Returns Not Working

[JamesW]

I’ve never touched it but maybe the people who closed the pool did for some reason.

They probably blew out the lines and closed the valve.

In the meantime, is there any harm in running the pump/filter with only 2 working returns?

No problem.

I think that the red circled ball valve is closed.

You can try opening it to see what happens.

Maybe it is closed for a reason?

Maybe the lines leak?

Note: The Hayward Dial-A-Flo Valves are gate valves or diverter valves, not ball valves.

This was the solution. I never realized that could be opened and closed. The people that closed the pool must have closed it. Thank you JamesW!!

Every year I learn something new. Now it's time to great rid of the green water.
