This week I found one of my return nozzles on the floor of the pool. Turns out it is a slip-style fitting (no threading on fitting or return pipe).
After reading several related posts, it seems that these slip-style fittings are supposed to be knocked into the return pipe, and are meant to hold fast without glue or adhesive.
I placed the nozzle back into the return and gently hammered it in place. (Place a 2x4 over the fitting so that the hammer did not damage the fitting.)
That held in place for several hours under pressure from my , but then loosened and dislodged again. I definitely took it easy re-inserting the fitting so as to be on the safe side and not damage the plumbing.
My next step is to really whack that fitting back into the return pipe, but I am hesitant to move forward before getting more advice.
Anyone encounter this scenario before? What is standard practice to get these slip-style fittings in place?
This is a superb form that has steered me right on several issues in the past. Any commentary much appreciated.
