How We Carry Out Work
-
1
Mains supply verification
We confirm external shut-off operation at the boundary box before breaking into the indoor pipework.
-
2
Component removal
The failed stopcock is uncoupled from copper, lead, or MDPE pipe using dedicated transitional fittings.
-
3
Fitting and sealing
The replacement valve is mechanically secured with copper compression olives or compression adaptors.
-
4
Pressure check
Water is reinstated gradually, followed by a ten-minute dry-wipe inspection to confirm zero weeping.
Questions about this service
What happens if the outside street valve cannot be turned off?
If the boundary box street valve is seized or buried, we apply mechanical pipe-freezing equipment to the incoming pipe indoors to execute the change without flooding.
Can you fit a quarter-turn lever valve instead of a traditional round wheel?
Yes, we stock both BS 1010 crutch-head screwdown valves and quarter-turn full-bore brass lever ball valves, subject to space inside your cupboard or void.
Do you reconnect lead incoming mains pipes?
We carry mechanical lead-to-copper compression couplings to connect modern valves to existing 3/8-inch, 1/2-inch, or 3/4-inch heavy lead pipe.
