What causes hissing sound in water pipes?
One of the most common reasons for noisy pipes is air. If too much air is being pushed through pipes with running water, you’ll hear rustling, hissing, and loud whistling noises when a faucet is turned on or the toilet is flushed. This is usually not a serious problem. Copper pipes expand and contract with temperature.
Is it normal to hear water running through pipes?

Turn on both the hot and cold water to about 1/8th of the way on all the faucets. Leave the water running for about two minutes. Start from the lowest faucet in the house to the highest faucet. This allows the water pressure of the system to force all of the air from the pipes and out through the faucets.
How do I get rid of an airlock in my water motor?

Leave to run for several minutes and then make sure to turn off the air locked tap first.
Why does my hot water keep getting air locked?
What causes an airlock in the hot water system. A cold or hot water airlock can be cause by the tank running dry or air bubbles with the hot water system from a heating system where the pipe work runs up and then back down causing the air to trap and not vent out as to what should be happening.

Should you hear water in baseboard?
It should be silent, the only sound you hear is maybe the radiator expanding. But if there’s an air pocket inside the radiator, then the water gurgles and bubbles as it tries to run along the bottom of the pipe.
Why can I hear water running through my radiators?
When the pump starts to drive water through the system, a bubble of air forms as water flows over or around an irregular surface in the radiator. That can produce a “gurgling” sound. Have a contractor check it. Also ask if the pump speed is too high, which could cause gurgling.
