Sub Surface Drip Irrigation - Drainage Valve
Component Assembly For Sub Surface Drip Irrigation Systems
Continuing with our Drip Zone Assembly we will now look at the components required for the Drainage Valve.
Zone Drainage Installation and Assembly
Sub Surface Drip Irrigation zones need to be drained for winterization and periodic flushing of the line to ensure worry free operation, depending on the quality of water being used and proper filtration.
Location: Zone Drainage should be located at the lowest point of the Drip Zone and can be housed in a small valve box (optional). The zone drain valve is to simply turn on manually and the most of the water will likely flow out naturally. For winterization, depending on the size of the zone and system, nothing more than a shop vac will be needed to completely drain the lines. If using a small valve box to house the zone drainage it is often recommended to put a small bedding of gravel at the base of the box for a tidy area and to avoid clogging with mud.
Zone Drainage Installation Component Options
It is relatively simple to install zone drainage, with the only variable being the size of tubing used to go from the exhaust header to the zone drain. The drain line will either be a piece of tubing used for the Headers or a small piece of Drip Line. We have illustrated a few option below.
This concludes our tutorial for sub surface turf irrigation using drip emitter tubing.
