I'm running a drip system from the faucet in my garage to a second
story balcony. What I have is some 1/4" tubing that goes directly from
that faucet, up one length of the garage door, across the
length of the garage door (two car garage), down the length of the
garage door, out the garage to a patch of dirt, up a tree that brushes
against my condo, extending along a branch finally entering my
balcony, up to a flower bed - whew......
okay...Now, I have enough pressure to water two flowerbeds - 4 drip
sprinklers. I want to add three more pots and know that i won't have
the water pressure to do so.
The total distance that the tubing covers, from the faucet to the
flowerbed, is around 50'.
I have issues here with the homeowners association so I have to keep
things as stealth as possible - that's why I chose to use the 1/4"
instead of the 1/2" tubing.
Soooooo...in an effort to gain a little more water pressure, I was
thinking of re-tubing the lengths on the inside of the garage - up,
across, and down with the 1/2" tubing.
I guess what I'm looking for here is someone kind enough to help me
with some calculations...
My constants a Water pressure, distance from the faucet to the
flowerbeds, and the height from the ground floor to the second story.
Variable(s): The inside diameter of the tubing.
I'd like to know if I could increase the water pressure by "cutting
down" the amount of 1/4" tubing (closest to the faucet) that I'm using
and instead replacing it with the 1/2" tubing. The total length of all
tubing with still be the same - still 50'. The height that the tubing
travels would also still be the same and so would the starting water
pressure (whatever that happens to be).
Say for example I now have:
50 feet of 1/4" tubing from water source to flower bed and that I
get a water presure reading of X.

If I use 20' feet of 1/2" and 30' of 1/4" should my water pressure
increase?
Faucet]===20' of 1/2" tubing===][==30' of 1/4"==]flowerbed
If I use 40' feet of 1/2" and 10' of 1/4" will my water pressure
increase even more?

Thanks...
