I’m not sure if my main drain is on. I swam down there tonight And squirted some colored water and it doesn’t seem to uptake. I’m going to try to attach a picture of my equipment. How do I tell and make sure my main drain is functioning. My main concern is I have in floor cleaners and I want to suck up all the dirt and junk. I can’t figure out how to attach a file picture. I’ll try to add later.
