Release a corner valve

The angle valve is little noticed. But if a faucet or a mixer tap to be renewed, it should often be closed after many years, but it can not be closed. How to solve a corner valve and make it workable again, we have summarized below for you.

Angle valves everywhere in the household

Angle valves represent the professional connection between water supply of the house with the connected fittings. They can be found, inter alia, at the following connections:

  • Bathroom sink
  • Toilet water flush
  • Kitchen mixer tap
  • Bath and shower

Often ignored for years

Thus, the angle valve is usually well hidden under the sink or the bathroom sink and is almost never noticed. If a new mixer tap is now installed or if you want to connect a dishwasher to the angle valve, the water must be turned off at the valve.

Angle valve is stuck

In many cases now when trying to turn off the water at the angle valve, found - it is stuck. So it has to be solved again. Especially in regions with very calcareous water, this problem can occur more frequently. Lime deposits in the niches around the valve, which literally sticks to the valve.

The release of the angle valve will not work anymore

The valve can no longer be released. In addition, inferior quality corner valves are often equipped with a plastic screw plug. If you use a water pump pliers, the plastic will break immediately. Now you have several options to still solve the angle valve.

Therefore, you must now make the angle valve feasible

Not always the screw is completely solid. Now you just can not try to close the valve completely. Instead, gently move the valve to close the direction and then back again. Repeat this, the angle valve can often close completely after several attempts.

The method with the hammer

If you have a particularly stubborn corner valve, you have another option that you may know from the heating thermostat: take a small hammer. The body of the angle valve is usually formed as a square, so you can grasp him not only with a pair of pliers, but also with a suitable open-end wrench optimal.

If it jams too tight, you will need a new angle valve

Here you perform some emotional strokes with the hammer. Better less firm, but several times. Hit the corner valve 10, 15 or 20 times. But always with feeling. Due to the triggered vibrations, the limescale dissolves in many cases.

When turning up, you then proceed as already described - a little bit ahead, a little bit back, etc. If all this does not help, you have only one option left: you must replace the angle valve.

Tips & Tricks

With a new angle valve, you can take steps to minimize the risk of it being stuck. Never turn open an angle valve for everyday use. Open it completely and then turn the valve back a little. If limescale or other dirt deposits, you can still turn the angle valve in both directions to release it. This significantly increases your chances of making the valve workable.
