Is the 263064 the appropriate Backwash unit for the Pentair 180009 filter?

BEST ANSWER: I had never installed a backwash with a filter but mine worked perfectly well when one is mated with the other. It's been installed for about 2 years now with absolutely no trouble at all.

Pentair Backwash Valve
Following the instructions made the installation of the backwash valve really very easy. I had never installed one before and after the installation, the backwash valve worked just as described. It functioned perfect during the first use with no problems.

Pentair Backwash Valve for DE Filter - 2" PVC with Unions
I had my filter and backwash valve installed professionally, although this was a personal option and not a requirement. It is easy to use, and is a great improvement over a previous older model backwash valve.

Pentair FNS 48 SF filter and backwash valve.
Pentair FNS 48 sf filter and backwash valve made my pool sparkle. The backwash valve install took some time but the filter was fairly simple. Great products.

Works well
If you can do basic sprinkler system repairs and/or installation you can definitely do this. You have to be careful not to force the valve to turn or it will break though.

Great price
This backwash valve has worked perfect with my Hayward filter. It's very easy to use and a great price I found on Google.
