Backwash pipe

[WHINGER]

Hi.My name is John,i have just joined today to see if i can get any help.
The problem i have, is when i put the pool selector valve on filter mode ,the pump is working ok ,but i have noticed water coming out out of the waste pipe,that is connected to the water butt that i use for backwashing the pool,it does not come out when recycle mode is used .
the pool is a astral liner one i have had it 8yrs and had no problems till now.
I hope someone can help me soon.

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 $$.
