How to Replace a Toilet Water Supply Line · Step 1 of 4
In this video
The first step is to prepare for the toilet removal. This involves turning off the water supply using the shut-off valve located on the wall behind the toilet. Once the water is off, flush the toilet to empty the tank. Hold the handle down to drain as much water as possible from the tank and bowl. Disconnect the water supply line from both the shut-off valve and the bottom of the toilet tank, using pliers if necessary. Have a small container ready to catch any residual water from the line or tank.
Goal: Toilet Removal
- Place a towel or small bucket under the supply line connection to catch any remaining water.

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.
