Here's how to tell.
Connect a tee to the outlet of the pump.
Install a pressure gauge in the tee.
Install a valve after the gauge.
Open the valve and start the pump.
Once water flows, close the valve slowly until you get 50 psi on the gauge.
Have a 5 gallon bucket nearby and measure how long it takes to fill the bucket at 50 psi.
If it fills the bucket in 30 seconds, you can attach heads to the pump that combined consume 10 gallons per minute.
Let me know how you do.

My traveling sprinkler sprays all the water miles away and does not saturate down any lower than 1/4 inch. Can I drill tiny holes in the sprinkler arms so the water will shoot up in the air or will th


NO!! Never drill holes in any sprinkler system as the size and shape of the holes are very carefully worked out to give you the best cover. Check that your system is running at the designed pressure. This is all important as if it is too much or too little the pattern delivered will be wrong and not efficient. Small holes and high pressures waste water by evapourating too much and cost too much energy to run. Low pressures can result in big droplets which carry well but may over shoot or undershoot the desired path. The most efficient distribution graph of any irrigator is designed to work within relatively narrow parameters.
You really should consult a qualified irrigation technician.

Tip

Haste to stop waste!


Too often we let our irrigation systems go on without really making sure that the amount of water, the pressure, the radius and other settings are what our lawn or landscape needs.
This causes not only a great waste of water and money but it may also ruin our flowers and plants.
Therefore here are a few tips to transform a wasteful sprinkler irrigation into the effective system it should be, and to keep a healthy landscape, lawn or garden.

1. When to water.
Watering your lawn and landscape should be differentiated according to seasons.
During warm months (May to October) irrigation should be activated between midnight and sunrise, so to minimize the water that evaporates.
While during winter, plants and lawns should be watered during the warmer part of the day to prevent water from freezing on the landscape.

2. Don't drown your plants.
Keep an eye on your lawn while the sprinklers are on and monitor when the water starts dripping off the sides. This way you will know how long your sprinklers should be left active for, so that the plants may absorb the water without being overwhelmed.

3. Avoid daily, light watering.

4. When watering plants with deep roots, water well and deep, until about half inch deeper than the deepest roots, in order to encourage downward growth.

5. When watering on a slope do it gradually. Run your sprinklers every 3 hours circa and aerate to increase infiltration.

6. Check your sprinkler's efficiency once a month.
Check for damaged, leaking, clogged or stuck sprinkler heads and for constantly soaked patches of grass or soil to detect leakage.
Make sure that the water is sprayed all over the area and that new additions or plants that grew higher and larger don't block the spray pattern.

7. In seasons in which the temperature reaches 30/32 degrees Celsius remember to run your sprinklers 5 to 10 minutes in the afternoon to cool the area. It reduces the symptoms of summer patch disease.

8. Create water zones by putting together the plants that have similar water needs, and water them accordingly

9. Be careful when mowing. If your sprinkle heads don't retract underground after irrigation, apply small flags on them so that while mowing you see them better and avoid damaging them.

I have a pedrollo pump that pressurise our sprinkler systems i took it for servicing and came back to install found out that the opening on the impella side is discharging water like opening a tap it...


There doesn't seem to be enough pressure. If it is connected with the sprinklers, you might have to separate the two. You can try to increase the pressure but be sure not to break the sprinkler system.

Not enough flow and pressure to run sprinkler system


pressure in centrifugal pumps depends on the number of impellers in the pump housing, the clearance of the impellers to the housing and the power of the motor to drive the impeller/s
volume flow is also important as a pump without a high output will not produce pressure
check the jet size at the foot valve that is used to help lift water to the pump
It is a jet pump and will have a smaller line back to the foot valve for that purpose
next wil jet pumps if there is too much flow to the outlet , the pressure required to help lift the water to the pump is reduced and the volume is also reduced
you indicate 4 sprinkler heads per zone but how many zones are operating at one time
check the expected delivered volume for the new pump against delivered volume of the old pump as a starter to find the reason for the poor performance of the new pump
check also the rpms of each pump as that also has a bearing on volume produced

Our auto irrigation system wouldn't turn off. We found the Davey XJ70 pressure pump was leaking so replaced the leaking pipe. Now the watering g system won't start. What do we do?


Hi Geralidine
Sounds like your pump is "air bound"...meaning that the impeller housing of the pump is full of air, and it cannot pump water.
Try bleeding the air out of the pump and put a positive pressure (garden hose pressure) and make sure that you shut the airbleed valve off after you start to pump.

I have an aquamate pump and when i connect it to a continuous sprinkler it stops and starts contiuously


The pump is putting out too much water for the sprinkler.
You can raise the pump shut off pressure at the switch until it is higher than the pressure that the pump runs at with the sprinkler operating. You should have a surge tank connected to the system to give the pump time to balance with the sprinkler.
You can use more water with the sprinkler. This could mean adding another sprinkler or increasing the nozzle size of the existing sprinkler.

Irrigation system problem


How big is your pump? How much HP rating? It could be a case of blocked water line. Just check your pipe lines and the gate valve for blockage. Just your e-mail

I have a 1/2 hp pump which I use to pump lake water to my irrigation system. The pump takes too long to turn on when the spicket is opened and sometimes too long to shut off when the water spicket is...


when using the spicket you use less flow than your irrigation system so a delay in the pump coming on is normal...otherwise if you are having the same problem when the irrigation is running..a pressure switch adjustment may be necessary...please follow the manufacturer instructions for your pressure switch.
