Does kitchen sink need a trap?
Beneath a kitchen or bathroom sink drain is a pipe with a sharp bend in it. You must have a p-trap installed under your sink if you want your home to pass inspection in many places, where the building code requires them. Even if they are not required, you should understand the practical purpose for installing a p-trap.
Are sink traps universal?
So many people have asked about trap/drain sizing for fixtures we decided to give you at least a loose guide for each type of plumbing fixture. Please note, although these sizes are pretty universal they are still subject to local plumbing codes.
How far below the sink should the P-trap be?
When designing a house, it can be hard to determine how far below the drain a P-trap should be. The P-trap should be located no more than 24” below the drain.
Where is the trap on my kitchen sink?
Also known as a “P-trap,” a sink trap is a curved length of pipe located below the drain. If you follow the drain pipe from the bottom of the drain to the wall, this bend should be relatively in the middle, underneath the sink.
Does trap have to be directly below drain?
The “P” trap SHOULD be directly under the drain, but no more than a few inches off center of it, if conditions require it.
Can a kitchen sink have two traps?
It is perfectly fine to have (2) “P” traps, one on eash sink of a (2) sink setup. As long as the “P” traps are not Double Trapped ( more than one trap serving a fixture ) then it is fine as long as the weir is sized correctly.
Do I need a grease trap or interceptor?
A grease trap works well with a lower volume of flow; less than 50 gallons per minute. Large-scale establishments with a higher volume of flow; more than 50 gallons per minute, will need a grease interceptor, as they are better equipped to handle the extensive FOG that flows through the device.
How do I know what size P trap to get?
If you have 2.5 inches from the bottom of the tailpiece to shelf and 0.5 inches from the drain to shelf you can use CP-trap. First you have to cut 2.5-2.0 inches from the end of the tailpiece. The height of the p-trap is 4.5 inches 5-2.5=2.5 inches or 4.5-2.5=2.0 inches.
Does it matter which way the P-trap goes?
The outlet end of the trap pipe should be lower than the inlet when installed properly. The example shown has it backward, which creates a trap seal more than 4” and makes the drain more likely to clog—and that’s a long explanation for why a backwards trap is a bad thing.
Where do P traps go?
Plumbing codes require a P-trap be installed anywhere there is an open drain line that expels wastewater into a drain waste-vent system. The P-trap traps solids that can clog the drain or sewer line. The P-trap stops sewer gases from backing into your home through the drain line.
