How many drippers can I put on one run of tubing?
The number depends on the size of the tubing (1/4, 1/2 or 3/4) as each size of tubing has different GPH limitations. Another limiting factor in how many drippers you can use on a single run of tubing is the GPH rating of the drippers themselves. As an example 1/2 tubing can supply 220 GPH in a single run, which means that one could put 440 .5 GPH drippers on a run of 1/2 tubing or 220 1 GPH drippers or 110 2 GPH drippers.
Can I expand my system?
Yes, all of our kits and parts are designed to be compatible so that as your watering needs increase you can add to your system easily. Just keep in mind the GPH limitations of the tubing you are using, if you would exceed the GPH rating by expanding your system you may need to create a 2nd system or zone.
I want to use drippers, microsprinklers and spray jets on the same line. Is it possible?
Yes, our landscape kits come with all of these components and are designed to run off one line. You can use any watering devices in combination as long as you keep in mind the GPH rule for the tubing you are working with. Note: Mircrosprinklers and spray jets can eat up a lot of GPH.
Can I run my drip irrigation system 24/7?
The answer here is no because the faucet assembly parts (Pressure Regulator and Backflow Preventer) are not designed to be under constant pressure. If they are subjected to constant pressure they will eventually blowout resulting in the need to replace them.
How long should I run my drip irrigation system?
There is no set rule on how long to water using drip irrigation. It is really a guess and check method. There are two ways. 1) you can turn on your system for 30 minutes. After 30 minutes dig down into the dirt around you plants and take a look at the capillary action of the soil. If you are not happy with the results wait 45 min and repeat by increasing the run time of your system. Again check you soil. Continue this process by gradually increasing run time until you are satisfied with the run time.The second option is to choose a time that seems good to you and run the system for a few days. During this time monitor your plants if the they look very healthy then you are close to the required time. To maximize the efficiency of your system you may want to slightly decrease the water time each day until you notice a negative change. From that point you know exactly where the sweat spot is for watering your plants. If the opposite happens and you notice right away your plants look dry then increase the watering time until they look healthy again. Factors that effect watering time are: soil type, temperature, and humidity.
Is it possible to bury drip irrigation tubing?
Drip Irrigation tubing can be buried underground and/or covered by mulch. Keep in mind though that burrowing rodents like gophers can chew through the tubing. If you decide to bury your tubing keep an eye on your system to make sure everything is running properly so that if a rodent does chew through the tubing you can spot the problem immediately.
What is the order that I should connect the faucet assembly parts?
When connecting your drip irrigation system to a faucet we recommend the following order: Timer Backflow PreventerFilter Pressure regulator 1/2 Swivel adapter or tubing adapter
Should I use Pressure Compensating or Non Pressure Compensating Drippers?
Pressure Compensating Drippers have the following characteristics:Work at the stated GPH rating regardless of pressure fluctuationNon-Pressure Compensating Drippers have the following characteristics:Output can vary up to +/- 15% due to fluctuation in pressure
Can I add a timer to my drip irrigation system?
Yes, any drip irrigation system can be automated. In fact, studies have shown that timer automated drip systems are the most efficient as it eliminates forgetting to turn off the water an hour or a day ago. Beyond making the system more efficient timers also save you a lot of time. Once installed and programed you don't have to worry about watering you plants again.
What is Pressure Compensating?
Drip systems apply water to plants at very low flow rates. This minimizes evaporation losses and limits the water to the root zone of the plant by Putting water where it counts!". Pressure Compensating, or PC, is a term used to describe an emitter that maintains the same output at varying water inlet pressures. Therefore PC drip emitters compensate for uneven terrain, length of supply tube and varying inlet flows. PC drippers facilitate controlled watering, as each drip emitter performs to a pre-set flow rate (eg 1 gallon per hour), allowing water emitted over a length of time to be easily calculated. This ensures more efficient watering, reducing the risk of over-watering or under-watering. A non-compensating drip emitter will have varying output flow at varying inlet pressures. Therefore the flow will vary along uneven terrain, and each dripper will emit a different amount of water depending on its location on the supply line. The pressure to a drip emitter can vary due to the slope of the land and the length of the supply tube. If an irrigation system is installed down a slope, there will be higher water pressure at the bottom of the slope than at the top, and non-compensating drippers at the bottom will emit more water than those at the top. PC drip emitters will emit the same amount of water all the way down the slope, providing more even watering on uneven terrain.With all that in mind, don't worry to much about PC -vs- non-PC. Usually the difference in output between a PC and non-PC dripper will be in the 10% - 15% range. Unless your water is VERY expensive or you have a VERY large area to service, the PC -vs- non-PC issue is mute.
What is the difference between vinyl and poly irrigation tubing?
Vinyl irrigation tubing is made from flexible Polyvinyl chloride (PVC). Poly irrigation tubing is made from polyethylene. They perform the exact same function. The inside and outside diameter of the tubing can vary slightly, but it is usually not visible with the naked eye and has no bearing on usability. Poly irrigation tubing tends to have slightly longer life span than its vinyl counterpart. The primary difference between the two are that vinyl tubing tends to be more flexible than poly tubing. This can be either good or bad depending on your needs. Vinyl tubing can make tighter turns without kinking but it can sometimes be more difficult to insert barbed fittings into it; opinions vary.At Drip Depot, we choose to use poly irrigation tubing for all our kits and applications. First, we feel that poly irrigation tubing is easier to work with, especially if you let it lay in the hot sun for a while before working with it. Second, we feel that polyethylene is a more stable polymer and as such, is less likely to break down and enter the water stream. In the end, you should use whatever you feel comfortable with.
What are the limits and capcity of 1/4" tubing?
1/4" mircotubing should not exceed a run length of 30 feet and 30 Gallons Per Hour (GPH).
What are the limits and capcity of 1/2" tubing?
A good rule of thumb for 1/2" tubing is the 200/200 rule. 200 GPH200 FeetWhich means that you can run 1/2" tubing up to 200 feet maximum and draw up to 200 gallons per hour maximum. Those limits are very conservative but if you stay within those limits you are sure to have a working system.
