Drip Zone Head Assembly
Drip irrigation water connections start at the water source with what is called the “drip zone head assembly”. The drip zone head assembly can be attached to a faucet or valve (manual or automatic) such as an anti-siphon valve or inline valve and can be installed on many zones or sections. The head assembly consists of vital components that include a filter and a pressure regulator. The filter protects the water passages of the drip emitters, dripline and micro sprinklers from clogging, and the pressure regulator (installed after the filter) reduces the incoming pressure to the appropriate operating pressure range used for drip systems. Start your drip irrigation or micro sprinkler system by selecting individual components to create a customized drip zone head assembly, or use one of DIG’s completely drip zone head assembly.
