no, faucet water gets checked by health enspectors and water from the refrigerator is not checked. so, faucet water is healthier! who knew
Tap water comes from the water faucet. It gets to the water faucet from the water treatment plant through the water storage takes and lines.
I have seen this type of thing happen when there is a bit of junk in a line that falls back when the flow has stopped, and then move back with the flow to stop it when it gets to a point where the water is restricted. More often, I have seen it to be just something odd about the faucet making it creep off from the flow of the water going through it.
the Evaporation
Your hot water line needs more insulation probably. It sounds like your hot water is cooling before reaching that faucet. It may be that the one faucet is not able to turn all the way to hot until you adjust the faucet (usually in the handle) of a 10 year old or newer faucet.
Evaporation is the process by which a puddle gets smaller as the water heats up and turns into vapor, escaping into the atmosphere.
The volume of water that comes out of the tub faucet is much greater than the volume of water that comes out of the kitchen faucet. Let's say that the bathroom is twice as far from the water heater than the kitchen, so twice as much water has to be run to get the hot water. If the tub faucet allows more than twice as much water to pass through, then it will get there faster.
I have this problem with my shower head, what I do to fix it is turn on the sink in my bathroom to hot, this usually shuts it up
Air in the water lines. Everytime water is shut off for plumbing repair , some air gets in. If this is an ongoing problem for no apparent reason, you probably need a plumber.
If water gets under a faucet washer it can cause a loud vibration when the water is turned on. You either need to find a proper replacment or get a new faucet.
Either replace the washer on the hot side in the faucet (or buy a new washerless faucet), replace the "angle-stop" with a "quarter-turn" style, or install a "water hammer arrestor". (There is a real convenient style on the market, it fits between the incoming nut at the angle stop and the thread on the body of the stop itself).
If it is at freezing temperature, then you have an issue with uninsulated pipes.
