Fitting of an outside Tap does require quite a bit of steps to be followed. As most of the taps are fitted to domestic cold water under the sink. Connection of the tap by connecting it to a cold water pipe which does carry cold under- pressured water. So where can an outside Tap be fitted? Well, that’s pretty simple. Usually, outside taps can be fitted to any wall that has access to a water pipe in the house. The most commonplace for an outside tap is usually outside of the kitchen window since the sink is placed behind the wall, giving access to the main cold water pipe.
What are the Requirements for Installing an Outside Pipe
The requirements for installing an Outside Pipe are
1. The tap should be isolated by the stopcock or an in-line shut off valve or in-line service valve.
2. Double-check valve is fitted to prevent backflow of water due to negative water pressure.
3. Provision for the water to be drained from the pipework during the winter months and when the tap is not
4. The thermal insulation material is required for isolation from freeze prevention, these insulating materials
must be fitted around the external pipework.
How is Installing an Outside Pipe Done
1. Firstly plan out where is the tap required. Usually, it is ideal to place the tap be near the internal cold water
mains supply, this is done to reduce the amount of plumbing required. This can place such as the outside
wall behind the kitchen sink.
2. Now, as for the work inside the building, bring out the suitable places to do plumbing through the outside
wall and to make a connection to the cold water pipe. Such as directly under the tap to keep the pipe run
3. Now on inside wall, drill a hole through to the outside wall at the required position. Once you have a pilot
hole through to the outside drill it out.
4. Measure the thickness of the wall and cut a piece of copper pipe to length so that it can be inserted through
the wall to be a protective layer for the water pipe.
5. Inside the building:
o Turn off the water supply.
o Cut into the cold water supply pipe
o Fit a fitting to connect the new pipe.
o Along the new pipe-run, fit an service valve, then a double check-valve and a drain cock.
6. Run the pipe through the wall and fix it along the back-plate, fix the plate to the wall using wall plugs and
screws after the pipework has been cut to length.
7. After this, screw the outside tap into the back-plate elbow.
8. Before turning the water supply back on, check the fitting and tightening of the valves and all joints, close
the drain cock, the outside tap and the service valve.
9. Turn the water supply back on and check for leaks. Open the service valve and check for leaks. Open the
outside tap and check the flow of water. Close the outside tap and check for leaks.
10. After all these are done, finally, fit some insulation material around the pipework to protect from any
What is Backflow and why is it dangerous
In the world of Plumbing, Backflow is a term for an unwanted flow of water in the reverse direction. Sometimes due to pressure changes in the pipes water might flow backward and seep back into the main water supply line. This seeping back of water is called backflow. This happens when there is a break in the waterline of the pipeline. And sometimes this can result in a lot of contamination. Especially for public drinking water.
Thereby, according to the WRAS and Water Regulation double check valve must be fitted to prevent any contamination. It is highly recommended to install a double check valve inside of the building to protect the valve against the freeze and any damage. PLUMBISIMO plumbers are here to help you follow these requirements and

Legionella bacteria’s connection with Garden hose
Legionella bacteria is formed when stagnant water which is left inside the hose mixes with the increased water
temperature. This bacteria leads to serious type of pneumonia Legionnaires’ disease inside the human body.
Legionnaires’ disease basically starts when people inhale small water droplets contaminated with Legionella
pneumophila. Not only this, but the bacteria also cause another type of illness called Pontiac fever. Usually, the
bacteria requires the availability of stagnant water in between 20 to 45 degree Celsius to start its formation. As for the conditions inside the Garden hosepipe, turns out to be the perfect breeding spot for these type of bacteria.
