I have a Pentair multiport that has a handle that is hard to turn and the handle doesn't spring back into position after turning and releasing it. In other words it seems "limp" It is also very rusty probably do to some years when the water wasn't handled properly. I replaced the spider gasket. So my question is: is this thing salvageable?
Can I rebuild it successfully? The top of the gray mechanism where the handle rests almost looks like part of the top of it is broken off. Please see pic. EDIT: I just googled the valve diverter and it appears they are all made that way on top so it is OK. Also the little white washer is cracked that sits under the handle. My valve says: Valve model: SM20-2 and Valve Assembly model:SM2-pp2.
I also noticed that there was no washer between the spring and the bottom side of the multiport top. When operating the lever it always made a screaching noise when turning. I wonder if this is why?
