Is the sink connected to the toilet?

Depending on the configuration of the main plumbing pipes in a house, the sink drain may tie into the toilet waste pipe that extends from the toilet to the main soil stack. If the toilet is far enough from the stack, the sink drain may also be acting as a vent for the toilet.

Similarly, how does a toilet connected to the drain?

A toilet has two main parts—the tank and the bowl. The bowl holds water and connects to the drain for disposing of waste water and waste. When the tank's water rapidly drops down into the bowl (upon a flush), the pressure causes the bowl's waste water to go down the drain.

Beside above, can a toilet drain have bends? To achieve good water flow, try to install horizontal drain pipes so they have a minimum of 1/4 inch per foot slope. Sharp bends in piping also slow down water movement. They cause the moving water to loose energy. The 90 degree bends also are tough to pass through with drain cleaning equipment.

People also ask, do toilets and showers use the same drain?

Here's the longer answer: Your shower and toilet most likely share a drain line and a vent stack (this setup is called wet venting, more on that later). If either the line or the stack has a clog or blockage, air is forced either up or down your toilet, making the gurgling noise you're hearing.

Can a shower and toilet share a vent?

So yes the shower can also be vented by the wet vent along with the toilet. There is one major stipulation when wet venting multiple fixtures when a toilet is one of them: the toilet must be the last fixture connected to the wet vent.

How far can a vent be from a toilet?

Tie the waste line from the new toilet directly into the stack if the toilet is within six feet of the stack and the waste line is 3 inches in diameter. If the waste line is 4 inches in diameter, the toilet can be as far as 10 feet from the stack.

Can two toilets share the same drain?

Most houses have more than one toilet, and if they are on the same side of the house, their waste lines can usually tie into the same stack. If they are on opposite sides, however, each may need its own stack. Since the stacks must be vented, this would mean two vent openings on the roof.

Where is the trap in a toilet?

A toilet trap, or trapway, is a curving channel inside the base of a toilet that leads from the hole at the bottom of the bowl to the drainpipe. When a toilet backs up and the clog did not occur in the drainpipe, the stoppage usually exists in the trap.

Can you add a bathroom anywhere in a house?

Can you add a bathroom anywhere in your house? The short answer is yes, you can install a bathroom almost anywhere that you can afford it. However, this will largely depend on your plumbing and electrical setup and what style of bathroom you want, which goes into another common question.

Do plumbing vents have to go through the roof?

Alternative to a Roof Stack
All the vents connect to it through branch lines, and it vents the main toilet, the most important plumbing fixture in most houses. If you can't put the main stack through the roof, most local plumbing codes allow you to put it through a wall instead, but there are conditions.

Does shower water go to sewage?

Wastewater” is any water that's been used. You flush wastewater down a drain, either in a sink, a tub or shower, or toilet. Drains work by using simple gravity.

Can you rotate a toilet?

Turning the toilet so it angles further from any surfaces is a potential solution. Because the toilet is connected to the drain through a flange, you must rotate the flange to reposition the toilet.

When I flush my toilet it comes up in my shower?

When you flush the toilet, water backs up into or comes up in the tub or shower. When your sewer line is clogged, the water can't go down the drain. Instead, it flows back up the pipes and comes out at the lowest point — usually the shower drain. Run the water in the sink closest to the toilet for about a minute.

What happens if I poop in the shower?

Fecal matter would pass through a shower drain if the P-trap is made of 2” ABS, but the amount of water and velocity might not be enough to make it pass through. If the shower drain is steel or cast iron, or if the drain is not completely clear, all bets or off, use the toilet.

Can one clogged toilet affect another?

If you have a clog that is related to only one fixture (meaning the clog is only affecting one drain, not multiple,) this means it is only a branch drain clog. If you have a clog that is affecting multiple drains or is backing up into another drain, this usually signifies the clog is deeper down the line.

Can a vent pipe have an elbow?

Use wide-radius elbows for drains to keep the flow of water at a consistent speed. Note: You may have vent piping, but you still cannot use the tight 90-degree elbow -- sometimes called a "vent elbow" -- if the joint is below the water level, which is usually at the level of the sink.

Is 3 inch pipe OK for toilet?

In new construction, 4-inch drains can be installed from every toilet, or you can run a 3-inch drain line from a toilet to the home's main 4-inch drain pipe -- the line running from the house to the sewer or septic system. Older homes may have only 3-inch drains, so that's what you have to work with.

How much drop does a toilet need?

Standard Drop
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. That means that the pipe should drop an entire inch every 4 feet.

Can you put a 90 in a sink drain?

It's a bad plumbing practice to have a hard 90-degree bend in a horizontal drain line that's buried in a slab or otherwise hidden. If you have to make a 90-degree bend, use two 45-degree fittings and put a small piece of straight pipe between the fittings, if possible.

Can you use a 2 inch pipe for a toilet?

When combined with a laundry tub, the drain pipe must be a minimum of 2 inches in diameter. And toilet requires a drain pipe of 3 inches in diameter, unless two toilets are on the same drain and then it must be a 4-inch plumbing waste pipe. The stack discharges into the main drain pipe.

What is a toilet closet bend?

A closet bend is the curved section of the length of a drain pipe that is found just below the toilet. A closet bend is usually made in an elbow shape, allowing the exit flush of a toilet to go out at a 90 degree angle horizontally along the wall. It is the last fitting of a drainage system serving a toilet.
