I was having water leaking out the backwash hose when the valve was set to filter. Not knowing what the issue was i took the 6 - 8 bolts out of the top to have a look and even removed the pin, handle and spring. I then noticed that my "spider" gasket looked worn. I put everything back together and stored for the winter. This past weekend i stopped by my pool store and bought a new spider gasket and lube, went home and replaced the gasket. However when i bolted the assembly on it seems to compress the spring (the handle is completely loose), as if there is no room inside for the spring and valve to lift and turn. There is still water coming from the backwash. Could i have put something back together wrong or are some gaskets thicker than others? As i loosen the bolts the handle seems to go back into place, very confused right now, please help. I need to know whether to buy another multi-valve unit or if mine is fixable. Is it possible that i put the spring and assembly on wrong.
Also if i do need to buy a new one are they universal? i currently have a proline sand filter but the multi-valve does not appear to have a model number that i can tell.
