How to Replace a Toilet Water Supply Line · Step 4 of 4
In this video
Slowly turn the main water supply valve back on by turning it counter-clockwise. Listen for the toilet tank to begin filling and carefully check all new connections (at the T-valve and hoses) for any drips or leaks. Once you've confirmed there are no leaks, turn the shut-off lever on the T-valve to the 'on' position (pointing up). Test the sprayer by aiming it into the toilet bowl and pressing the trigger. The water pressure is shown to be strong. Remember to turn the T-valve lever back to the 'off' position (pointing down) after testing.
Goal: Check for leaks and test bidet functionality
- Turn the water on slowly to avoid sudden pressure surges that could cause leaks.
- After testing, turn the T-valve lever to the 'off' position to relieve pressure from the hose and prevent leaks.

FAQs
How difficult is it to replace a toilet supply line, and how long does it usually take for a beginner?
This is a beginner-level plumbing project, typically taking only 15-30 minutes to complete. The most time-consuming part is often ensuring all connections are leak-free. The cost is usually just for the new supply line, which is quite inexpensive.
Why is a braided stainless steel supply line recommended over other types, like plastic or standard polymer lines?
Braided stainless steel lines offer superior durability and burst resistance compared to older plastic or non-braided polymer lines. They are less prone to kinking and cracking over time, providing a more reliable and long-lasting connection to your toilet. This minimizes the risk of catastrophic water damage from a burst line.
What should I do if I find a leak after installing the new supply line and turning the water back on?
First, immediately turn off the water supply again at the shut-off valve. Gently tighten the connections a small amount (about a quarter turn) with your adjustable wrench. Ensure the rubber washers or cones are properly seated and not pinched. Avoid overtightening, as this can damage the fittings or line.
What if the water shut-off valve behind the toilet is old, stuck, or won't completely stop the water flow?
Do not force a stuck valve, as it could break and cause a larger leak. If the valve doesn't fully shut off the water, you'll need to turn off the main water supply to your house before proceeding. This might also be a good opportunity to replace the old shut-off valve itself, as a separate, slightly more involved project.
