When your plumber starts throwing around jargon like “manifold” or “flapper,” it can feel like they’re speaking a foreign language. Understanding the lingo can make plumbing issues less overwhelming and help you feel more confident about maintaining your home. Let’s break down some common plumbing terms and why they matter.
1. Shut-Off Valve
Also known as a water- or angle-stop, this is a homeowner’s best friend when dealing with leaks or emergencies. Found near sinks, toilets, and appliances like your washing machine, shut-off valves allow you to stop water flow to a specific fixture without affecting the rest of your home.
2. PSI (Pounds per Square Inch)
PSI is a unit of measurement for the water or gas pressure in your plumbing systems. Normal water pressure typically falls between 45 and 70 PSI. Low water pressure can mean a clog, leak or mineral buildup, while high pressure might damage your water pipes. Gas pressure is regulated by the gas meter outside, and is usually around 3.5 PSI. Low gas pressure will starve gas burning appliances, such as your furnace, stove, water heater, or dryer, causing them to run poorly. This is usually caused by a faulty gas meter, which the gas company replaces at no cost, or leaking gas lines.
3. Manifold
Think of a manifold as the heart of your home’s plumbing system. This central hub distributes hot and cold water to different fixtures, much like an electrical panel directs power. Manifolds help maintain consistent water pressure even when multiple fixtures are in use. Modern homes often have one central manifold with valves that can shut off flow to particular areas of the house. Older homes usually have multiple manifolds throughout the house.
4. Coupling
A coupling is a simple connector that joins two pipes. They can be made of metal or plastic and are essential for repairs or extending plumbing lines. In a city like San Antonio, where older homes often require retrofitting, couplings play a big role in keeping systems up to date.
5. Water Main
The water main is the primary underground pipe that delivers water from the city water system or treatment plant to your property. Before reaching your home, the water passes through a water meter, which measures usage, and continues into smaller pipes known as water service lines, which distribute water throughout your home. If there’s a leak or issue with any of these, it’s critical to address it immediately since it can lead to high water bills or even foundational damage. The city is responsible for the water main leading to your water meter and any water meter damage, assuming you or your plumber were not the cause of said damage. Only city representatives are allowed to operate and shut off the water at the meter, so having a shut off hand valve somewhere after the meter is very helpful for homeowners to shut off their water in the case of an emergency.
6. Toilet Flapper
This small but mighty component is found inside your toilet tank. It controls the water flow into the bowl during flushing and keeps the water sealed in your tank otherwise. If your toilet is running non-stop, a faulty flapper is likely the culprit.
7. P-Trap
The P-trap is the curved section of pipe you’ll often find under sinks. It holds water to block sewer gases from entering your home and helps prevent debris from clogging your pipes. Though a P-trap is considered the most common type, there are also S-traps, U-traps, and J-traps. Each has a specific purpose, named for the letter resembling its shape, but they’re not interchangeable. Using the wrong one can lead to drainage or venting issues.
Look Out For Confusing Lingo
Some plumbing companies use fancy language in place of common plumbing terminology as a sneaky sales tactic. For example, the term “High-Torque Obstruction Removal System” might sound like an advanced piece of technology, but it’s just a complicated way to describe a drain snake, a go-to tool for clearing clogs. If you ever come across confusing jargon on an invoice or in a conversation with your plumber, don’t hesitate to ask about it. You have a right to know what you’re paying for and if the plumber isn’t willing to clarify, it might be worth getting a second opinion.
