Plumbing glossary

Confused about the jargon? Don't know a float valve from a flapper? Here's an Angie's List glossary to plumbing-related terminology.

Hiring a plumber

When hiring a plumber -- especially for an expensive project for which you have time to plan -- make sure the plumber you hire is fully qualified and licensed in your state. A plumber may be an apprentice in training, a journeyman or a highly qualified master plumber depending on the level of training and experience.

Toilets

A product of thousands of years of human thought, the modern toilet is ingeniously shaped to flush away its contents whenever sufficient water is dumped into the bowl. The mechanical parts inside the tank merely supply that water -- but these are the parts you need to fix.

Sump pumps

A submersible sump pump detects increases in ground water levels and kicks on when needed.
A sump pump is like a sturdy, hardworking little robot that stands sentry in your basement, alert and waiting to detect any rise in groundwater levels that might cause a flood were it not for its diligence. When its services are needed, it goes to work pumping out the encroaching water, working tirelessly as long as necessary until the threat passes. Then it quietly stands down, expecting no thanks, and puts itself back on guard awaiting the next call to duty.

Septic Tank Installation

Septic systems

Cleaning a septic system needs to be done every couple of years.
Septic systems are commonly used in rural areas and sometimes in areas not served by a municipal sewage system. Septic systems absorb household sewage and distribute the liquid waste into a designated leach field where natural processes can reclaim it. However, solid wastes and grease must be pumped out of the septic system periodically.

Water Heater Installer

Water heaters

Installing a water heater is best left to a professional while homeowners can perform key maintenance.
Standard storage tank water heaters typically need to be replaced after about a decade, but they can last years longer with some homeowner maintenance. When the time comes to buy a new one, there are more options for consumers to consider.

Does a leaking water heater violate code?

Anytime a contractor tells you that you have a code violation, seek the opinion of at least two more reputable professionals in your area to help make sure what you’re being told is legitimate. When in doubt, contact your local code enforcement agency. (Photo courtesy of Angie's List member Michael K.)

Dear Angie: My water heater is leaking. The plumber I hired said it would cost $150 for a water heater code violation. Do you know what he is talking about? Is there such a thing? – G.C., Columbia, S.C.

Temperature relief valves critical to water heater safety

A T&P relief valve is a two-in-one safety device, which, as its name implies, responds to both excessive temperature and to excessive pressure in a water heater. (Photo courtesy of Angie's List member Robert B.)

Water heaters have many critical components, but none are more critical than the temperature relief valve. Learn how to make sure that your both T&P valve and thermal expansion tank are both working properly

How much should water heater installation cost?

The cost for a professional water heater depends on more than just the unit itself - meeting current plumbing codes, and ensuring safety and proper installation are important factors, too. (Photo courtesy of Angie's List member Michael K.)

Water Softener Maintenance

Water softeners

Even if your tap water comes from a reservoir, chances are it previously passed through underground caverns where it absorbed mineral deposits. Water with a high concentration of minerals is referred to as "hard" water. It's safe to drink but can harm your plumbing and appliances.

Do water softeners need regular maintenance?

The advantage of water softeners is they can extend the life of your water-using appliances, your plumbing and even your clothes. (Photo courtesy of Angie's List member Kevin F. of San Antonio.)

Dear Angie: I have well water for my residential water and use a water softener for it. I have not had the water softener system serviced for the past two-and-a-half years. How often should I have it serviced? What should an inspection/service include and how much will it cost? What can happen if I don’t have it serviced? – S.P., Fair Lawn, N.J.

Drain Pipe

Main sewer drains

The main sewer line is the homeowner's responsibility up to the edge of the property.
A home's main sewer drain carries all household sewage to municipal sewer lines or to an on-site septic system. Older drains can become invaded by tree roots, causing blockage that can lead to sewage backing up into the house. Replacing a drain can be expensive, though newer techniques can lessen the amount of digging required.

Pipe lining and bursting replacement techniques offer alternatives to traditional sewer line excavation.
