If you need to replace your old exhaust fan and want to use a cheater vent, here's how to do it. The process is fairly easy if you know the basic steps to follow. After you have determined the exact spot where you want the cheater vent, you should run the pipe to the existing vent. If possible, route it toward the back of the sink, so that it is easily accessible and easy to service if necessary.
The waste arm assembly should point up. You can use a torpedo level to plumb the AAV. Make sure it is no more than 15 degrees off the vertical. Once the AAV is installed, run a hose to test its drain function and check for leaks at the pipe joints. If the drain still does not drain properly, you can install a new vent.
Necessary to mark the joints
Once the drain trap is installed, attach the sanitary tee to the waste line. The 1.25" port of the sanitary tee should be pointed upward. Make sure that the sanitary tee is at least 6 inches above the roofline. Once you've connected the sanitary tee, insert the drain arm into the new sanitary tee. Don't forget to mark the joints before solvent-gluing.
Need a vent pipe
If you need to vent your nivito under a window, you need a vent pipe. These vent pipes are usually made from PVC or PEX plastic, which may not be ideal for plumbing applications but work fine for air ventilation. Make sure the vent pipe is not smaller than 1.5 inches in diameter. You'll also need a flexible vent pipe that's long enough to allow the exhaust to escape from your kitchen.
Install an AAV
AAVs can be installed in a kitchen sink or other fixtures, depending on the model. Installation depends on local codes and on the model you choose. It's important that you install the AAV in an area where the water flow doesn't create a negative pressure. Otherwise, your vent may be slowing down your sink's drain. It's important to note that these types of vents can also be found in older bathrooms and other spaces, so if you want to avoid leaks, it's better to install an AAV than a traditional one.
Choose a flushing vent
If you're having gurgling problems while using the sink, you can choose a flushing vent. To fix a gurgling problem, you can flush the pipes by running hot water through the sink for 15 minutes. You'll need to follow these instructions to install a flushing vent. The best way to flush the pipes is to run hot water through the sink for 15 minutes and then flush the drain.
