The pipe used to carry rainwater off a roof and down to the ground or a drainage system is primarily called a downspout, downpipe, or drainpipe.
In rainwater systems generally, white stormwater piping (i.e. mostly referred to as SD piping) is used for both the incoming and outgoing water flows for the system.
A rainwater pipe is most commonly called a downspout in the United States and Canada. In the UK, Australia, and other Commonwealth countries, it is typically referred to as a downpipe.
You should avoid plumbing pipes that pose severe health risks (like lead) or are prone to sudden, catastrophic failures and leaks. The top three pipes you never want in your house are Lead, Polybutylene, and Galvanized Steel.
Yes, you can boil rainwater to kill biological pathogens like bacteria and parasites, making it microbiologically safer to drink. However, boiling does not remove chemical contaminants, heavy metals, or microplastics from the air and collection surfaces.
Collecting rainwater is not illegal in any U.S. state, but it is highly regulated in a few areas. Restrictions exist to protect prior appropriation water rights (where downstream users legally own the water), maintain natural watershed ecosystems, and prevent unsafe drinking conditions.
While water quality varies by city rather than just by state, Pennsylvania and Texas frequently rank as having the worst overall tap water. Pennsylvania struggles with a high volume of EPA violations and legacy pollutants, while Texas serves millions of residents with water that tests high for contaminants like arsenic and byproducts.
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.
Keep your thermostat set to a minimum of 55°F (13°C) to keep your pipes from freezing. If you are leaving the house for an extended period, maintain this temperature to ensure heat reaches the walls where pipes are located.
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.
The thing at the end of a downspout is called a splash block (if it rests on the ground) or a downspout elbow/shoe (the curved metal or plastic piece that directs water outward).
Never pour grease, oils, coffee grounds, starchy foods (like pasta, rice, or flour), eggshells, or harsh chemicals (like paint or bleach) down your sink. These items either solidify, expand, or combine with water to create stubborn blockages, damage plumbing, or cause environmental pollution.
No, you should never remove your downspouts in the winter. Even during cold weather, sunny days can cause snow on your roof to melt. If downspouts are detached, that meltwater will pool, refreeze, and cause ice dams, roof leaks, or severe water damage to your home’s foundation.
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.
A downspout is a pipe that carries rainwater from a roof gutter down to a drain or to the ground.
Unprotected standard PVC pipe will typically last 5 to 15 years in direct sunlight before becoming brittle. While UV rays do not compromise the pipe's pressure capacity or rigidity, they strip away its impact resistance, making the plastic susceptible to cracking under pressure or physical stress.
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.
A 90-degree pipe fitting is commonly called an elbow (or "ell").
Most plumbing code violations stem from improper DIY fixes, unpermitted renovations, and outdated materials. The most frequent infractions—which can cause leaks, contamination, or failed inspections—involve improper drainpipe slope, inadequate venting, missing or faulty backflow prevention, and improper water heater installations.
You only need to drip one or two faucets. Prioritize the ones farthest from where the main water line enters your home, or those located on exterior walls. Open the cabinet doors underneath the sinks so warm room air can circulate to the pipes.
At a sustained outside temperature of exactly 32∘F32 raised to the composed with power F32∘F, it takes at least 12 hours for unprotected pipes to freeze. Because water needs time to cool and solidify, actual freezing is much faster at 20∘F20 raised to the composed with power F20∘F or lower, which can take just 6 to 8 hours.
Whether 74°F is too high for winter depends entirely on your heating costs and personal comfort. However, most experts consider it warmer than necessary for energy efficiency.
Albert Einstein famously said, "If I would be a young man again and had to decide how to make a living, I would not try to become a scientist or scholar or teacher. I would rather choose to be a plumber."
Roofing is historically the deadliest construction job. According to labor and safety agencies, roofers face one of the highest fatal injury rates in the industry, generally exceeding 47 deaths per 100,000 workers, largely due to the constant threat of falls.
