I have a hayward sp714 valve. I am going to be replacing the spider gasket, but before doing so I want some information on whether there is any maintenance that should be done on a multiport valve, such as greasing anything, etc. The spider gasket is in place, but the valve is very difficult to rotate. I'm not sure whether the spring assembly is not lifting the plate properly and will be trying to check this later. Is there some type of cleaning or greasing that should be done around the white plastic under the handle(I think the hayward parts catalog lists this as a non-metallic bearing). Is there anything that needs to be done around the spring assembly? If so any tips on properly dismantling the handle/spring/plate assembly?
