My multiport valve (probably as Pentair SM10-2D.E., but the label has long since fell off) is leaking to waste a bit. Reading on the forums I saw that replacing the spider gasket is fairly simple.
I removed the six bolts holding the valve together without too much trouble. Getting the halves apart was a bit of effort -- it looks like I need to replace the cover o-ring as well. The spider gasket is visible and half black-half white. It looks like part has horribly bleached and I'm not surprised it's leaking.
The problem is I can't get the old gasket out. It is firmly stuck into the valve body. I can lift up a few small sections with great effort, but the majority of it won't budge. I'm pulling so hard, I'm afraid I'm going to rip it into pieces. (I'd really like the gasket whole to measure for a new one.)
Is there a trick to getting these gaskets out in one piece?
