2. Pressure-balanced valve - Wikipedia

   en.wikipedia.org/wiki/Pressure-balanced_valve

   It has a diaphragm or piston inside that reacts to relative changes in either hot or cold water pressure to maintain balanced pressure. As water pressure drops on one supply line, the valve reduces the pressure in the other supply line to match. A side effect of this is that the pressure and flow at the shower head or tub spigot will drop twice ...

3. Plumbing fixture - Wikipedia

   en.wikipedia.org/wiki/Plumbing_fixture

   The visible water surface in a toilet is the top of the trap's water seal. Each fixture drain, with exceptions, must be vented so that negative air pressure in the drain cannot siphon the trap dry, to prevent positive air pressure in the sewer from forcing gases past the water seal, and to prevent explosive sewer gas buildup.

4. Air gap (plumbing) - Wikipedia

   en.wikipedia.org/wiki/Air_gap_(plumbing)

   To further illustrate the air gap, consider what could happen if the air gap were eliminated by attaching a hose to the faucet and lowering the hose into a sink full of contaminated water. Under the right conditions (if the water supply loses pressure and the sink is higher than the point at which the water supply enters the house, for instance ...

5. Tap (valve) - Wikipedia

   en.wikipedia.org/wiki/Tap_(valve)

   Also, the tortuous S-shaped path the water is forced to follow offers a significant obstruction to the flow. For high pressure domestic water systems this does not matter, but for low pressure systems where flow rate is important, such as a shower fed by a storage tank, a "stop tap" or, in engineering terms, a "gate valve" is preferred.

   If you have a leaky faucet, you could receive a refund from your water company. All you need to do is fix or replace the faucet and submit proof to your water company.

7. Valve leakage - Wikipedia

   en.wikipedia.org/wiki/Valve_leakage

   Valve leakage refers to flow through a valve which is set in the 'off' state.. The importance of valve leakage depends on what the valve is controlling. For example, a dripping tap is less significant than a leak from a six-inch pipe carrying high-pressure radioactive steam.

   I like the fact that the chemical only goes into the bowl, not the tank. Saves the parts inside the tank. Easy to change the cartridge without having to shut the water off."

9. Siphon - Wikipedia

   en.wikipedia.org/wiki/Siphon

   Should the pressure within the water supply system fall, the external water may be returned by back pressure into the drinking water system through the faucet. Another possible contamination point is the water intake in the toilet tank. An anti-siphon valve is also required here to prevent pressure drops in the water supply line from suctioning ...
