I wouldn't sweat it, I've got more bends than that, and 10 feet of head, and I'm not having any trouble.

i had it in working fine for 6 months till the guys kid tryrd to flush an athletic sock. jammed it.  now the grandad has determined that it wasn't the sock that we pulled off the pump but the 90's . i am looking for some kinda reference source that i can use when i tell this holy roller grandpa to cram it.heck it pumps so well that i was running the washer the shower the vanity and the dishwasher while flushing the toilet with no trouble.

the discharge pipe on your sewage pump is 3/4" ?!?! that is incredibly small pipe for any type of household drain. Usually pump up toilet systems use 1 1/2"-2" discharge pipe. 90's aren't that bad but they will restrict the flow somewhat....but they aren't nearly as restrictive as socks jamming the pump! shocked

I concur with G_P. 1-1/2 inch minimum I.D., and use sweep ells if at all possible. Otherwise cleanout will be a <cough> challenge.

its one of the new style of pumpup toilets  its designed to use the 3/4 inch line with a macerator pump.they are right handy for remodeling where its hard to get larger pipes in.  the total run before it dumps into main soil stack is about 4 foot. its rated for 16 feet of lift and over a 100 feet of run.

Yeah I can see where macerating a sock might be a challenge, no matter the size exhaust.

pressure is more relevant on the input side

on the output side, its more about velocity

the velocity is what the 3/4 inch pipe is about. the stuff really moves through it.

I would imagine it would! 3/4" pipe on a sewage pump is going to make a pressure washer style jet of poop!
