When Should You Replace Water Shut Off Valves?

Test if all the pipe normally flows when you open the valve. If the valve is stuck, or you can’t close or open it, this probably needs to be repaired. A shut-off valve can last for 10 to 25 years, but the average is 20 years. But you have to exercise these every year or two.

How to Replace Water Shut Off Valve

To replace your shut-off valve, you have to consider some things while doing this by yourself. Here you’ll get some steps to follow to do the task.

 

STEP 1

Identify the Valve Connection Style

Before you begin, identify the valve connection style for replacing the water shut-off valve. A shut-off valve can be connected to copper plumbing pipes in two ways-

  • Compression Fitting
  • Sweat Fitting
  • Threaded Fitting

If you have galvanized pipes in your older home, we recommend hiring a plumber to assist you in replacing them. The process of unscrewing the old valve and replacing it may appear simple. It can be a nightmare if the pipe is internally rusted or if the threads are rotten.

Moreover, if you have PEX or plastic pipe in your home’s plumbing, purchase a quarter-turn shut-off valve once you’ve determined the connection type. You’ll also need some necessary tools and materials to do the task of changing a sweat valve.

●      Sweat Valve

This type of shut-off valve lacks hex flats, so you need to replace it with a sweat valve or a compression valve.

●      Compression Valve

Look at the part of the valve that is closest to the wall. Find the hexagonal compression nut along with the hex flats. Find two flats on the sides of the shut-off valve, if your water valve has a compression nut without any hex flats.

●      Threaded Valve

Where the steel pipe enters the valve, you need to find the threads and hex flats.

STEP 2

Turn Off the Water for a Plumbing Repair

Before making any replacements, turning off the water is a good idea. To avoid a mess, you must know how to switch off the water before repairing a leaking pipe or replacing a water shut-off valve.

  • When a faucet leaks, a toilet overflows, or a washing machine drips, the first step is to turn off the water locally. It’ll allow you to continue utilizing other water pipes while the repair is done.
  • When your water heater pipe is leaking, turning off the hot water outlet pipe prevents any structural damage. A red handle will mark it.
  • You need to shut off the main water valve if the pipe that leaks doesn’t have any local shut down valve.

 

STEP 3

Test the Shut-Off Valve

Check if there is any sign of corrosion on the outside of the shut-off valve, like white, turquoise, or brown residue. The signs mean that your valve may be corroded.

Let’s turn the knob or level of the valve to check if it’s working well. If you see any corrosion or stocks, you need to fix or replace them. But replacing it will be the best option.

STEP 4

Remove the Valve and Stop the Leakage

Head over to the local shop or search online and find a replacement valve. Though currently, you have a gate valve, try to replace it with a ball valve. The valves in this category are less prone to leaks, and they last for a longer period of time.

●      Remove the Old Valve

You’ll see two or more pipes connected to your valve that bring water to it or to other areas. Looked at the compression nut and used the wrench to unscrew the valve. In order to prevent the valve from turning, you must hold the knob with your wrench. The valve will slide right off the pipe now, and then cut the pipe with valve solder or hacksaw. It is important that you cut it as close as possible to the compression nut.

●      Prepare the Pipe

In the place where the valve used to be on your pipe, there will be some threads. Use a cloth and clean them carefully to remove the residue. Thread seal tape will keep the valve and the pipe sealed when wrapped around it.

●      Install the New Water Shut-Off Valve

Slide the new shut-off valve onto the pipe and like it with a compression nut. Now reattach the water supply lines and grab the wrench to tighten everything.
