capacity of the tnak

[Mitch]

hi ron,
what is the capacity of the tnak you are using. the smallest i can find around town would be a 1/2hp jet pump with a capacity of 11lts per hour. if i were to use this pump for a system you have designed, do i have to install a foot valve at the inflow pipe ?

Not sure what a jet pump is but you might need more than a foot valve. You might need a yard valve.
I use a 120 to 200 GPH (gallon per hour) Submersible Pump depending on the size of the garden.
