Plumbing Vent System Distances & Routing
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.
The usual slope on the fixture drain piping is 1/4″ of slope per 12″ (foot) of horizontal distance or “run” of piping.

Should I put sink in kitchen island?
If you don’t want a range hood hanging down into the middle of the space, put the sink on your island instead. If you’re interested in making your island a cleaning station with a sink, don’t forget the dishwasher should be included too. Decide whether the dishwasher should be on the left or the right of the sink.
How do you check a vent pipe for blockage?
Use a flashlight to shine a bright light down the vent pipe to look for further blockage you can reach. If you can see but can’t reach, run a plumber’s snake down the vent pipe. To continue, feed the end of a garden hose down the vent and have someone on the ground turn on the water.
How does a loop vent work?
The loop vent allows gas to flow up the pipe as the water flows down the pipe. The loop creates a vacuum that pulls gas away from the water as water runs on the other side. a loop vent allows this to happen without needing a flat vent.
How far can you run a drain without a vent?
When builders look only at the table without reading the text, they find that a 2-inch-diameter drain can run a maximum distance of 8 feet to the vent.
Does the vent go before or after the P trap?
Plain and simple, the vent comes AFTER the trap. A vent before the trap does absolutely nothing. The open drain inlet at the bottom of the sink is the vent before the trap. It is why fixtures do not need ANY vent to drain, they need a proper drain to not siphon the trap.
What is a good size kitchen island?
The average size of a kitchen island is about 3 by 6½ feet (1,000 by 2,000 millimeters). This would typically have a surrounding clearance zone of about 40 inches (1,000 millimeters). But an island’s size is usually determined by the distances around it, so it makes sense that larger rooms can allow for bigger islands.
How much space should be between kitchen island and cabinets?
The NKBA Guidelines
At least 36 inches should be provided for walkways between an island and counter. If the counter space contains a work area and appliances such as a sink, stove or dishwasher, the work aisle should be 42 to 48 inches wide.
Where should sink go in kitchen?
If this is the case in your kitchen, consider hiring a plumber to relocate the plumbing to accommodate the best placement for the sink. Regardless of your kitchen’s size or layout (L-shaped, galley, U-shaped or island), the sum of all the legs in a work triangle should not be less than 10 feet or greater than 25 feet.
