How to increase pressure on automatic sprinkler system?

[bilal4190]

hey guys. 
just started the DIY irrigation system. The water pressure is very poor. Attached is the picture of the yard to get the idea of the size it’s just the back yard I got same size of front yard I haven’t touched. The setup is for 15 sprinklers. 

My setup: 

25mm poly pipes 

1000L water tank 

k1 k rain water sprinklers 

water pump (picture attached) 

what else do I need to build pressure. It only sprays water till 3 feet. I have tried adjusting the water pressure gauge but still no results. 

thank you

Hello @bilal4190 

Would it be possible for you to post a photo of your pump set-up? This will give our members a chance to assess your pump. We can then make recommendations on how to proceed.

The pump that you have is the Ozito 800W Constant Pressure Pump. It is rated at 3,600L/H so if you have a 1000 litre tank it will drain it in just 17 minutes. Unless it was typo error, and you have a 10,000-litre tank. If that is the case, it's possible that air might be trapped in the priming tank of the pump.

I propose turning your pump off and filling the priming tank and restarting the pump. If you still have low water pressure there might be a blockage in the inlet pipe. I recommend double checking your connections and see if there might have been an accidental leak somewhere in your irrigation system.

If you need further assistance, please let us know.

Thank you very much . 
yes it was a typo. And I have refilled the pump 
Some progress has happened since i posted. The tap and the timer was not rated for the pressure coming out of the pump and it restricted the flow I  have attached the straight pipe to the sprinklers they were perfect. 
now the next Step is what kinda tap is recommended that does not restrict the flow also what’s kind of solenoid valve should I put . ? 

thank you

Hello @bilal4190 

If you've connected your pump directly to the tank all you need is a controller that can handle the amount of water coming out of the pump. Your Ozito pump has an electronic flow switch that senses pressure change in the system. If water is stopped at the outlet, the pump will notice this pressure change and stop.

When the outlet opens again the computer will notice this change and turn itself on. The only timer I saw that might work for you is the Rain Bird Single Outlet Digital Tap Timer. However, I'm not sure if it will be able to handle 15 sprinklers. 

In regards to an outlet tap, I suggest using an ordinary Kinetic 15mm Brass Garden Tap. This should be more than adequate and will be able to handle the pressure coming out of the pump.

If you need further assistance, please let us know.
