    Hi

    Even though I borrowed a FLIR infrared camera to check heat run location I apparently missed one return leg and naturally, drilled for a tapcon right dead center of the tubing:eek:.

    The tubing is 1/2" Wirsbo hePEX which can be used with propex expander system or QS20 compression.

    Since the propex repair fitting is all plastic versus the brass QS my thinking is it would be better in concrete since it is impervious to corrosion where the QS must be protected to prevent corrosion.
    Also, the compression is likely going to be more finicky to install given I really have very little wiggle room with the tube held firmly by the concrete floor.
    Also with the QS20 if you don't get the tube seated fully up the fitting it will not seal properly and may be hard to get just right with the restricted space.

    So the question, for a repair in slab is it ok to use the propex or is there some reason the compression is best?

    TIA
    Steve

    To be clear you're recommending: Q4775050 ProPEX EP Coupling
