Q: Hi Jim I'm wanting to irrigate my farm garden approx 75 ft x 75ft with a gas powered pump I have a creek for a water source about 150 to 200 ft from my garden which type of pump would best serve my needs thanks Jim
by Phil B from Missouri on April 02, 2014

A: Thank you for your interest in Water Pumps Direct. Most any water pump would handle your application. It depends on how you plan to "water" your garden. If you are simply watering with a garden hose and NO nozzle, any 1" GAS DEWATERING PUMP would do a fine job for you. Please note that the pump should be as close to the water source as possible and you should use a good quality suction hose to insure that it does not collapse during the pumping process and a good quality strainer to prevent any debris from getting into the pump. Most any garden hose will suffice however, on the discharge side of the pump. If you prefer to use a nozzle or sprinklers, you might be better served by an electric SHALLOW WELL PUMP or a SPRINKLER PUMP or HIGH PRESSURE GAS PUMP. These pumps would provide a higher pressure or PSI that would be needed to provide better coverage and proper operation of the nozzle or sprinkler heads.
If you have additional questions, please let me know.

Water Pumps Direct Recommended

If you're looking for a portable water pump for home or work this pump is for you. Weighing only 13 pounds and moving up to 2300 GPH, this water pump is ideal for emptying pools, flooded basements, and water-logged job sites. Portable, powerful, and affordable...what else could you want in a water pump?

Pumps Up Hill
I purchased this pump to fill a tank with water for my deer food plot. I used a 50" 5/8" intake hose to pump water up a 6' bank from a creek and two 50' garden hoses to carry the water up a slope to my holding tank. The pump worked great and did eveything I wanted it to do. I recommend using silicone on all hose connections to prevent air leaks and get a good suction. Hard to start the first time ,easier to start after warming up.This is a great little pump and I do recommend it.
Pros: Light Weight, Price
Cons: Hard To Start

Could Not Get It To Work For What I Wanted To Use It For
Tried to pull water from an abandoned well. Had approximately 16 feet of 1" PVC pipe, but it would not pump. Even though there was water in the well.
Cons: Could Never Get It To Work Will Look For A Better One Elsewhere

Gary,
That pump should work for the application you're using it for. I would suggest contacting Earthquake directly @ (800) 345-6007. They should be able to troubleshoot the issue you're having or direct you to a service center to see if warranty work needs to be performed on the pump.

Excellent Pump
I have a hunting camp in the Florida Everglades, no electric or city water. We pump our ground water to holding tanks utilizing a gas powered water pump. Pump worked well for years but no longer works.The pump we had was heavy and hard to start at times. I wanted a pump that was smaller more efficient. Did a internet search came across Water Pumps Direct. Found the Earthquake pump.

I was skeptical at first about the price, power and quality of this small pump. Their were several reviews... more

Does What I Wanted
I bought this pump to fill a 210 gallon tank from the creek to water my garden. It works very well, but sometimes is a little hard to prime. I run it at about 1/2 throttle, and fill the tank in less than 20 minuets. It's very light, and easy to place. Great little pump.
Pros: Easy To Store, Light Weight, Price, Fast

A Great Little Pump With A Tempermental Engine
As the saying goes, the quality of life is inversely proportional to the number of gas engines one owns. However, this little pump is a winner. I use it to pump salt water from the Gulf to my beach house bait tank -- about 400 feet with a head of 20+ feet. I uses a foot valve on the end of the intake line (PVC Pipe) to hold the prime because the pump will not self-prime. The only issue I have is that I have to use about 1/2 to 2/3 choke to keep the engine running with the 20ft head as the... more
Pros: Easy To Use, Price, Light Weight, Easy To Store
Cons: The Motor Is A Bit Tempermental

This "earthquake" Rocks!
I bought this little pump to run a 1.5" gold dredge. I haven't been able to test it on the dredge so far but I gassed this little guy up right out of the box and it fired off right away.

This thing is thirsty for water and pumps it very well. My only complaint (if you want to call it that) is that the engine has to remain choked about half way at full throttle even after it is warmed up. So maybe burning just a bit lean from the factory or it could be this cold northern air. I am very... more

Earthquake 4310
Bought this pump to run 1 1/2 inch gold dredge. It runs the high banker part just fine but didn't perform as well as others on the suction dredge part. It weighs 15 lbs bone dry, just a little heavy. The motor is of good quality and starts and runs quite well. Has a manual gas tank vent on the cap which is handy for packing since you can shut it off and wont leak. Remember to open it before running the motor or it won't run too long. Some say it doesn't have a check valve. The check valve... more

Portability Of The Earthquake Wp4310 Water Pump
I am from the Philippines working as a technician on board ocean going Cruise liners. I bought this product online andit was delivered and stored at my company's head office in Florida, after my contract finished. I picked up this pump at our office in Florida checked the content and re packed it again in its original box.Put it in my Delsey hardcase shell luggage and it fit inside as it is. Went to the airport checked in the baggage with the pump inside and fly back to Manila
