lol spout away...

i dont have volume measurements yet still sourcing the individual containers.. pretty sure im gonna use one of those large plastic storage boxes from like the reject shop oor go low.. i dotn have a volume yet so yeh... i will be hoping to not have to pump water higher than 160cm Max.. but yeh im a planner so i want to have a monitary value in the plans.. i love that my parents were avid gardeners cause we have an old irrigation drip system in the shed =D

also while we are on the topic of barricks, what are you guys thoughs on UV light filters or sterilisers in the sump filter, keeping in mind their is a finite funding.

cheers guys :)

It's not just the height you have to think about. The number of outlets also needs to be considered as well as the layout. A looped layout is more efficient. The flow rate on the drippers will also affect how big a pump you're going to need. Some pumps will have a graph on the box showing how much the flow rate will decrease depending on the height the water has to pump. Drippers also will have a flow rate. The number of drippers x dripper flow rate x the number of litres per hour you want to flow into each box gives you a litres per hour number which you need to match against the height adjusted flow rate for the pump.

You really can't choose a pump until you've got a better idea about the design.

ok.. when you say dripper flow rate are your reffering to it in hours because that doesnt make much sense to me why then you would times it by how much you want to flow into the tank per hour.. so what is the measurement of flow rate in and how is it found?.. and what is the general prefference on litres per hour you want to flow into each box ? also what is a looped system.. is this where the flow back is ran back in a tube to retain the pressure? or not lol

thank you

My mistake. You don't have to multiply by how much you want to flow into the boxes. The drippers will probably be fixed and while you might be able to reduce the flow you won't be able to increase it. The dripper flow rate is sometimes on the dripper label. Not always. If you go to a specialist irigation place they can probably look it up for you. If you go to Bunnings or a nursery then save yourself the frustration and just don't ask. You can test a dripper by pumping water through it and timing how long it takes to fill a container. Yes, looped system = equal pressure.

I offer these suggestions having NEVER calculated any of it myself with my drip system. I couldn't be bothered. I just bought the biggest pump I could find in Bunnings. Then bought an even bigger one when the first one was insufficient. The 2nd pump was still inadequate so I ended up using both. Then I changed the configuration to a looped system and don't need the 1st (smaller) pump anymore. So theoretically it's possible to figure it out. But I haven't personally done it that way. Much more fun just to wing it. *lol*

ok thanks heaps, im gonna start sourcing parts and drawing up a design.. im sure once that is all done we will have some further talks about pumps :) lol

thank you

o yeh and how much does it matter how much water you have flowing in per hour? i suppose the more flow the fresher the water, though is their a standard that is recommended?

Ask your Dad

As you said your parents are avid gardeners get Dad involved and he should be able to calculate for you its the same as working out how many sprinkler heads you can put in one section for the garden. Its always fun if Dad helps my Dad is in his 70s and he still helps me out be lost without him

Cheers
