Irrigation DIY garden

Low water pressure for popup sprinklers

last year

Hi All,

I am looking for some advice before I install a sprinkler system.

I did the ‘bucket test’ as I do not have any method of reading pressure. This involved timing how long to fill a 9m bucket from the outside tap. 21 seconds. I saw the formula 60 / 21 x 9 = Flow Rate of 25.7.

I then understand the total flow rate of all the sprinkler cannot exceed the supply flow rate of 25.7.

My garden Is 13 Meters x 12 Meters and about 6 Meters away from the supply tap. I was planning on burying 19mm poly pipe and installing some pop up sprinklers. Ideally on one supply so they all come on together. When looking at sprinklers my supply flow rate seems to be a problem.

Any advice on solution with low water pressure would be greatly appreciated.

1. Size of pipe

2. Type of sprinklers

Thanks

Use drip irrigation instead.

micro spray emitters will also work based on your plantings.

Water Pressure Regulator Installed. Slow Sprinklers
Q

Gio, I would say you need to install the pressure regulator as close to the house as possible (it usually goes in the garage with a shut off valve next to it) and leave the sprinkler connection (if it is from the main house line) between the regulator and the street. Check your outside faucet (house) pressure with a pressure tester that connects to the faucet from the hardware store. The pressure should be at 45 to 55 psi. If not, then turn the nob on the regulator adjustment screw to achieve that range. Aloha

You can flush the head by removing the nozzle and turning the zone on for a few seconds. If water comes shooting out, then the blockage is either gone or was never the problem. Also, check the filter under the nozzle for debris.

low pressure watering

Sorry, but the last post is a bit misleading . Atmospheric air pressure at sea level is 14.7 psi. The water pressure at the base of a 6 foot water elevation is .433 x 6 =2.60psi guage pressure. If your interested in the absolute pressure, then it would be atmospheric(14.7 at sea level) plus guage( 2.6psi) for a total from this example of 17.3psia. Guage pressure is generally what you would go by to figure your losses in a sprinkler system. If you use absolute values for any of your readings, then all your calc's have to be in absolute values. The end result will be the same either way as long as you stay with the same type values. I would just stick to guage pressures.

I'd disassemble the master station to see what wasn't working, and why. It may need a rebuild kit if one is available.

==>> that is a huge garden ... and you want ALL the sprinklers to water it all at one time.. a few pix of your garden will help us help you ......

your flow rate is the least of your problems ... physics might be the bigger problem ... btw.. as to the supply line ...the smaller the pipe.. the slower the water moves thru it ...

plz explain what you are growing.. and how you are growing it in this monster garden bed.. if you have lined out veg crop.. then drip is definitely the way to go ..

and you should look into zones ... no need for electric switches.. water one or two zones a day ... cycling over a few days all the zones ...
