When you are done remodeling your kitchen or bathroom, you realize that new plumbing is in order.If this isn't an issue you've run into before, you might find it more difficult than most other do-it-yourself projects.There are simple ways to make sure your pipes are well-ventilated.
A quick internet search for "plumbing vent diagram" will bring up multiple ways to tackle this issue, but how do you know which one will work for your home?What are the advantages and disadvantages of each system?Here is how to properly vent your pipes.
If you start from where you can see, it will be easier to see the pipes inside your wall.You have opened up the cabinets under the sink to see the P-shaped tube, right?The sewage/ventilation process starts with the P-trap.
The drain pipes connect to showers, sinks, tub, and other appliances in order to carry water away after you use it.The water moves into larger drain pipes as they connect and make their way to the stack.The same thing happens for toilets and soil pipes.
The stack pipe leads out through your roof and underground in the opposite direction of the main sewer lines.Water and waste head down the pipe.The fresh air in the stack helps keep the water flowing.
Without the stack, your home would smell and fill with sewer gasses.To help the stack do its job, ventilation pipes are often added to fixture so that gasses can freely move away from your home while using fresh air to move sewage freely.
It isn't something most homeowners like to think about, but it is a critical part of any household.It is important that you make sure the plumbing system works properly when you add a new fixture or fix your plumbing.
The vent is attached to the drain line through the roof.If a fixture rests close to the stack and the top floor of your home, it will serve as a vent.There is no water running through true vents.It is not always possible to find a solution that is close to the stack.
Attach the re-vent pipes to the drain line near your fixture as they run up and over the main vent.They can be attached to the drain line.When your sink is too far away from the main stack, these are excellent options.
If you have another fixture on the opposite side of the wall, you might want to use a common vent.Both drain lines can be tied together in a sanitary cross.The loop vent is a solution for many freestanding sink codes.It loops up an around before connecting to the drain pipe.The tub that sits close to a stack may not be allowed by your locality's code, so there is a wet vent.
Some codes allow for air admittance valves.These allow air to enter as waste drain, then rely on gravity to seal back up before gasses can make their way back into the room.Before buying any of these, make sure to check with your area's codes.
It is important to place your fixture a certain distance from the vent pipe.A few calculations are needed to figure out the critical distance.The size of your pipes, the type of fixture you are installing, and the number of fixtures that are wet vented in your home all play a part in determining that measurement.
You should consult a plumbing inspector after measuring the length of your pipes.They can show you how to vent your pipes in a way that complies with local code.
Vent pipes don't need to slope.As long as there are no obstacles, you can run them level.The main goal is to keep the vent piping dry.The re-vent is the only exception since it runs horizontally.It needs to be at least six inches above the flood level to keep from getting wet.The rim or overflow hole is where the sink is.
It is highly recommended that you plan out your drain lines before you install your vents.The rest of the drain system is larger than the kitchen and bathroom.The larger branch drain pipes lead into the 4-inch stack.
Since the main stack is vertical, it is rare for this pipe to burst.The larger the pipes, the more water can flow through them.This is a good time to have a professional check your main drain line.
We thought it would be helpful to include a plumbing vent diagram in order to better visualize what these piping systems look like.A typical bathroom has multiple plumbing vents.There is a wet vent that connects to the bathtub.
The stack behind the toilet is where the true vent is.The sink is placed further away.A re-vent was added to make sure sewer gasses could escape.
The next image shows various types of vent piping behind a sink, giving you an idea of what those might look like in your own project.Depending on the layout of your home, one of these will work best for you.
If your sink is too far away from the stack for a re-vent pipe, this image will show you what the loop vent looks like.It shows what the sanitary cross would look like if you had a sink on the other side of the wall.Both sinks share a common true vent to the stack.
It is easier to imagine what these pipes would look like behind your bathroom or kitchen walls from the side angle.The main vent and waste pipe are separated behind the sink.The revert is at least six inches above the overflow line and connected with a drainage T.
If your walls don't leave enough room for any of the above vents, the local code may allow you to opt for an Air Admittance Valve.When negative pressure is developed from draining, this one-way valve is designed to allow air into the plumbing.After allowing air in, it seals itself back up to keep odors and gasses out.If you tear into the wall and discover there is no room for a vent pipe, keep this method in mind.You should always check your local codes with a plumbing inspector to make sure you can use an AAV.
There is only one thing to it.Now that you know the ins and outs of a proper sewage pipe, you can tackle this part of your renovation project.Refer back to the diagrams to make sure you are setting up the vents correctly.
