Handles – Faucet handles typically come in 3 styles: knob, lever, and cross. Some manufacturers allow a customer to mix and match components to create a custom handle consisting of handle bases and handle inserts.
Handshower – A showerhead designed with a handle that’s connected to a water supply and a flexible hose.
Hanger – A device used to support pipes.
Hard Water – Natural water containing impurities in various proportions. Traditional hardness is a measure of calcium or dissolved solids in a solution, measured in parts per million. Hard water generally ranges from 100 to 250 ppm.
Hardness – The amount of dissolved minerals in water measured in grains per gallon (GPG). The most common minerals are calcium and magnesium.
Hardness Leakage – The presence of a consistent concentration of hardness in the effluent from an ion exchange water softener, often due to high concentrations of hardness or sodium in the water being treated (see Leakage).
Head / HD – (1) The pressure of water (or steam) in a closed system (see Pressure Head). It represents the differential in the gravitational force exerted by a liquid at two different depths. (2) Nautical slang term for toilet
Head Loss – The pressure of water as measured at a stated point, either in feet or in pounds per square inch (PSI).
Heat Exchanger – A heat transfer system
Heat Sensors – Heat-triggered devices on sprinkler systems that release the flow of water.
Heat Trap – Restriction of heat loss through water connections to a tank.
Hermetic – Completely sealed, especially against the escape or entry of air.
Hex Key – Allen Wrench
Hold Down – A type of pipe anchor consisting of a U-strap bolted at either end onto a horizontal plate.

Hubless – Same as no-hub. Cast iron drainage pipe with neoprene gaskets and clamps.
Hydraulic Pressure – Pressure that exists in a system containing non-compressible liquid.
Hydrolysis – The reaction of a salt with water to form an acid and a base.
Hydronic – System of forced hot water.
Hydrojet – Cold inlet tube designed to reduce sediment build-up and increase efficiency in a water heater.
Hydro Jetting (Service) – The process of clearing blocked pipes using high pressure water as a boring and flushing mechanism.
Hydrostatic Pressure – Pressure exerted by or existing within a liquid at rest with respect to adjacent bodies.
Hydrostatic Test – Test using non-compressible liquid under pressure at a level equal to or greater than the maximum pressure that will be utilized when in use, such as in steam boilers.
Hydrous – Containing water, water of crystallization or hydration, as certain minerals or chemical compounds.
Hygroscopic – Attracting or absorbing moisture from the air; changed or altered by this absorption.
Hypochlorite – The OCL anion; calcium and sodium hypochlorite are commonly used as bleaches and disinfecting agents.
