Customer Questions & Answers

will tis work with a gravity feed from a rain barrel?

Asked by: TCStevieD
No, the dripline needs at least 10 psi to function properly.

Can this be buried

Can this system be placed underground or with the roots block the emitters?
Asked by: WildBill
Hi WildBill, - Standard installation of a drip emitter line is to place it on top of the weed preventer mesh and then cover it with mulch. The malfunctioning emitters tend to be the #1 problem in drip irrigation installations. If you place them underground it is difficult to detect a problem and repair it. Since they should be covered with mulch to shelter them from heat and limit evaporation, there is no visual reason to place them underground. Drip irrigation systems have to be winterized and of course will not function correctly if it freezes. They have to be drained of water to prevent damaging the tubing. The further south you live gives you more options. If you use a thick enough layer of mulch you can lengthen the time you can use the system but hard freezes endanger the system and can do significant damage. I use an air compressor to clear the lines of water before a freeze. It works just as long as you use a regulator valve to hold the air pressure at or below the water pressure normally used in the system. Higher pressure can pop out the emitters and damage the emitter holes and in the extreme split the tubing. Caution when buying drip irrigation supplies as the fittings can be different sizes between different brands. You can end up with a pile of fittings that you can't use. Hope that this helps. DJK

can I connect this to sprinkle system?

I would like to take one head of sprinkle system and use this tubing to put on. Do I have to do it with all heads to get proper flow? The guy at home depot offer me 1/4inch tubing, but didn't warm me about pressure. Thank ou.
Asked by: Pegyna
no it is not recommended to do that unless all of the spray heads are capped.

I have 1/2" drip line (black) and 1/2" porous tubing (brown) and need to connect them

Hi, I have an area where I need some drip lines run from 1/2" black drip line, and then transitions to an area where a porous tubing is more efficient. Is there a way to connect the two of those? I have a 'T' I though would work but I cannot get the black tubing to insert into the connector. The reason I have a 'T' connector is because I have basically created a circle out of the soaker to water that area. Was going to connect the 1/2" black drip line to that and then run drips to the various plants in that area.

Repairing and connecting 1/2" I.D. drip line hose can be challenging. I finally discovered that the plastic quick-connect fittings (male and female) that Home Depot sells for garden hose (see and happen to have the correct O.D. to slip into the 1/2" tubing. You'll have to use screw-type hose clams to make sure the adapters are held in place (Home Depot sells them individually or in small bags in the plumbing department). The rubber "o-ring" on the fittings help keep the connections water-tight. I use plastic caps on the ends of my drip lines ( The big drawback is that the plastic fittings have a small I.D. which restricts the water flow somewhat. This summer I'll be running eight (8) fifty (50) foot lengths of 1/2" porous irrigation tubing for my raspberries. I've been told that this hose is designed for 25 psi, so I'm installing a water filter, a pressure reducer, and eight timers (one per row) so that only one row gets watered at a time. This should alleviate problems such as under-watering some rows while over-watering others.

1/2 in. x 100 ft.1 GPH Pressure Compensating Drip Line is rated 3.9 out of 5 by 23.
Rated 5 out of 5 by from I have used this dripline for several years and I... I have used this dripline for several years and I am very pleased with the performance. It is easy to install and maintenace free. If possible install in warm weather and let the tubing warm up on a straight line to make installation even easier.

Rated 5 out of 5 by from install and forget I've first noticed this product (the black one) installed by house builders 16 years ago, and the drip line is still working to this very day, that was from our very first house bought. I've customized many drip emitters with the regular tubing, and always, within a year, there would be some unplugged emitters, geyser leaks and some plants dying because of upstream leaks from regular emitter system while wasting water. The dripline with built-in PC drip emitters behave like a soaker tube, only without the clogs. They reliably deliver without clogging. You spread the tube uniformly, then the ground is wet uniformly. I usually bury them at 4" deep for my trees, and then no grasses germinate all summer long. For the veggie garden, the 18" spacing is perfect. The only problem with this recent product (the brown one instead of the black), is that my old surplus fittings are no longer compatible. You'll have to buy the new 1/2" to 5/8" universal fittings. There are also sections in the tubing that are thinner than usual, manufacturing defect, and is a bother to return after you install it, so I just repair them on the spot. that's why the quality is only a 3-star. But overall, this is an install and forget irrigation system, as you don't really need to maintain it for at least 16 years.

Rated 4 out of 5 by from Great Way To Water in the 21st Century I am converting the flower beds from spray heads to total drip hosing and adding a permanent drip line (pre-holed) around the foundation so that it waters with the sprinkler timer too. In the past, the spray heads sprayed a mist everywhere but never really wet the foundation unless you water frequently. This allows less frequent and I like the fact that one is pre-drilled and the other allows you to put the drip heads at the plant. I would have rated 5 star and 5 bar value, but there is a major disconnect in the section for fittings. There are two kinds of options offered, one by Rainbird and one by DIG. To connect to a 1/2" sprinkler location, you remove the current head and fitting and put a riser to connect to the hose. Rainbird sells a female 1/2" 90 on one side and with a barbed fitting for the hose inside diameter. It does not work on the DIG as the barb is too small for the DIG inside diameter. The Rainbird fitting that doesn't work on DIG ($1.93 each). It took a long time to figure out that the DIG solution is a female 1/2" 90 with basically a male garden hose threaded 3/4" end (Q59) which are $1.75 ea. Then you have to buy a female hose connector with a female slip fitting for the hose (#50001) for the 700OD on the tubing ($2.17 each). Worse is that the Q59 fittings are near impossible to find in The Home Depots. I had to go to 4 stores to find 12 of them for the 12 different locations. That makes the investment for me $50 more for the DIG instead of the Rainbird hose. The DIG tubing (5 rolls) offset this at $3 roll cheaper and I prefer the black color which blends with compost. All in all, the product is great with either solution but the fitting cost (Ts, 90s, and end caps) can add up quickly.

Rated 3 out of 5 by from Out of spec flow from emitters Quality looked good but there were many emitters that were dispensing far more than specified. All fittings worked like a champ, everything was as anticipated except the flow from the emitters. Although most emitters dripped, many actually flowed. Measured pressure showed the regulator was adequately controlling the pressure to 20-25 psi. A field of 128 emitters should have delivered 64 gal/hour but measurements showed they actually delivered some 380 gallons over a 2 hour period. The results were consistent for 10 separate tests.

Rated 4 out of 5 by from overall i am happy I have about 300 feet of this product in use currently. it works well and seems pretty durable. i have had it installed about a month and it has no leaks or breaking or anything like that. it comes in a roll so it is kinda tough to get it to lay strait so you will need to stake it down about every 10 feet or only real complaint is the emitters do not all flow at the same rate. and it is not all because of pressure drop you will find some flowing way more than others all throughout the length of the hose. overall i am happy if i turn on the water for a couple hours it waters my whole flower bed. i have the hose covered in mulch now but i observed the flows while checking for leaks prior to burial.
