I would like to replace the old valves which are feeding my pool pump but there is not much space to work with. I currently have three simple 2 port valves...one controlling skimmer, one for main drain and one for vac line. I usually have the skimmer line all the way open and the main drain partially open, unless vacuuming where they are both closed and the vacuum port is fully open.
I was looking at the Jandy Neverlube valves as a possible alternative and had a question about the three-way valve, model 4715 to see if it could replace the two 2-port valves coming from main drain and vacuum. Does anyone know if this valve allows one port to be partially open (for main drain) while the other is totally closed (vacuum)?
