You better of turn water from street and change the head of the valve but keep body in , this is possible if a your old stopcock is not the one that is fitted to lead pipes
post a picture and I can advise you what to do

The way I read the fact sheet, ball valves are permitted, but backflow protection is also required. Therefore a separate checkvalve needs to be fitted, if a ball valve is used.

I mention this as I was hoping to replace my old stopcock with ball valve without having to change any pipework. No such luck.

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.

Thanks for offering, but it's done. I just replaced with the same type with the flow direction arrow on the side.

All sorted for another 30 yrs, till I snap the handle off again.
