Thanks. So, Neither of you recommend using the B Adapters? I am waiting for the B adapters and the plunger valves to come in the mail( purchased separately). I was originally under the impression that the only conversion parts needed were the b adapters, then was told I needed the plunger valves also to connect to the b adaptors. I'm still trying to figure out the purpose of the b adapter, looking at pics it looks like one end slides into the rubber casing protruding from pool (1 1/4") and the other side connects to 1 1/2" hose? But what you are both saying is the B adapters are not needed, I can just connect the plunger valves instead (but would have to cut a bigger hole in pool) my pump didn't come with any extra fiitting or adapters, guess the seller was a bit frugal.
