My first two faucet videos below are actually parts 1 and 2 of installing an undersink water filter. In part 1, I'll show you how to replace the old single shut off valve (angle stop) and replace it with a two port unit that will make installing and servicing the water filter a snap!
Glossary items for Faucets
Lavatory Pop Up
Is the name for the stopper in a Lavatory Basin that has a push/lift rod in the faucet body that operates the up n down action of the stopper (Pop Up)
angle stop
A shut off valve. Used for fixtures such as sinks and toilets. 1/4 turn type are ball valve type and generally better. A single outlet port is best. If two supplies are needed it is best to have two separate angle stops, or a double handle / doublestop.
ball valve
A valve who's shut off part is a spherical ball with a passage cut through it. Standard port ball valves have a smaller port thru the ball than the pipe size they are on. Full port ball valves have a full port that matches the inside diameter of the pipe they are sized to. Ball valves turn on and off in 1/4 turn (90°), and provide an unobstructed path for the fluid to flow through.
Diverter Spout
A Tub Spout having a knob to lift, push, pull or something to stop flow of water and send the flow to a shower head.
dynamic
As used in pressure with water that is flowing. Dynamic pressure is less than static, and lower due to relieving of pressure out discharge point. The more discharge the lower the pressure. No discharge, all pressure is present that exists. As used in pressure measurement the dynamic pressure of a fluid is equal to 1/2 the density x the velocity squared.
Over flow
An often miss used term, sometimes used to denote an Air gap, a Pressure and Temperature Relief Valve (PTRV) or T&P for short. Neither of these are Overflows anymore than air bags are brakes to a car. Tubs and lavatories often have an overflow but not required to. An overflow on a tub is also an access to clean out the fixture trap and arm. It is the round 3" dia. trim piece having one or two screws. Toilet Tanks have an overflow that flows into bowl(the 1"dia. vertical tube in middle of tank) See Air Gap and PTRV for more on them.
P Trap
The J bend and Trap Arm that are under all sinks/showers/drain fixtures. Sole purpose is to trap sewer gasses from venting up from the drain into the room. The P Trap keeps water in it from its shape having a dip or the P on its side to retain water.
PTRV or T&P
Water Heaters need a safety device in the event the heating controls do not stop at set/safe temperature. A temperature and Pressure relief Valve AKA Pressure and Temperature relief Valve is this device. This valve is NOT meant to operate unless to avoid an explosion. When a PTRV is weeping call a professional ASAP.
Union Fitting
A fitting that is usually 3 parts, one on each side of a nut that connects the other two. The other "two" one each connects to either Pipe and a valve or just pipe on either end. The reason to have a Union is so you can loosen the connecting ring and remove a valve or make free the pipe that would otherwise be bound. A good example of a Union is the swivel on a garden hose, another is not plumbing, but functionally the same, The seat belt latch !or a Vacuum cleaner hose connector.
Water Pressure Regulator
A Regulator is commonly used to reduce high pressure coming from the utility line/ Meter. Street pressure is often too high for your house or your landscape piping. Code requires <80psi. Partially closing a valve to reduce pressure does not reduce the water pressure when water is not moving, and therefore Pressures above 80 psi need a pressure regulator to reduce to below 80 psi. Less pressure less water use, Conservation requires lower pressures to avoid blow out pipes and excessive water use.
