Use Teflon tape to make watertight connections between components with pipe threads and o-rings or hose washers with components with hose threads. Hand tighten each part to make a water tight seal. Be sure not to over tighten any hose thread connections, over tightening can cause the threads to strip and become damaged.
Irrigation Valves: For an above ground installation, start with installing anti-siphon valves. An anti-siphon valve combines a valve and vacuum breaker in one device, so there is no need to install a separate vacuum breaker. On the downstream of the valve, you will need to install a filter, pressure regulator and hose tubing adapter. These parts can be installed just below the valves outlet or in a valve box for access to the filter.
Inline valves need to be installed in conjunction with a back flow preventer. Back flow preventers are larger versions of the vacuum breaker and are mainly installed and large residential or commercial installations. Check with your local municipality for any code requirements concerning the use of backflow preventers. Inline valves will require a filter, pressure regulator and tubing adapter. Irrigation Direct offers preassembled drip zone kits.
