Irrigation parts are of high quality and service was the same caliber. Frank G. I am installing a drip irrigation system to use on my deck to support our container plants. This will be an integral part of my system. Timer, check valve, "add-it" fertilizer injector, "Y" Filter, pressure regulator, 1/2" black poly tubing, then success!!! Jesse Johnson You guys are the best!! We have been using your drip irrigation products at our Food Pantry Garden for the past four years. Your dedication to customer service has set a very high bar that other companies could only hope to achieve. - Bart My favorite seller for garden irrigation: great products, prompt and courteous service.

Read more TOP 12 Outlet Dripper Manifold by DIG Outlet Flow Rate: Blank (No PC Drippers) Quantity Price/Each 1+ $5.90 $5.31 1 ADD __ Add To Project Add To Compare Product Files DIG TOP Manifold Instructions Product Description DIG's new TOP 12 outlet drip manifold has 1/2" FPT (female pipe thread) connection for easily converting a 1/2" sprinkler riser to drip irrigation. Delivering water directly to the plant through drip irrigation saves water by eliminating run-off and inefficiency from evaporation and wind drift. When purchased with the pressure compensating drip emitters installed, these will perform extremely accurate over a wide range of operating pressures -- 10 - 80 PSI. If you purchase just the manifold with no drippers (TOP-000) you will not have any regulated flow control, but these can be used with a variety of spray sticks, spray jets or micro-sprinklers. This application will require using the converter barb and 1/4" tubing. All other units come with 12 built-in individually pressure compensating drip emitters.
