Can you use a wye instead of a sanitary tee?
When connecting any vertical waste drop to a horizontal run the proper way to do it is to either use a Wye & 1/8 bend (45 deg), or a Sanitary combo. A sanitary combo is a combination Wye & 1/8 bend already made in one fitting.
When would you use a sanitary tee?
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.
What position must a sanitary tee tee Wye be installed and why?
A Sanitary tee is also used in place of a vent tee when plumbing vent lines. It helps maintain the proper flow. When using a sanitary tee, don’t lay it on its back with a side opening because this will result in an upstream splash of waste which creates clogging inside the line.
What are the advantages of using Wye over tee fittings for wastewater systems?
A wye is similar, but instead of having an opening at the bottom, it has a Y-shaped branch with an opening on each side of the Y shape. This makes it easier for multiple lines to connect into a single line without one tee fitting.
Can a sanitary tee be used horizontally?
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.
What is the difference between a wye and a tee Wye?
Sanitary tees are used to connect horizontal lines to vertical lines. But wyes are used to connect vertical lines to horizontal lines. You can also use wyes to combine or split horizontal lines.
Can I use a wye horizontally?
Yes, it is/has been done often. If you can, I personally prefer to put the wye so that the offshoot is angled slightly down into the main run to create a natural direction for flow.
Can you use a wye fitting vertically?
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.
Can you use a sanitary tee on its back for venting?
Sanitary tee can be on its back for dry vent, but the vent has to be a vertical dry vent.
How do I connect two horizontal drain pipes?

Can a drain vent pipe be angled?
Plumbing vents need to be straight on the vertical. This is necessary to avoid any vapor locks from occurring. When there is a bend in the vent pipe, moisture accumulates and is trapped.
Which direction install sanitary tee?
If you are using a sanitary tee to go from a horizontal vent pipe into a vertical vent the correct orientation is “upside down” from its normal usage. The curve of the tee should go from the horizontal direction curving up toward the roof.
Can I use a sanitary tee for sink?
Although a horizontal-to-vertical use of a sanitary tee under a kitchen sink (as shown below) is a less likely to cause a drain problem, it is also not a rated application. A 90º double tee is also the correct fitting here.
Can you use a sanitary tee as a vent tee?
Use a sanitary tee to connect a horizontal trap arm to a vertical drain and vent. The sweep on the santee must face down so that it sweeps toward the drain. Glue the tee inlet to the trap arm with plastic pipe cement, and glue the drain and vent to the two vertical barrels.
Is there a fitting called a cross sanitary tee?
Double Sanitary Tee (Sanitary Cross) – Similar to a cross. This fitting differs from a supply cross fitting in that two of the ports have curved inlets. The fitting has been used in the past for connecting the drains of back-to-back fixtures (such as back-to-back bathroom sinks).
Where can I use double wye fitting?
A double-wye fitting may be used in horizontal drain lines. The use of 1/8th bend elbows at the outlets of the double-wye fitting to form a double-combination pattern is acceptable. The minimum slope of the barrel of the fitting shall be “/-inch per foot.
How do you join two pipes at right angles?
