My biggest question is, why do they insist on connecting the black and gray/bath tanks together to the common wye fitting without any flexible fitting to allow a bit of movement? We had a failure, while under warranty, which was repaired and covered by Keystone, and was the black valve and both the square flanges on either side of the valve broke out two of the four corners at the bolts. When CW in Boise made the repair, they installed a flexible coupling. I wonder how many tank failures are caused by this restricted movement in the plumbing off of the tanks?
