Can I install a saniplus toilet in my attic and pump down 10 feet and 100 feet to my septic tank?

Hi Gilbert...

I'm sure you can do what your propose, but why would you use an electrical device (pump) that will periodically require maintenance and replacement when you can just let gravity do the work for free? Please explain, OK?

Thanks...

Mostly because the toilet un the garage attic is 100 feet away.

Toilet could be 200-300 feet away from the septic... fact remains that as long as the pipes are pitched as required by code (1/4" pitch per foot for 3" or smaller pipe) the waste will reach the septic tank with no problem... ;)

If you can pipe this up via gravity (without pump) then that is the way to go, OK?

Glad to discuss more if you want...

Does the 3" septic pipe have to be 4' deep to prevent freezing?

No, not in most cases, as long as the pipe is pitched to the septic tank as mentioned earlier, waste water will flow by gravity into the septic tank/field and will not freeze.

Some areas (including mine) require minimum four foot bury for sewer lines and seven foot bury for water lines. Check with your local inspector for local codes. I have run across many a frozen sewer due to a leaky flapper valve on a toilet or a drippy faucet when the sewer is not deep enough to prevent the very small flow from freezing and building an ice dam in the sewer.
