In general, when turning on a faucet or flushing a toilet, you can sometimes hear strange noises from the Heat Pipe . In fact, these noises are different, some sound like banging while others may like a loud pitch noise. Then, what is the cause of these noises and creaks?
When hot water flows to each plumbing fixture or faucet it heats up the pipe through convection, this causes the pipe to expend. Also, if the hole or penetration is smaller than it should be will cause the excessive noises as well. You know, holes and penetrations to which the pipe travels through should be larger than the pipe to allow for expansion an contraction, by following this method, you may avoid the aggravating noises that some plumbing can make.
Want to solve the noisy plumbing? Try to isolate the suspected noisy pipe. Inspect and ensure that pipe is not in contact with any part of a wooden structure, if so you may have to cut that section of pipe out enough allowing yourself enough space to enlarge or re-drill the hole approx 3/8 to 1/2 larger than that pipe. However, before doing any drilling, you’d better check with your local building codes as this information is not meant to be instructional or take the place of a licensed technician or carpenter.
Besides, loose pipes are more likely to cause vibrating pipes. When a faucet or valve is opened, pressurized water is directed towards the pressure drop or opened faucet. When pipes are loosely clipped they cause the pipe to vibrate as the pressurized water passes through that section pf pipe. This can be sometimes easily fixed by installing additional hangers or supports needed. You may also need to use pipe insulation. Install this around the pipe keeping it from being in contact with any wood or metal objects such as the house framing or other heating pipes and ducts as these tend to vibrate from the operation of a heating boiler or furnace.
Besides, a loose or broken faucet or faucet screw may cause pipes whistle when you open a faucet. Then, try to isolate the problem by shutting of valves to your sink faucets and toilets. You can open up fixture at a time allowing you to locate the problem, by this you can do a process of elimination and locate the plumbing culprit whether it be a loose washer or sometimes a faulty shut off that may have sediment that is blocking the free flow of water.
In addition, banging pipe is a common problem in older plumbing system for years ago many water systems were not equipped with air chambers which is also known as water hammers. These are installed typically at the highest point of the plumbing system and fast closing valves such as a bathtub or shower faucet. When the plumbing system is initially charged with water these dead end pipes catch air that is already in the filling pipes allowing the rushing water to be cushioned when the water abruptly stops when the valve is shut.
