Hi,
We had a guy out to open the pool this year that said our multivalve was going to need to be replaced. It has gotten difficult to turn and is making a funny noise like plastic on rubber when I turn it.
I no longer trust our pool company...they seem to have lost all their good people. Is he correct that it will soon need to be replaced? Is there any maintenance I can perform?
thanks,
vp
Depending on the brand, it may be as simple as lubing the inner works gasket, called a "spider" because it looks like a spider's web. I had a similar problem a few years ago, split the unit, lubed the spider and VOILA!, just like new. It's the same lube you use on the o-rings for your connectors (if you use them). Every pool store sells it--silicone lube.Quote:

I find it hard to believe that any multivalve manufacturer does not make it serviceable. Who would buy it more than once when you can get a Hayward or something else which is rebuildable until the structure cracks!
Vp, Carl's got it right (go figure:eek: :) ) If you take it apart and have any questions, we'll talk you through what needs to be done. 90+ % of the time it's the 'spider' gasket a/k/a 'wagon wheel' that is the problem. Pop it open and tell us what you find and we'll help you get it working properly again:cool:
I know that sound....mine has made it in the past, too, and it ended up being the gasket. Somehow it got hung when the valve was turned and got twisted out of the place where it's seated. My spring was also rusted and needed to be replaced.

Ah, Waste, you type faster than me!!

Hey! Even a broken clock is right at least twice a day! :pQuote:

If it's not all the way down, the mechanism is still pressing on the gasket as you turn it, which pulls the gasket loose or twists it. The gasket needs to be secured in its place with a sealant, not a lube. I use Permatex blue RTV gasket maker from an auto parts store, with excellent results. I think the Permatex number at the bottom of the tube is 6. I'll check it when I'm at the pool later and then confirm. Also, when you service the gasket, it is 'this side up ' specific so be sure to put the same side down as when you found it.

Jan, you must only have 1 finger, 'cause I only use 2:DQuote:

We ran into this problem with our Hayward Multivalve. At first we took off all the screws and replaced tangled old 5-spoke gasket with a new one, but it didn't really make it much easier.
It appeared that the old valve wasn't allowing the mechanism inside to clear the gasket properly when the handle was compressed so we replaced the Valve Key, Cover and Handle Assembly part, (not the whole assembly) p/n SPX0710XBA17, and it was really easy to turn afterwards.
Just a note: We ran into a different problem afterwards. Each time we'd turn the handle to backwash and then return it to filter afterwards some water would continue to pump out the backwash hose. (First time this happened I had no idea until I saw the water level of the pool surprisingly low.)
We'd open the valve and check the gasket each time. Sometimes it looked fine, other times it needed to be reseated.
I found out by dealing with the Hayward tech support department that the gasket is supposed to be glue in on it's flat side to the bottom of the valve housing with a special adhesive. (3M Scotch-Grip Industrial Adhesive 4799)
I ordered it from the 3M store, since I couldn't find it locally, and it's been good since then.)
Good Luck -
