There’s a lot of language in plumbing, and not just the kind people use when the plumbing doesn’t work. We’re not talking about complicated trade jargon. (We’ll let the electricians keep most of that.) We’re talking about the many everyday words people use for common plumbing fixtures. The reason is pretty simple. The more important something is, the more words we seem to have for it. Many plumbing fixtures do similar jobs, but the names we use for them can vary depending on where we grew up or what we learned to call them. The more important a piece of plumbing is to your daily routine, the more likely it is to have several different names.
There’s one obvious example. Of all the plumbing fixtures in your home, it probably has the most names of any. It’s the one you’ve spent the most time waiting to use. It’s also the one that causes the most stress when it doesn’t work. Most plumbing professionals call that fixture a water closet. A thesaurus gives a long list of other names people use. It’s important enough that even before we gave the hint, you likely knew exactly which plumbing fixture we were talking about. Whether you call it a toilet, commode, restroom fixture or something else, you want to make sure that one is always working properly.
That was just one example, and maybe an extreme one. What about where all the water you need comes from? Faucet? Tap? Spigot? Spout? Bibcock? We all like turning a handle and having water flow right when we need it. We like it so much that we’ve come up with several names for it, depending on where it is. That fixture on your kitchen sink or bathroom sink might be called a faucet or a tap. The one outside your home may be called a hose bibb, sillcock, or outdoor spigot. The fixture on your laundry sink or utility sink might be called something slightly different again. No matter what you call it, it doesn’t matter nearly as much as who you call to fix or replace it. We know what you mean, even if the words change.
Sinks themselves are another good example. You may have a kitchen sink, bathroom sink, bar sink, laundry sink, or utility sink. Some people call them basins or washbasins. Showers and bathtubs bring their own set of names, too. You might hear tub, bath, shower stall, shower pan, or even combo unit. Add in fixtures like handheld showerheads, rain heads, and body sprayers, and the list grows even longer. Garbage disposals, sometimes called disposers or grinders, also fall into that category of everyday plumbing devices with more than one common name.
While lots of different words for one fixture often show how important it is, sometimes the reverse is true. Sometimes a plumbing fixture is so necessary and so common that one term is enough for everyone to understand right away. Water heaters may be the best example. Every home needs one, and there really isn’t much variation in the name, although you do occasionally hear “hot water heater.” Whether it’s called a water heater or a hot water heater isn’t as important as whether it heats water and does it reliably. The same goes for tank-style water heaters, expansion tanks and recirculation pumps that help deliver hot water faster throughout the house. No matter the wording, you rely on them every day.
Sometimes all the different words for a plumbing fixture come from people simply learning different names while growing up. Other times, the variety comes from advertising and product marketing. The tankless water heater is a perfect example. You might hear it called a tankless unit, flash water heater, instant hot system, on-demand heater or continuous flow water heater. Each name sounds a little different, but they all point to the same basic idea — hot water when you need it.
There are plenty of other plumbing fixtures and devices that show up in everyday conversations. Toilets connect to fill valves and flush valves. Sinks rely on drains, traps, and supply lines. Dishwashers, ice makers and washing machines all connect to your plumbing system and have their own valves and hoses. You might hear terms like floor drain, sump pump, ejector pump, backflow preventer, pressure regulator or shut-off valve. Outdoor irrigation systems, sprinkler heads and hose connections add even more names to the list. The point is, plumbing includes a wide range of fixtures and devices, and many of them have more than one name.
Some plumbing items have lots of terms because they are so important. Others have multiple names because manufacturers and advertisers want their products to stand out. Then there are specialized terms your plumber uses every day, words learned through years of training and hands-on work. You may hear your plumber talk about rough-ins, stub-outs, vent stacks, or supply manifolds. Those words describe specific tasks or parts of the system that keep everything running smoothly.
Don’t worry too much about getting the words exactly right. It’s our job to understand what you mean, even if you don’t use the same terms we do. It’s on us to know how to fix whatever is wrong in your plumbing system. It’s also on us to ask the right questions so there’s no confusion about what needs to be repaired or replaced. Leave the vocabulary to the plumber you trust. Understanding what you mean, making sure your plumbing works the way it should, is just as important as doing the repair itself.
