Is the water not hot? Or no water coming out the hot tap? not comming out at all
The water is probably frozen in the pipe
If this is happening on one tap only then you have to turn off all water and take the tap and the shutoff valve under it apart. The problem may be a broken washer.
Something is wrong in the control unit. Take it apart and remove central part, take to store, get a replacement kit and fit it.
No, never drink hot tap water, but cold tap water is actually really healthy for you!
hot filtered water
Hot water is simply water that is hot, regardless of where it comes from.
If the refrigerator water is filtered, then it would be different from the tap water coming from the sink.
Deposits from water heater.
it depends how hot the water is
The most likeliest answer to this question would be that your hot water heater is unfortunately rusting or perishing from the inside, no amount of cleaning will help. your only option is to replace the hot water heater.
i think its because when you turn on the hot water tap the dirt in the tap has gone because the dirt loses the stickiness and hot water gets rids of stickiness
corrosion somewhere between the boiler and the tap (or in the boiler) is most likely. Give it a good clean- look on the internet for how to get the rust off it. Good luck sexy!
There is a shutoff valve on the cold pipe going into the H/W tank, if you close it no water will come out of the tank. There should also be a shutoff valve on the wall below each faucet/tap.
It is broken
It should be the same temperature that you set your hot water heater.
This occurs when your hot water heater is either broken, disconnected, or has exhausted its supply of heated water. In cold weather, heated water may be cooling in the pipes on the way to the faucet, especially when it has just been turned on.
Most probably the "sediments" have settles to the bottom and as the hot water is taken off the top of the heater there will be none in the tap water. Hot water will contain less calcium and other impurities (they fall out and become those "sediments" but hot water may also dissolve other compounds from pipes. I use hot tap water in my coffee pot.
You will digest it.
It depends on the temperature of the tap water.
That depends on your location (where your tap water is coming from) and the source of the bottled water. Aside: I once lived in a place where my tap water and the local popular bottled water came from the same place. Bottled water comes from a tap somewhere!
see a plumber
It's probably because the tap washer is made of the incorrect material for a hot tap which must have a degree of temperature resistance. If not, the tap washer could swell and expand when the hot water flows, thus cutting off the flow.
