Hello Newbie to the site. I have a pool/spa plumbing problem that I can't figure out. Simple plumbing system with caretaker 99 floor care. One valve for directing suction from spa or pool main and one valve for directing discharge to caretaker 99 or spa jets. Here's the problem: my system has a vent line that come up next to the caretaker distributor and has started pouring water out at a fairly rapid rate when using the care taker. If I shift the discharge to the spa jet -- it will stop. The vent is about 12 inches above ground and has a 180 degree "U" on top. I have searched the internet for a plumbing guide for this system, but none show a vent. Any ideas? Thanks
