If you are in a house, with a well, it could be iron in the water. But more than likely you have some pipes or fittings that are old and rusting.
what does water come out when you drink it
The water on the cup most likely came from a water source such as a tap, faucet, or water dispenser. It could also have been poured from a water bottle or another container.
Iron must come into contact with oxygen and water for it to rust. This process is known as oxidation, where the iron reacts with oxygen in the presence of water to form iron oxide, the reddish-brown compound known as rust.
Open hot water on a faucet. Air will come out instead of water until air is all out, then water should flow as normal. May need to install expansion tank to take care of excessive air pressure build-up in water line.
Tannins are caused by vegetation decaying and leaching into the water supply. To know if you have tannins or if it is insoluble iron run the well for a little while and fill up a white cup, if the yellowish color never disappears then you probably have tannins in your water. You are more likely to have tannins if you are located near a body of water or in a forest area. Hope this helps.
A faucet.
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.
In cold weather, hot water may not come out of the faucet because the pipes leading to the faucet can freeze, causing a blockage and preventing the hot water from flowing.
Water continues to come out of the faucet when using the shower because the plumbing system in a house is designed to supply water to multiple outlets simultaneously. This means that water can flow to both the faucet and the shower at the same time without any interruption.

Faucet needs repaired.
If the sprayer hose screws onto the faucet, you can get a cap for that fitting. If it pushes into the faucet, I do not believe there is any plug available for that type. You have to have something on the hose fitting or water will come out when you turn the faucet on.
Water is coming down from upstairs or it is back pressure from the water heater. If it is the water heater, it can come out of either side of the faucet.
Unless there is a recirculating pump the hot water has to come from the hot water heater. Depending on how far away it is from the faucet, it can take 15 to 30 seconds for the hot water to get there. Since there is nothing in the pipe to keep the water hot, it cools down between uses.
Do all the faucets do this or just one. if its just one faucet its a problem with this fauset. If its all the faucets in the home its a problem with the main water line coming into your home.
mostly because of rust deposits
