One of the most well known plumbing noises is water hammer. It sounds like a hammer hitting pipes because water going through the pipe hits a bend in the pipe causing a shockwave. Water hammer is often caused by quick-closing valves, like those on washing machines and dishwashers, but the sudden shutting-off of water flow to toilets or by faucets can cause it as well. Whatever the culprit, the result is the same -a loud bang or banging sound. This impact can create pressure, and over time these repeated impacts and the pressure they cause can damage pipes and valves, weakening them and pipe joints.
Over time, these impacts can create pressure which can weaken and damage pipes, valves, and pipe joints. In more modern homes, the solution has been to install air chambers, devices filled with air, which act as cushions. But over time, these devices can fail. Over time, the air in the chamber is absorbed by the water, which then takes its place.
The sudden onset of water hammer in a home is generally a sign that its plumbing's air chambers have filled with so much water that they aren't working anymore. It's possible to fix the problem if the affected chamber(s) can be located. First, the water needs to be turned off at a point before it reaches the affected chamber(s), then the problem valve or faucet needs to be opened to allow all the water in it to be drained. Air will replace it and restore the cushion.
If water hammer suddenly starts, it's often because one or more of a home's air chambers have filled with so much water that they no longer work. It's possible that they can be repaired instead of replaced. First the waterlogged air chamber(s) must be located. The water supply needs to be turned off prior to reaching the chamber(s), then the faucets and valves ahead of the chamber(s) need to be opened to allow the water in the pipe and chamber to drain. Air will then flow into the chamber restoring it.
If water hammering suddenly starts, the most likely cause is a home's plumbing system's air chambers have filled with water. It's possible for a homeowner to fix the problem themselves if they can locate the water-filled chamber. The water needs to be turned off before it gets to the chamber, then the problem faucet or valve needs to be opened and allowed to drain thoroughly. After all the water drains from the chamber, air will replace it and restore the cushion. If the air chamber is located below the vertical level of the outlet, it may be necessary to drain the main home's water supply lines so that the chamber can fill with air. If the air chamber won't drain properly, it may be clogged with tuberculation, scale, or some kind of residue from minerals or chemicals dissolved in the water. Sometimes it's possible to clean them out, but if not they should be replaced.
If the home's plumbing system doesn't have air chambers built into it, reducing the water pressure may be a solution, this could be accomplished with the installation of valves that reduce the pressure of the lines coming into the house. But this might not work if it leads to such low pressure that faucets and valves on upper-floors only have a trickle of water coming out of them. If pressure reduction doesn't work, it may be necessary to install air chambers into the current plumbing system. Many of the chamber devices currently on the market have a built-in valve for letting air refill. - 15254
