Full flow fittings are easy to use. Used in large and small garden irrigation systems.
We recommend 20mm pipe and fittings for small and medium-sized gardens.
To keep maintenance and repairs as simple as possible, keep to one size pipe throughout your garden.
For larger gardens and where pop-up sprinklers and high flow rates are required over pipe lengths further than 30m way from the mains water supply point , use 25mm pipe and fittings.
