Hi,

I want to replace my old, and getting hard to move, plunger style filter valve with a multiport valve with more than just a backwash function. I have the Pentair DE FNS Plus 60 filter, looking at the Pentair site I can see these two:

Pentair 261142 2-Inch HiFlow Valve

or
Pentair 261152 2-Inch Threaded Multiport Valve


Does anyone have any views on either of them, is there another model/brand that I should be considering?

The current plumbing is not an issue as I'm going to redo the whole pad, as I have the FNS 60, I'm thinking the HiFlow would be better, but how is the reliability? I'm seeing some not so great reviews on Amazon (whatever thats worth)
 
What fun! You get the play with puzzle pieces aka pvc pipe LOL

I don't know which one is best but know someone who will. I will put in a call to them. If anyone else knows which one they should get jump on in!

Thanks yes, I’m going to make a mock up in my garage and try different layouts until I have one I’m happy with :) should be easy enough only have 4 main lines
 
When I rebuilt my OLD Pac-Fab sand filter, I went with the 2" hi-flow valve because, well, it was "better" that the standard flow but in reality I have no idea how much better it is over the "low" flow valve. As I recall, the price difference was minimal at the time so the choice for me was easy.

Everything else being equal, the one thing that would swing me towards the hi-flow valve is the glue fittings over the threaded fittings. It's just a few less places for leaks to occur and I used unions at all connections so I can still remove all parts for service if needed.

If you are using unions, is that not more joints to leak? The slip that’s glued and the union? Or is the union joint far better than the threaded end?

Thanks for the info!
 
A properly glued slip joint will never leak and the unions have o-rings for sealing surfaces which are far less likely to leak than pipe threads. In addition, unions can be "adjusted" after assembly if needed. Threaded connections normally cannot be tightened once the rest of the piping has been permanently assembled.
