Healthcare Plumbing Fixtures
A plaster interceptor is a type of solids interceptor that is specifically designed to separate plaster from waste water (Z1180, Z1181).
A top spud fixture refers to a flush valve connection that is on top of the toilet generally located behind the seat. A back spud fixture has a connection for the flush valve located on the back of the toilet. In most cases a back spud fixture will use a concealed flush valve.
A carrier is a steel fixture that goes behind the wall to hold “wall hung” fixtures off of the wall….i.e. toilet, sink, urinal and for floor mounted back outlet bowls to secure the drain assembly to the fixture. It is required any time a wall hung fixture is specified.
The siphon jet bowl is attached to the carrier with four mounting studs arranged in a rectangular pattern whereas the blowout bowl is mounted on three studs arranged in a triangular pattern, point down. Additionally in a siphon jet bowl, the jet is located in the sump. The jet in a blow out bowl is located in the trap way. Siphon jet bowls can flush at 1.28 gpf whereas blow out bowls are typically 1.6 gpf and higher water usage.
Handicapped/elderly height (also known as ADA height) has a rim height of between 17 inches and 19 inches measured to the top of the toilet seat for closets and 17 inches for urinals. Standard height is typically 15 inches to the rim height.
Both terms are used interchangeably to describe the flushing mechanism for the fixture.
Both types of flush valve are sensor-operated. Battery type flush sensor flush valves are hands-free activated units that are typically operated on alkaline or lithium type batteries. Most studies conducted can state battery life lasts between 3-4 years in most flush valves. For hardwired flush valves, these units tap into a facility's electric supply once installed. They are powered through transformers that can convert the electric current down to the proper amps required to activate a flush valve. They are also hands-free, sensor-operated devices.
Wall-hung lavatories are mounted to the wall with use of wall brackets or can be installed with concealed arm carries that rest behind the wall, extending steel arms that then get mounted through the back side of the lavatory fixture.
Counter-top lavatories are installed by either dropping in through the top of a counter/granite top or mounted underneath a counter top
The lowest flow rates in the market today are either 0.5 gpm or 0.35 gpm, although the standard in most cases is either 1.5 gpm or 1.0 gpm.
The top ledge of the lavatory must be at least 34” from the floor in order to conform to current ADA requirements.
By using a thermostatic mixing valve in combination with a faucet this unit is designed to monitor inlet conditions and hold the outlet temperature constant based on a variable set point from 96 degF [36 degC] to 120 degF [49 degC].
Laminar flow outlets distribute water from the faucet without absorbing air first. This give the flow a clear, stream like pattern, and prevents potential bacteria or germs in the air from getting pulled into the water supply as the faucet is distributing water. These outlets are often specified in healthcare and education applications. Aerated flow outlets pull in air and mix with the water as the faucet is dispensing giving a more rigid stream of water.
