Modifying Jandy 3-way valves

Posted by kitamiman (My Page) on

As received, a Jandy three-way valve gives one the option to open/close two out of three ports. By unscrewing the top, repositioning the 'inlet' marked on the cover to the back of the valve (where there is no port), and replacing the cover you now have the option to open/close three out of three ports.

Is this OK? Advisable? In my case, this is a three way Jandy valve located shortly before Intelliflo pump intake; by making the third port closable I can not only pull water from either of the two ports, but also close the third port (pump intake) to isolate the pump for cleaning etc. Is this OK? All help much appreciated...

Not really. You run the possibility of dead heading a port. In other words, you can close a port that is going to restrict flow. If you want that 100% closure like a ball valve in front of the pump for isolations, it's real easy. Plumb as normal with the suction in the middle and if and when you want to close off the pump port, take out the thumb screw on the Jandy handle, lift the handle slightly on the stem so it clears the stops on the cap and turn it to the pump. This will close the port.
