In looking at my pool equipment, in the skimmer there are 2 holes at the bottom (below the basket) Does this indicate that the main drain is connected through the skimmer?
Also, there is an old looking Jandy valve in front of the pump, would this be used to control the flow from the main drain or skimmer?
Should I do anything with this while cleaning the pool? there is a lot of debris and what I am sure is algae, by mixing the flow between the skimmer & main drain (if this what this valve is used for) would this help clear the bottom of the pool?
Should I even try to do some testing with this old valve or am I asking for trouble? This pool had a lot wrong with it since the house was empty for so long so i'm just trying to get the hang of it and understand exactly what's going on
