View Full Version : return plumbing

i have a drilled tank , with 1 inch bulk heads..

all the plumbing is 1 inch.

the return pump is a mag 9.5 with a 3/4 inch outlet.

my poor fluid dynamics skills tell me that double the pipe is half the pressure. or something like that..

so , the pipe, up into the bulkhead, into the tank..

if i adapt my 1 inch retrun down to 1/4 or 1/2 or something... inside the tank...

this should blast the water harder into the tank right? aka a thumb over a water hose effect...

or am i way off?

if this isnt a terrible idea, should i take it to 1/2 or 1/4

It will have that affect, but with head loss and decrease in pipe size...lots of stress on pump and decreased flow.

so what im hearing,

is i can, and maybe should consider adapting the inside the tank size back down to the original 3/4. this would up my water pressure and not torture the pump any more than it was designed for....
