Hello, I have a cracked Jandy diverter valve that needs to be replaced, but the plumbing is tight and connected at the fittings. I'm looking for suggestions on how to fix it. I'm thinking it might be easier to remove all 3 valves, but I'm not sure where to make the cuts so I don't have to drain the pool. Will draining the pool be required? I really appreciate any help you can provide.
