Lever valve as main indoor stopcock - Is this ok?

[DarrenThomas]

My kitchen has a length of (I think lead) pipe coming out of the concrete floor with an old stopcock on it. When the boiler was moved when we bought the place the installer couldn't shut the water off at the valve and so installed a lever type above it. No idea why he didn't remove it first.

I've had someone come to quote for a job who told me that if the house were to flood and we needed to claim the insurance company would say that the lever valve it's the wrong type and not pay out.

Fact or fiction?

I only ask as the other guy didn't mention it at all. So either one is not paying attention to my house or the other is lying/out of touch with new regs. As a custard I have no idea!

I was told on my water regs course that full bore 1/4 turn lever valves were now allowed under the regs.

What about backflow prevention? a decent stopcock has backflow prevention, a lever valve doesn't. just take off the lever valve and fit a new stopcock. And don't leave it fully open or it will seize up like the old one has, turn back a quarter turn to keep it free and gaive it a full turn every once in a while.

i was told and re told by the rep of the sure stop that you have to have a stopcock first then u can fit a lever valve afterwards. the rep for surestop said that the regs state there needs to be a stopcock before a surestop. but he did say weather it works or not is a different thing.

If Lead Water Pipe, inform Water Authority, as they could possibly replace this for you.

I believe that a few years ago, my late mother was advised to have it changed, and that this would be a Free Service from United Utilities.

This would surely solve you're Stopcock problem.

If a gas isolation valve has to be a lever valve i think it wouldn't matter if the water isolation valve is also a lever valve especially as gas is alot more harmfull. So long as the lever handle is turning downwards to stop gravity reopening the valve as they can sometimes work loose. I would still phone your insurance company to double check.

Perfectly fine as long as it falls to off. I fit em quite regularly for my elderly clients as they can easily isolate water in emergency..
Whack it with a walking stick etc

A stopcock does not have backflow prevention. A loose jumper stopcock will act as a sort of non return valve but it is not approved as one and should not be used as one. It is also not approed as a stop tap under the water regulations.

Modern Surestop valves are WRAS approved and can be used as a main isolation valve in a property because they now have a positive off function built into the body.

A bit of research has come up with this gem from Arrow valves tutorials on the water regs.

Under the old Byelaws, the “stopvalve” to a property was normally to BS1010 or BS5433. These are of the screw down type (with rising headworks), which incorporate a rubber washer. The new Regulations no longer specify a type of valve and spherical “Ball” valves may be used. R2.8 states that any valve may be used providing it confirms to an appropriate British Standard (e.g. BSI Kitemarked), or appropriate European standard, or the Regulator’s specification (e.g. WRAS / KIWA UK) and it is suitable for the purpose.

G2.8 makes it clear that spherical valves may be used for above and below ground applications. Indeed the valves supplied by the water company in the meter box are normally spherical.

G2.7 states stopvalves, servicing valves and drain taps “… do not incorporate a loose washer plate”. The reasons are not explained but are likely to be over concerns of unwanted non-return characteristics - where expansion from a water heater is acceptable for example. Loose washer plates have also been known to vibrate causing unwanted noise.

For further clarification have a look at Arrow Valves Ltd - Water Regulations and have a read of tutorial 9 wher the above quote came from.

Fitted hundreds in new build flats but also there is a stopcock prior to the lever valve .

Mike Jackson - pretty comprehensive answer there, well done mate.
