With that distance it will be fine.
Have a 1950s (6gallon?) toilet (Crane) on even older septic system. I am wondering if a modern 1.6 gallon toilet will work with this old system. here's the existing setup:
From upstairs toilet, waste pipe has a vertical drop of about 12 feet to right angle turn , then pipe goes horizontal about another 12 feet to another right angle turn, then a horizontal straight run of almost 30 feet out of the house and continuint straight another 20 feet or so to the concrete septic tank . Its about a 1930ish system.
Just wondering, if I replaced the old fashioned toilet, if the new modern low flow toilet would have enough water discharge to flush things out to the septic tank ?
The existing system as is works fine and always has, but eventually want to put in all new bathroom fixtures.
The toilet does NOT care where its waste is going. If it will work with a 100' line to a city sewer, it will work for a septic tank.

Everyone, thank you for the answers. Will check out the modern fixtures knowing this.
Just keep in mind, low flow toilets are not equal. Do heed the advice on Terry's web site.
