Home Paul McElrath - ElbowYoke Vent ~ A pipe connecting upward from a soil or waste stack to a vent stack for the purpose of preventing pressure changes in the stacks.Piezo Switch ~ The electronic switch the bather uses to control the whirlpool and optional heater. This switch, based upon the piezo-electric effect, generates a voltage when pressure is applied to it. N P S H A ~ Net positive suction head available to prevent cavitation of the pump. It is defined as: Atmospheric pressure + gage pressure + static pressure - vapor pressure - friction loss in the suction piping. Paul McElrath - About Plumbing ToolsSuction Static Lift ~ Same as Suction Static head. This term is only used when the pump centerline is above the suction tank fluid surfaceGalvanic Action ~ The phenomenon of corrosion of an anode (positive terminal - like on a battery). When two dissimilar metals are immersed in an electrolyte, an electrical potential will exist between them. If the two are in an electrical contact, a current will flow. The metal that becomes the anode (negative) of this cell will corrode and dissolve while the cathode (positive) will be protected from corrosion. Integral Stops ~ Stops that allow the owner to shut off water supply at the faucet for maintenance without shutting off the water supply to the entire house.
