Tips & Tricks

Save water in cooler weather

Make Seasonal Adjustments

Create your watering schedule based on mild weather conditions for your area. In most cases this will be in early spring. From there you can use the “Seasonal Adjustment” feature on your controller. For example, in the summer you can increase your overall watering duration, and in the fall you can decrease it.

Use Teflon tape on pipe threads

For a water-tight seal

Always use Teflon tape with pipe-threaded fittings. Wrap Teflon tape clockwise 4 - 5 times around pipe threads. Hose-thread fittings use a hose washer to make a water-tight seal.

Sloping Property? Use Pressure-Compensating Emitters

Drip emitters with consistent output

When installing a drip system on a slope, non-pressure-compensating emitters will deliver less water at the top of the slope and more at the bottom. Install pressure-compensating emitters to ensure even flow rate even if the elevation changes. Non-PC emitters are best on flat lanscapes.

Install a rain or soil moisture sensor

Many irrigation controllers work with weather sensors

Rain and soil moisture sensors work like an on/off switch. They are easy to install and work with most irrigation controllers. Once installed, they will turn the system off until the rain stops and things dry out.

Watch for runoff

Check sidewalks and driveways

Be green and save money too. Check often for excessive runoff from your irrigation system as well as puddles or pools of water. It may only take a slight adjustment of nozzles, spray emitters, or water timers for substantial water savings.

Check lawn brown spots closely

Disoloration is not always a sign of under watering

Often, overwatering will cause grass to look sickly. Check the soil moisture before making adjustments to your watering schedule. If your lawn has brown spots, it may need fertilizing, aeration, or disease control.

FAQ

I want to install my own drip irrigation system. Where do I start?

The best place to start is our Drip Irrigation Basics & Installation Tutorial. You'll learn how to plan & design a drip system, connect to a hose bibb, and how to compare drip emitters.

How do I determine my household water pressure?

Please read our tutorial on Determining Your Household Water Pressure.

How do I determine my water flow rate?

The flow rate is the amount of water flowing through your water supply line. Since drip emitters and micro sprays consume x gallons per hour, it is important to know the flow rate available to feed your emitters. It is measured in gallons per hour (GPH). To determine the flow rate out of your faucet (hose bibb, spigot, hydrant), read our tutorial on Determing Your Flow Rate.

How do I hook a drip system up to the water supply?

Our Connecting to the Water Source tutorial will outline all the components needed to set up a hose bibb connection or connect to the main water supply.

How do I choose a pressure regulator?

Drip irrigation systems are designed to operate between 20 and 30 psi. Most household water systems are set between 50-70 psi (or higher). A pressure regulator is required to reduce the household water pressure down to the proper range for drip systems. When choosing between a 20 psi and 30 psi regulator, here are some guidelines:

• Non pressure-compensating emitters:  Use 20 psi regulator.
• Fogger mister bubblers: Use a 45 psi regulator.
• Hanging Baskets: Use a 30 psi regulator
• Drip Tape: Use a 10 psi regulator

When using micro sprays and bubblers be sure to consult the water output charts for each product as flow rates very with pressure. For more details, read our tutorial: How to Choose a Drip Regulator. 

Is a filter required?

While a filter is not required, it is highly recommended. Even the cleanest water has small particles in it that can clog drip emitters. Micro sprays are especially susceptible to clogging as the orifices in micro spray components are especially small. Debris can enter a municipal water supply if a mainline breaks or when there is new construction in the area. Well or lake water should always be filtered. Without a filter, you may need to manually take apart emitters to clean them and remove debris that would have been caught by an inexpensive filter. Compare and buy filters.

Back Flow

An unintended reverse flow of water from an irrigation system into the main water supply. It is caused by backpressure or a back siphon. Irrigation systems come in contact with many potentially harmful materials including fertilizers, pesticides, bacteria, insects, and animal waste. These contaminates will pollute household water supplies if sucked back in via backflow. 

 

Backpressure can be created by a pump in the system or when pipe/sprinklers in the zone are at a higher elevation than the point of connection to the water source. 

 

Back siphoning can occur if there is a break in the supply pipe and/or a drop in pressure of the supply line. Backflow most commonly occurs when there is a temporary sudden loss of pressure from the main water supply. 

 

A properly installed backflow preventer will prevent backpressure or back siphonage from impacting the main water supply. 

Backflow Preventer

A device installed on an irrigation system to prevent water in the irrigation pipes from flowing back into the main (household) water supply. Irrigation systems come in contact with many potentially harmful materials including fertilizers, pesticides, bacteria, insects, and animal waste. These contaminates will pollute household water supplies if sucked back in via backflow.

