1. Take Away the Outdated Valve
The current valve’s installation method determines the connection you’ll utilize next. Potential examples of this are:
Valves for Compression
It uses a compression nut with a hexagonal shape to keep it in place. The valve body may include two flats on the side or a pair of hex flats at the compression nut. Using pliers, remove the pipe from the bolt. The old valve’s compression ring and nut may be thrown away once removed from the pipe.
Sweat Restricting Valve
You’ll need to use a tube cutter to sever the connection between the new and replace shut off valve for toilet and the copper line that supplies water from the old valve. Turning the pipe cutter’s nut to a tighter setting will help it cut through the metal pipe more smoothly. The length of the pipe protruding from the wall should be sufficient for mounting the new component.
Threaded fittings are identified by threads and flex caps at the point where the metal pipe and valve meet. A pipe can be made of copper or galvanized metal. When it has to be replaced, use another threaded valve.
2. Arrange for the Installation
When cleaning the exposed tubing, use an emery cloth. When switching from a sweat valve to a compression valve, it is necessary to sand off any remaining solder before installing the new outer sheath, nut, and sleeve.
It is required to remove some of the solders from the pipe to allow the new sweat valve to be fitted onto the pipe. Soldering a new quarter-turn valve requires detaching the stem and wire, brushing the surface, then applying flux and heating the valves until the solder is pulled in. With a moist towel, remove any melted solder pooling on the surface.
Use a wire brush to remove the seal tape from the threads of a threaded-style valve before installing it. Re-seal them with thread seal tape, but this time use fresh tape. You also have the option of making use of a pipe thread compound. It is recommended that the pipe be sanded down using a sanding cloth before installing a push-to-connect valve.
3. How to Replace Toilet Shut Off Valve?
Compression Type Valve
Remove any burrs from the copper pipe using a deburring tool, which is not required for PVC pipe. Next, insert the pipe into the compression nut with the threads pointing away.
Slide the new valve as far as it will go over the pipe, ensuring that the outlet points upward before you squeeze the compressive ring onto the tube. As you use one crescent wrench to keep the valve body in place while you tighten the nut with the other, you can be sure that the compression nut is securely fastened to the input of the valve.
Plug and Socket Valve
After the valve has been secured to the pipe, turn it to move the flux around. Put the valve in the open position to stop the inner washer from melting. As the flux begins to bubble, heat the fittings with a propane torch and solder the junction, using half an inch of lead for every half an inch of the tube diameter. The excess solder should be removed from the intersection utilizing a dry cloth before it hardens.
Toggle Valve with a Threaded Body
Secure the valve to the pipe using your hands. First, hold the pipe in place with a pipe wrench, then use an adjustable wrench to snug up the valve. Do not overtighten the valve since this may cause it to break.
Quick Connect Valve
The replace toilet shut off valve onto the pipe should be even and square. Keep going down until the gate bottom out, and then give it a little tug to ensure it’s secured. Then, the mechanism within will create an impenetrable seal. As long as enough tubing protrudes from the wall, a quarter-turn push-fit ball-style valve may be utilized instead of sweat and compression fittings for a tool-free alternative.
4. Resurrect the Water Service
Once you’ve reconnected the water lines and turned on the main water valve, you’re all set. Loosen the toilet’s shut-off valve by turning it anticlockwise.
While the tank fills with water, look for leaks in the area where the replacement valve was installed. If this is the case, the water supply must be turned off, the lines must be drained, and the compression nut on the valve must be removed. The connection should be rechecked after the plumber’s tape or putty has been applied to the valve’s threads.
