Hydrolevel VXT alternative install
In looking at the install picture for the VXT, they suggest using three isolation valves. One of the valves is placed on input side of the VXT and the other is on the outlet side of the VXT. Because of the location of both the H2O supply and subsequent feed into the wet return, my layout will look nicer if I change it from the suggested method.
My question is this: do I need the isolation valve on the output side of the VXT or will it be just fine without it?
Note: I just realized that, in my drawing, one of my valves is labeled wrong. The one feeding the VXT should be labeled as 'isolation valve'.
