What is the fall on sewer pipe?
The plumbing code requires drain pipe to be sloped at a minimum of 1/2 inch per foot and a maximum of three inches per foot or vertical. A slope of less than a quarter-inch per foot will cause a lot of drain clogs and a slope of more than three inches will allow the water to drain.
How big of a drop do you need for a toilet drain?
If the slope isn’t steep enough, waste materials won’t drain off adequately, and if the slope is too steep, the liquid can outrun the solids, leaving them sitting in the middle of the pipe. For a standard 4-inch drain line, which is the typical size for a toilet drainpipe, the minimal drop is 1/4 inch per linear foot.
How big is a drop in waste pipe?
Having had some “ishoos” with slack drains, I might make it a bit steeper for luck. a 1 in 40 drop is 25mm drop in a 1 metre run. To measure that, I have a standard 1 metre long level, and I tape a small bit of 2*1 timber to one end of the level, then set the pipe so the level reads level and you have a 1 in 40 fall.
How big is a standard toilet waste line?
Toilet waste lines are often 3″ or 4″. All the fixtures in your house will connect to a main drain line, which is usually 4″ in diameter. If you need to know the thickness, outside diameter or inside diameter of a PVC pipe, check out this calculator. Next, measure the length of the pipe you are working with.
What is the slope needed on toilet pipes?
Every house has a vertical waste stack that extends down to the main sewer, and toilets tie into it by branch lines that are, in most cases, almost horizontal. One of the rules of plumbing is that waste flows downhill, so the branch lines have to have a slope, but it can’t be too steep.

Can a vertical drop be used in a toilet?
Although this is a vertical drop, don’t use standard 90-degree plumbing elbows, called “hard 90s,” to connect the pipes. The sharp corners on these elbow fittings can increase the risk of clogs.
