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.

What is a combo in plumbing?

A sanitary combo is a combination Wye & 1/8 bend already made in one fitting. The reason to form a long radius bend to insure the waste is directed in the downstream direction as it enters the horizontal run.

Can a toilet drain have a 90?

The 90 degree bends also are tough to pass through with drain cleaning equipment. Never install a 90 degree fitting under ground except when used at the base of a vertical plumbing stack. If you have to turn 90 degrees, use two 45 degree angle fittings separated by a 12 or 18 inch piece of straight pipe.

Can a double wye be installed horizontally?

quote; The double fixture fitting can’t be used on the horizontal. It is NOT a back to back fixture fitting.

Can sewer vent run horizontal?

To answer your specific question, yes, vent pipes can have horizontal runs, as long as there is no possibility of them becoming plugged with water. In other words, any water that gets into the vent pipe opening must be able to run freely all the way to the sewer, without creating a “trap”.

Does a sewer line have to be straight?

Normally they run level or plumb, unless there is an obstacle to work around. 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.

Can plumbing vent pipes have 90 degree angles?

You can install 90-degree bends in vent pipes. … Plumbing vent pipes are used to allow fresh air into the plumbing system and help the other drains in the house work properly. This means that there are bends or connections in the other piping and this piping needs to attach to the venting system.

What is a wye used for?

A fitting with three openings, a wye joins (or creates) branch lines. It is a waste-fitting tee in which the side inlet pipe enters at a 45° angle. A standard wye is a Y-shaped fitting which allows one pipe to be joined to another at a 45° angle.

Can you use a wye 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 put a 90 in a sewer line?

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. It’s fine to have a larger-radius (sweep) 90-degree bend at the base of a vertical drainage stack where the wastewater starts to travel horizontally.

Can a wye be installed horizontally?

IPC TABLE 706.3 “fittings for change of direction” says wye is okay for horizontal to horizontal.
