I'm afraid I'm not really handy and am going to be calling a plumber to have a look at this, but I wanted to see if anyone here has experienced something similar or knows what's going on.
This is the situation in a house in Toronto (Canada), so it's fairly cold, about -8 degrees Celsius today. Not sure how old the house is, about 25 to 30 years I guess? The basement kitchen sink has a simple Moen faucet. This faucet has only one lever, turn to the right for cold, turn to the left for hot, and pull the lever up to turn the water on.
Anytime the lever is set for fairly hot water, AND the lever is pulled up all the way so that the water's running as fast as it can, an unbelievably loud vibrating noise is heard from the pipe connected to this faucet.
The sound is extremely loud, it sounds like a jackhammer is being operated inside the wall.
As soon as the tap is shut (or either the water-flow or the water-temp. is reduced) the noise ceases.
As stated the problem only occurs when the water is anywhere past fairly warm AND the water is running full blast.
There's also a laundry sink in the basement. We've noticed that if the hot water tap in the laundry sink is running, then the kitchen sink's tap never makes any noise, the water can be run as hot as one likes at full blast without incident.
The laundry sink and kitchen sink are on opposite sides of the same wall (i.e. the rears of the sinks are attached to the same wall, one sink is on one side of the wall and one on the other).
So anyone have any idea what going on? I found some descriptions of a phenomenon called 'water hammer' but I'm not sure if this is it. (Water hammer seems to be a hammering sound that occurs when a tap is shut off.)
I think there may be air in the pipes. One time the City was doing some work in the neighbourhood and turned off the water supply. When the water was turned back on, we were told to run our taps for a bit to get the air out of the pipes and the same kind of jackhammering sound we now have was heard, but it stopped after the water ran for a bit.
I'd greatly appreciate your comments or suggestions.
