Stopcock cutting off

Hi there was no particular problem Just by tightening the nut on the valve And the problem was fixed very simply

The stopcok is fitted with theflow in the wrong direction remove the stop have a look at the stopcock for the flow direction insure when fitting it the stocok the flow direction is fitted in the correct direction

If your stopcock cuts off with a thud when you turn the water on to more than a trickle, it is possible that the gland nut or head gear joint needs to be adjusted. The gland nut is the nut that holds the valve in place, and the head gear joint is the seal between the valve and the stopcock body. If either of these is loose, it can cause the valve to vibrate and make a thud when it closes.

To adjust the gland nut, you will need a wrench. Tighten the gland nut until it is snug, but do not overtighten it, as this could damage the valve. To adjust the head gear joint, you will need to replace the O-ring. This is a simple task that can be done with a screwdriver.

If you have adjusted the gland nut and head gear joint and the stopcock is still making a thud, it is possible that there is a problem with the valve itself. In this case, you will need to replace the stopcock.

Here are some additional tips for troubleshooting a stopcock that is making a thud:

* Make sure that the stopcock is fully open. Sometimes, a stopcock that is not fully open will make a thud when it is closed.
* Make sure that the stopcock is not clogged with debris. Debris can prevent the valve from closing properly and can cause it to make a thud.
* Make sure that the stopcock is not corroded. Corrosion can damage the valve and cause it to make a thud.

If you have tried all of these troubleshooting tips and your stopcock is still making a thud, you should contact a plumber.

I hope this helps! Let me know if you have any other questions.

A stopcock is the mains valve that controls the flow of water into your property. You might also see it referred to as a stop tap. The stopcock is always switched “on” but you can turn it off if you have a leak in your home or if you need to carry out repairs, maintenance or home improvements.
