I just moved into a house with a green pool. The previous owner left no information about they system. I know it is a Hayward Sand Filter with a Hayward Control Valve. Every time I try to run the filter, water comes out of the the waste line, no matter which setting the control valve is on. I need ideas before I dump more money into this house it is already costing me a small fortune to fix!
Thank You
Hi, and welcome to the forum!!
I'm sure the equipment experts will chime in here shortly, but my first suggestion would be to take the faceplate off the multiport and see if the inside is intact, or possibly cracked, which would let water through as if it were set to "waste", no matter where the setting.

Here's a link Pooldoc posted to the inside of the multiport with the gasket taken off. The plastic channels you see there are what I was referring to...http://www.poolforum.com/pf2/showthr...gasket-install
I took the face flate off and it seems the spider gasket may need to be replaced, it seems stretched out and not sitting properly in the "track". Also, in that top picture it seems that one of the openings has a plastic piece covering it, i do not recall seeing that, i'll have to look again. Is it possible that the gasket is the problem?
Yep. A failed spider gasket can let water go everywhere.

PS. Replacing a spider gasket successfully is tricky, and none of the aftermarket glues to hold the gasket in place work like the OEM stuff. Consider replacing the valve if that's not too hard. If you clean the channel the gasket rests in very carefully, clear silicone will probably hold the gasket in place for a season. Do NOT use too much. If "Waste" sees this thread, he may have a better suggestion.
There does not seem to be anything actually trying to hold the spider in place. Or should I say no residue of what should be holding it in place. So, I should just replace the whole valve? Is that hard? My husband is a truck driver and rarely home so I tend to tackle this stuff on my own!!!
So it would be best to replace the whole control valve? It may or may not be important, but there seems to be no trace of any type of silicone or anything where the spider gasket is supposed to sit. Also, is it hard to replace the control valve? My husband is a truck driver and I usually try to tackle these types of projects myself. And if I were to try to just do the gasket, is it someting I can purchase anywhere or is it a pool store type item?
Thank You
I usually get my replacement gaskets from the pool store, haven't seen them anywhere else. I usually end up going through a new gasket each season. I don't think replacing the control valve is a big deal--the one time we've replaced ours, it came in one piece and hubby installed it--and he's not at ALL mechanically inclined. :) So I think it should be pretty easy....

Thank you so much for the help! I'll try the gasket first and then go from there. I'm sure I will be back to try to make the transformation from green to useable! This is a great forum with a ton of good advice!
Welcome to the Forum!
Glad you were able to find good advice to help you. As long as you're trying the gasket first, try it without gluing or siliconing it down Al (Poconos) and I had a discussion about this a few years ago and I still say I never had a problem not securing the gasket in place, as long as the channels it sits in are in good shape. If you glue it in and the channels are shot, you'll ~ wreck the gasket trying to peel it back out. If no glue doesn't solve the problem, then by all means put some glue or silicon on it and try again. If that still doesn't work, it's time for a new multiport valve. [I don't seem to be able to get the advanced search function to work for me...???]
If you don't remember a double section being blocked off, you may have the older 6- spoke gasket (as opposed to the newer 5 spoke gaskets) - double check before getting the new one, as the part # you're looking for is the same for both the 5 and 6 spoke gasket. The part # is SPX710D for multiports with 1 1/2" piping and SPX715D for multiports with 2" piping.
One last thing, when you put the multi back together you'll notice that there is a flat (vertically) side to one of the 1/2 moon protrusions where the screws go on both the body of the valve and the top plate - be sure they match up! so that the valve is oriented properly.
Please let us know how things work out for you and feel free to ask any more questions you have.
Okay... I got the new gasket in, with no glue Waste : ), and now all is working well. I have the filter running right now, for several hours already. So, what is my next step? I read the BBB method and I thought I saw that it says for salt pools, which mine is not. Should I go for the BBB method?
