Working in Dorchester

We cover every part of Dorchester, including DT1, and nearby Weymouth (7.2 miles) and Yeovil (17.8 miles).

Dorchester gets the same process as anywhere else: a free survey at your home and a written, itemised quote. In Dorchester flats, any change to the WC or wastes is planned with the lease and the flat below in mind. If your Dorchester bathroom layout is changing, the soil stack position is checked first, because it decides where the WC can go.

Water across much of Dorset is 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

The WC connected to the soil stack, or a new branch where the WC is moving
Isolation valves on every fitting, so taps, cisterns and valves can be serviced without draining the system
Draining down and isolating supplies, with the rest of the house back on water as soon as possible
Shower pumps on gravity systems, and macerators or pumped wastes where gravity drainage cannot reach

Decisions to make first

Pipe routes

Drilling through the middle of joists, rather than notching the tops, keeps the floor strong. Routes are planned with the joist direction in mind.

Copper or plastic

Copper is rigid and suits pipes on show or near the boiler. Plastic is quicker under floors and inside walls, and long runs need fewer joints.

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.

Who handles building control for bathroom plumbing work in Dorchester?

What is the maximum flush for a new toilet?

A new WC must have a maximum flush of 6 litres under the water fittings rules in England, Wales, Scotland and Northern Ireland. Dual-flush WCs add a smaller flush, often around 4 litres or less, for liquids. Our hard water guide covers keeping valves and cisterns working in scale-prone areas.
