Next, install the overflow assembly. Apply a bead of sealant to the back of the bathtub around the overflow opening. Also apply sealant to one side of the tapered overflow gasket and place it onto the overflow pipe fitting. Press the overflow assembly firmly against the back of the tub, aligning it with the hole. From inside the tub, place the chrome overflow cover plate and secure it by tightening the provided screw with a screwdriver. Do not overtighten. Once the overflow is secure, ensure all slip nuts on the PVC drain pipes are hand-tightened to secure the connections.
Goal: Seal and install the overflow assembly
- Hand-tighten the PVC slip nuts first, then give them a final quarter-turn with channel lock pliers if needed, but avoid over-tightening plastic threads.

FAQs
How accurate is the 12-hour estimated time, and what factors could significantly extend this project for a DIYer?
The 12-hour estimate is for an intermediate DIYer in ideal conditions. Unexpected issues like significant wall damage, corroded old plumbing, or difficult-to-remove fixtures can easily double the project time. Always allocate extra time for unforeseen challenges, especially during demolition.
What is the absolute first safety step, and what should I do if I can't turn off the main water supply?
Always turn off your home's main water supply before starting any demolition or disconnection. If you cannot locate or operate your main shut-off valve, contact a professional plumber immediately. Proceeding without cutting the water can cause severe flooding and significant property damage.
Beyond the basic hand tools, what specialized tools or materials are crucial for ensuring a leak-free faucet installation with PEX or CPVC?
For PEX, a dedicated PEX crimp tool and appropriate crimp rings are essential for secure connections. If using CPVC, you'll need CPVC primer and solvent cement. Always use plumber's tape or thread sealant on all threaded connections and plumber's putty for the tub drain assembly to prevent leaks.
What is the most common mistake DIYers make that leads to leaks after installation, and how can I avoid it?
The most common mistake is failing to properly seal connections or not adequately tightening fittings. Ensure all PEX/CPVC connections are correctly crimped or glued, and all threaded connections are wrapped with Teflon tape and firmly tightened. During the leak test, turn water on slowly and meticulously inspect every joint for drips.
