sink hose replacement
I have a 2015 1950 pop-up, and had trouble with the sink drain hose splitting where it connects to the p-trap (see photo). I contacted FR and they claimed to not have heard of this problem. After sending pictures to them, they sent me a few feet of replacement hose. I figured out what was happening. When I attached a drain hose to the outside socket, it was twisting, resulting in the the splitting. When I reattached the new hose, I put a screw on both sides of the part closest to the wall, on the outside. I could not get to the nut on the inside to tighten it. (see photo of one screw.) Now it no longer twists when I attach the drain hose. No more splitting. So far, no problems with the water hoses.
Looks like the pictures are sideways, sorry, but I hope this helps.
The picture of the p-trap, with black tape, was a temporary fix.
The picture of the outside shows the ring which slipped. Couldn't reach the inside ring to fully tighten it so it would not slip. The screws stopped the slipping.
