Multi Port Valve Gasket

[aquarium]

I recently replaced the spider gasket in a Baker-Hydro/Hayward multiport. I just used silicone lubricant to seat it in the grooves, so I expect it to eventually come loose during a switching operation. I wiggle the handle a little before changing direction so maybe it won't stick to the diverter, but this does seem to be a lame contraption. Glueing it in place just makes it -really- hard to replace. I might use a few small dabs of silicone -sealant- in strategic places to hold it in place when it fails again.

Oh My Gosh....silicone seal? You're opening a can of worms. Just joking, you may find out that some here say you don't even need to stick it in place. Last fix on mine I used SS too. Only I cleaned out the channels, squished a liberal amount of seal in them, placed the gasket, then put a wax coated plastic sheet over the gasket...wax paper will work fine I now know, then bolted the thing together and let the spring force the upper part onto the gasket. Let it cure for a day. The wax paper keeps the silicone from sticking to the top part and silicone seal won't stick to wax paper. Use a box cutter blade or an X-Acto knife to trim off excess silicone and it's been holding just fine.

PS: With silicone seal, duct tape, and PVC you can do just about anything.
