Free Yourself From A Dribbling RV Shower
This article will show you step by step how to remove and replace your shower faucet and replace the vacuum breaker with a non-dribbling “D” Spud (also from Phoenix Faucets). I will discuss shower heads in a later post.
Begin by turning off the water to the RV including the water pump. Next locate the access panel behind the shower and remove the retaining screws exposing the plumbing. Remove the shower hose from the vacuum breaker. Unscrew the hot and cold water connectors and remove the plastic retaining nuts holding the faucet in place (I attached a bungee cord around the water lines so I could retrieve them if they fell to the side behind the wall). Push the fixture into the shower stall enough so you are able to finish extracting it from inside the shower. Remove the faucet and clean the shower wall around the faucet.
Prepare the new faucet for installation by removing the vacuum breaker that came with the unit. Put plumber’s dope or teflon tape around the threads of the “D” Spud. If you use teflon tape be sure to trim the excess off so it does not block the water flow. Install the “D” Spud using an allen wrench, star wrench or a large flat blade screwdriver. Place the black plastic mounting flange on the new faucet. Insert the new faucet through the existing 4 inch center holes. You may want to coat the mounting flange with clear caulking prior to insertion. Screw on the new plastic retaining nuts by hand until the faucet is firmly in place. Replace the hot and cold water connectors making sure the rubber gaskets are in place inside the water connectors.
Reattach the shower-head hose and turn on the water. Before you “button up” the back cover place a dry paper towel around each of the water connectors and turn on the shower allowing the water to run. Remove the paper towel making sure it is completely dry. If it's wet you either need to tighten the connectors or replace the gaskets. When you are satisfied everything is dry and working reinstall the back cover and put your wife’s stuff back where you found it.