Types of Backflow Preventers

Air Gap

An Air Gap is a backflow prevention system that prevents water from being sucked, or siphoned, back into the water supply. There is a physical space (vertically) between a discharge pipe and the flood-level rim of receiving vessel. The receiving vessel is open and not under pressure.

The air gap must be at least double the diameter of the supply pipe measured vertically above the overflow rim of the receiving vessel. The Air Gap must be 1 inch or greater.

While not always practical, an Air Gap provides the maximum protection available against backflow (and potential contamination of water supply).

Atomospheric Vacuum Breaker (AVB)

An Atmospheric Vacuum Breaker is a backflow preventer that is installed above the highest point in an irrigation system. It contains a float (air inlet valve) which closes when water is moving in the normal direction, keeping air out of the system. If a siphon begins to form, the float drops to allow air into the system, breaking any potential backflow into the main water supply. Atmospheric Vacuum Breakers should be installed at a minimum of 6" above the highest pipe or outlet in the system.

Double Check Valve Assembly (DC)

A Double Check Valve (or double check assembly) is a backflow preventer containing two positive-seating check valves assembled in series.  A ball valve or gate valve is installed at each end for isolation and testing of each check valve. Small ball valves, called testcocks, provide locations for attatchment of testing equipment.

The benefit of the double check valve is that it does not need to be installed abouvr the highets head or pipe in the irrigation system. It can be installed underground in a valve box.

Pressure Vacuum Breaker (PVB)

A Pressure Vacuum Breaker (PVB) is a backflow device containing a spring loaded check valve and an independently operating air inlet valve. Since the PVB is not designed to protect aginast backpressure, it must be installed at least 12" above the highest head or pipe in the irrigation system. It provides a better solution against backsiphonage than an atmospheric vacuum breaker as the spring-loaded valve dows not rely on gravity as does the AVB. 

Reduced Pressure Principle Assembly (RP, RPA, RPZ)

A Reduced Pressure Principle Assembly is a backflow device consisting of of two two independently acting check valves and a mechanically independent, hydraulically dependent automatic pressure differential relief valve located between the two check valves. The relief valve maintains a reduced pressure zone between the two check valves that is lower than the supply pressure. A ball valve or gate valve is installed at each end for isolation and testing of each check valve. Four small ball valves, called testcocks, provide locations for attatchment of testing equipment. The RP must be installed 12" above the highest head or pipe in the irrigation system.

Filter

A filter contains a screen that is designed to remove particles from irrigation systems. Filters are critical components in a drip irrigation system. Drip emitters may clog if proper filtration is not provided. Typical screen mesh is 120, 150, and 200 mesh. The greater the number, the smaller the openings in the screen. 200 mesh is recommended for foggers (misters).

Pressure Regulator

A device that lowers water pressure on the downstream side and maintains a constant operating pressure. Regulators are commonly used in drip irrigation applications as drip tubing and fittings are usually rated to operate at pressures lower than most household water systems. Always install a regulator after a valve and filter. They are not designed to be operated under constant pressure.

Valve

A manual or electric irrigation device used to control the flow of water. These valves fall into two main categories:

 

1. Shut-Off Valves. Generally  installed on the main water supply to control the flow of water to the irriagtion control valse and or to prevent the flow of water back into the main water supply.

• Gate Valve: A manual on/off valve that uses a "gate" mechanism to drop a metal plate into place when the wheel handle is turned. This should only be used for emergency shut off and not regular on/off usage.

• Ball Valve: A rotating ball opens and closes the valve. Water passes through a hole in the center of the ball. It and is a better choice for regular usage. In fact, hose end timers (for drip irrigation) use ball valves as the internal mechanism.

• Check Valve: Many Backflow Preventers are check valves.

• Quick Coupler Valve: Often made of brass, it is an underground valve that is under constant pressure and designed to provide a quick water connection.

 2. Irrigation Control Valve. Also called remote control valves, they operate at 24VAC and are wired to an irrigation controller.  With the exception of anti-siphon valves, they are usually placed underground in valve boxes. Backflow Preventers are installed prior to the irriagtion control vales to prevent back siphonage. 

 

• Globe Valve: Inlet water comes into the  from underneath and leaves the valve at a 90 degree angle

• Angle Valve: Inlet water comes in from one side of the valve and leave the valves on the opposite side (in a straight line)

• Anti-Siphon Valve: An electric valve with a built-in atmospheric vacuum breaker. They must be placed 12: above the highest point in the irrigation system in order for the valve to successfully prevent backflow of water into the household water supply.

• Hydraulic Valve: Uses water pressure (modified via small flexible tubes) to operate the valve.

• Master Valve: Electric valve used in irrigation systems to control main line water flow to a manifold (group of irrigation valves).

