Below is a picture of my location of leak. These two pipes are my returns, however I am confused as to why there is a 3 way valve here. I assume one return goes to the pool but what does the other go to?
I have never turned this valve after purchasing the house 4 years ago. Could this maybe be a valve to drain the pool?
I have a leak above this and the only way to repair is to replace the 3 way valve (a 50 dollar part) so I am wondering what purpose this is serving.
