Multi Port Valve Gasket

[elsie]

A couple of years ago I, too, had leaking through the port discharge, assuming I understand that to be the port to which is attached the waste hose? If so, a guy I was then using for technical problems explained to me an easier fix. Of course, then being new to the pool scene, and not being at all a technical person, I have no idea why it was easier, but it may lend some credence to your issue. By the way, I also have a Hayward multiport.

What he did was install--and I don't know the technical name for it--a handle and ball assembly on that discharge port just a few inches from the multiport (before the waste hose attaches) which, when closed, stops the leak. When I need to backwash or waste, I then turn the handle and the assembly opens and I can do what I need to do, and then I close it again.

Elsie,
He just put a ball valve in the waste line to block that off. You have to manually throw it to block flow through the waste line. I did the same thing. For a long time I had some leakage into the waste line so that is the easy fix...put in a ball valve. Lately when I figured the best way to install a spider gasket, the leak to waste problem is resolved.

I was using a rubber plug in the discharge port but I like the idea of
Installing a ball valve. Seems like a simple solution
Thank You All!

You mean I actually contributed something here, ignorance of technical terms notwithstanding? Amazing!

You can pick up a ball valve up the street at Lowes. Fairly inexpensive.

Not so sure but at least a year ago the ball valves were significantly cheaper at Lowes comared to Home Depot. Same exact valves. From everything I've read on the forum over the years the blasted spider gasket in any manufacturers valve is a constant source of problems. The simple ball valve in the waste line is a cheap and easy fix. I went a little further because my waste line runs about 150' slightly underground to a stream and downhill about 10'. I added a check valve that vents to air so when I am backwashing and kill the pump the rushing and siphoning water simply bleeds air through the check valve so water flow from the filter is eliminated. The 150' of line simply drains out.

I recently replaced the spider gasket in a Baker-Hydro/Hayward multiport. I just used silicone lubricant to seat it in the grooves, so I expect it to eventually come loose during a switching operation. I wiggle the handle a little before changing direction so maybe it won't stick to the diverter, but this does seem to be a lame contraption. Glueing it in place just makes it -really- hard to replace. I might use a few small dabs of silicone -sealant- in strategic places to hold it in place when it fails again.
