Weird thing happening to pool
I noticed the other day that my skimmer filter wasn't working. So I shut everything off and noticed that the flapper on the bottom of the float valve diverter was broken off (couldn't find it!).
So I did 2 things. I replaced my 35 year old pool filter assembly with a new Hayward unit (my old one was leaking water at the seams). I also bought a new flapper piece for the diverter valve.
Now, I can't get the skimmer to flow correctly. When I turn the pump on it empties the skimmer area in about 3 seconds, which closes the float valve and keeps it closed because of the pump suction. I believe it then works on the bottom drain. Not sure where I should set that flapper...should it be fully closed? I only had it partially open. It just seems like there's so much suction...too much. Maybe the new filter is too good.
