What is a shutoff valve?

Question

Could you tell me what a shutoff valve is please? And how does it work? Any advice would be greatly appreciated.

Clifford · Answer

Shut off valves, could mean mains stopcock. Which would shut down the mains water supply coming into the property.
It could be a gate Vale going to or from the emersion heater. Or it could be an isolation valve directly next to a Basin, WC or Kitchen sink.

Normally for gas or water, if it’s for water it’s normally called a stop cock.
For gas, it could be called a shut-off valve.

Hi, a shutoff valve is an isolation valve that shuts off a water pipe in your property. Can be a main shut-off valve that obviously shuts the main water off, can be a shut-off valve for one appliance for example a tap, toilet, or bath.

Marc · Answer

It is a valve that you can isolate the water from traveling any further through the pipe.

Neil · Answer

A shut-off valve means exactly what it says really. A shut-off valve could be a gate valve a stopcock or a lever valve.
A shutoff valve isolates the water supply to a particular part of the plumbing system for example an outside tap. It can come in many different forms and depending on the type you have. 

Hope this helps and any more quires I would be happy to help .

Hi Jackie a shut off valve is just another name for an isolation valve, it's something that shuts or turns off the water temporarily.

Kind regards

A shut off valve is a loose term for any device that isolates the flow of a liquid or gas. Sometimes called isolating valves they can have a slot for a screwdriver to turn on/off sometimes a wheel (called gate valves) but the best in my opinion are lever valves as they  are less likely to sieze and really easy to operate without tools. Hope this helps.

A shut-off valve allows for any water to drain out at that point so maintenance can be carried out.
Hope this helps
Thanks, James

Scott · Answer

This is a stop tap. It can be the main stop tap to the house or it can be any isolating valve to an appliance or tap.

Jonathan · Answer

A shutoff valve is used to isolate (stop) any flow of water going past the point of the shutoff valve so Plumbers can work on pipework, taps, baths, cylinders, etc. Once work is completed u can open up the shutoff valve by the lever or sometimes a round spindle.

Shawn · Answer

It shuts the water off, there should be a stopcock under the sink or an isolator valve in the pipework to your tap.

David · Answer

In relation to water, it's like an on/off switch.
It's pretty simple to turn one way the water supply is stopped. Like turning off a tap.
Turn on water supply runs, like turning on a tap.
There are various valves that do the same job. The old-fashioned gate valve is found in airing cupboards.
The isolation valve.Near a toilet or under sinks.Opens and closes with a flat head screwdriver.
Then there is a stop cock on the incoming mains water.
So think of it as a tap but one-half turn shuts off.
Also, the term is used in oil, gas, and other manufacturing.
So I hope this helps.
David.
Plus central heating radiators have two valves that can be open and closed.
