Lawn Sprinkler Installation
In today's plumbing series tutorial I show you how to design and build an expandable zoned lawn sprinkler system.
An open sprinkler box containing the manifold with three zone valves. Orbit unions where used to attach a pre-built manifold to each of the three Irritrol 2400TF sprinkler zone valves and also to the supply pipe and temporarily to an elbow that attaches to a pressure gauge. I also added a ball valve to shut off water supply to the manifold and another to isolate the quick connect for the air compressor blowout connection.
Note the absence of a vacuum breaker - these are almost certain to cause problems in Colorado in the Spring and Fall, when temperatures drop from above 80F to below freezing, sometimes in a matter of hours. To prevent backflow, I'll be adding an RPZ device in the basement, instead.
