How to Replace the Water Supply Hose on a Toilet

Replacing a water supply hose on a toilet regrettably may become very self-evident when it has to be done. The supply hose will generally form a crack in the tubing, causing water to cover the floor. The worst part of this is the cleanup of the water. By following a basic process, the replacement of the supply hose is a quick fix to a common problem.

Things You'll Need

• Plastic bucket Plumber's pliers or channel locks New water supply hose of the proper length

Instructions

1. Shut off the water supply valve that feeds the hose to the toilet. Be sure to firmly seat the valve. Seating the valve is the method of a firm and final twist to the valve handle seating the rubber gasket against the interior stop. Do not use the pliers for this, only your hands, as the extra force by the pliers may damage or break the valve seat causing it to fail and leak.

2. Flush the toilet by holding the handle down to release all the water from the tank.

3. Place the bucket under the hose to the tank connection.

4. Loosen the flange nut that holds the hose to the tank with the pliers or channel locks. Once the nut is loose, finish removing the nut with your fingers. Allow any excess water to drain into the bucket.

5. Remove the hose from the water supply valve connection. A little bit of water may spill from the hose onto the floor.

6. Attach the new hose first to the water valve supply connector and tighten with the pliers. You may have to hold onto the valve when tightening the hose nut connector to keep the valve from turning.

7. Connect the new hose to the toilet tank. Start the threads of the nut connector with your hands and finish tightening with the pliers.

8. Turn the water supply valve on and check for leaks. You will want to wait until the toilet tank is full so the new supply hose is under full line pressure for testing.

Tips & Warnings

• You may want to have some old towels on hand to mop up any excess water around the toilet base. Keeping an extra supply hose around the house may not be a bad idea as sometimes this type of repair can occur at the most inconvenient of times.
