Our Working Process

1.      Consultation: we discuss the issue you are having and which taps or valves need attention.

2.      Site visit: our team inspects the fixture in person rather than guessing from a description.

3.      Inspection of existing tap or valve: we check the current fitting for wear, corrosion, and damage.

4.      Leak assessment: we identify exactly where water is escaping and why.

5.      Selection of compatible replacement: we choose a new tap or valve that fits your existing plumbing and usage needs.

6.      Water supply shut off: the relevant water line is shut off before any work begins, coordinated with our Water Supply Line Installation team on larger jobs.

7.      Removal of old tap or valve: the worn component is removed carefully to avoid damaging surrounding fittings.

8.      Installation of new component: the new tap or valve is fitted and properly aligned.

9.      Joint sealing and tightening: connections are sealed and tightened to the correct specification.

10.   Water flow testing: the water supply is restored and flow is tested at the fixture.

11.   Leak inspection: we check closely for any sign of leakage under normal water pressure.

12.   Final quality check: a full review to confirm the replacement is working properly.

13.   Project handover: you get a fully functioning tap or valve and a clear explanation of the work done.

Components & Options

Not every tap or valve fails for the same reason, so we match the replacement to what the fixture actually needs to handle.

•     Kitchen taps: see more daily use than almost any other fixture, so washers and cartridges wear out faster here than anywhere else.

•     Bathroom taps: face more moisture exposure and mineral buildup from standing water.

•     Mixer taps: blend hot and cold water through a single spout, and it is usually the internal cartridge that fails rather than the whole unit.

•     Bib cocks: are simple, single direction taps found at outdoor points and utility areas, where a drip is easy to ignore until the water bill catches up.

•     Angle valves: control supply to individual fixtures and are built to be turned rarely, so they usually fail from age and corrosion.

•     Ball valves: give full, clean on and off control and are commonly used at main shut off points.

•     Gate valves: regulate flow across larger pipe sections and can seize up if left unused for long periods.

•     Flush valves: control water release in toilet systems and are one of our more common replacement calls.

Benefits of Choosing Our Service

•     Leak free plumbing: at every connection.

•     Better water pressure: at the fixture.

•     Longer plumbing lifespan: overall.

•     Lower maintenance costs: over time.

•     Prevention of water damage: from slow, hidden leaks.

•     Added property value: from updated fixtures.

Common Problems We Solve

•     Constant dripping taps

•     Leaking valves

•     Rusted or corroded fittings

•     Broken tap handles

•     Loose tap installation

•     Low water pressure at specific fixtures

•     Faulty mixer taps

•     Valves that will not close properly

•     Water leakage around fittings

•     Old plumbing fixtures needing replacement during renovation

Choosing the Right Tap or Valve

•     Kitchens: need taps built for frequent use and some exposure to grease and food debris, so a solid cartridge matters more than the finish.

•     Bathrooms: call for corrosion resistance and a comfortable handle design, especially in humid conditions.

•     Outdoor installations: need fittings that can handle temperature swings and occasional neglect.

•     Commercial buildings: including hotels, restaurants, and offices, need fittings built for heavier daily use across multiple bathrooms and kitchens.

Budget matters, and not every tap needs to be a premium designer piece. It is worth spending a little more on fittings that get used constantly, like kitchen and bathroom taps, and saving on ones used occasionally, like an outdoor bib cock. Material quality, actual water pressure, finish, and compatibility with your existing plumbing are all worth weighing too.

Frequently Asked Questions

When should I replace a tap instead of repairing it?

If a tap has already been repaired once or twice without lasting, shows visible corrosion, or has a cracked handle or body, replacement usually makes more sense than another repair.

What are the signs of a faulty plumbing valve?

Common signs include a valve that will not fully open or close, visible leaking around the valve body, corrosion, or reduced water flow even when the valve is fully open.

How long does tap replacement take?

A standard tap or valve replacement usually takes under an hour once the site visit and part selection are done. Multiple replacements or more complex plumbing take longer.

What causes taps to leak continuously?

Continuous leaking is usually caused by a worn washer, a failing cartridge, or corrosion inside the tap body. Once these parts wear down, tightening the tap further will not stop the leak.

Can you replace the main water shut off valve?

Yes. We replace main shut off valves as well as smaller angle and gate valves throughout a property, with the water supply properly shut off before any work begins.
