Replacing Hayward Multiport Valve

[saclevenger]

Woke up this morning to find my pool had leaked overnight about a half foot. After looking all around, I found the leak coming out from my backwash drain at the road. I have the Hayward Multiport Valve SP0714G11M. The handle is loose. It's really difficult to turn. After skimming parts online, it seems if I'm going to replace the spider gasket, o-rings, spring, etc. I might should just replace the whole unit. My problem is that I'm not finding the same model number. Any idea how I can figure out a comparable replacement? Gotta get it fixed asap. Definitely don't want to leave that pump idle this time of year in Florida.

Here's a pic of it too.

Maybe it's the "Vari-Flo XL Valve" that I need search for?

What is the filter model number?

Looks like the two choices for a sand top mount are SP0714T if you want a 1.5” valve or a SP071621 if you want a 2” valve.

Thank you, James. Actually just got it figured out a minute ago and the key/handle assemble ordered.

Got the new MPV. Lubed up the spider gasket and o-ring and installed it. But it is still leaking out of the backwash when in filter mode. As I installed the new unit, it went on perfectly. I turned on the pump. It spit out some air bubbles on the deep end of the pool but eventually primed. I turned it to backwash and the handle tension was instantly gone. It backwashed fine. I turned it over to rinse and that worked fine. Back to filter and it's working fine, but still leaking. I then turned everything back off and removed the MPV. As soon as I pulled it up, the spring created tension on the handle again. I noticed that the handle has proper tension as I pushed the MPV down until I got down to about 1/4" left. When I push the valve further down, the handle loses the tension. Could whatever be causing this also be causing the leak out of the backwash? So frustrating for a brand new assembly to do this.

I turned on the pump.............. I turned it to backwash and the handle tension was instantly gone.

Did you turn off the pump first?

 

[saclevenger]

Oh yeah. Pump is always off before turning the handle.

There may be a crack in the main body of the valve, then.
