drip tape
 

Poly West on the Central Coast of California. They are used to selling to large scale farms so when i went in there and explained what i needed it for the guy was more than helpful.

I am now looking after a 2.6 acre charity garden, we are using drip line for irrigation but the cost here in BC is prohibitive. You have a link to these guys? I was unsuccessful searching :)

Here you go.

I finally talked my mom and stepdad into drip irrigation. I was installing their system today, and I noticed that the fittings are different now. The design of the fittings that attach to the header line through a punch hole now includes a threaded piece on the header line side that can be screwed down to tighten the fitting against the header line. It's a great improvement. Mine have always leaked.

Here is the old style:

The left side goes into the punched hole in the poly tubing that is the header line. That's where mine always leaked.

Here is the improved version:

Notice the threaded piece on the left. That screws down to hold the fitting tightly in the header line.

I'm going to replace all of mine next season with the improved style. It is a much better design.

the red one is the only one I have ever seen. that is on all of our drip tape. sometimes they are blue but the red ones are a better quality.

My grandparent's old stuff they gave me has the green ones. I ordered new fittings a few years ago, and they were orange and just as bad.
