FAQ - Using different water sources with your irrigation system

Learn how to use leaky Pipe on a Water Butt and with a rainwater tank.

Can I use LeakyPipe on a Water Butt?

Water Butts, if raised just a few feet higher than the area you intend to water, develop hardly any pressure.  For this reason you won’t find many products that will be reliable with this approach.
To make the most success with this, you will need to use a very porous pipe in short lengths. The LP12UH LeakyPipe is a very porous type that will work at very low pressures for short lengths (up to 20metres).

What If I want to use water from a stagnant lake or river?

The problem with this source is that it is invariably 'dirty' and heavy with particulate that needs to be filtered out of the flow, before the LeakyPipe becomes the filter!   Filtering on these sources can be both expensive relative to the size of use and inconvenient.
Again pumping will be required to create a pressure of 1-2 bar at the LeakyPipe for LP12H to work properly (less pressure is needed for higher porosity pipes, but fewer and shorter lengths of LeakyPipe can be watering at any one time).

What if I want to use a rainwater tank?

Fine to do this.  The water will need to be pressurized to give you 1-2bar working pressure at the LeakyPipe.  Keep the water in a light-free container (to avoid algae growth) and store as much as you can afford. Your stored water is invariably needed most during a drought, but rain water is least available at this time.  Therefore a mains top-up facility may be needed. Consider the capital investment in this (large tank and pump) compared to the variable cost of buying mains water and using it wisely.  It may be a better deal!
