Backwater valves are installed in the main sanitary waste piping line from the building to the sanitary waste line on the property, hence they are called in-line backwater valves. They are valves that are installed in your sewer line for the purpose of closing off the pipe when water tries to back up through it; they permit sewage to pass through in only one direction.

A storm drain is a network of underground pipes designed to control flooding by transporting stormwater from urban areas to a body of water. A storm drain may also be known as a curb, gutter, channel, ditch, pipe, or culvert. Facility storm drainage is therefore a network of pipes inside the envelope of a building which may include underground piping designed to control flooding by delivering stormwater from the roof to the network of pipes outside the building. Facility storm drainage is therefore restricted to that which is installed within the envelope of the structure to drain storm water from the roof of the structure.

A sump pump is an automatic water pump powered by an electric motor which removes drainage, excluding raw sewage, from a sump or low point. There are two basic kinds of sump pumps: pedestal and submersible. Either will work well with proper maintenance. Pedestal sump pumps are powered by an electric motor which sits on top of a pedestal. The pump itself sits down in the sump, but the motor sits on top, out of the pit. A pedestal pump motor is not designed to get wet. The pump is turned on and off by a ball float. One advantage of this type of pump is that the on/off switch is visible, so the action of the ball float can be easily seen.

A water heater adds heat to water, raising its temperature. A commercial gas water heater consists of a gas fired burner to heat the water, and a separate hot water storage tank. In most residential water heaters, the heater is combined with the storage tank. A commercial gas water heater also differs from a residential water heater in capacity and durability or life expectancy, and in the fact that there can be multiple heaters and multiple tanks.

Residential plumbing fixtures differ from commercial plumbing fixtures in that they are not usually constructed to be as durable. All faucets, spouts, strainers, traps, waste piping, stoppers, stops, and escutcheon plates are considered trim and are included in Residential Faucets, Supplies, and Trim.

Each residential plumbing fixture has associated with it necessary items that are often not included with the fixture. Some of these extra parts are the faucets, supplies, and trim.
