Tips & Tricks

Upgrade Your Drip Hole Punch & Save Time

A clean cut makes it easier

Some drip irrigation hole punches are shaped like a pencil and simply poke a hole as they push through the drip irrigation tubing. They require more force and can slip off of the drip tubing before they make the hole. The Super Punch (shown here) has a squeeze handle and is only $9.90. A less expensive option is our Deluxe Hole Punch which has a sharp, circular cutting edge. It's comfortable, easy on your hands, and costs only $3.60.

A Paper Clip Quickly Cleans a Hole Punch

Insert the wire to clear the tool

A good hole punch will actually cut a tiny circle out of the drip irrigation tubing. The plug of drip irrigation tubing can be removed from the cutting edge of the punch with a paper clip. Push it through the cutting end to clear any plastic debris.

Control Water Flow to Flower Pots With This Little Valve

1/4" Flow Control Valve inserts into micro tubing

If you use a drip irrigation system to water hanging baskets or flower pots, put a 1/4" flow control valve  on each pot. You can reduce the drip irrigation flow or shut it off completely. It's handy if the pot is has not yet been planted and you don't want to water it.

Fix Little Holes With a Goof Plug

Doubles as a 1/4" end plug

If you make a mistake and poke a hole in the wrong place on a drip line, insert a goof plug (small barb). If the hole gets worn and leaks a little, pull the plug out and use the large barbed end. Goof plugs are also used to plug the end of 1/4" micro tubing.

Adjust Water Flow to Garden Boxes With a Flow Control Valve

1/2" Valve fits over mainline tubing

These drip irrigation valves are great when you have garden boxes or drip areas that you may want to turn off seasonally. You can reduce the flow or shut it off completely. 1/2" Flow  Control Valves are installed just like a compression coupler.

Fix Big Holes With a Coupler

If a goof plug won't do the trick

If you have a hole in a mainline poly pipe that is bigger than a goof plug, a compression coupling is the fitting to use. Make a clean cut and insert the two tubes into each end of the coupler. No glue required.

Threaded End Caps Make Winterizing Easy

Unscrew cap to flush or drain drip tubing

Install them now and thank yourself later. A threaded cap at the end of the drip line allows you to flush the drip line to clean it and drain the line of water before freezing winter temperatures set in. Learn more about winterizing your drip irrigation system.

FAQ

Is all 1/2" poly tubing (drip mainline) the same?

The short answer is no. Poly tubing may be called “1/2 inch” by manufacturers and retailers but if you look closely you’ll find that the tubing has specific Outer Diameter (OD) and Inner Diameter (ID) dimensions.

Common OD dimensions are:

.700 inches (called “700") Black fittings
.620 inches (called “620”)  Green-ringed fittings
.710 inches (called “710”) Blue-ringed fittings
.580 inches (called “580”) Yellow-ringed fittings
.455 inches called "455") Red-ringed fittings

We carry 700 poly tubing and Compression fittings. We also carry fittings and adaptors for many of the common tubing sizes.

How far can I run the 1/2” drip poly tubing (mainline)?

The maximum drip mainline run is determined by the flow rate, water pressure, the number of emitters on the line, and distance between the emitters. Our 700 tubing has a maximum flow rate of 240 gallons per hour. We recommend a 20psi or 30psi drip regulator.

For most residential drip irrigation systems using a hose bibb (faucet, spigot, hydrant) as the water supply, follow these guidelines:

Maximum drip mainline run: 500 ft
Maximum emitter output: 240 gallons per hour
 
Since a typical hose bibb delivers 240 gallons per hour, you can put 240 1 gallon-per-hour emitters on the line (or 480 1/2 gallon-per-hour emitters or 120 2 gallon-per-hour emitters).

This works up to a point. If you run your drip poly tubing over 500 feet, there will be some pressure loss, limiting the number of emitters that you can install. For a maximum length run chart and more details read our tutorial on Installing Drip Tubing and Fittings.

How do I add on to my existing drip system?

We have a great selection of drip tubing coupling adapters for varying sizes of drip tubing. They are color coded. The first step is to determine the Outer Diameter (OD) of your tubing.  

Common OD dimensions are:

.700 inches (called “700") Black fittings - 700 Compression Coupler
.620 inches (called “620”) Green-ringed fittings - 700 x 620 Compression Adapter
.710 inches (called “710”) Blue-ringed fittings - 700 x 710 Compression Adapter
.580 inches (called “580”) Yellow-ringed fittings - 700 x 580 Compression Adapter
.455 inches called "455") Red-ringed fittings - 700 x 455 Compression Adapter

If you find that your existing tubing is not 700, simply add the appropriate coupling adapter to your order to go from your tubing to 700.

Can I bury my drip tubing?

We do not recommend burying drip tubing in the soil. However, a layer of mulch on top will extend the lifespan of the drip tubing. Buy Drip tubing here.

Coupler

Also called a coupling, it joins fitings and pipe of like size together. Couplers may be slip, threaded, barbed or compression or combination thereof.

Connecting unlike items is called “adapting”. See Adapter.

Compression Fitting

Fittings used to connect lengths of 1/2" and 3/4" drip tubing. The tubing is simply inserted into the compression fitting. Glue is not required. See also Poly Pipe.

 

Goof Plug

Also called mistake plugs, goof plugs are used in drip irrigation to plug up small holes in mainline drip tubing. They are also used as end caps in 1/4" drip micro tubing. It is always good to keep a handful of goof plugs on hand.

ID

Abbreviation for Inside Diameter of pipe.

OD

Abbreviation for Outside Diameter of pipe.
