When the toilet drain reaches a vertical wall, it drops straight down between wall studs. 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.

The minimum fall for a waste pipe is 1 in 40. The maximum fall is 1 in 110 (apart from vertical pipes but that’s a different story). So pipes with a gradient between 1 in 40 and 1 in 110 should have adequate flow to prevent blockages from occurring.

How do you unblock a toilet stack?

Insert a plunger into the bowl pushing it to the bottom. Attempt to plunge the toilet to unblock the soil pipe. If the obstruction is near the top of the soil pipe, simple plunging may free it. Watch for the water to recede out of the bowl and down the soil pipe.
