How far can a 2 inch drain run from a table?
This basic scientific statement always trumps the simple length taken from a table and is the real key to preventing a situation where a siphon could form. 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.
How far away should a vent pipe be from a drain?
Your household plumbing works similarly. The ICC organization's plumbing codes state that there should be a vent pipe within five feet of any drain. With your new location 35 feet away from the main stack (which is of course vented), you're too far away from that one, so you'll need to tie into another vent stack.
Can the kitchen sink be too far from the drain?
The kitchen sink can be set as far from the drain as you want it to be. But the question is, will it be effective? We think not. Before you decide where you want your kitchen sink to be, check if the drain connectivity to that place is active or not.
What is the maximum length of a 3/8 inch drain?
But if the drain is sloped at 3/8 inch per foot, the maximum length is less than what someone might assume with just a quick glance at the table—it is actually 5.33 feet: 3/8 inch x 5.33 = 2 inches. So the additional slope of just 1/8 inch per foot reduces the allowable drain length between the trap and vent by a whopping 2.66 feet, or 33%.

How far can a sink be from the main stack?
1. Install the vent between the sink P-trap and the point where the waste line leading from the trap drops to the main sewer. If the waste line has a diameter of 1 1/4 inches, the vent can be no farther than 2 1/2 feet from the trap. If the waste line is 1 1/2 inches, this critical distance is 3 1/2 feet.
How far can you run a waste pipe?
By increasing the size of the pipe, you can place the fitting further away – typically between 3 and 4m away for a 50mm pipe. If you exceed these dimensions there is a risk of the trap 'pulling', wastewater, which would allow foul smells into the room through the empty trap.
How far can you run 1 2 water line?

Wider drain pipes have a larger surface area. This has a positive effect on a drainage system because it reduces the pressure in the pipes.

Why is a siphon created?
If the entire cross-section of a drain is able to fill with water downstream of the trap, a siphon can be created for a sufficient period of time to pull enough water out of the trap to render it ineffective. A vent is supposed to maintain air in the cross-section of the pipe to prevent a siphon from forming.
How long is a 3/8 inch drain?

So the additional slope of just 1/8 inch per foot reduces the allowable drain length between the trap and vent by a whopping 2.66 feet, or 33%.
What is a trap in plumbing?
Basically, it’s a simple cup of water that keeps sewer air from communicating with the air you breathe. The trap arm is the portion of a fixture drain between a trap weir and its protecting vent. The trap weir is the point at the bottom of the trap arm pipe where it connects to the trap. It’s the height at which water will no longer flow from the trap via gravity—the rim of the cup, so to speak (see “How Siphons Are Created,” below).
How much slope can you use for a pipe?
It’s stating that you can only use up to an 8-foot length if the pipe is run at the minimum allowable slope of 1/4 inch per foot. But often, installers don’t install pipe at the minimum slope, just as they wouldn’t stand at the very edge of a cliff to enjoy the vista. (For many code applications, I use that analogy to encourage people to build beyond the minimum level that is allowed.)
How far can a 2 inch drain run?

They may also see that the slope column references 1/4 inch per foot, but they are likely to assume that it’s just reiterating the minimum allowable slope for a 2-inch drain.
What is the maximum trap arm?
The section of the code that pertains to the maximum trap-arm (also called a “dirty arm”) length has strict provisions designed to prevent a siphon from forming in a drain. For simplicity, the maximum distance between a trap and its protecting vent has been presented in the form of a table for decades.
Where is the weir on a trap?
The trap weir is the point at the bottom of the trap arm pipe where it connects to the trap. It’s the height at which water will no longer flow from the trap via gravity—the rim of the cup, so to speak (see “How Siphons Are Created,” below). Click here for larger image.
