It is such an irritating moment if using a toilet with no water flush. Your toilet’s water flushing actually comes from the water supply valve mounted on the wall behind the toilet. This valve connects to the tank by a fill valve, which regulates the filling of the toilet and keeping it clean. You need to see each of these components in your toilet system to see the problem before repairing the toilet with no water. It is moderately easy work to be done by you so here are the steps.
You will need:
- Teflon plumber’s tape.
- Fill valve.
- Water supply hose.
- First, check the toilet water supply valve located on the wall behind the toilet, which supplies the water in the tank for flushing. Follow the water supply pipe or hose connected on the underside or back of the tank until it meets the valve to locate the valve. Rotate the valve counterclockwise as far as it will go to make sure that it is in the open position.
- Then, check for any kinks on the water supply hose. Water will not be able to reach the tank if the line between the water supply valve and the tank is kinked or bent. Straighten out the hose before attaching it to a wall with a clamp to keep it up and out of the way.
- Change the water supply hose if it contains rust or debris, which would block the hose from supplying water to the toilet flush. To replace the hose, turn off the water supply valve by rotating it clockwise. Unscrew the metal coupling on the hose from the tank and wrap the threads on both of the water supply valve and the tank inlet using Teflon plumber’s tape. Reattach the hose to the tank inlet and water supply valve before turning on the water supply.
- The fill valve connects to the water supply hose and fills the toilet with a supply of water for each flush. Although it is possible to repair a fill valve than buying new one, the older fill valve may not be up to code if repaired.
- Buying a new fill valve is more efficient and inexpensive as well especially for fill valve with integrated floats. To replace it, shut off the water supply before disconnecting the supply hose.
- On the underside of the tank, unscrew the plastic retaining nut and lift the valve out from the tank. Put a few dabs of silicone grease to the underside of the washer on the new fill valve before setting it in the bottom of the tank.
- Screw the retaining nut onto the threads at the bottom. Use plumber’s tape to wrap the inlet and reconnect the hose. Turn on the water supply to test.
