Your faucets are most likely used on unique installs, especially different materials on wall mounts. Appreciated the side to side adjustment but had to come up with my own way of securing it to a stainless steel counter/backsplash.
Some sort of mount other than the supply lines would be helpful.
Dishmaster wall mount faucets are designed to mount on two 1/2' pipes that are 8' apart on centers. That dimension is very standard. The pipes MUST be firmly attached to the home's framing structure for stability.
