I have been using this and other DripWorks tubing for many years. I have never had to remove any because it stopped working.

This worked great for a landscaping project. Layed it between our new plants and placed it on a timer. Worked perfectly.
1/2 emitter tubing in our flower garden
By David L Foerster on 3/6/2014
We have over 300 feet of the 1/2" emitter tubing with 12" spacing in our flower garden. It does an excellent job watering our garden, and has been almost maintenance free. The best thing is all the watering time it saves for us!
Emitter Tubing
By Pat Hopkins on 3/6/2014
Purchased 400' of DET121-12in 1GPH 5 years ago. From the beginning the tubing never distributed enough water on the vegatable garden rows, Even running 3 hours a day 7 days a week, there would only be 6" diameter wet spots where the emitters were.. After 2 or 3 years the emitters plugged up with minerals deposits and even soaking the tubing in vinegar would not clear the emitters. Will replace with the Aqua-Traxx Drip Tape, which is 67% less expensive and has a 40 GPH flow rate.
Great emitter tubing
By Kevin Reidy on 3/6/2014
I've used this tubing for a number of years now adding more and more over the years. The 12' spced 1/2" tubing has performed extremely well in all of my xeriscape and is very easy to work with. When I expand more garden I'll go with this product.
