Construction plumbing

Complete water supply, drainage and sanitary installations for new buildings and major renovations — coordinated with your site team and tested before handover.

A plumbing partner from slab to handover

Plumbing mistakes on a building site are expensive because they get buried. A sleeve in the wrong place means core drilling through a cured slab; a drain laid without fall means breaking a finished floor.

We join projects early, check the drawings against the structure, and install with the inspection and maintenance of the finished building in mind. Developers, contractors and owners building their own homes all get the same documented process.

Six stages, each signed off

Every stage is inspected and recorded before the next one begins.

01

Drawings and coordination

We review plumbing, structural and architectural drawings, flag clashes with beams and ducts, and confirm sleeve and shaft positions before the concrete is poured.

02

Sleeves and embedded work

Sleeves, floor drains and embedded lines are placed and fixed before slab casting, with positions checked against the drawings.

03

Rough-in and first fix

Supply lines, drainage, vent stacks and risers are installed with proper support, fall and access points for future maintenance.

04

Pressure and flow testing

Supply lines are hydrostatically tested and held under pressure; drains are water- or air-tested. Results are recorded floor by floor.

05

Second fix and commissioning

Sanitaryware, taps, heaters and pumps are installed, the system is flushed, and every fixture is run and checked.

06

Handover documentation

You receive as-built markups, test records, valve locations and operating notes for pumps and tanks.

What we install

Water supply

Mains connection, underground and overhead tanks, lifting pumps, risers, floor distribution and fixture connections in PPR, CPVC or GI.

Drainage and vents

Soil, waste and vent stacks, floor traps, inspection pits and connections to the external drainage, laid with correct fall.

Rainwater

Roof outlets, rainwater downpipes and surface drainage that keeps water away from the structure and foundations.

Sanitary fittings

WCs, basins, showers, kitchen sinks and their concealed components installed to the manufacturer details.

Hot water

Water heater positions, hot and cold distribution and mixing arrangements planned for safe, even temperature.

Pumps and boosting

Transfer pumps, booster sets, pressure vessels and controls sized to the building height and occupancy.

Working with your site team

We report to the site engineer, keep to the programme, and leave each floor ready for the next trade. Daily progress and any clashes are flagged in writing, not discovered at handover.
