I bought a foreclosure and the pool was built in 2006. Knowing very little about the history of the pool I am having my filter deep cleaned and sand replaced in a few weeks. I know you don't need the sand replaced but they are offering a special and it comes with sand replacement.
I also am also having the spider gasket replaced. They suggested replacing all the parts in the multi port valve. They said it would be under a $100. Is this a normal part of routine maintenance? Anything else I should have them do?
