toilet lower than sewer / septic outlet

[Dan_574]

has anyone ever installed a toilet lower than the sewer outlet and used a macerator pump set up?

I want to install it downstairs just as a second toilet for when we're outside, the outlet is more or less level with where I want to put the toilet but its about 20m away.

I ve looked at 1 product by sani pump, that will do the job but at $1150 its way more than I want to spend.

If anyone has any other ideas, suggestions or products, let me know. Cheers

Could you use a P trap toilet perhaps?

If the outlet is level with the toilet just raise the floor in the loo so there is fall

I thought about set it up on a floor but its already off the ground on a small slab where the stairwell is, theres a diagram below. Its under the house where the garage is so I cant run pipes just off the ground. what fall would you use 1:200

As long as there is fall all the way along the piping it will work.