Clock

Valve Box

A rigid plastic container which covers and protects underground irrigation valves. It has an access lid for valve maintenance. See also Valve, Controller, Direct Bury Wire, Two Wire. 

Zone

Also called a watering zone, a "zone" is an individual watering area controlled by a single irrigation valve. It may be a group of sprinklers or a drip irrigation system. When designing an irrigation system, plan individual zones so that each contains plants with similar watering requirements. Watering zones should also consider micro climate factors like amount of sun exposure vs. shade, and design elements like sidewalks and driveways. With proper planning, you can create zones that allow flexible programming on your irrigation controller. See also Valve, Controller.

Watering Zone

See Zone.

Hose Thread

Officially called "Garden Hose Thread" (GHT), hose threads are found on garden hoses and many irrigation parts and adapter fittings. Generally referred to as "3/4" hose threads" the outer diameter is 1.0625 inches and has a pitch of 11.5 tpi (threads per inch). Hose threads are NOT the same as pipe threads and should never be screwed into pipe threaded fittings.   

Male hose threads are found on the outside of a fitting and thread into female hose threads.

Female hose threads are found on the inside of a fitting and accept male hose threads.

Hose threads do not require Teflon tape or pipe dope (like pipe threads), just a hose washer. If you find a water leak with hose threads, it is most likely a worn hose washer. It may be time to replace it. Hose washers are found inside fittings with female hose threads. See also Pipe Thread, Adapter, Swivel, Hose Washer, Teflon Tape

Operating Pressure

Pressure Vacuum Breaker

See Backflow Preventer

Pressure Compensating

Pressure Compensating Emitters. The output will not vary with changes in elevation and pressure. They deliver the stated gph (gallons per hour) even if pressures range from 10-50 psi. These emitters are best used with elevation changes. They are self-flushing to reduce clogging. See also Emitter, Non-Pressure-Compensating.

Pipe Thread

The common term for National Pipe Thread (NPT). Pipe threads require Teflon tape or pipe dope to create a water-tight seal. Do not thread together pipe threads and hose threads. See also Teflon Tape, Pipe Dope, Hose Thread.

Teflon Tape

A non-adhesive tape (made of Teflon non-stick material) that is used to create a water-tight seal with pipe threaded fittings. It is tightly wrapped in a clockwise motion 3-4 times around the male pipe threads. Male and female fittings are then threaded together.

Hose Washer

Rubber gasket found inside fittings with female hose threads that makes a water-tight seal. See also Hose Thread.

Automatic Valve

A valve which can be remotely operated either electrically (the most common) or hydraulically. Automatic valves are commonly used as "control valves" for irrigation systems. See also Valve, Bleed Valve.

Controller

Also referred to as a clock, or timer, an irrigation controller is an electronic, programmable device that controls the timing of automatic electronic valves in an irrigation sytem. The valves control the flow of water to sprinklers and drip systems. The contoller sends electricty (low voltage) to the valve on the day and time set in the controller schedule and for the duration programmed by the user.

High end controllers employ weather-based controls ( ex. rain sensors, soil moisture monitors, real-time weather data), internet connections, cell phones, and remote controls for use with sophisticated irrigation systems. See also Irrigation Schedule.

Schedule 40

A PVC pipe classification (often written as SCH 40 or SCHED 40), commonly used for main line water pipes. Schedule 40 pipe is thicker than Class 200 and can withstand higher water pressure. The "schedule" number is not a specific measurement but rather a designation representing the reletive wall thickness of the pipe and water pressure rating (psi) for that pipe.  For additional classifications of irrigation pipe  see Shedule 80 and Class 200.

Diaphragm

The diaphragm is a flexible rubber membrane inside an automatic irrigation valve, between the upper chamber of the valve and the smaller valve inlet (water supply). When the valve is closed, both the upper chamber of the valve and the valve inlet are filled with water. Since the upper chamber is larger, a greater suface area of the diaphragm is covered with water than on the inlet side. This water pressure differential keeps the valve closed.

When the solenoid is electronically activated, it releases water from the upper chamber above the diaphragm. This reduces the water pressure above the diaphragm and allows it to rise and open the valve. Water will now flow through the valve.

A spring inside the valve pushes against the back of the diaphragm, but it does not exert much force on the diaphram. It would stay closed without the spring. See also Valve.

Bleed Valve

Used to manually turn on an automatic valve. a bleed valve is located on or near the top of the valve. It can be a small screw, a lever, or built into the solenoid. When turned, the bleed valve allows water to flow out of the cavity over the internal diaphragm of the valve. This causes a pressure differential and opens the valve. 

If the bleed valve is an external type, a small stream of water will flow from the bleed valve and outside of the valve while it is on. An internal bleed will keep the water inside the valve and empty it into the downstream side of the valve. See also Valve.
