My hot water line in the galley sink leaks when external water supply is hooked up. Have hand tightened the connection to faucet but am concerned about applying too much torque to the connection as they are plastic (vinyl?) connection. Suggestions??
Since it appears that this connection only leaks when hooked up to city water the problem may very well be too much water pressure. If your RV is equipped with a built-in Water Pressure Regulator, it may not be working properly. If this leak is indeed caused by too much water pressure, you may have other hidden connections that may be leaking in your RV.
