For a neat installation in the garden, the control valves can be buried under the lawn or in a border, keeping all of the pipework out of sight.
A pressurised water supply is required to the valve box and a mains powered controller (not included) is needed to operate the 24v valves using low voltage, multi-core cable (not included).
Valve box dimensions 38cm x 25cm (lid) x 30cm high. Water Regulations stipulate that for above ground drip or sprinkler systems in domestic gardens, the irrigation system must be protected by a DB valve.
The master valve kit provides the DB valve, master solenoid valve and riser pipe.
