Connecting Main water line to water tank in Gravity Fed Drip Irrigation In this on Gravity fed Drip Irrigation system we will show you how to make connection between main water line and water tank using Grommet and connectors we will be using a gate value to stop and start main water line from water tank from this value we will connect water line going to different lines of plants Now we will drill a 16 mm hole to fix Grommet in the water tank using a 16 mm Hole drill bit using a electrical drill. The grommet will ensure leak proof connection of water pipe to tank ok now we will make a 16 mm hole in water tank we will drill hole 1 inch above the base of water tank to avoid dust getting into the drip irrigation system One big problem faced in Drip Irrigation is choking of Emitters by dust particles If there is any dust particles in the water tank they will settle in bottom and drip system will get clean water which will not clog the Emitters Now we attempt to drill hole in water tank hole got drilled rather easily and I do not know if it is sharp drill or weak drum Now next step is to fix Grommet in the water tank we will push the small side of Grommet first into the water tank Now Grommet is properly fitted to water tank after little adjustment from inside of tank Now we will connect 16 mm connector to grommet to which main water line will be connected In next video will check and install working model of Drip Irrigation Camera Panasonic DMC TZ30
