I have a Hayward SP710 multiport valve that I thought had a bad spider gasket. After a bit of reading I'm not so sure. Apparently, the sign that the gasket is bad is leakage into the backwash hose. My problem is that the handle won't turn. It had been getting harder to turn recently (I have to drain my pool frequently due to LOTS of rain) and now it won't budge. Is there anything that might need lubricant/repair/replacement that would cause this problem? Do I need to replace the whole key cover and handle assembly? (I hope not; pretty pricey!)
Thanks, in advance, for any assistance.
