Hi, John,

It sounds like the spider gasket inside the multi-port valve is mis-aligned or damaged. You can find a lot of folks to help you replace that at http://www.troublefreepool.com if you don't get someone to help you here.

I have never replaced mine so I am not the best resource for instructions.

Hi John,

I agree with the above poster, this definitely sounds like a damaged spider gasket. If you give us the multiport model number and make, we can give you a price on the replacement spider gasket.

The Astral spider gasket is particularly difficult to replace because it is glued into its niche during manufacture. It can take us upwards of an hour to gouge and scrape the old gasket out without damaging the thin walls (~1mm) of the niche.

If the water flow is minor and the multiport valve is Astral, I would suggest adding a regular valve on the waste pipe to prevent water loss. It is our preferred solution as it poses no risk to the multiport valve. A damaged niche in the multiport valve necessitates its replacement which costs $$.
