Gravity fed irrigation system

[Matt_B]

I've got a few meters of 20mm water pipe and was thinking the best way to rig it up to my butt and being able to open a ball valve to water my greenhouse

The pipework will be in a U shape with the feed in the centre, i've also seen gardena spray heads that I think will screw into the pipe, I think i'll need 6 spray heads to cover the bed, but have been wondering if there will be enough pressure from the butt?

Just wondering if anyones done anything simular?

Hi Matt.

I use a pump with my water butt, there would probably not be enough pressure unless your water butt outlet is at least 4' above the area you want to irrigate. even then if it is over any great distance the water is more likely to trickle out rather than spray. other members may differ, so just my opinion

I have two water butts connected by a siphon and then another siphon/gravity feed tube into the greenhouse. The water feeds to grow bags via plastic dripper valves. I find that this arrangement will automatically water my toms for up to 5 days.
There is further information on my website under "greenhouse watering"

GREAT website

Liking the way your using 2 water butts, seems like your using the first as a settlement pit and syphoning off the top for clean water into the second.

Definatly going to try now

Thank You

Hi cherrybomb

My greenhouse is about 100ft from the house so was thinking of ways without electrickery or mains water, The hose does reach but seems a bit harsh when pointing at the soil, I nearly bought a adjustable lance for it today but for the price I was thinking of a diy watering system

Thanks for the reply

hi stewart here, i collect water for my tunnel by i piece of gutter on the ground ond the cover runs in to the gutter allong the ground in to a barrel in the ground then ive got a 12v boat pump with a float switch in barrel that pumps it to a 1000ltr tank at high level giving me good presure for hose.it works great ,battery lasts about 3 weeks then give it a charge.stew.
