We have been battling our Americana MPV for years, we have tried glue and no glue on the spider gasket and it doesn't seem to work. The valve has probably reached its lifespan. It needs a new spring I never found one I understand Hayward bought Americana. Each time after working on the valve water leaks between settings, for example filter to pool and some will leak out to backwash. How difficult is it to get a valve with the same orientation? Are they uniform? After removing the old valve do you use slip unions to join the PVC? I apologize if this is covered extensively in prior posts I am not the greatest at navigating with computers and tried a search and didn't come up with anything.
Thanks for any help
