Had a 13 year old booster pump for Legend type cleaner not making any pressure on opening this year. Figured time to replace. Purchased a new hayward booster to replace old A.O. Smith. Hooked up asit was in prior setup ex slight fitting changes. Turns on, seems fine but cleaner still not moving. Put hand over hose opening on side of pool and no real pressure increase over minor flow that goes through connection all the time.
So what could cause this? I assume not a major pipe leak as I have not been losing water. Coincidence that this was the same issue with old pump and something is wrong with the hayward? Any ideas or diagnostic steps?
Thx
