A solenoid valve is the automatic tap that controls that flow of water to an irrigation zone. Solenoid Valves are automatically operated by an irrigation controller which is programmed to tell the solenoid valve when to open & close.
The number of solenoid valves you use depends on the size of your garden & the flow output of your water supply. The number of litres per minute that are available will determine the number of sprinklers or drippers you can operate at any one time. Once your garden is divided up into each section using that information, you’ll need one solenoid valve to operate each one individually.
A master valve is installed upstream of the solenoid valves being used to control each irrigation zone. They’re not mandatory, but they are a good idea as installing one increases the life-span of each valve by protect the valves downstream from the constant pressure that would otherwise be applied. The way it works is, every time a zone is programmed to come on the master valve also switches on, providing the flow, but when all the zones are off, the master valve closes, holding back the flow & pressure of the water supply. Simply, it’s kind of like an irrigation insurance policy.
Being exposed to the weather, water damage will occur any where water can get in. Electrical tape isn’t quite water tight & over time water will creep into the circuit & create havoc & void all warranties. For this reason you should always use waterproof cable joins like heat shrinks.
Nearly all of the time, a solenoid valve staying open is caused by debris caught in the diaphragm. Even the finest debris can cause the valve not to seal shut, causing a constant leak. Other cause can be: Not enough flow because the irrigation zone is too small or, not enough pressure, the valve needs the pressure to seal shut.
Unless your tank located is upwards of 20m above your valves, gravity feed will not provide enough pressure for your valves to reliably open & close. It is not recommended.

Whenever you’re connecting two threaded fittings, teflon is required. The only exception is whenever either fitting has an O-ring, in this case, do not apply teflon as it may cause the O-ring to not seal correctly. The amount of teflon you apply depends on the application. In any constant pressure applications you look at up to wrapping around the thread up to 20 times, whereas in any non-constant pressure applications, like on irrigation risers, 2 or 3 times around the thread is enough.
Unfortunately, this is one of the hardest tasks in irrigation. First, look in the obvious spots which are near you water connection & any garden taps. Often over time solenoid valves can get buried, so it can be useful to use a stick or long screwdriver to poke prospective areas until you feel that hard tap of the valve box (if there is one). Beyond that, it’s time to consider solenoid valve seeking equipment or calling a serviceman. This can all be avoided of course by installing valves in single locations on a manifold close to a tap & at a depth not likely to get covered over time.
