The p-trap is a u-shaped pipe that is installed under the sink to prevent foul odors and gases from entering the home. The p-trap also traps debris that can clog the sink. Most sinks have a p-trap installed, but a double sink may have two p-traps.
If you have a double sink in your home, you may be wondering if you need two p traps. The answer is yes! Each sink needs its own p trap in order to function properly and keep your drains clear.
Having two p traps also helps to prevent cross contamination between the two sinks.
Double Basin Sinks and P-Traps

If you have a double sink, there are a few different ways that you can plumb the drains. The most common way is to have two p-traps, one for each sink. This is the easiest way to plumb the drains and it is the most effective way to keep sewer gas from coming up through the drains.
Can double sink share a trap?
Can double sink share a trap?
The simple answer is yes, but there are a few things to consider before doing so. First, check with your local building code to see if there are any restrictions on sharing traps.
Second, make sure both sinks are the same size and style – otherwise, one sink will always be draining slower than the other. Finally, it’s a good idea to have a plumber install an air gap between the two traps to prevent any sewer gases from coming back up into your home.
Does a double sink need two drains?
Most double sinks come with two drains, but this isn’t always a requirement. If you’re considering a double sink for your bathroom or kitchen, you may be wondering if you need two drains. The answer depends on a few factors, including the size of the sink and the type of plumbing you have in your home.
If you have a small double sink, you may be able to get away with only one drain. This is because the two sides of the sink are usually not used at the same time. For example, if one side is used for washing dishes and the other side is used for rinsing, you may not need two drains.
However, if both sides of the sink are used for washing dishes simultaneously, you will need two drains to prevent water from backing up. The type of plumbing you have in your home is also a factor to consider. If you have a standard drain system, you will need two drains for a double sink.
If you have a sewerage ejector system, you may only need one drain. This is because the sewerage ejector system pumps waste water out of the home, so there is no need for a second drain. In most cases, a double sink will come with two drains.
However, there are some exceptions. If you’re considering a double sink for your home, be sure to consult with a plumbing professional to determine if you need two drains.
Can a double sink share the same drain?
A double sink, also called a dual sink, has two separate basins that are usually the same size. They can be used for different purposes, such as one for washing dishes and the other for hand-washing clothes. Most double sinks have one drain, but it is possible to have two drains.
If you have two drains, they will need to be connected to different pipes.
Does each sink need a trap?
The quick answer is yes – each sink needs a trap. But let’s explore this a little further.
A trap is a curved section of pipe that is installed under a sink (or other drainage fixture) to capture water and prevent sewer gases from entering the home.
The trap forms a water seal that is designed to keep sewer gases out of the home while also allowing wastewater to flow freely out of the sink. There are several reasons why it is important to have a trap installed under each sink. First, as we mentioned, it helps to prevent sewer gases from coming into the home.
This is important for both indoor air quality and for safety reasons. Second, the trap helps to keep small objects from going down the drain and becoming lost in the sewer system. This is especially important for homes with small children who might accidentally drop small toys or other objects down the sink.
Third, the trap provides a water seal that helps to prevent sewer gases from entering the home. This is important for both indoor air quality and for safety reasons. Fourth, the trap helps to keep small animals from entering the home through the drains.
This is especially important for homes in areas where there are rodents or other small animals that might try to enter the home through the drains. Overall, it is important to have a trap installed under each sink in order to prevent sewer gases from entering the home, to keep small objects from going down the drain, and to keep small animals from entering the home through the drains.
No, a double sink does not need two P traps. A P trap is a U-shaped pipe that helps keep sewer gas and odors from coming back up through the drain. It also helps to prevent clogs by catching hair and other debris that can build up over time.
