A bell trap uses a basin with a bell-shaped component that fits over the drain pipe. The components are designed to keep gases from passing around the trap. Today, they are commonly used to trap gas leaks in residential and commercial buildings. Bell traps can be installed in a variety of locations, such as in basements, crawlspaces, garages, and attics.

Why are Bell traps prohibited?
Bell traps are not allowed in most US building codes. Simply put, they’re not a great idea and can get you into trouble in many areas. If you’re working with dangerous chemicals, the still water in the bell trap drain could cause mold and hazardous material build-up.
Bell traps can also be very expensive to install and maintain. If you don’t want to spend that kind of money on a new trap, you can always use an old one that’s been sitting around for a long time.
Are Bell traps prohibited?
The following types of traps are prohibited: Bell traps. A trap designed to catch the urine or feces of a person entering or exiting a bathroom.
The trap must be designed so that it does not interfere with the person’s ability to enter or exit the bathroom, and it must not be used in a manner that could cause the trap to be triggered by the presence of urine, feces or urine-like substances in the toilet bowl or in any other part of the restroom.
This includes, but is not limited to, the use of an electronic or mechanical device that can be activated by a sound, light or vibration, or a combination of these factors. For example, a toilet seat or toilet paper dispenser may be considered a trap if it is used to dispense a liquid or solid substance, such as toilet water, into a receptacle that is designed for the dispensing of liquid, solid or gaseous substances.
In addition, any trap that has a spring-loaded mechanism that allows the user to push a button to activate the mechanism is prohibited.
Do floor drains need Cleanouts?
Cleanouts are required for horizontal drainage piping. Every 100 feet, a cleanout is required for long runs of piping. The measurement is taken from the highest end of the horizontal drainage piping to the point of connection with the water main. Vertical drainage piping shall be measured in accordance with Section 709.2.
The vertical drainage pipe shall have a minimum diameter of 1 inch (25 mm) and a maximum length of 4 feet (1219 mm). The minimum vertical diameter shall not be less than the minimum horizontal diameter and the maximum vertical length.
Why are Crown vents prohibited?
P-trap, with a vent separated from the trap, evolved to become a better design, and crown vents were banned by the building codes in the 1970s. In the 1980s and 1990s, a new generation of venting systems was developed, but they were not as effective as the old ones.
In the early 2000s a team of researchers at the University of California, San Diego, developed a system that was more effective than any of the previous designs. They called it a “pump-and-drain” system, because it uses a pump and a drain to move water from one part of a building to another, rather than using a single pipe to deliver water to the entire building.
Pumping water through a pipe is more efficient than pumping it through the roof, which is why it’s called a roof-mounted system. It’s also more energy-efficient, since it doesn’t require as much energy to pump the water than it does to run the pump.
What is considered an S-trap?
S-traps are a type of plumbing trap that blocks sewer gases in sinks and other plumbing fixtures. S-shaped pipe configuration traps wastewater before it goes to the sewer line, creating a water seal that prevents gases from flowing into the house.
The traps are typically installed in the basement or crawl space of a home, but can also be installed on the side of the home or in a garage. They can be used to trap odors, bacteria, and odorous liquids, such as urine, feces, or urine-soaked bedding.
Why is my S-trap leaking?
Plastic-pipe traps are more likely to leak when the pipes or washers become misaligned, so check for alignment. Check the pipes to make sure they are free of rust. If your pipe is cracked or corroded, take it with you to the hardware store to get a new one.
If you can’t find a plastic pipe trap in your area, check with your local fire department to see if they have any. They may be able to help you find the right one for you.
