I am replacing a tub/shower faucet and noticed the grey PB tubing.
The home is built on slab and apparently uses Vanguard Thermoguard Potable Tubing 3/4" and 1/2"(PB2110 SDR-11) to 1/2" copper at fixtures.
Supposedly not part of lawsuit because of the copper fittings and copper crimp rings at unions.
Q: Should we still be concerned now that we are hitting 16 years?
Q: What about fittings from PB to Sharkbite PEX?
