Fix a Leaky Two-Handle Bathtub Faucet: A Step-by-Step Guide · Step 5 of 5
This DIY guide demonstrates how to fix a leaky two-handle bathtub faucet by replacing the valve stems. The project involves several steps: First, turn off the water supply to the bathtub, including the hot and cold water lines under the sink or behind an access panel. You may also want to turn off the main water supply. Second, Remove the faucet handles by taking off the decorative caps (if any) with a flathead screwdriver, unscrewing the handle screws with a Phillips head screwdriver, and gently pulling the handles off. Third, remove the old valve stems using an adjustable wrench to loosen and remove the packing nuts. Then, pull out the stems, and take note of the orientation and positioning of all parts for reassembly. Take the old stems to the hardware store to find matching replacements. Fourth, install the new valve stems, ensuring the rubber gaskets at the bottom create a good seal. Hand-tighten the stems first, then secure them with the adjustable wrench, being cautious not to overtighten. Fifth, reassemble the faucet by putting the handles, screws, and decorative caps back in place. Slowly turn the water back on and test the faucet for leaks. If any leaks remain, re-tighten and double-check. Finally, seal around the base of the faucet with silicone caulk to prevent water seepage.

FAQs
Do I really need to turn off the main water supply, or is turning off the lines under the sink enough?
While turning off the hot and cold water lines directly to the bathtub faucet is often sufficient, it's a good safety practice to turn off the main water supply as well. This prevents accidental water flow if the individual shut-off valves are old or fail, minimizing the risk of floods during the repair process.
How do I ensure I purchase the correct replacement valve stems for my specific two-handle bathtub faucet?
The most reliable way is to remove your old valve stems and take them to the hardware store for an exact match. Pay close attention to the length, number of splines on the handle attachment, and the type of rubber washers or seals. Knowing your faucet's brand and model number can also help, but the old part is the best guide.
My faucet is still leaking after I've replaced the valve stems. What should I check next?
First, ensure all connections, especially the packing nuts and valve stems, are securely tightened, but not overtightened. Check that the rubber gaskets or O-rings on the new stems are properly seated and undamaged. Sometimes, a leak might originate from the faucet spout base rather than the handles, which could indicate a separate issue with the diverter or spout O-rings.
How long should a beginner expect this repair to take, and what's the typical cost involved?
For a beginner, this project typically takes 1 to 2 hours, assuming you have the correct replacement parts readily available. The cost is usually low, primarily for the replacement valve stems, which can range from $15 to $50 per pair depending on the brand and complexity.
