My
Trillium Outback came with 2 Watts 90 degree P-620C Elbows (plastic of some sort) used to connect the water tap to the exterior inlet. Both cracked and leaked. Here is the product:
Watts P-620 Union Elbow 1/2
While I may have suspected trapped water freezing thus causing the cracks, it doesn't seem to make sense because one was suspended higher than the other and my pipes were dry all winter (or so I thought). So I wonder if it was not vibration during road travels. The pipe/fittings are not mounted in the center and span approx 1 1/2 feet horizontally inside the sink cabinet.
The location of the crack on each fitting is the point of most stress, on the inside corner. Anyone have similar fittings and cracking experiences?
