Helps to adjust the suction between your skimmer and main drain. Fits the SP107 and SP1071 skimmer.
I bought a new Hayward SP1017FV float.
It came with an o-ring.
Where does the o-ring go?
Does it go between the bottom of the valve and the bottom of the skimmer?
The cover that is held on by a screw. Should it completely cover the hole,as shown in the photo? Our should it be left partially open?
