What is a tee Wye in plumbing? Wye (Y) fitting It is a waste-fitting tee in which the side inlet pipe enters at a 45-degree angle. The connection is typically at a 45-degree, rather than 90 degrees; if a branch turns out further at the end to 90 degrees (perpendicular), the fitting becomes a combo tee.

What is a wye and a sanitary tee?
In order to do this, you will need to know what a sanitary tee is, what a wye is, and how to use each one. A Wye is shaped like a ‘Y’ and is used to combine two different lines into a single horizontal line which then maintains flow without any clogging problems.
What is a wye in plumbing?
In other words, it connects your horizontal piping to a vertical vent or pipe. If you use a wye, this Y-shaped drain fitting is meant to be used horizontally. In other words, they attach a vertical pipe to a horizontal pipe.

The connection is typically at a 45-degree, rather than 90 degrees; if a branch turns out further at the end to 90 degrees (perpendicular), the fitting becomes a combo tee. Click to see full answer. Also know, what is the difference between a sanitary tee and a Wye? Connections to horizontal drain lines should be made with wye (Y) fittings.
What is a sanitary tee in plumbing?
A sanitary tee directs traffic in your home's drain-waste-vent plumbing system to make sure wastes go down to the sewer and gases go out the vent stack. In some cases, a sanitary tee is used in place of a vent tee for plumbing vent lines—then, the branch sweeps upward instead.
What is the difference between a tee and a Wye?
Although a wye or tee may superficially appear to perform the same job of redirecting flow by 90 degrees, their performance is not the same. In a wye or long-sweep 90 the flow is positively directed in a specific direction. But in a tee there is not a smooth flow transition at the junction.
What is a wye fitting in plumbing?
A fitting or adapter refers to a device that joins straight sections of a tube or pipe. They can adapt to various shapes or sizes and are used for multiple purposes, for example, maintaining or measuring the flow of a fluid.
Where is a Wye or sanitary tee used?
A sanitary tee should be used when connecting a horizontal run, such as a waste arm to a vent stack or vertical riser. “If you think it's expensive to hire a professional to do the job, wait until you hire an amateur.”
What does a tee do in plumbing?
A sanitary tee is a plumbing fixture that allows liquids to drain while also allowing the plumbing system to vent. The fitting resembles a normal tee fitting; the sanitary tee, however, when viewed from the side will have a definite downward sweep to the center inlet.

Can you use a wye for drain?
Connecting a trap to a vertical drain with a wye fitting and a 45-degree elbow seems like a good idea. But it's not. As water drains down the steep slope at the wye, it can create a siphon effect such that water will be sucked out of the trap. And the empty trap will allow sewer gas to flow into your home.
What are the advantages of using Wye over tee fittings for wastewater systems?
The benefits of using Wye are numerous; it reduces the risk of clogging, saves time cleaning out your pipes, and helps with water conservation because there's less waste going down the drain.
Can you use a wye fitting vertically?

What is the difference between a tee and an elbow?
Elbows and tees are common types of fittings, and both are used to change the direction of a pipe.

What is a double wye used for?

Plumbing Wye vs Sanitary Tee: Things to know
Plumbing wye is generally used when connecting the horizontally to the vertical planes. It has a standard Y shape that simultaneously connects three pipelines sequenced.
Plumbing wye VS Sanitary Tee: Key Differences
You may think it is pretty easy to differentiate sanitary tee and Plumbing wye because of their shape.
Conclusion
Drainage system performance is closely connected with the proper installation of the sanitary tee and plumbing wye to ensure proper vent and flow of solid and liquid. But you may mess between them, install the wrong part, and face drainage problems.
Why do snakes use long sweeps?
Long sweeps are easier to run a snake through and drain better as the water path is gradually changed (if you have the space to use them). This is a sanitary tee and can only be used as shown in the vertical orientation. They are only used to go from the horizontal to vertical plane.
Can you use a sanitary tee in vertical orientation?
This is a sanitary tee and can only be used as shown in the vertical orientation. They are only used to go from the horizontal to vertical plane. If used flat (horizontal) they are prone to clogging. You must use a long sweep or wye+⅛ for horizontal DWV. Share.
Is a sanitary tee legal for venting?
1. A sanitary tee is legal for drainage in the horizontal to vertical position, however it is legal to use a sanitary tee in the hotizontal position when used for venting.
What is the difference between a sanitary tee and a Wye?
Connections to horizontal drain lines should be made with wye (Y) fittings. The fitting called a “ Sanitary Tee ” looks like it could do the job, but it doesn’t. A sanitary tee cannot be laid on its back, horizontally: It is shaped differently than the wye and should only be aligned vertically, or it may block up.
When can you use a sanitary tee?
A sanitary tee should be used when connecting a horizontal run, such as a waste arm to a vent stack or vertical riser. “ If you think it’s expensive to hire a professional to do the job, wait until you hire an amateur.”
What is a wye used for?
A standard wye is a Y-shaped fitting which allows one pipe to be joined to another at a 45° angle. A wye may also be used to split a branch line equally in two directions, such as the splitting of a main line into two smaller branches.
Can you use a sanitary tee for toilet?
You can ‘t use a tee, and you must have a vent between the connection and the toilet. Otherwise when another toilet is flushed, and you are sitting on the toilet, the “whoosh” may go the other way and give you a wet surprise.
Can you put a 90 in a sewer line?
You should design your wastewater pipes in a similar manner, for the most part. 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. All drain lines should have a minimum fall of an eighth of an inch per foot of horizontal run.
Can a sanitary tee be used horizontally for venting?
Sanitary tees may only be used on drainage piping when transitioning from horizontal (1/4” per foot) to vertical. All others must sweep in direction of flow with proper drainage fittings.
Does a vent stack have to go straight up?
Vent pipes must be installed so they stay dry. This means that they should emerge from the top of the drainpipe, either straight vertically or at no less than a 45-degree angle from horizontal, so that water cannot back up into them.

FAQ
- Can You Lay a Sanitary Tee at its Back?
Never lay the sanitary tee on its back with its side opening; it will create a big issue.
