I have to replace one of the valve's in my above ground pool's plumbing and wanted to get your input on how I should do it as I am not much of a handyman but I can definitely follow detailed directions! The valve was frozen shut so I tapped it with a rubber mallet and both ears broke off. When I finally did get it to move it is not working. I'm thinking that I will have to cut the piping off with a hacksaw on both sides of it. Besides the valve what else will I need? What type glue, fittings, etc.? Any ideas of suggestions would be very much appreciated. Don't assume I know anything and please give me all the necessary steps! Thank you! The first three pics are of the valve I need to replace. The 4th is the type valve I am talking about.
