Good Day Eduard. Given the model of the valve and the number for the gasket, those are a correct match. As for putting it in wrong, that is indeed a possibility. This is a link to How to Replace a Spider Gasket on a Multiport Valve from our site. Please take a look, perhaps something was missed.

Ordered a diverted valve gasket (had to buy whole assembly) for what Ithought was a Hayward filter. Turns out it has a Praher Valve Assembly. Received the wrong part. Only need to replace gasket. You show a 2" and a 1 1/2" 5 port gasket. What are the measurements, the pipe or the size of the gasket?

Hi Carl, I would recommend that you replace the Top Valve Assy and the Diverter Gasket.

why do I see several gaskets with part number 271148 but various outer dimensions (7", 6.5', 6.75")? I have a pentair valve model sm-20-2, valve assy SM2-PP2. Which is the right valve?

Hi Joe, We have the dimensions listed on the Product Dimension image. The SM2-PP2 will replace the SM20-2 for DE filters.

Removed valve cover. Used a chisel and screw driver to remove and clean all remnants of old gasket. Added waterproof silicone adhesive and installed new spider gasket. Allowed two hours to cure adhesive and fired up the pump. All good!

After backwashing my sand filter, I noticed I still had water going out my waste drain. I could wiggle the multiport valve handle a little bit and it seemed to sit correctly, but I didn't want a complicated process just to get it to function properly. I took apart the multiport head and the gasket had rolled over and out of alignment. A new gasket is no big deal, so I ordered several of these to have spares on hand after installing a new one. I love that these gaskets and nice and square edged, I looked at several other that were more rounded but that is what caused the problem in the first place. Nothing lasts forever, but with some magic lube this one seems like it will go longer than most.

Our Jacuzzi sand filter is about 15 years old. The backwash (waste) was leaking so we checked the spider gasket (star gasket).
Check gasket in the key assembly on top of the pool sand filter:
*power off
*release air tight seal(I opened the pump skimmer basket to release air pressure.)
*unscrew key assembly
*spider gasket is set inside, it seals the key assembly to the filter.
*the worn gasket was so old it looked like tar. It did not come out in one piece. It took an hour of scraping the channel with a screw driver and pliers to clean the channel to seat a new gasket.
*our local pool supply gave us a standard gasket and it was too small.
*we ordered from INYOpools because they displayed the actual measurements, so we knew we had the right part.
*no local *professionals* were willing to replace the gasket (too much labor cleaning the channel and more profit ordering a new complete sand filter).
*so for $13, our pool is up and running perfectly with a simple spider gasket

VERY GOOD AND RELIABLE PARTS AND VERY FAST SERVICE GETTING YOUR POOL PARTS. HOWEVER IF YOU HAVE TO RETURN A PART YOU HAVE TO CALL EVERY 30 DAYS TO GET THE REYURN CREDIT AS I DID ON PO226670 FOUR MONTHS AGO AND I STILL DO NOT HAVE MY CREDIT. IT IS JUST A $50 CREDIT, BUT HAY, $50 IS $50. SO I WILL CONTINUE TO CALL. I WAS JUST TOLD AFTER 5 MONTHS THAT THEY WERE SENDING ME CHECH IN 5-7 DAYS. SO, I WILL WAIT AND SEE. THANKS

I was a little concerned that removing the old gasket would be an issue. I used a flat bladed screw driver of the correct width and the old gasket came away with minimal effort. I glued the new gasket at critical points and reassembled the valve. I left the valve in a closed position for several hours before changing to filter and starting the pump. That was a year ago, no air leaks and the valve works perfectly.

Was happy to be able to buy this economically and be able to replace the gasket in my Sta-rite spider valve that had rotted out from time and use.

This was an exact fit and completely solved our issue of a water leak. We thought we had a crack and all it was is this original gasket was dried out and cracked which allowed water to bypass the selected position and pump water out our drain hose and we didn’t even know bc it is hard plumbed 150 yards downhill from our pump. Thanks INYo!
