yes. The kitchen drains are normally 1 1/2 inch so you have enough drain to carry the sink addition.

ANS 2 YES there is a standard ABS coupling to do so

The vent for the drain is in the wall. Where the drain goes in, it T's with the water going down and the vent going through the roof. With a double sink, one side is the vent for the other. As long as the water isn't pulling against a vacuum, it will drain.

If the drain is used as a wet vent for another fixture 2". Otherwise 1.5".

Bath sink is not vented properly so it is using the kitchen sink as the vent.

By properly sizing the vent by fixture units and developed lengh and pitching it up from the fixture it serves

The gurgling in your kitchen sink drain trap is because your drain system from you upstairs toilet is not vented properly. As the flow drops down the vertical drain pipe from the upstairs it sucks the water out of your kitchen sink drain trap and causes it to gurgle. It could drain the kitchen sink trap and allow sewer gas to flow into your kitchen. The fix is to either install an Air Admittance Valve (AAV) in your kitchen sink drain plumbing or properly vent the upstairs toilet drain.

Make sure the drain line and the vent are cleared. Noises like that are usually caused by either restricted flow or a plugged drain vent.

Heck no as the sink is higher then the basement drain and water does NOT flow up hill BUT it does seek its own level BUT you can connect a sink drain to a basement drain if you properly trap and vent the line

This would not be a good idea because if you get any back draft which is likely when the vent isn't working then you have one smelly bathroom.

your vent on your shower or kitchen (if you have one) is not working and either the air from the water in the shower drain is carried down stream till it T's off to your kitchen sink then the air follows to your kitchen sink drain line backwards and to your kitchen sink trap and then bubbles through your trap because your water in your kitchen trap can not drain but the air has enough pressure to go through it OR your water from your shower is flowing past your kitchen drain T and making a siphon which causes air to go through your kitchen trap and makes the gurgling sound one way to fix the problem is to add a Vent line on your kitchen drain and your shower drain with in 42" on 1 1/2 or 60" on 2" on your trap arm if you want to follow the UPC code. Note to above Respondent: That little dot next to the question mark is a "period". Try throwing one in once in a while.

The most common kitchen drain problems are caused by dumping unsuitable foodstuff in the drain. I see many plugged drains with fish bones, rice, fatty substances, and similar . Needless to say, all waste food should go into a garbage bag, NOT down the drain. Vent issues are very seldom a problem, this would have been noticed as soon as the kitchen was used back when it was new

The vent is behind the overflow cap where you close the drain. --Without a vent, the water would drain very slow.

User Avatar

You PROBABLY have either a partially blocked drain line or possibly a missing or blocked drain vent. It's all behind the walls and if the drain vent is missing it is a direct reflection on the skill and/or integrity of the plumber. If the drain or vent is blocked, that is just a function of home use. A GOOD, plumber can help you figure out what is wrong. Sometimes the solution can be as simple as a stackless vent, but those devices are not allowed in some communities so check with local building code.

Drain, Waste and Vent System. It is all of the Drain and Waste piping and their associated vent piping

A tub drain vents through the overflow.

Kitchen sink drains are a fertile environment for certain forms of life, and these can cause the drain to run slow. When hot water is run down the drain, it kills some of the lifeforms, allowing the drain to run freely for a while. Try using a drain cleaner, or a drain snake, to clean out the drain. Never pour grease down a drain, as it cools and solidifies quickly in the pipes.

It will usually be vented through the main vent.

If the vent pipe is below the flood level of a fixture you just defeated the purpose of the vent entirely

User Avatar

There is a vent available for this. It is meant to cap 1 1/2 PVC. T the drain and put the vent as high as you can. It is spring loaded and the water will pull the vent open and close when the pressure equalizes. This is only for a single sink. If using a double sink, one side uses the other for the vent. You can use the add on with a double, you just don't have to.

User Avatar

Yes you have to have one

User Avatar

Vent piping is a pipe that runs outside and is connected to the drain line of your home. this helps the water in the drain to move to your septic/sewer.

The only way to properly clear a kitchen vent Or waste is by water jetting to remove the soap scum and grease deposits
