How reliable is the plastic plumbing used for water supply lines in RV's? I've seen connectors with crimped ferrules and threaded compression type connectors. Given the damage (lotsa $$$) that a leaky connection can cause, and the adverse conditions to which connections are subjected (vibration, wide temperature swings, varying supply pressures, etc.), is there a better solution than the plastic lines and fittings? What about sweated copper lines and fittings, such as are used in non-mobile houses?
I'm asking this question since my son's house is plumbed with crimped ferrule type plastic supply lines, and there is a huge class-action suit being brought by homeowners whose homes have experienced major damage from leaking water supply lines of this material. My concern is, if a stationary home plumbed with this stuff is at risk of damage, what about an RV, where the conditions are much more severe?
