Both figures describe the Bolton council area. Bury's districts, BL0, BL8 and BL9, are covered all the same, though the figures above do not count them.
Should water start coming through a ceiling from the home above, Citizens Advice says a neighbour who caused the leak through carelessness, by leaving a bath to overflow for example, pays for the damaged belongings, and the page on who pays when a leak damages the flat below sits with the pipe leak pages.
Which sources feed Bolton's water supply?
Bolton's water supply is fed from the Lake District and from local reservoirs, United Utilities' water quality checker says for the town centre, while Halliwell and Breightmet are supplied from local reservoirs and Westhoughton and Horwich from the Lake District.
Treatment happens close by: United Utilities describes Sweetloves water treatment works as the works “which supplies drinking water to the town”. Bury is United Utilities' patch as well, inside the area it describes as including Greater Manchester.
United Utilities' network runs up to the boundary of each property. Past that line the supply pipe belongs to the owner, and finding a leak on it under a garden or drive is the job of underground water leak detection.
Which leaks are traced in Bolton homes?
Bolton homes see four kinds of leak traced: water lost from a central heating circuit, a leaking pipe in a wall, floor or ceiling, a leak along the buried supply pipe, and the source of escaping water behind an insurance claim.
- When the pressure needle sinks again between top-ups, central heating leak detection finds the point where the heating lets its water out.
- Under a ground floor, as the page's opening drawing shows, the incoming pipe can leak out of sight on its way to the stop tap, and pipe leak detection locates that point first.
- Between the boundary and the front wall, the buried supply pipe is the owner's length, checked with acoustic listening, tracer gas and a pressure test.
- For an escape of water claim, the leak behind it is found and its position written down, a search that many policies fund through their trace and access section.
When is a Bolton leak United Utilities' job?
United Utilities deals with a Bolton leak when the water is escaping from its main, from the communication pipe between the main and the boundary, or from the external stop tap in the footpath; the owner deals with the supply pipe from the boundary inwards and every pipe indoors.
United Utilities: the main in the road, the communication pipe to the boundary, the external stop tap in the footpath
The owner: the supply pipe from the boundary, the internal stop tap and every pipe indoors
United Utilities' Report a problem page takes reports of leaks in the street, on the main and at the external stop tap. For the owner's own length, its Leaking supply pipe page sets out what to do, and it says that in a rented home the landlord is the one responsible for repairing the leak.
Bury works the same way, since United Utilities supplies it too, and the guide to leak detection across the North West brings the four investigations together.
