Glossary of Plumbing Terms


When we conduct high-risk component inspections on your premises, you’ll hear us use the terms “New,” “OK”, or “Old” to rank your products. Here’s what we mean by those terms:iStock_000007185491XSmall(new)

NEW – Current conditions require no repairs or replacements. Check occasionally for signs of wear. Maintain as recommended by your plumber’s or manufacturer’s instructions.

OK - Check regularly for signs of wear. It is recommended that fixtures, valves, & supply lines be iStock_000002782182XSmall(ok)replaced when their lifespan nears its end. Do not wait for something to wear out completely before replacing it.

OLD - Current item is nearing or has reached the end of its recommended lifespan. Parts may be corroded, damaged, or worn beyond repair. We recommend replacing or repairing immediately to iStock_000001731024XSmall(grunge sink)avoid costly water damage or further corrosion. 



Camera inspectionPipe-inspection cameras can go in and tell the condition of sewer pipes and lines.

Cesspool - Cesspools are a giant hole or series of holes in the ground, sometimes as much as 30 feet deep. The solids drop to the bottom of the hole, while the liquids leach out the earthen side walls. Over time, the porous walls become blocked with sediment, and it becomes necessary to pump the excess waste and water. Typically cesspools become more problematic as they age or as the ground becomes saturated with excess water.

Gas pipelineGas piping - Piping designed to carry liquid propane to appliances and fixtures such as barbecue grills, tiki torches, clothes dryers, water heaters, and cooktops.

Grease trapA grease trap collects excess grease and build-up from kitchens and heavy grease-producing fixtures such as kitchen floor drains, three-compartment wash sinks, and commercial dishwashers.

Rinnai on-demand water heaters - Energy-efficient tankless water heaters that heat the water as you need it.

Septic System - Septic systems are equipped with a leach field and underground series of chambers that allow the liquids in the system to flow from the tank and dissipate in the ground. The solids are trapped in the septic tank and slowly compost and break down. However, over time, these solids will build up. It is recommended that the septic tank be pumped every 5-7 years.

Sewer jetting - High-pressure water cleaning for the interior of sewer and drain lines.

Solar hot water systems - Hot water systems that utilize the sun’s energy to heat and store water.

Solar repair - Troubleshooting and service for sun-powered hot water systems.iStock_000004446971XSmall(stop valve)

Stop valve - Also called “angle stop”, these are the valves located on the water supply for each fixture that allow for quick and easy isolation for the fixture. Make sure you locate these valves and check to see they are functioning properly. It may become necessary to turn the water off to a fixture in the event of an emergency.

Supply line - Flexible tubing carrying water from the stop valve to the fixture.

Water catchment system - A holding system designed to catch and recycle rain water.

Water disbursement system - Water piping that carries water throughout a structure to each individual fixture.

Water heater - A device or appliance used to heat or store hot water.
