The spider gasket did not seat properly!
Take it apart and try again.
get the inside of the valve body completely dry, and make sure the grooves in which the gasket seats, are completely cleaned and free of any old sealant or gasket material.
Then apply a little bit of Silicone sealant, not much, into that groove. Then reassemble. Do NOT turn pump on for at least 8 hours to provide time for the silicone to cure, then try it.
Hopefully this helps you.
Good Luck.

Either the gasket 'groove' had debris in it and needs to be cleaned, the gasket rolled out again, or there is a crack in the area the gasket sits allowing the bypass.

Be sure it is not plumbed backwards and be sure you got a sand valve as a DE plumbs the other way.

If you remove the top of the valve you will see a spider gasket that has pulled out of place. remove this and clean and dry throughly. Add a small amount of silicone sealer to the bottom of a new one and install in groves then replace top of valve and let sit for a couple of hours. That should fix. If not you will need to replace the top half of the valve also.

SOURCE: We have a hayward sand filter and have replaced

There is more than one version of these valves. The model like sp072 has a 5 spoke spider gasket that has one opening larger than the rest. Be sure it is in position so that the large opening lines up with the large opening in the valve. If it's a SP0714 then the rubber is molded on the valve itself and would have to be replaced together. In either case, the seal is provided by the spring pressure forcing the valve faces together. That is why you should depress the handle, and only turn the valve while it's depressed, and the pump is off. After you turn to the selected location, then you release handle, and the valve surfaces should spring back together. Be sure the lever has spring tension on it in case you left it out while working on it) You can download complete manuals from www.haywardnet.com Good luck!

The spider gasket in the valve needs to be replaced. It is underneath the handle assembly.

I have a brand new filter..im leaking lots of water from my backwash when on my filter setting


Your multiport spider gasket is bad. Just replace it by removing the top assembly. Remove the 6 phillips screws on the valve cover and the whole assembly will come off. This is easiest done when the valve is first put on the "Winter" position

When I was moving the handle to backwash I couldn't hardly move it and after I moved it back to filtration position the water wouldn't stop running through the drain hose.


This problem occurs when the "spider" gasket inside the multiport valve fails. This repair can be done by a homeowner but requires a few things. 2 c-clamps, the new spider gasket, and chlorine safe adhesive/caulk to seat the gasket.

I dont know what model multi-port valve you have as there are 3 model that fit on this filter. Here is the link to haywards manual site where you can find a manual on your filter, and your valve that will list instructions and part numbers.

My pump is on filter but is draining the water out please help


The water Has to be going out the 'backwash' or 'waste' line.Either that or you have a leak in the plumbing. If the backwash/waste valve is set in the 'filter' position and there is still water escaping through the backwash/waste line, it means that the o-ring or spider gasket needs to be replaced or re-seated. If it is a multi-port valve (one that you spin to select the setting as opposed to a 'push/pull valve) you can try shutting off the pump; do a complete turn, 360 degrees, from the 'filter' setting all the way back to the 'filter' setting. This sometimes helps the spider gasket re-seat

My filter and pump will not retain the prime after turning off. Its a pantera sand filter. I can hear an air hissing sound coming from the multi valve port


Either you have a bad spider gasket inside the multiport valve or a bad threaded fitting going into it. Check for leaks around the multiport and backwash line. You'll have to take apart the multiport valve to make sure the spider gasket is not damaged or out of place. Make sure to install the multiport valve in the same position. You can get a replacement gasket at most pool supply stores or online.

What do i do with the waste line port on the multiport valve on a hayward filter. do i attach a fitting to stop air


No. That port is there for when you backwash or pump to waste. You normally put a hose adapter there that allows for a collapsable backwash line to be attached when ready to backwash the filter. If it is leaking water there when the valve is set to something other than waste or backwash yuou need to replace the internal gasket in the valve.
