Elevate the toilet to run the drain?


the planned toilet drain is right above two big beams. One solution i thought about was elevate the floor to get some room to make some turn of the drain so i can get pass the beams.

So my question is, is this the way to do it? if so, how tall should i elevate the toilet floor? do i only turn 45 degress to avoid the beam?

Elevate the toilet to run the drain?


Let's answer the question "can a toiler be elevated"--Yes. I have done this. The situation was a basement where the floor level was higher than the septic tank. In order to get the proper slope and not to have to bust up concrete we created a "throne" for the toilet. This was an area approximately 6' wide x 4' deep, wall on one side, elevated tub on the other. Darn thing worked out pretty well. I would stay away from cutting the beams if possible. I don't see why you could not use a short stub (nipple) after the toilet flange, then a 45, another nipple, another 45 into the straight run. Use long sweep 45 ells if you can get them, makes the flow better on waste line. David

I can't honestly advise you without some sort of diagram.

DO NOT touch that beam. Under no circumstances.

Elevate the toilet to run the drain?


The basement bathroom in the house I currently live in had a 'throne' raised about 8 inches and worked fine.
During a slack yime in my schedule a couple of years ago, I busted out the concrete to add a shower stall and re-plumbed the toilet, so I can't measure the height.
The beam should not be cut or notched without advise from an engineer following an on-site inspection.

I'm with Alan..any pics or diagrams? Don't tamper with the beams. Worst case scenario is that you will have to construct a bulkhead in the floor below to accommodate the waste pipe. Not sure about where you are but here we have a 'guideline' of 1/4" for every 3 feet for an above grade 3" pipe...but the more the merrier.

i wouldnt use 45s ,too much slope in a short area seperates liquids from solids and will cause you grief later

Intersting post plummen..can you expand on that? I would think that more slope is good. 45 degrees seems gradual enough.

normally 1/4" per foot is about right for most interior plumbing.
if the liquids run away too quick the solids tend to build up,or so its been beatin into my head for last 30 years anyway.on a vert short run going directly into a stack it may not be so bad but on long stretches i think it would settle out easier.

Elevate the toilet to run the drain?


The throne idea reminds me of a house I looked at. Up a short flight of stairs, 3-4 feet above the basement floor sat a toilet on a wooden deck. I didn't try it out but it looked like if you stood up you would hit your head on the suspended ceiling. There were no other fixtures, just a toilet. The realtor actually listed it as a 1/2 bath. The story goes, the current owner liked to work in his basement shop but did not want to goe upstairs to use the john. I guess he kept some waterless hand cleaner nearby as well.

well, it is a beam and a joint.


what the plumber did was, notched a bit out of the beam (oversized beam anyways, 12"X12" for a 30' span), and used a tilted flange. No elevation used in the end. The tilted flange is usable?
