew 2 flex pipes and take off 2 clips. Reverse to install. Beware that this part had the intake and outflow pipe threads on the bypass valve. The one I replaced had push in and clamp adapters. So beware if you dont have flexable pipes, as the thread on fittings will be at a differant height.

As described, however, I think the item cost too m
February 28, 2018|Dave W, Undisclosed

If, like me, are replacing this item from a fully installed position, it takes at least 1 hour. This is to insure all gaskets and "O" rings are replace, or at least it top condition for long lasting service.........
