Garden Water Supply Installation

A garden water supply installation gives you a safe, convenient external tap or feed to an outbuilding, without relying on temporary hoses or exposed pipework. The aim is a reliable outdoor supply with correct connections, isolation and protection against weather and frost.

More information

What the service covers

A practical, compliant installation designed for everyday outdoor use.

  • New external tap points for gardens, patios and driveways
  • Water feeds to sheds, garages and other outbuildings
  • External pipework routing and secure fixing (surface or discreet runs where possible)
  • Isolation valves so the supply can be shut off easily
  • Backflow protection where required
  • Leak checks and pressure testing on completion
  • Frost protection measures for exposed areas and vulnerable sections

Who this service is for

This service suits homeowners, landlords and small commercial sites that need dependable outdoor access to water.

Common reasons to book include:

  • You want an outdoor tap for gardening, washing down, or filling a pond
  • An existing outside tap leaks, is poorly positioned, or has unsafe pipework
  • You need a permanent supply to an outbuilding for a utility sink or equipment
  • You have repeated winter problems due to freezing external pipes

How the installation is carried out

The work starts with a quick assessment of the best route from the internal supply and the most sensible point to connect.

Typical steps include:

  • Confirming the supply source and checking water pressure
  • Agreeing the tap location and pipe route to minimise disruption
  • Installing the pipework and fittings, then securing and sealing entries
  • Adding isolation and protection, then testing for leaks and performance

After installation: keeping it reliable

You will be shown how to isolate the outdoor supply and what to do in colder weather.

If your setup is exposed, you may be advised on extra insulation or changes to reduce the risk of freezing, damage and unexpected leaks.

Frequently Asked Questions

Do I need an isolation valve for an outside tap?
In most cases, yes. An isolation valve lets you shut off the outdoor supply quickly for maintenance or winter protection. It also makes it easier to deal with leaks without turning off the whole property.
Can you run a water supply to a shed or garage?
Yes, a dedicated feed can be installed to an outbuilding for a tap or other cold-water use. The best route depends on distance, access, and whether pipework needs extra protection. You will be advised on the most robust option for year-round use.
How do you protect external pipework against frost?
Protection usually includes insulating vulnerable sections and choosing sensible routing to avoid exposed, unheated areas where possible. You may also be advised to isolate and drain down the line during very cold spells. The approach depends on how the pipework is installed and used.
Will the installation affect my water pressure indoors?
A correctly installed outdoor supply should not noticeably affect indoor pressure during normal use. If you plan to use high-demand equipment outdoors, the supply can be designed with that in mind. Pressure and flow can be checked before finalising the setup.
Can you replace or repair an existing outside tap and pipework?
Yes, existing external taps and damaged pipe runs can be repaired or replaced. This often includes improving the isolation, tidying exposed sections, and addressing leaks or corrosion. Where needed, the layout can be adjusted to reduce future issues.
