I found this at the bottom of my pool:
Looks like a 8" man drain.
The white washer on the right was at the bottom of it. I guess it was blocking all the suction from the pump.
I've tested by plugging the skimmer and starting the WhisperFlo pump and the water at the bottom of the main drain started to get sucked. So I guess they are connected.
I've not found a 3-way valve that would allow me to regulate the flows from the skimmer vs the main drain. There is only one tube that comes out of the ground and goes directly to the WhisperFlo pump.
How does regulate how much does each side (main drain vs skimmer) takes in?
Don't I need a cover on that drain? Which cover model would you recommend?
Thanks for your help
