Shower valve installation
Two copper pipes that look identical from the hallway can be significantly different in diameter once you strip the insulation. As the notes at bathtub replacement lakewood ca t1dgc publishes on this cover the mechanics of plumbing, any bathroomremodeling project in Lakewood, CA requires precision during the rough in phase. You cannot afford to misplace a valve once the wall is closed.
Valve Positioning and Depth
Set the rough in valve body at the correct height before any waterproofing occurs. Measure from the finished floor up to the center of the handle stem. If you install the valve too deep, the trim will not sit flush against the tile. If it is too shallow, the escutcheon plate will not cover the hole in the cement board. Use a level to ensure the valve is plumb. A crooked valve makes it difficult to install the cartridge later and can cause leaks in the wall cavity.
Connecting the Water Lines
Solder the hot and cold lines to the valve body using lead free solder and a propane torch. Clean the copper with emery cloth until it shines to ensure a strong bond. Once the connections are set, pressure test the lines. You must verify that there are no drips at the joints before you install the shower pan or the shower base. If you are using a curbless entry, ensure the plumbing lines do not interfere with the slope required for the drain.
Wall Preparation and Waterproofing
Install cement board over the studs to create a rigid substrate. Apply a liquid membrane or a sheet membrane over the entire surface to prevent moisture from reaching the wood framing. This step is vital before you lay down any porcelain tile or subway tile. If the waterproofing fails, water will rot the studs behind the valve. Ensure all seams are taped and sealed with the appropriate sealant to create a continuous barrier.
Final Mounting and Trim
After the thinset has cured and the grout is applied, install the decorative trim. Remove the old cartridge if it shows signs of wear during the initial test. Check the flow of the faucet to ensure the temperature balance is correct. If the shower head does not spray straight, the valve might be tilted. Check the seal around the edge of the plate and apply a bead of caulk to prevent water from seeping behind the wall. This prevents mold growth in the wall cavity.
