Rated 5.0 out of 5.0 by Fast, Easy, Reliable Watering Systems Component We live in rural Western Washington State. Surprisingly, watering is necessary in the summer months and we need a flexible, easily maintained, easily changed watering system. The DIG poly tubing allows us to easily expand, contract, and modify our watering system. The 1/2 inch tubing delivers a volume of water sufficient to reach just about anywhere on our 3 acre parcel. Despite branching, adding new areas, and various other things that might tax its capability, the DIG tubing has never failed us. It is easy to install. If you can push two things together, you can use this highly flexible system. Adapters come in a wide range of types from 'L's to 'T's to adapters for splicing pieces and connecting garden hoses. Please refer to the attached photos to see how connectors can be used to branch lines to various areas. The connections depicted water 8 garden beds and 5 free standing trees - all from one garden hose feed. That's impressive by any standard. In the middle of this year's expansion of our system to some new garden beds, we had to leave on a research trip for our newest novel. There was no time to connect a permanent water line feed to the DIG tubing. As you can see in the photo, the quick solution of a hose end adapter worked very well. The gardens look great and are flourishing after our two week absence. DIG's tubing can be buried as still put up with significant foot and wheelbarrow traffic. It stands up well to winter cold and summer heat. Changing watering features is as simple as removing the unwanted 1/4 inch tubing, inserting a DIG 'goof' plug, and running the new 1/4 inch tubing to the desired place. It is so durable that parts of our watering system are made up of reclaimed and reused DIG 1/2 inch tubing. It's really that good. We swear by DIG 1/2 inch tubing. For reliability, durability, flexibility and - above all - value, you simply cannot beat DIG. July 3, 2013
Rated 5.0 out of 5.0 by Really good product The poly drip tubing was used to make artificial fish structure. And it worked perfectly, along with the Home Depot 5 gallon bucket and top. December 10, 2014

Rated 5.0 out of 5.0 by Saves A Ton On Water I'm using this drip tubing for my vegetable garden and it's saving me a ton on water. I like that you can direct the water to the roots of the plant. Here's a list of accessories that will work well in completing the installation of your drip system: 1/4 inch hole punch (to make holes in the tubing); 0-10 gph adjustable multi-stream dripper (emitters) so you can adjust the amount of water flowing to each plant and goof plugs (just in case you need to plug unwanted holes at a later date).

Rated 5.0 out of 5.0 by good stuff Been using this for years, just cannot buy in Arkansas, they never heard of irritation for gardens, well I only know of one other person who grow grapes that uses it. Great way to water and save money on water and tomatoes love being watered this way, and are healthier for it. March 5, 2013
Rated 4.0 out of 5.0 by Drip Drip Drip Got to save water people...Putting in a drip system in is the ticket. This feed line has what one will need. It is sturdy, flexible, and easy to work with. October 22, 2014
Rated 4.0 out of 5.0 by Excellent product This tubing is very versitile and easy to install. On my particular project I was forced to bury it just a couple of inches allowing it only to surface at each tree. Otherwise the rabbits will bite hiles in it in search of water. July 24, 2014
Rated 4.0 out of 5.0 by Good Purchase Good value when you have to cover a large area. You always cut shorter peices from the large roll. September 30, 2014
