Gray plastic supply line, leaking at the fitting not the pipe
I Like To Fix
Polybutylene, installed 1978–1995. The pipe itself often survives; the acetal insert fittings do not. Failures cluster at connections and behind walls. Insurers increasingly decline or surcharge homes still on it, which is worth knowing before you renew.
This is most common in homes built roughly 1980 to 2000. The polybutylene and aluminum-wiring window, 150 amp panels, R-22 systems and first-cycle architectural shingle.
