With a water connection in the garden, exhausting lugging around of watering cans finally comes to an end. In any case, the supply line to the pond, stream and paddling pool becomes child's play if you no longer have to laboriously maneuver meter-long hoses in the garden. These instructions explain step by step how to set up a water tap yourself.

The experienced craftsman can lay the water connection in the garden himself

Material requirements and tools - This is what is needed

Thanks to modern cold water pipes made of plastic, laying a water pipe in the garden is not reserved for experienced plumbers. Connection work up to the meter is reserved for the regional waterworks. Behind it, do-it-yourselfers can of course get to work themselves to install a water connection in the garden. The following materials and tools are required:

  • Cold water system with 32 mm polyethylene HDPE pipes including accessories
  • sand, grit
  • paving slab
  • wooden boards
  • Post shoe with screws
  • Teflon tape
  • Pipe snips or fine hand saw
  • drilling machine
  • file
  • spade
  • wheelbarrow

Competent suppliers of cold water systems provide calculators for the material on their websites. Once the length of the supply lines has been determined, all the required couplings, T-pieces, elbows and screw connections are included in the scope of delivery. Therefore, please create a precise plan that includes all locations where water should be available in the garden.

Please note that these are only pipes for a cold water system in the garden. Temperatures must not exceed 20 degrees Celsius. The maximum pressure is 12.5 bar.

Preparatory work - let's go

Plastic pipes made of high-density PE-HD for underground laying are available from the trade as coils up to 50 meters in length. Unroll the flexible pipe in the garden according to your sketch and weigh it down with stones. At the measured junction from the main pipe to the tapping point, place the fittings and other parts as well as the pipe cutter on the ground within easy reach.

In contrast to house connections, water connection pipes in the garden do not have to be laid at a frost-free depth of 80 to 100 cm. It is therefore sufficient to dig a 30 to 35 cm deep trench for the plastic pipes. Fill in fine sand halfway up to prevent stones from damaging the pipes. Lay the main pipe in the trench, but only fill it in after you have made a pressure test to ensure that no water is leaking.

Installing a water connection - this is how it works

Measure the exact distance at the junction from the main pipe to the tap. Please also use a pipe with a diameter of 32 mm for this supply line, so that a sufficient amount of water can always flow through. Then dig a 30 to 35 cm deep trench, which in turn is half filled with sand. How to proceed:

  • Cut through the PE main pipe at the measured point with pipe cutters or a saw
  • Smooth the cut with the file to prevent damage to the rubber seals
  • Slide the union nut, clamping ring and O-ring onto the line
  • Connect pipe, fittings and union nut and tighten hand-tight

Finally, the main line and branch are connected using screw fittings and union nuts. So that everything is tight, please make sure that you first push in the molded part of the screw connection to the second stop before you tighten the union nut.

Connecting and designing a water tap - tips & tricks

The chilled water system comes with a matching dispenser tube that you connect to the end of the branch line. We recommend a pavement slab as the base for the pump, in the center of which you drill a hole for the pipe to pass through. After the one pressure test, fill the trench with sand and grit (€46.95) as a base for the concrete slab.

Ideally, a post shoe gives the dispenser pipe additional stability. A wooden board acts as the back wall for the water tap, screwed to the post shoe with carriage bolts. Attach the connection piece for the water tap to the back wall at hip height with stainless steel screws and connect it to the dispenser pipe using an angle. Please do not seal the thread on the bracket with hemp, but with Teflon tape.

In the last step, you make the connection between the water tap and the connection piece, carefully sealing it with Teflon tape. If you clad the water tap all around with wood, the back panel is doubled so that the wall panel for the water tap is located directly behind the front panel. Use a hole saw to create the opening to connect the faucet and connector.

Tips for connecting to the house connection

The water can only flow when the water connection in the garden is connected to the public supply network. In modern new buildings, there is usually already a plastic pipe for the house connection in the ground. With a T-piece, the connection is made in no time at all.

If you want a connection to the garden pump or a deep well, specialist retailers have practical solutions ready. This also applies to the transition to narrow copper lines in older houses using screw connections, adapters and couplings.

tips

Do you use your water connection in the garden for irrigation and the supply line to the pond and various water features? Then we recommend the additional installation of a garden water meter at the tap. This way you can save on sewage fees.
