P-traps are required on all plumbing fixtures to prevent sewer gases from entering your home. The trap must have a liquid seal between 2 and 4 inches deep. Additionally, the vertical distance from the fixture outlet to the trap weir cannot exceed 24 inches, and the trap cannot be larger than the drainpipe.
Each “P” trap shall have a water seal of not less than 2 inches and not more than 4 inches and shall be set true to its seal. (6) Size.
S-traps are banned by modern plumbing codes because their shape causes a self-siphoning effect. When a large volume of water drains, it creates a vacuum that pulls the water out of the trap. This destroys the water seal, allowing noxious and potentially dangerous sewer gases to freely enter the home.
Never put anything down your drains or toilets except the "three Ps" (pee, poop, and toilet paper). Other items act as magnets for debris and build up into severe blockages over time, which can require Emergency Plumber Services or result in thousands of dollars in property damage.
The "135-degree rule" in plumbing states that the total (aggregate) horizontal change in direction for a drainage pipe—specifically trap arms—cannot exceed 135 degrees between the P-trap and the vent. Exceeding 135 degrees (such as using three 45-degree bends or a 90 and two 45s) requires a cleanout because sharp turns hinder flow and cause clogs.
Plumbing code violations are typically safety, health, or structural hazards. The most common mistakes include improper drainpipe slopes, missing or unvented P-traps, illegal pipe material mixing, water heater installation errors, and inaccessible shut-off valves or clean-outs.
Yes, a kitchen sink and toilet can share a drain, but they must be connected properly to meet modern plumbing codes and prevent clogs, typically by linking to a larger, common drainpipe downstream. However, they cannot simply connect to each other; they require individual P-traps, proper venting, and appropriate pipe sizing to prevent wastewater backflow and sewer gas leaks.
Pouring vinegar down your drains in October is a proactive maintenance hack to clear seasonal sludge, prevent winter blockages, and deodorize plumbing before the colder months set in.
Plumbers strongly advise against using Drano and similar chemical cleaners because the caustic chemicals (like lye) generate immense heat that can melt PVC pipes, crack porcelain, and destroy older plumbing. Instead, professionals recommend using safe and effective methods to clear blockages.
Scrambled eggs can go down your garbage disposal, but only in small quantities. Because cooked eggs are soft, your disposal's impellers can easily process them. However, eggs are rich in proteins and fats, which can turn into a sticky, dense paste that coats your pipes or causes blockages if too much is put down at once.
Many older, traditional plumbers dislike PEX (cross-linked polyethylene) because its speed and ease of use lower the barrier to entry for DIYers, leading to concerns about unshielded materials, water flow restrictions, and chemical leaching. They also cite a lingering trust in the longevity and structural rigidity of copper.
Straight piping is not typically a felony, but it is illegal for public road use across all 50 states. In most cases, it is considered a traffic violation resulting in fines. However, tampering with or removing federally mandated emissions equipment like a catalytic converter can carry much steeper federal penalties.
Plumbers advise against chemical drain cleaners because the harsh, corrosive chemicals (like lye or sulfuric acid) generate extreme heat to break down clogs. This reaction can warp plastic pipes, destroy plumbing fixtures, and create a severe safety hazard for professionals if the drain needs to be manually uncloged later.
No, you cannot have two P-traps in series (one after another) on a single drain line. Known in plumbing as "double trapping," it creates a trapped air pocket between the traps. This blocks airflow and severely restricts drainage, often causing bubbling and intermittent backups.
Depending on whether you are referring to plumbing or wildlife, the term "trap" refers to two highly regulated categories.
Yes, Dawn dish soap can help clear minor, slow-moving drains. Because it is a powerful grease-cutter, it is highly effective at breaking up soap scum, fats, and oily blockages, but it won't clear solid obstructions like hair, food, or hard objects.
Many traditional Old Order Amish communities view store-bought toilet paper as an unnecessary indulgence or luxury. Instead, they rely on readily available, sustainable alternatives like crumpled-up old newspapers, mail-order catalogs, corn cobs, and cloth rags, though more progressive groups now commonly use conventional toilet paper.
People pour salt down the drain at night primarily for routine maintenance. The coarse texture acts as a gentle abrasive to scour away minor grease, soap scum, and grime, while the overnight window gives it time to absorb moisture and loosen buildup before being flushed away.
Yes, shower water goes into the sewer. It flows down the same main drain line as your toilets and sinks, eventually routing to a municipal wastewater treatment plant where it is cleaned before being safely returned to the environment.
The "135 rule" in plumbing is a standard code requirement that dictates how sharply a horizontal drain pipe can bend. It states that the total aggregate bend (change in direction) in a drainage line cannot exceed 135 degrees before an access point—known as a cleanout—must be installed.
PMRs for malignancies of the stomach, kidney, brain, and lymphopoietic system were also elevated, especially among plumbers. Chronic rheumatic heart disease, emphysema, liver cirrhosis, and all external causes of death were the major non-cancer causes with significantly elevated PMRs.
Whether you can find out who called code enforcement depends entirely on your local laws, as caller confidentiality rules vary by city and state.
Putting ice in your garbage disposal acts as a natural scrubbing mechanism. As the ice is ground up, the frozen chips knock away trapped food particles, grease, and foul-smelling gunk from the blades and the inside walls of the unit.
Compost or Trash
If you do not have a compost pile at your home, check your local municipal recycling website to see if composting services are offered in your community. If composting is not an option, it goes in the trash.
No, the chalaza is not the umbilical cord. It is a pair of twisted, rope-like strands of protein (thickened egg white/albumin) that anchor the yolk in the center of the egg, ensuring it stays suspended and safe from touching the shell.
