Working in Watford

We work right across Watford — WD1, WD17, WD18 and 2 more postcode districts — and in neighbouring Bushey and North Watford.

Watford has a wide mix of house ages, so the survey is where we spot old lead pipework, weak joists or a tight soil stack. If your Watford bathroom layout is changing, the soil stack position is checked first, because it decides where the WC can go. For Watford homes on a combi boiler, we measure the flow rate at the bathroom before you choose a shower valve.

Most of Hertfordshire has very hard water. 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

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
New hot and cold pipework in copper or plastic, properly clipped, and insulated where it runs through cold spaces
A pressure test of new pipework before walls are closed in and floors go down

Decisions to make first

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.

Hard water

In hard water areas, a scale reducer or water softener protects valves, shower heads and glass. Keep an unsoftened tap in the kitchen for drinking.

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.

What is the price of bathroom plumbing work in Watford?

Is the water hard in Watford?

Who handles building control for bathroom plumbing work in Watford?

Building control for Watford 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.

Can a toilet be moved anywhere in a bathroom?

Not anywhere. A WC needs a 110 mm waste with enough fall to reach the soil stack, and the joists limit which way that pipe can run under the floor. Where gravity drainage cannot work, a macerator is an option only if the home also has a WC on gravity drainage.
