Use an Isolating valve as a main stop valve?

[Theo]

First post for me!

I am refitting the kitchen in our house and want to make things a neat as possible.

I am wondering If I can use one of those neat isolating ball valves with a screwdriver slot as the main stop valve for the house supply. There is an accessible stop tap outside under an inspection cover.

TIA

You can but I would not advise it get a 1/4 turn lever valve, and do not forget to put a drain off cock above

welcome,


as migo says.




ball valves are not really that reliable, especially when you need to turn of after a few years and it is seized.

I know ,why not just use a stopcock,nice and easy to open and close when needed quickly
As said ball a fix will get chewed up and stop turning after a few years and start leaking
Some times when we are putting kitchens and bathrooms in we can get a bit carried away,trying to make things as neat as possible ,once in the back of a cupboard,with every thing piled infront,you will never notice it

Use a brass stopcock.

In any case, the isolating valves are often reduced bore and can reduce water flow to the house.

and can cause system noise too.

dont forget wras states you have to use a stopcock as it has a loose jumper to prevent back siphonage into the mains if mains pressure drops, forget ball valves etc

Yep thats as i understood it. Was advised if stopcock broken or letting by either replace with same or fit 1/4 turn lever above it but stopcock must remain.

beat me to it but as above Stop tap (including drain valve) is required.
