Suction lift and the number of sprinkler heads operating at any given time are the key determining factors in selecting a sprinkler pump. Determine the number of heads and multiply them by 3. The sum (gpm requirement) should be compared with the pump performance chart found on the pump carton.

How do I know what size sprinkler pump I need?

End users should determine the amount of water to be applied during the peak period by multiplying the size of the field by the amount of water in inches that must be applied. The result is then converted to gallons per minute (gpm), and this number determines the size of the pump.

How many gpm do I need for sprinklers?

The standard sprinkler flow rates, in general, are from 4 gallons per minute (gpm) from a 5/32-inch nozzle at 30 pounds pressures to over 11 gpm from a 7/32-inch nozzle at 70 pounds pressures.

How do I choose an irrigation pump?

There are two things you must absolutely know in order to select the right pump: the irrigation system operating pressure and the system flow rate. If anyone tries to tell you what pump you need without establishing what your needed flow (GPM or l/m) and pressure (PSI or bars) are they are just guessing.

What pressure do you pump a sprinkler system?

Water pressure is measured in pounds per square inch – also called psi. The average water pressure for most homes and businesses is between 30 psi and 50 psi; most sprinkler systems are designed to use pressures of around 30 psi.

How do I increase sprinkler pressure?

Remove a few sprinkler heads from each of the zones in your system and cap the plumbing that led to them. Decreasing the number of sprinkler heads will increase the water pressure in those that remain. Install a boost pump on the main irrigation line.

Does a sprinkler pump need a pressure tank?

No, the pressure tank is only for use if you want instant water like in a house and the pump replenishes the tank, your sprinklers will simply turn on when the pump is running.

How do I choose a pressure pump?

Typically, a pressure of 40 psi at the top of a building is ideal. Consult the installation and operation manuals for special fixtures for their required flow and pressures. Choose the number of pumps your system will utilize. For a small system below approximately 150 gpm, two pumps will suffice.

How many sprinkler heads should be on one zone?

At different pressures, the sprinkler head and nozzle will consume different amounts of water. For example, at 35 pounds per square inch (PSI) the 5000 Series Rotor using the 3.0 nozzle will use 3.11 gallons per minute (GPM). If your home’s water capacity was 10 GPM, you could place 3 heads per zone.

How high should sprinkler heads be?

The correct height for a sprinkler head is to have the top of sprinkler head just above the soil surface. No more than a quarter of an inch above the ground level. This lowers the tripping hazard, and a lawn mower can go past it without causing any damage.

Do I need a pressure regulator for sprinkler system?

Who needs a pressure regulator? Most if not all, pressurized irrigation systems will require a pressure regulator. An exception to this would be if you are using a gravity system with very low pressure, or very low flow.

How many sprinklers can I run on one line?

For example, you generally have a flow rate of 10 gpm from a ¾-inch spigot where you connect your hose. With your 10 gpm flow rate at your spigot, you could run two sprinklers at 5 gpm each. The best set-up is to run two hoses from the spigot–each to one sprinkler.

What causes sprinklers to lose pressure?

The most common cause of low water pressure in sprinklers is the backflow preventer valves not opening fully. There are two main pipes in your backflow preventer – one horizontal and one vertical. Each pipe has a handle that can be turned to run with the line or across to open the valve.

How much does it cost to replace a sprinkler pump?

Sprinkler Pump Replacement Cost The cost to replace a sprinkler water pump ranges from $200 to $500. Removing an old pump and fitting a new one should not take a professional long, but the material costs for pumps can be high, especially for a large and powerful model.

How much is a shallow well pump?

Typically, a well pump costs between $200–$500, not including the cost of installation. Here’s a breakdown of the cost for each type of pump and installation: Shallow well jet pumps—Since shallow well pumps sit directly within the well house, this pump replacement is generally the most affordable at around $200.

What is the difference between 0.5 HP and 1HP water pump?

For example if an 0.5 HP motor with discharge rate of 200 litres per hour takes 2 hours to lift the water, then an 1 HP pump with higher discharge rate 400 litres per hour can complete the task in less than 1 hour.

Can a pressure tank be too big?

The downsides to a larger tank are simply that it costs more and takes up more space. The only real problem is if you have too small of a tank you’ll cause the pump to cycle too quickly which wears it out faster.

Can you use a well without a pressure tank?

Take note that without a pressure tank, there will be a strain on the pressure switch or controller that can cause it to fail.

How do I calculate lawn sprinkler coverage?

If you wish to calculate sprinkler layout manually, first determine the area of your yard by measuring its length and its width in feet. Then, multiply these numbers together. You may want to draw your yard to scale on a piece of graph paper. Each square should equal 1 square foot of lawn.

How do you increase gpm on a sprinkler system?

If you pump your own water from a well, stream, or pond the only way to increase your water flow is to install a newer and/or larger pump, larger pipe leading to and from it, and possibly drill a deeper well. You will need to see the Irrigation Pumping Systems Tutorial for details on how to do that.

How deep should I bury my sprinkler line?

Dig for Your Sprinkler System The trenches will be relatively shallow, usually 6 to 12 inches deep, depending on your area’s freeze cycles and frost severity. The trench must also be deep enough to allow the sprinklers to retract underground to prevent breakage from lawn machines.

How deep do you bury a sprinkler head?

The depth should be around 6-8 inches to give you some room to work. Carefully lift the grass around the sprinkler head and flip it upside down on the lawn. With a small trowel, remove the dirt from around the sprinkler head taking care not to hit the sprinkler line.

How do I choose a pressure reducing valve?

By choosing a valve with a slightly higher Cv than you have calculated, you have the flexibility for higher flows in the future. Lastly, be sure the given flow rate is realistic and the pressures are accurate and proven. Always opt for exact calculations over educated estimates to ensure maximum efficiency.
