So, I need to replace my multiport valve. It is a Hayward 'VARI-FLO' Model Number SP71. My DE Filter is a Nautilus 48 sq ft, it is old and I cannot read the model number. I think it is an 'FNS' style???
The reason I have to replace the valve is that a piece of male threaded PVC pipe broke off inside it. I tried to remove it... But I determined that it was GLUED in! Anyway, now it has to be replaced.
I went to Leslie's and they recommended the Pentair 261142. I had my valve and plumbing with me at the store and it will definitely fit with my DE Filter connections. I want to make sure it is the correct valve for my setup. Firstly, this valve is for 2 inch plumbing but my old valve was for 1.5 inch plumbing. He said I can just use reducers (adapters) to install it.
My filter pump is a Pentair WhisperFlo WFDS-24. The old multiport valve would make a lot of noise when I ran the Pentair filter pump on Hi Speed. I assume I was exceeding its flow rating.
Here is a picture of the old valve installed (except the plumbing from the filter pump to the valve is broken off).
Here is my setup now with the old valve removed. (Note that my Polaris booster pump has been removed - I am in the process of replacing it.)
The concrete pad that all of this equipment is sitting on has just about had it. It is crumbling in multiple places. I figure while I have it all ripped apart I might as well replace it. Has anyone just used pavers from home depot?
