Water not coming through one of the returns
I have an in-ground pool with two returns. Today I noticed that water doesn't seem to come through one of the returns. I put my hand in front of it and couldn't feel anything. The other return shoots water just fine and everything else seems working okay.
What seems to be the problem? Does that mean that the pipe leading to that return is clogged somewhere? Normally, this return shoots water less strong than the other one that is currently working okay. Not sure if that is relevant.
Any help would be greatly appreciated. Thanks.
