I just opened my pool and learned that my polaris pb4 booster pump is leaking at both the supply port and return port. There appears to be some sort of rubber in there that looks like it has dry rotted? I am not sure how to correct this. Do I need to cut the pipes and re-glue everything? Are they threaded on? If so I assume I would need to cut the top of the pipe and attach a new connector. Any advice is much appreciated! Here are a few pics.
