Pump Recommendation

[Isan Farang]

Tomorrow the guys will plant my hedge and at present the ground is nice and soft due to the rainfall. After rain ends i need to devise a watering plan. There is around 400 plants to water so need a decent feed from the tank.

 

My plan is to get a submersible and place in the tank then cross over from pump hose size to 5/8 plastic pipe. Just checking what spec of Submersible pump i would require or any other options to keep things as simple as possible.

Don't use that small a pipe. You will take much longer than needed.

 

we have just got a new pump and plastic pipe for the same job. I insisted on the largest size that will fit it is a 1½" one SWMBO is now very happy with the speed of watering. Previously she was using one about the same size as you suggest.

Why a submersible? 

Look at a close-coupled motor/pump unit mounted next to the tank. 

Sketch out rough plan of pump / watering location and distances for better idea for recommendations.

Maybe the hedge is to hide the wall.

The two sides are 45m per side and the rear is 35m.

 

Would you have some idea on the pump i would require, also would there be any that has adjustable flow or can i just use a gate valve and open to adjust the flow.

 

These are the tank connections.

I used  2  inch to within 10 metres of the irrigation system them down to 1.5 inch then 3/4 to each sprinkler head "spray" ground level so water not wasted going everywhere, I water  about 500 trees for 3  minutes each tree daily. I  only water 20 trees per  time ( well the staff do) takes them about 1.25 hours to do the lot.  Area covered is  about  1.5 acres 6 rai?

Used the thicker better  "13" pipe (13 bar), will stand  up to bashes, digging  better. My pressure is about 4  bar in the pipes.

All is  buried except where each section goes to a concrete  post with a tap to turn on each section of 10 sprinklers, that pipe is also painted to stop UV degradation of the pvc

You need to spell out what you want, a permanent installed system, hand watered, 400 trees at once or a few at a time - so many variations on configurations, Alternately get the local pump supply shop to come and have a look.

FWIW this is the pump we bought, we specifically did not want one with a float switch as it is in our pool that holds a few hundred kilolitres.

 

I have cut the top restriction off as there was no need to limit the outflow.
