Important Information for Installing
the HS5000 valve in a Down Orientation
Avoid Potential Issue
One of the advantages of the HS5000 is that it can adjust for wall
thicknesses from 1/2" to 1 1/2". As shown in Figure 1, with 1/2" sheetrock,
the pipe fitting is pushed all the way to the back of the wall. Problems can
arise when the bottom hole is too far forward. The pipe is too short to flex
enough, thus putting a large amount of pressure on the back of the valve.
We have actually seen valves break under these extreme conditions.
Solution
Drill a larger hole (2 9/16") to allow the pipe to have some movement (see
Figure 2). Before installing the valve, reach in and make sure the pipe can
flex forward and back inside the wall. Sometimes the foam insulation will
need to be broken up with a long screwdriver.
If you find that it is going to require a lot of force to push the pipe back, it
is a good idea to put a shim between the pipe and the front wall board, to
take the pressure off of the valve, as shown in Figure 1.
