That is a check valve per Rip Van. There is one in the pump and if it fails you can install one like this, been there done that.Hi all,
I am trying to determine what the circled object is the attached picture. Is it the strainer? If so, what is the cap for? Is it backwards? The arrow is pointed towards the pump.
Thank you
Joe
I think it is for a winterization kit install, so you can draw antifreeze straight from the bottle.
