No, P-traps are not illegal. In fact, they are the standard, code-approved water trap required under sinks by modern plumbing codes (like the UPC and IPC). They create a necessary water barrier that prevents dangerous sewer gases from entering your home.
S traps are generally discouraged or prohibited because they can siphon water out, breaking the seal. Bell and drum traps are less common and may not meet current plumbing codes.
Code-Compliant: Most building codes now require P-traps. Reliable Water Seal: Less prone to siphoning compared to S-traps. Easy to Clean: Most modern P-traps are designed with access points for cleaning out debris. Flexible Design: Can be easily connected to wall drains in modern homes.
A P-trap is the better and far safer option. It is the modern plumbing standard for sinks and basins because it prevents dangerous sewer gases from entering your home. S-traps, on the other hand, are banned in most modern building codes due to their tendency to siphon water out of the pipe.
S-traps are banned in modern plumbing codes because their unique shape acts like a siphon. As water drains, it can create suction that empties the trap. Without this barrier of water, noxious and potentially explosive sewer gases are allowed to travel directly into your home.
The Protocol prohibits the use of land mines, remotely delivered mines, or booby traps to kill civilians or to cause superfluous injury or unnecessary suffering to soldiers.
The definitive answer is No. Straight piping is illegal for public road use in all 50 U.S. states. Regardless of local inspection rules, the Federal Clean Air Act prohibits removing catalytic converters or mufflers from any street-legal vehicle.
In plumbing, the "135-degree rule" is a code standard that dictates how much a horizontal drain pipe can bend or change direction. It limits the total cumulative angle of pipe fittings before a system requires an access point (cleanout) or must be vented, ensuring proper flow and preventing chronic clogs.
Inconsistent Performance: S-traps are not vented properly, leading to inconsistent performance. This can result in slow drainage and frequent clogs, making your plumbing system less reliable and more prone to issues.
Technically, no — toilets do not have P-traps in the traditional pipe sense. Instead, they're built with an internal toilet trapway. This is a curved passage inside the toilet that traps water to block sewer gases.
How do you get a snake past the P-trap? For minor clogs, feed the snake through the drain and guide it around the curve. If resistance is too high, remove the P-trap and insert the snake directly into the wall drain.
A straightforward yet effective approach to addressing a clogged drain pipe involves simply using hot water mixed with dish soap. This method, ideal for tackling minor blockages, leverages the degreasing power of dish soap combined with the force of hot water to dislodge and dissolve clog-causing residue.
Drum traps are prohibited in modern plumbing codes (like the Uniform Plumbing Code and International Plumbing Code) for new construction because they are prone to severe clogging. Unlike self-scouring P-traps, drum traps allow hair, soap, and debris to collect in a way that is difficult to clear with a standard plumbing snake.
Yes, you can absolutely get in trouble for buying a solvent trap. While buying an un-modified trap for legitimate gun cleaning is legal, the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) considers many of these devices to be illegal, unregistered silencers.

Pouring salt down your drain at night is a popular DIY plumbing trick used for routine maintenance. The goal is to take advantage of the salt's coarse texture and natural moisture-absorbing properties.
Yes, it is normal and beneficial to have water sitting in your P-Trap as it serves as an essential barrier against sewer gases entering your home.
It's best to instead opt for a Drano alternative as a safer and more plumbing-friendly way to unclog your drains. Some of the best Drano alternatives include using a plunger or pipe snake, soap or salt mixed with boiling water, or baking soda and white vinegar.
Yes, a toilet and a sink can share a vent. In modern plumbing, this is most commonly done using a wet vent, where the sink’s drainpipe also acts as the vent for the toilet.
a waste pipe must be layed so it has a fall of 1 in 4 (mcguires rule).
Street 90-Degree Elbow
Street 90-degree elbows have one end designed to fit directly into a fitting or valve without a connecting pipe. They can be used when a pipe needs to be connected to a valve or fitting at an angle. They are also commonly used when changing the flow direction in underground piping systems.
Yes, gutting your catalytic converters will almost certainly throw a check engine light (CEL) and trigger fault codes.
