P-traps are generally considered by most to be more effective and consistent in maintaining water trap compared to S-traps. Their design makes them less vulnerable to drying out and losing seal: a properly installed P-trap will never lose its water seal..

How do you know what size P trap?
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.
Are P traps necessary?
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.
Are kitchen sink P traps universal?
When replacing a pP-trap, you should use the same type of trap you remove. Traps are made from polypropylene (white or black), ABS (black), PVC (white) or brass (either chrome-plated or natural colored). Traps come in 1-1/4 inch (standard bathroom sink) or 1-1/2 inch (standard kitchen sink) inside diameter sizes.
Does length of P-trap matter?
Minimum Distance
The trap arm that connects horizontally from the vent pipe to the p-trap must have a slope of 1/4 inch per foot sloping up toward the drain. If the sink has a pop-up drain, the tailpipe will need to be long enough to house the drain mechanism.
Why does my P-trap leak?
When a P-trap leak occurs, it’s usually because the nuts aren’t tight enough, the pipes are misaligned or a P-trap washer isn’t seated correctly.
Does P-trap have to be below drain?
It is not ideal to have the p-trap below the the exit drain because water gravity has to force the water out instead of it flowing downwards naturally. They both work and have seen it many times. But essentially anything below already creates its own p-trap- so using another is redundant.
How far can you run a drain without a vent?
If you have 1- 1/4-inch pipe, the horizontal distance of the vent ought to not be more than 30 inches. For a 1- 1/2-inc pipe the vent must be 42 inches away at the most while a 2-inch pipeline must have an optimum distance of 5 feet.
What height should a sink p trap be? The trap is usually attached to the end of the tailpiece, and tailpieces are typically between 6 – 8 inches long (though I’ve seen up to 12). So the “standard” height of a trap would be, 6 – 8″ below the fixture.
Why are S traps not allowed?
The “S” trap is prohibited under the Uniform Plumbing Code throughout the United States. This is because the “S” trap will siphon or suck water out from the trap which will end up releasing methane (sewer) gases into the home. So, it is a code violation and if you are doing remodeling, you will have to replace it.
What is the name of the fitting that connects the P-trap to the drain?
Tailpiece: Often referred to as the drain tailpiece, this is the section of piping that connects to the drain fitting. It carries water away from the sink.
Does every P-trap need a vent?
P-traps need vents
1 – They give the sewer gases a place to vent, so they do not build pressure inside your sewer lines.
What can I use instead of an S-trap?
P-traps replaced the use of s-traps, particularly under sinks, to eliminate the siphoning problem. A p-trap has two main features that stop siphoning. The first is a vented pipe. A p-trap is vented typically inside a wall and through the roof to the outside air.

Why are S-traps still sold?
This is critical because, without a vent, the S-trap eventually fails. You can still buy S-traps in stores, because they have some legitimate uses, but they aren’t suitable for beneath your sink. If you currently have an S-trap, it may have been installed before the building codes outlawed them.
What is gully trap?
A gully trap is a basin in the ground which receives piped wastewater from inside your home before it is emptied into the wastewater network. The basin has a water seal to prevent foul odours of the sewer reaching the surface, and a vent pipe that allows fresh air in.
