how to replace rv shower faucet

Replacing your RV faucet maybe one of the techniques that are handy in maintaining the condition of your RV. You might not want to end up finding yourself trapped in between discomforts of having water leaks, no flows, or even contaminated water.

This article is a good way to understand the plumbing works of your faucets. Course through below and learn every time.

Things You Will Need


  • Faucet – Your new faucet system is recommended to be more or less the same as your old faucet. This lessens the complexity in the refurbishment accounting to the compatibility of the parts.
  • Tool kit – These tools will help carry out the plumbing steps of the process, including wrenches (i.e., crescent, open-end (different sizes)), screwdrivers (i.e. Philips, flat-blazed), and pliers.
  • Pipe Sealant tape – This plumbing tape will be used to tighten the setup and prevent the leakage of water.
  • Plumber’s putty – Putty acts as a sealant in which the material composition is silicone. Be careful not to contact these with plastic or natural stone as they can cause staining.
  • Brass Adapters – These tools are used to fit with the compression fittings of your new faucet and have them attached to the fittings of the water supply lines.

Step-by-Step Instructions


Step 1: Preparation

Remove unnecessary items from your kitchen sink for easy movement of your faucet modification.

Step 2: Turn off the water supply

Shut off the main water supply by turning off the water pump to prevent any flow of fluids within pipes and faucet during modification.

Relieve the water pressure within your faucet pipe system by opening your faucet.

Step 3: Remove sink drain joints

Remove the joints underneath the stopper first (black pipes). Turning them counterclockwise is the way to do it. You can loosen them as well using pliers. In doing this step, anticipate dripping water, as fluids may still be stored in those areas.

Step 4: Remove sink drain parts

Begin disintegrating the stopper assembly by unscrewing the nut and the horizontal pipe from the drain assembly.

The lower portion of the stopper is removed by rotating the part counterclockwise.

Step 5: Get the sink drain metal stopper from the sink

Retrieve the metal stopper inside by pushing the object upwards.

Step 6: Remove drain pipe accessories

Using pliers, remove the nuts, washers, and gaskets surrounding the remaining drain pipe part beneath.

Step 7: Remove the remaining pipe part

Push the loosened part upwards to remove it wholly, leaving an empty sinkhole.

Step 8: Clean the empty set-up

Clean the assembly within the hole through wipes, brush, or applying pressurized water. Make sure to place a catch basin underneath the hole.


Step 9: Remove the water supply copper tubing

Beneath the sink, begin disassembling the old faucet copper tubing of the plumbing lines.

Step 10: Remove pipe bolts and rod from the assembly.

Loosen the bolts on the stopper rods using a wrench. Push the rod upwards to remove it from the system. The rod should come out behind the faucet at the sink.

Step 11: Remove drain accessories and connections beneath

Remove the nuts and metal plates that hold the socket in place underneath using a deep socket tool.

Remove the pipeline connections by rotating the tubing parts. Make sure to catch the excess water stuck within these parts.

Step 12: Remove the faucet head.

Lift the faucet right out of the sink top.

Step 13: Faucet Replacement

Insert the new faucet head at the emptied water supply hole. Make sure the faucet tubing, nuts, and metal plates remain intact.

Step 14: Adjust water pipeline accessories

Fit in the brass adapter purchased at the lower portion of the assembly. Adjust the faucet at the sink top to make sure they are mounted properly.

Step 15: Install the sink drain pipe.

Wrap pipe tape around the sink metal tube to make sure gaskets are compatible and no leakage takes place.

Step 16: Improvise using a putty

Get a portion of the putty, and place it on the flannel portion of the sink tube.

Step 17: Assembly of new sink drain system.

Put the new assembly inside the sinkhole. Assemble back the gaskets, washer, and nuts beneath the sink. Follow by installing the new sink connectors. Upon tightening of the assembly, you can then remove the putty improvised at the sink top. Connect the water drainpipe with the new assembly.

Step 18: Testing of the new faucet system

Turn on the water supply and check for any leaks from the assemblies beneath.
