Outside Tap Installation

Outside tap installation gives you a safe, convenient water supply for gardens, cleaning and day to day outdoor tasks. The tap is fitted with proper isolation and backflow protection, with pipework routed neatly and checked for leaks so it works reliably in all seasons.

More information

What outside tap installation covers

A properly fitted outside tap should be easy to use, easy to isolate, and protected against contamination and weather. Installation typically includes:

  • Siting the tap for practical access, with a weatherproof finish
  • Connecting to a suitable internal cold water supply
  • Fitting an internal isolation valve so the tap can be turned off when needed
  • Adding backflow protection to help prevent dirty water entering the mains
  • Drilling and sealing the wall entry to reduce draughts and moisture ingress
  • Securing pipework and making good around the fitting where required
  • Pressure and leak testing before sign-off

Who this service is for

This service suits homeowners, landlords and small commercial sites that need reliable outdoor water access. Common reasons include watering gardens, washing cars, filling buckets, or supplying a hose for routine cleaning. It is also useful when an existing outside tap is poorly located, leaks, or has exposed pipework that is vulnerable to frost.

How installation is carried out

First, the best location is confirmed and the internal supply route is checked. The pipework is then run to the chosen position, the tap is mounted securely, and an isolation valve and backflow protection are fitted. Finally, the system is tested under pressure and the tap is checked for smooth operation and any leaks.

After installation

You will be shown where the isolation valve is and how to shut the outside supply off. If frost protection is recommended for your setup, guidance will be provided on winter shut-down and insulating any exposed sections. If you later add a hose reel or need a second tap, the existing setup can often be extended.

Frequently Asked Questions

Do I need an outside tap with an isolation valve and backflow protection?
Yes, these are important for safe and practical use. Isolation lets you shut off the outside supply quickly, and backflow protection helps prevent contaminated water flowing back into the indoor system.
Where can an outside tap be installed?
Most taps are fitted through an external wall near a kitchen, utility room or other suitable cold water supply. The best position depends on pipe access, the wall type, and how you will use the tap day to day.
Will the pipework be protected against frost?
The tap can be installed with sensible routing and protection to reduce frost risk. You will also be advised on isolating and draining the outside line during cold weather where needed.
Will an outside tap reduce water pressure inside the property?
A correctly installed tap should not affect indoor pressure during normal use. If you run the outside tap at the same time as other outlets, overall flow can drop, especially in properties with low mains pressure.
Can you replace or repair an existing outside tap instead of fitting a new one?
Yes, in many cases an existing outside tap can be repaired or replaced. If the current pipework is exposed, poorly supported, or lacks isolation and backflow protection, upgrading the setup is often the best long-term fix.
