Regardless of the cause, it might be essential to call a plumber to conduct further inspections whenever you hear loud knocking noises. In this blog, you will learn why you might hear the knocking when you turn on the hot water, among other scenarios. Hence, read on to get some insights into what you should do and whether calling a plumber will be necessary. Below are some of the scenarios and causes of the banging sound.
Knocking Sound Just After Turning On the Hot Water
Do you hear a constant knocking and loud sound whenever you turn on the hot water faucets? Then the main culprit, in this case, is substandard CPVC piping. The pipes’ material usually contracts and expands whenever the heated water starts flowing through. This is the leading cause of the intermittent knocking sounds you hear behind the walls of various rooms at your Denton, TX home.
You must understand some homes still use CPVC pipes for hot water supply. Hence, ensure that you have a plumber inspect the piping before you purchase a new home. Whenever you hear knocking and banging sounds, whenever heated water is running via the pipes, they might be caused by a bad connection in the lines.
Further, if this arises in tight spaces where the sound can resonate, the piping was improperly installed. Enough insulation might not have been placed on the pipes. If the CPVC pipes are of good quality, they will never cause such issues, even at high pressure. Hence, if your home uses CPVC pipes and you have noticed that they haven’t been insulated, have a plumber install an insulation layer around them.
If you notice uncharacteristic sounds emanating from the pipes, giving the pipes a breathing space and finding their source is the only solution. Have a plumbing expert replace the CPVC pipes with copper pipes that work better with hot water. Installing new piping involves cutting through the walls and CPVC piping, so it is recommended that you let the work be done by a professional.
Knocking Sounds from the Pipes When Cold Water Flows
High pressure is the leading cause of the knocking sound when the cold water runs via the piping. The high pressure arises when some sections of the piping aren’t tight enough to handle the pressure properly. The high flow rates can result in turbulent flows that rattle and shake the pipes as they try to keep up with the water that is mobbing at a fast rate. This process ends up making the pipes produce loud knocking and banging sounds.
Whenever you notice that the water pressure at your home has increased, you must have a plumbing professional check the pressure of the incoming water supply. The professional might also install a pressure gauge that you can use to check and control the water pressure. If the water pressure is over 80 PSI for over 10 minutes without lowering it for over 2 hours, it is time to call a plumber.
Knocking Sound Immediately After You Turn Off the Cold or Hot Water Faucets
Have you noticed that your pipes produce a loud banging sound whenever you turn off the faucets? That is most likely caused by a phenomenon called water hammer. This phenomenon normally manifests as a loud “hammering” sound from the bathroom piping whenever you flush a toilet or suddenly turn off a faucet. A water hammer comes up when the incoming water is suddenly reflected at a valve. The sheer force and pressure have no place to go, resulting in that loud sound.
Water hammer not only results in the banging sound. It might also burst the pipes or crack the foundation depending on the extent of the force. It also may damage appliances such as water heaters and dishwashers. Therefore, you should call a plumber in Denton, TX, whenever you notice a water hammer. The professional will inspect the plumbing system for the location of the issue and tighten any loose piping. The professional might also insulate the pipes to keep them safe.
Intermittent Loud Knocking and Banging Sounds Whenever All the Faucets Are Off
Loud banging and knocking sounds when the hot or cold water flows via the pipes have been discussed above. But what could make the pipes produce a banging sound when all your faucets are off? This is most probably caused by sediment accumulation in your water heater. Sedimentation is among the leading nemesis of your water heater.
The knocking sound that you hear means that there has been excessive sediment accumulation. It is produced when the sediments bang on the walls of the water heater tank. A water heater features two heating elements, one at the top and the other at the bottom. Whenever the sediments cover the heating element at the bottom, its heating efficiency is reduced. For this reason, homeowners are advised to have a plumber flush their water heater tanks yearly to remove any accumulated sediments.
