In the event of an accidental piping puncture, do not panic, the system is a closed loop so the amount of water that may leak is limited. That is assuming there is not an automatic refill valve with the security valve left open.
When installing new wall or ceiling fixtures, (such as decorations, lighting fixtures, blinds, frames, etc.) the usage of a thermal camera is recommended to reveal the piping hidden behind drywall.
An unknowing occupant may accidentally puncture a radiant tube within the Ray Magic® panel with a nail or a screw by installing new fixtures on the ceiling or walls.
The damaged section can be repaired using simple 8mm press fit couplings and, if required, 8mm PEX tubing.
The damaged section can be repaired using simple 8mm press fit couplings and, if required, 8mm PEX tubing.
Follow the instruction below:
- Turn off the radiant system or the specific zone where the puncture occurred.
(This could also be done by manually turning off the manifold loop related to the particular zone)
- Extract the nail or screw.
Ensure you turn off the zone valve before extracting the nail or screw.
- Cut a square opening and remove (about 4” x 4”) the drywall covering the area where the piping is punctured.
- Using a pair of scissors, cut the aluminum heat transfer plate around the punctured pipe. Completely remove the aluminum plate around and below the pipe.
- Remove the EPS below the pipe as shown.
- Using a cutter or knife, cut out the punctured portion of the pipe by cutting in two points with a distance of approximately ⅛″. Make sure the cuts are clean.
- Procure a 8mm press-fit coupling. Messana recommends the John Guest Speedfit 5/16″ (8mm) straight connector (PM0408S).
- Insert the 8mm pipe into the coupling all the way until it hits the bottom of the fitting. Try to pull out the pipe to make sure that it is properly seated on both sides.
- If the damaged segment of piping is more than ⅛″, perform a split by using a piece of the supplied 8mm pipe as shown.
- Tape and mud the drywall. Let dry. Sand if needed. Repaint.
