Hello! I am so glad to have found this forum! I like troubleshooting, but I am stumped! I have a 20 year old inground pool with spa, using a Hayward cartridge filter, and a Navigator pool cleaner. Everything (pool skimmer, pool cleaner, waterfall, pump pressure is good) all seem to work independently, but when they are ALL on, the skimmer does not seem to work. I think there may be a blockage somewhere in the skimmer line. The baskets are clear, at the pool and at the pump. I saw another youtube video showing how you can take off the skimmer valve, and check at the 90 degree pipe angle there for blockages. I may do that next, but was wondering if you had any other suggestions as to why the skimmer will not run at the same time as the other pieces.
Thank you for any advice.
