Discuss Can i use a ball lever as mains stopcock in the Plumbing Jobs | The Job-board area at PlumbersForums.net
Hi,
Is it OK to use a ball lever as a mains stopcock? ive read a few old threads but none of them seem to have definitive answer! also can you use plastic / push fit off a mains stopcock or does it have to be copper?
Why do you want to use a lever valve? If it’s because they are easier to turn for the elderly, then I would install a surestop if it’s possible.
No you can’t water board dont like you using them so they could make you change it
Nah , they dont own the stoptap .
Personally I think they think down the lines of the “lever arms” have not been around to “stand the test of time “ .
See attached photo. They don’t own the stoptap but they are responsible for enforcing the water regulations and may legally ask for it to be removed if they are not happy with the fitting if it contravenes the regulations.

Quite right Jon. Oh and telling them to remove it would directly contravene their mandate so they waste water! Bl00dy rules!Unless the full link isnt working and there’s something else , it says Yes !!
I would love to see the waterboard tell some of my customers their lever arm is coming out !!
I have spent years telling and training them to turn off their water when they go away , they love em and use them because its easy . Go back to stop taps and they wouldn’t bother lol .
I have fitted a few, including 2 for elderly home owners who have had no trouble in using them. Depends how able you are, at the end of the day.Having installed many surestops many elderly still do not have the strength to operate them. A lever is pulled about the moment of closure and is a sphere. A surestop takes great 'point' pressure from a thumb which many just can't do. Sorry, BYP but I'm a pragmatist
Exactly this, I personally don’t see an issue.All current BS1010 stopcocks, are fixed jumper.
So no backflow protection.
There is no requirement for this at point of entry to a property... just means of isolation with a DoC immediately downstream.
& Stop cocks are not cocks they are valves .Lever valves are not stop cocks.
Show me where it states that, so your double checks only protect against Cat 3 what happens if you had a Cat 5 ??If you use a lever valve you will need to install a backflow prevention valve downstream of the lever valve.
Exactly, we protect the mains at point of use not point of entry. Airgaps at taps, non-return valves at unvented cylinders, air gaps on CWSC, same with toilet cisterns, filling loops with double check and detachable linking hose. Rarely is "Whole site protection" needed via the main.& Stop cocks are not cocks they are valves .

I really should stop posting late at night!the shock waves can cause fittings to come off.

In the course of my investigations, I have come across about this. I know that others have already explained this and I wish to add the details that I also found as further information.The question regards a plumbing valve with 'stop' incorporated.
From my experience 'Stop' means - non return valve.
A valve with a loose washer, that will seal 'techinally' to prevent backflow.
Most of our water meter valves are 1/4 turn, hence the requirement for a dual check backflow valve.
This is to prevent the water from a property entering the mains, if the mains are switched off for any reason.
Not sure what Cat 3 & Cat 5 are.
Q. WHEN DO I NEED TO INSTALL WHOLESITE PROTECTION?
The Water Supply (Water Fittings) Regulations and Scottish Water Byelaws only specify two situations where wholesite protection may be required or considered necessary.
1. To prevent backflow between separately occupied premises, an example could be in blocks of flats or other buildings of multipleoccupancy such industrial units or shopping arcade.
2. A water supplier may consider additional protection is needed for the whole or part of buildings where there is an increased risk of backflow occurring.
Your local water supplier is best placed to advise on the situations which may require additional protection.
Backflow protection is not required in a normal domestic house at the point of entry, point of use protection is required. In multi occupancy properties with a single rising main where backflow could occur from higher to lower properties protection is required at all but the lowest property.
Although a loose jumper stop tap will function as a primitive back check valve it is not recognised as such within the water regulations.
OZ, can I humbly suggest that as a practising Plumber (if in the UK), you book yourself onto a Water Regulation training course asap.The question regards a plumbing valve with 'stop' incorporated.

As you maybe confusing others seeking info on back flow issue.
Then why post if you are not sure of UK Regs ???hes from down under
