Recently bought the house and trying to use BBB and understand the flow and parts. I already replaced a check valve, but I want to understand more. There are some labels on the equipment and I've recreated those labels in the picture.
I suspect my pool has a small leak as my auto fill stays on 24/7. Which valve in this system should I check first if I suspect such a leak? I already replaced check valve #9 and that fixed spa draining into pool.
What is this Del Ozone system (parts #14, 15, 16) and how does it integrate with the BBB method?
Should I replace part #15 annually?
