An RV tap may be leaking for a number of reasons. Anything from old, corroded parts to simple loosening due to travel may cause a leakage. By just taking apart the tap, it is often apparent exactly what part has malfunctioned. After that it is just a question of replacing that piece at a local home improvement store. Sometimes, however, the tap itself may be broken, which requires a replacement. RV taps are remarkably similar to those in a residential home, so the job is easy.
Instructions
1、Turn the water supply off and let the bathroom sink faucet tap run until the water lines are empty. Under the sink, the tap is connected to the hot and cold supply lines. Unscrew the connections and drape the supply lines into the bucket to catch any water remaining in the pipes. You may need channel-lock pliers to unscrew the connections if they are on tight. Clean and discard any old Teflon tape that may still be on either the tap or the supply line connectors.
2、Unscrew the plastic nuts under the sink that hold the tap to the sink and take off the old tap. An O-ring should be between the plastic nuts and the underside of the sink. This is often the part that fails.
3、Clean the sink where the old tap was as debris can cause a bad seal and allow water to seep under the tap and into the cabinet below.
4、Attach the new mounting plate to the sink and tighten until snug, but do not apply too much torque as this may break the thread or crack the tap and sink tap.
5、Apply the plumber's tape to the threaded ends of the water lines on the new tap before inserting it through the mounting plate. Trying to do this under the sink is difficult because of limited space.
6、Place the new tap into the correct holes on the mounting plate. Screw the O-ring and the plastic nuts that came with the new tap onto the tap and tighten with the channel-lock pliers. Apply just enough torque to create a seal with the O-ring
7、Attach the supply lines to the tap, making sure to connect the hot supply line to the hot water line in the tap and the cold supply line to the cold tap line. Tighten with the channel-lock pliers. Turn on the RV water supply and open the tap to test for leaks.
