10 1/4 inch drip lines..no drippers, how much pump required?

[uraceulose]

I'm going to do a RWDC with top feed. 10 sites in a tote

How much pump should I need to move the water up (vertically) roughly 2 feet then into a T with a manifold.

Then want to run ten 1/4" drip lines with no drippers and just let them drip over the tops of the pots.

My current pump is about 250 gallons per hour. The first 8 sites drip great and are constantly running. The last 2 don't get anywhere near the flow of the others.

Was going to just go one size larger on the pump but would like to be sure.

Thanks so much for any advice and this forum is great,

Donnie

i would go a couple sizes over. better overkill than not enough. also try setting up your dripper manifold in a closed loop system rather that a straight line with a stopper at one end if you arent doing that already.

DH,

Thank you.

What do you mean closed loop?

I was just going to put the pump in the bottom of the plants root zone reservoir then come straight up out of the top with a T. Then off from the T into 2 manifolds. Then 10 drip lines with no drippers running constantly.

Ura, DH is suggesting a closed loop manifold because it will have more even pressure throughout. A linear manifold will have less pressure at the end which can result in uneven watering.

Thanks

So, I should just make a square shape so the water can return to the pump outlet? Isn't it the same as just coming straight up with a piece of PVC, capping the end and drilling holes down it vertically for drippers?

I just don't see how making the square shape is any different from a straight piece?

Thank you and I'm reading the link more thoroughly right now..

Oh okay, thanks again guys. Will get it setup

Putting the drippers on the ends of your tubing will help even out the flow. I have seen this make a lot of difference. In reality drilling the holes horizontally would be better either by adding a tee or an elbow and a piece of PVC. If done vertically the top holes don't get the same pressure as the lower holes.

Listen to the doctor, on the manifold, if you have extra drip line you could run it along the edge of your table and cut/place a "t" to every plant site
