fitting new stopcock

[Paul Cockhill]

Hi
I may need to replace a stopcock in a house because the clients are saying that the pressure is low. The water board have checked the pressure outside the house and it is good , however inside the pressure is low and I think the stopcock is stuck. It is on a metal pipe will this be difficult to change? I have only seen connections on plastic or copper before. Will most plumbers merchants supply these parts?
Any help gratefully received

Best thing to do is replace all of the water main ! you will find that the bore of the pipe as reduced due to corrosion just changing the stopcock wont help, and once you start messing around with old iron mains you will find yourself in a world of grief

can you turn the water off in the road, keep the body as it is and undo the rest and replace. Had similar thing before and thats how I dealt with it. I got pegler stopcock in my case which fitted.

As JTS said better replacing the whole main bore is gonna be severley restricted inside

HI

Thanks for your replies and I think you are right the pipe must be restricted and this could be the problem, so it might need replacing all the ironwork which would be a major job as it dissappears under the kitchen floor. Also the stopcock outside the property, on the road, serves two other houses but this is the first house before the main tees off to the other properties. Might be best left alone unless they want the whole thing dug up and replaced

easy enough to change that turn of out side chop through the valve with a angle grinder then couple of slots down wards and peel the bras of the thread below mi on the incoming bit and eiterher screw out of the next fitting upwards or cut it and use a philmac coupling
