My sister-in-law's new house has a basement guest room that backs onto
the equipment room. The gas hot water heater (domestic + radiant
heat) is located up against the wall that separates the two rooms.
When the HW tank cycles, the vibration/noise is transmitted to the
guestroom wall via the PEX hanging on the studwork and the supports
for the copper pipes coming out of the top of the tank (also attached
to the studwork - no drywall on the equipment room side of the
This makes a heck of a racket. I want to isolate the vibration from
the partition wall as much as possible.
a) do I have to stick with the J clamp mounts for the PEX or can I use
something with some flex to it (loop of copper strapping, say)?
b) how much support does the copper rat's nest on top of the HW heater
need? With my home tank, the copper is tied to the tank by the
fittings, then to the overhead joists. There is no intermediate
support to the vertical wall.
I'd post a picture if I could remember how/where to do it.
