How to choose the best sprinkler water pumps
There are certain key considerations you need to carefully look at before deciding which lawn sprinkler pump to settle on. These considerations will greatly increase your chances of purchasing the best sprinkler water pump to suit your particular needs. According to our research, these are the vital things you need to consider when selecting the best sprinkler water pump.
1. Size of your sprinkler system
When buying a new sprinkler pump or replacing an old one, you need to carefully consider the size of your sprinkler system. You do not need a sprinkler water pump with 2HP to serve two sprinkler heads when a 1/2HP pump can comfortably do the job.
All the sprinkler heads have a specific GPM AND PSI rating which will help you determine the pump size that you require. The manufacture’s chart will help you in doing the calculations. For example, when dealing with a 40 psi sprinkler head it will roughly require 3.8 gallons per minute. This means that if your sprinkler pump has a motor rating of 12 gallons per minute, then you can comfortably use your pump in a 3 sprinkler head system.
The disadvantage of using a powerful sprinkler pump in a small sprinkler system is that you will need to install a pressure regulator. The regulator brings the pressure down to ensure you’re your water pumps and pump are not weakened over time due to too much pressure.
2. Pump location
Your general terrain will determine where to place your sprinkler pump. Remember that all pumps are not able to cover the same distances. When it comes to location you need to consider both the distance and height that you want to move the water.
- Figure out the pumping height: The rise in elevation or suction head commonly refers to the lift amount required to transfer water to the pump from the source. Although some pumps can handle around 25 feet, most are not able to lift more than 5 feet. The suction lift configuration is an important consideration especially when you need to lift water long distances. Go through the pump’s specifications to find out whether the pump can handle the required lift distance for your project.
- Distance to system : The water pressure will be affected by the distance you want the water to travel before reaching the sprinkler heads. You need to also consider the distances through the discharge pipe and the size. The discharge pipe usually increases as the distance increases, but you could always have a professional give you the proper guidelines.
3. Power supply
Sprinkler pumps require electricity to run and you must consider this fact. Most pumps have a standard dual-voltage system of 230 or 115-volt option. This is, however, not always the case and you need to look at the pump’s specifications carefully. Large pumps with 2.5 HP or more usually require a 3-phase source or 230-volts.
When living in rural areas, it is best to look for sprinkler pumps with several other power supply options like solar and gas generators. This is usually because remote areas experience electrical interruptions. You, therefore, need a sprinkler pump that can be pump using other different power sources other than electricity.
4. The pump should be self-priming
With self-priming pumps, you will never have to conduct the priming yourself. This is because the pumps work using compression and buoyancy laws to automatically get rid of air in the pumping system. However, you need to add fluid in the casing before starting. Never run your sprinkler pump dry because this will lead to damage and failure of your pump.
Self-priming sprinkler pumps are generally considered as being the best. Once you install a foot or check valve, you will never have to re-prime your pipe reducing your workload immensely. Priming is a simple task but it can be time-consuming especially when you do it often.
5. The casing material
Sprinkler pumps are often kept outdoors and therefore need a long-lasting casing. The best water sprinkler pumps have stainless steel, fiberglass-reinforced or cast-iron casings to ensure your pump doesn’t get damaged by the harsh elements. Your sprinkler is made up of several components that need to be protected.
Avoid sprinkler pumps with plastic casings because they will get worn out pretty quickly and damages often occur easily. Ensure your pump’s casing is heavy-duty before purchasing it. Notice that pumps with a plastic casing are cheaper yes, but they usually don’t have warranties. This shows you that the manufacturers themselves do not have faith that their product can last for a long period.
Best Sprinkler Water Pumps Buyer’s Guide
Do I need experts to install a new sprinkler system?
Sprinkler systems are rather challenging to install by yourself because of the many different components you need to consider. For a good functioning sprinkler system that properly covers your entire lawn, you will need the help of an expert. Replacing a sprinkler water pump is, however simple once you have the entire system in place. You can replace a sprinkler pump by yourself, but installing an entire sprinkler system needs professional help.
Why is my sprinkler pump delivering too much pressure?
This problem is usually caused by you using a large sprinkler pump for a small Irrigation system. Look at your pump’s specification especially the horsepower and gallons per minute your pump is supposed to deliver. If you are using a large pump in a sprinkler system with about 3 sprinkler heads, then you need to buy a pressure regulator. The regulator will bring the pressure down thus protecting your pipes and pump from damage.
How do I know if I have a 115 or 230-volt power source for my sprinkler pump?
The best way to determine whether you have a 115 or 230- volt power source is to have a certified electrician check it for you. Alternatively, you could trace back the wiring at the power source to your circuit breaker. The wires should either connect to a double or single breaker. Should they connect to the single breaker then the voltage is 115, and the double breaker voltage is usually 230. If you are wrong, then the pump’s motor will burn and you will have to replace it. Have an electrician determine the voltage for you so that you can be sure to avoid damaging your motor.
Is it cheaper to use 115-volts rather than 230-volts?
The amount of power your sprinkler pump consumes is the same whether you are using the 115-volt or 230 volts. Your electricity bill will be the same regardless of the voltage you decide to use. When it comes to electricity, you pay for the amounts of kilowatts used. The pump will draw double the amp when running on 115 volts when compared to the 230 volts. When multiplying the volt and amp to get the number of watts used, they will be the same.
What is the pump curve?
The pump curve referred to as the performance curve, in general, is considered as very essential. It is a graph showing the general performance capability of a particular pump. Sometimes it is displayed in the form of a chart but it generally shows the same information. The pump curve will show you how well your pump can sustain a particular flow rate at specific pressures. It is, therefore important to look at the pump’s performance curve to ensure it can comfortably perform a specific task. Reading and interpreting the pump curve is rather simple and you can do it yourself.
Do automatic sprinkler systems consume more water?
Automatic sprinkler systems use less water when compared to the manual system and they could save a lot in the long run. The automatic system is programmed to shut off immediately the required amount of water your landscape needs is achieved. Unlike the manual system which you might leave to run for a couple of extra minutes every time because you are not sure whether you have poured enough water. With the manual system, you could also simply forget to turn it off from time to time and this usually leads to heavy water losses. With the automatic sprinkler system, you could always customize further with soil moisture sensors and rain shut off tools to ensure you save more water and electricity.
