Horizontal run out of sewage pump?

[Bets]

This is my spouse and I's first below-grade bathroom challenge. We've done pretty much every type of construction and remodeling except putting in a basement bathroom. And it's definitely kicking our butts! Any advice is appreciated.

Problem: We're putting in a basement bathroom (sink, toilet, and shower). Our main line runs from the stack into the ground. We tore up the slab and found out that the slope from Point A (where we want the bathroom) to Point B (main line) was not enough to allow for 1/4 inch per foot. It's practically even. In an effort to solve the problem, we went out and bought a sewage pump. Our goal was to run the sewage to the pump, then have the pump send the sewage horizontally to the main line. The horizontal run would be about 5 feet and a 1 foot slope. Well, after doing some Googling, I'm torn. People are saying that the check valve should be installed vertically. But what we really want is to do a 45 degree, attach the check valve, then continue to the main (see pic) horizontally. I'm torn because it has a lot of push power-- Everbilt 1/2 HP Sewage Pump, capable of 2" dia solids.

What are your thoughts? Is it okay to 45 degree? Suggestions appreciated.

FYI-- we're planning on burying the pump basin like normal, but sinking it a little lower and having a hatch area for maintenance. That's why there's that box area around it in the picture.

The check valve is to hold discharge from backwashing back into the sump from the vertical rise of the discharge.
if the vertical rise of the discharge is only 1 foot then the check valves only real function would be if the main line backed up and would possible prevent your basement bathroom from flooding.
Anything on the pump discharge line after the line has positive grade is really not a issue fro the check valve, again, unless the main backs up.

drains or vents 45 or more from horizontal is considered vertical. less than is considered horizontal
so installing a check valve at 45 degrees would be considered Vertical

Who says the check valve should be installed vertically?
I suppose many of the pump companies may have sewage type check valves that have been designed to be able to function vertically. However, there's absolutely nothing wrong with a horizontally mounted swing check valve that has been designed for it. In fact I was under the impression that horizontal or a maximum angle up to 45 degrees from the horizontal was recommended for systems handling solids.

I suppose vertical arrangements were preferred since most cases the discharge pipe wants to rise vertically.

I assume you are following plumbing code for sump pump system.

They just like ya to mount it vertical. But if you take note to put the hinge up then the normal resting position will be closed is the big thing.

The majority of my experience was designing various plumbing systems for water and wastewater treatment plants, as well as a number of other related facilities. I designed more solids handling sump pump systems, for more different applications then I can remember. But one thing I can remember is, I never used a vertical check valve. Of course we were always dealing with metal piping and fittings and not plastic. That probably made a bit of a difference.

spring checks are for use in a vertical pipe and swing checks are to be used in a horizontal pipe
you can use a spring check, it is not against code to do so.
it is against any type of damn common freaking sense you might of had at one time in your life.
OMG OMG OMG !!!!
WHAT DIS THE CRAZY MEAN MEAN BY THAT ???? OH SWOON !!!!!!!!!!!!

Swing check, utilizes a gate that is pushed open then falls back closed,
Spring check, Uses a spring and a rubber diaphragm
and when used in the horizontal , toilet paper and crap gets caught on the spring, no big deal if you do not mind removing it and cleaning it every year,

Holy mackerel!
Well I had a good laugh.
It is easy to get swing and spring check valves confused, but they do serve different purposes.
nugh said!
