Divine Can A Plumbing Vent Run Horizontal
Yeah but as Dave pointed out vent stacks dont usually vent they draw.
Can a plumbing vent run horizontal. You quoted it correctly that the vent must be 6in. I already reduced the 4 to 3 about 6from the toilet. In other words any water that gets into the vent pipe opening must be able to run freely all the way to the sewer without creating a trap.
Others dont consider this important. Ensure that any water that gets through the vent opening can run out to the sewer without blocking the flow. It connects to a 2-inch tee against the wall.
If a plumbing fixture is located too far from the main building vent stack then its own drain pipe must have its own vent stack connection piping. Some inspectors prefer horizontal vent pipes to be sloped so condensation can run back to the drainpipes. It can attach directly behind the fixture or to the horizontal drain line.
The usual slope on the fixture drain piping is 14 of slope per 12 foot of horizontal distance or run of piping. When a minimum-sized vent is increased one 1 pipe size for it entire length the maximum length limitation does not apply. The X measurement with upc code would be from the vent to the flange six feet or less The vent horizontal could be 13 the vertical.
The picture show a plumbing vent in the attic. The vent runs horizontal for 20 - -25 feet across the attic to the vertical pipe that goes through the roof. They run upwards and over the main vent.
The horizontal white PVC pipe at the bottom of the photo held up by the j-hook is a drain pipe for a shower. In other words any water that gets into the vent pipe opening must be able to run freely all the way to the sewer without creating a trap. So if you had 24 feet of vertical your horizontal could be 8 feet.
