How many bends can you have in a drain pipe?

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 toilet shower and sink share a vent?

As a general rule, you will just be able to vent 2 fixtures on a toilet wet vent. … 1) Toilet and Sink: The toilet is vented through the sink drain. The toilet drain should be 3″, the sink drain is 1.5″, the shared sink drain/toilet vent area should be 2″, and the vent going up should be 1.5″.

Do I need a vent pipe on a toilet?

Vent pipes supply fresh air to each plumbing fixture in the house, which helps the system move water through the drainage pipes each time a toilet is flushed or a sink is drained. Plumbing air vents also prevent sewer gases from entering the home and allow wastewater gas and odor to escape.

How far can a plumbing vent run horizontal?

How does a sanitary tee work?

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. Like other types of T fittings, it connects two pipes for a main run and one at 90 degrees for a branch run.

Can you put an elbow in a vent pipe?

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.

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.

What is the difference between a sanitary tee and a regular tee?

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?
