Drainage Solutions

Some customers worry that water may collect at the bottom of the pit for their in-ground trampoline. The truth is that 99% of our customers have no problems with water. Although water may collect after heavy rain, it will quickly drain away. The exception is customers with non-porous soil, such as clay, where water drains much more slowly.

According to the diagram, a rock pit is a pit filled with a combination of rock, shingle or brick to help rainwater drain away. At the bottom of the pit you dig for the trampoline, dig a pit at the bottom about 600mm x 600mm x 600mm and fill the bottom with larger pieces of brick or rock and the top with smaller pieces.

All our in-ground trampolines come with full instructions on how to build a stone box. For further advice please contact our customer service team .

If you are concerned about drainage, the first consideration is whether you want to be proactive and arrange for drainage right when installing the trampoline.

The second option is to wait and see if you actually have a problem. The pit can be accessed after you have installed the trampoline – remove the edge guard and jumping mat. All of the options below can be done afterwards, so it is often best to wait and see.

That said – if you are worried or unsure about drainage, it is quick, easy and inexpensive to build a simple stone box at the bottom of the pit when you install the trampoline:

Here you use a simple drainage pump to pump water out of the trampoline when needed, for example when the pit fills with water after heavy rain. Connect a temporary power source to the pump (e.g. via an extension cord from the nearest outlet), plug in the pump, place the suction hose in the pit and route the discharge hose to another area of the garden. Then start the pump.

There are many pumps to choose from. Search Google for complete pump kits with all hoses and accessories. Contact us if you need help choosing the right one.

The idea here is that you place a 'submersible' pump at the bottom of the pit and connect it to a permanent electrical supply. You will need to dig a trench for the cable and outlet hose (see picture).

You can activate the connection either with a switch in the shed or house (depending on where you ran the cable) or with a float switch (shown in the picture). The float switch is activated when the water level rises and moves the switch to the vertical position, which starts the pump.

This is only possible if you can run a 100mm drainage pipe from the bottom of the pit to a lower point in the garden, such as a ditch.

This is a very good solution that works great. It is easy to install (see picture) and is not expensive – it provides security and does not require electricity.
