Eric Posted: 11:55 AM I have 3 questions please. My valve is in filter position and I have a closed valve on the waste pipe. Can a leaking spider gasket cause air suction when pump is closed? When my pump is off I hear air suction at the valve shaft. Can a leaking spider gasket be the cause of water leaking at the shaft, or can this only be caused by defective shaft o-rings?
I notice that the metal washers with the shaft spring come in a set of two. I opened my valve and could see only 1 metal washer, on top of the spring. Is this possible or should there always be another washer underneath the spring. My valve is SP071620T. Inyopools Posted: 12:53 PM Inyo Product Specialist Mike S. - I'm not sure what your question is.
Are you asking if the leak can be fixed by replacing the top Key Cover and Handle Assembly or if you have to replace the whole MPV? Let me start by saying there are three major replacement parts for the common Hayward MPVs: the whole Multiport Valve (MPV) itself; the Key, Cover, and Handle Assembly (KCHA) and the Key Assembly (KA) itself. The KCHA is the upper half of the MPV and the KA is the lower half of the KCHA. Most repairs are fixed by replacing only the KA. In your question, you mix replacement parts between the SP0714T MPV and the SP0710 MPV. For the SP0714T MPV, the KCHA is SPX0714BA and its KA is SPX0714CA. For the SP0710 MPV, the KCHA is SPX0710BA17 and the KA is SPX0710XD.
