    Pentair Multivalve 27-2120 Leaking

    Hi all,

    My multi-valve is leaking and after some searching here I believe I need to replace the spider gasket/seal diverter. I've looked on several parts suppliers but I haven't been able to confirm whether or not the gaskets online will fit the model valve that I have. It is a 2" Pentair 27-2120 (pic attached). I've found some gaskets online with part numbers such as 272409 and 271148 but the descriptions don't mention that they will fit my model 27-2120.

    Has anyone else replaced the gasket on this model? If so, can you please offer me some guidance as to which part I should order?

    Thanks!



    Jim

    Welcome to TFP.

    272120 is the part number for the label. Not the valve. The valve part number is 261142

    Part number 272409 is the spider gasket you want.

    Using a valve in backflow mode all the time

    Hey guys! First post here...google sent me

    Funny...I looked at the label and assumed the exact same thing!!! Who would have ever thought the label has it's own model number!

    Anyways I have the same valve apparently...and it's hooked up to a Nautilus NSS-48 DE filter.

    Now...this filter has seen better days...the stainless side wall on the bottom is cracked on both sides.

    SO...I got a replacement...I got a Pentair QUAD D.E. Cartridge Style Filter that I'm really excited about.

    Opened up the manual to figure out how to install it and BLAMO "The Pentair Quad D.E. Filter has a different flow pattern than ALL other blah blah blah"

    Bottom line is there are a few options.... 261055, 261173, 261050, 261165, 263034

    NOW...back to the OP's post...since my inlet on my current filter is on the bottom...and my new inlet is on top...couldn't I just use the same valve and put it in "backwash" position instead of filter position and rotate the sticker around and save myself $150!?

    TIA for your help
