How to Remove and Install an Angle Valve?
3 Answers
Angle valve removal and installation method: 1. First, turn off the water source, i.e., close the main valve. 2. Remove the metal hose connected to the angle valve by turning it counterclockwise, and use a special wrench to grip the triangular position of the angle valve and rotate it counterclockwise. Do not use excessive force during removal; angle valves are generally not installed very tightly unless they are rusted in place. 3. During installation, wrap 4-5 turns of PTFE tape around the threads of the angle valve, winding it tightly from the outside to the inside in a clockwise direction. Then, screw the angle valve into the pipe fitting in a clockwise direction, leaving 2-3 threads exposed to complete the installation. The following is an introduction to angle valves: An angle valve is an angle-type stop valve, similar to a ball valve, with its structure and characteristics derived from modifications of the ball valve. The difference between an angle valve and a ball valve is that the outlet and inlet of an angle valve form a 90-degree right angle. Angle valves are also known as triangular valves, angle-shaped valves, or angle water valves.
Disassembling and installing an angle valve isn't that difficult, you can do it yourself at home. First, turn off the main water supply to avoid water spraying and wetting the floor. Then use a wrench to loosen the fixing nut on the angle valve, being careful not to twist it crookedly, and slowly remove it. Clean the old sealing gasket or tape at the connection, wrap new PTFE tape for sealing when installing the new angle valve, and tighten the nut. Finally, turn on the water supply to check for leaks, and if there's a leak, tighten it again. It's recommended to regularly check the condition of the angle valve to avoid the hassle of repairing leaks, and keep some PTFE tape at home for quick fixes of minor issues.
I've also disassembled an angle valve before, and the process was quite simple. After turning off the water valve, use pliers to loosen the nut, being careful not to apply too much force to avoid cracking it. When replacing the old valve with a new one, apply some grease to prevent rust and increase durability, then screw it back on and test for leaks. The key point is that doing it yourself saves money and builds skills, similar to car parts maintenance – you need to be meticulous to avoid issues. Regularly check and repair household water pipes to stay prepared for emergencies.
