Need help with drip system

Hey everyone , thanks in advance for the help .
here’s my issue.
I have 2 4x4 tables with 169 3.5x3.5 square pots on each table Filled with clay pebbles
I have a 1700gph pump . 1/2” maim tubing running from pump to 6 1/2 tubes running the length of table . With 29 1/4” drip lines on each 1/2” pipe .
I’d like to run the lines open with no emitters or droppers to not have to deal with clogs when the table is full .
the issue is I don’t have enough pressure to get the water to flow from all the sites .
do I just need a bigger pump or am I missing something in the design of the system .
Thank you , any help would be greatly appreciated

I don't do drip systems myself, but I believe you need to research "manifold(s)"...basically a tube/container that holds equal or more water then the combined volume of all tubing going to your plants.
So say you use 4 X 1/4' tubes at say 3" to run the water to the plants...you would need 1" manifold at 3', minimum.
In your setup you would need a larger manifold or you could also maybe do multiple manifolds.
Hope that helps some.
Best of luck and happy growin'

lift can be an issue, if possible could you put the reservoir up on a table or something? Maybe that would allow you to see if the pump is the issue

You need a manifold and a pump with high lift
Your pump may be a billion GPH @ 0 lift and 1gph at 2 feet
