I have a pinhole leak on the bottom of my multiport valve, Hayward SP0715. Very small stream of water steadily leaks from bottom, front of valve. Was likely was installed in early 90s. Also have an old stainless steel PacFab PF-50 sand filter installed at the same time.
My question is, should I replace the sand filter at the same time as the valve due to it's vintage? As far as I know the sand filter works OK with limited time I've been able to run it (a few hours) this spring. If I do decide to replace, I know I want to go sand or DE. Any suggestions or should I hold off on replacing filter too?
