A mounting system made up of a valve isolation assembly comprising first and second inlet ports and first and second outlet ports along with a pair of crossable pressure lines made up of first and second pipes. The first and second pipes respectively define first and second upper ends and first and second lower ends. The first and second pipes also define first and second middle portions. The upper ends of each first and second pipe are operably coupled to the first and second inlet ports of the valve isolation assembly. In one embodiment the first and second middle portions each define a quarter right-handed helix turn. In another embodiment the first and second middle portions each define a quarter left-handed helix turn.
