Working in Keynsham

We cover every part of Keynsham, including BS31, and nearby Kingswood (2.7 miles) and Mangotsfield (5.1 miles).

Keynsham gets the same process as anywhere else: a free survey at your home and a written, itemised quote. In Keynsham flats, any change to the WC or wastes is planned with the lease and the flat below in mind. If your Keynsham home has a gravity system with a loft tank, we check the head of water before recommending a shower or a pump.

Supplies across most of Somerset are hard. Taps, plug wastes and toilet pans scale up quickly, so chrome copes better than matt black, and a removable aerator is worth having. Hardness varies street by street, so check the figure for your postcode with your water supplier.

What the job includes

A pressure test of new pipework before walls are closed in and floors go down
A check of your hot water system, and the pressure and flow rate at the bathroom
Shower pumps on gravity systems, and macerators or pumped wastes where gravity drainage cannot reach
The WC connected to the soil stack, or a new branch where the WC is moving

Decisions to make first

Concealed or exposed valves

Concealed shower valves look neater but need an access route for servicing. Exposed bar valves are easier to reach and replace.

Shower supply

Combi boilers and unvented cylinders give mains pressure. A gravity system with a cold tank may need a pump, but a pump must never be connected to the mains.

Rules that apply in England

In England, the Water Supply (Water Fittings) Regulations 1999 apply. New drainage or a new connection to the soil stack can be building regulations work under Part H, and a macerator or pumped WC is acceptable only where there is also a WC on gravity drainage elsewhere in the home.

Is the water hard in Keynsham?

Who handles building control for bathroom plumbing work in Keynsham?

Building control for Keynsham is handled by the local council or an approved inspector. If your job needs sign-off — for example a new circuit, new drainage or a new extractor where there was none — we tell you at the survey and handle the notification as part of the work.

Do I need isolation valves on bathroom fittings?

They are good practice on every fitting. An isolation valve on each tap, cistern and shower supply lets that fitting be repaired or replaced without draining the system or turning off the whole house. We fit them on new bathroom plumbing as a matter of course.
