Problems with the work of plumbing in the house arise quite often. The most common phenomenon that causes discomfort to residents is the appearance of unpleasant sounds in the system. Let's look at why the water pipes are buzzing when the tap is turned on?
Poor installation of system elements
Why is the crane humming several times a day? This may result in the plumbers making mistakes when installing or repairing water pipes. If unpleasant sounds arise behind the wall, it is possible that the locksmiths who served the system with their neighbors did not connect the pipes tightly or insulated poorly. To determine exactly why the tap is buzzing, first you need to go down to the basement and check if the water supply elements are tightly fixed here. After making sure that everything is in order, it is worth contacting the neighbors and together detecting poorly fixed pipes. By eliminating installation flaws throughout the riser, you can forever forget about the problem.
Close pipe arrangement
Why do the pipes buzz when you open the tap? Often this phenomenon is observed in cases where the elements of the water supply are in direct contact with each other. To fix the problem, you should find closely located pipes. If it is impossible or difficult to change their configuration, it is enough to wrap each water-conducting element with special polyvinyl chloride insulating covers, which can be purchased at any plumbing store.
Excessive system pressure
Why is the crane humming when turned on? This can lead to the presence of excess pressure in the water supply system. You can identify the problem by abruptly opening the tap. If streams of water frantically break out of the hole, then this is precisely the nuisance.
Excessive pressure levels in the water supply system over time can lead to depressurization of certain structural elements and flooding of housing. To reduce the load on the pipes and remove annoying sounds, it is recommended to resort to the installation of a special pneumatic chamber. The latter is mounted at the junction of the mixer with the pipe and takes over pressure.
A final check on the existence of just such a cause of hum and buzz in the system will allow the plumber to call, which will determine the level of pressure in the water supply system. Normally, the indicator should be 2 atmospheres. In this case, the taps, dishwasher and washing machine will not be exposed to destructive effects. If the system pressure is 6 atmospheres or more, this is a reason for complaining to the service provider.
Pipe clogging
Why is the crane humming when it is closed? This can cause clogging of the paths that conduct water in the system. The liquid that remains in the pipes under pressure even when the valve is closed, passes through the clogged sections, causing a rather unpleasant noise.
Reducing the inner diameter of the pipes is known by the definition of "heart attack pipeline." There is a phenomenon in houses in which for a long time there has been no maintenance or repair of capital engineering systems. Inside the pipes are overgrown with rust, salts, all kinds of garbage accumulates here. In the most difficult cases, they resort to installing new metal pipes or installing plastic joints to fix the problem.
How to determine that the cause of uncomfortable sounds lies precisely in the presence of clogging inside the pipes? To diagnose a blockage, it is necessary to dismantle any section of the water supply and look inside. The presence of plaque and dirt on the walls of the pipes will confirm the guesses.
Clogging in pipes can also be eliminated by mechanical or hydraulic flushing. In the first case, it is worth releasing water from the problem area and use a thick wire, at the end of which a metal brush is fixed. For hydraulic flushing systems resort to the use of a powerful circulation pump, which is able to quickly drive water through pipes under high pressure.
Old, damaged pipes
Why is the
water tap buzzing
? The regular occurrence of unpleasant sounds in the presence of an optimal level of pressure in the system and the operation of serviceable mixers can lead to obsolescence of the entire water supply. The best solution for dealing with trouble is replacing rusty, leaking sections with new pipes. However, in some cases, this approach does not completely resolve the problem. In such a situation, the only option remains a radical replacement of all pipes in the riser. To reduce costs, it is worth joining forces with neighbors.
Mixer gasket damage
Now consider the most common reason why the crane is buzzing. The most common problem is defects on the mixer gasket. The latter may be worn, improperly installed or defective.
To fix the problem, do the following:
- Open the tap for hot and cold water in turn. This will reveal exactly where the damaged gasket is located.
- Shut off the water supply in the apartment.
- Disassemble the mixer and remove the damaged gasket.
- Purchase a new structural element in the plumbing shop and install it.
- Collect the mixer, turn on the water and check if the buzz in the tap has disappeared.
Insufficiently secure water hoses
Why is the tap in the kitchen humming? To find the reason, it is worth checking the hoses that are led to the mixer under the sink. In this case, it is necessary to open the taps of hot and cold water in turn. Having determined which of the hoses causes a buzz, you need to pinch it with your hand or isolate the connections using tools.
Cartridge malfunction
Most modern single lever mixers contain a cartridge that is responsible for the distribution of water flows. It is likely that the cause of unpleasant sounds in the plumbing system lies in its damage.
To replace the cartridge, you will need the following tools:
- adjustable wrench;
- set of screwdrivers;
- thin blade knife;
- hexagon.
Before performing repair procedures, it is necessary to shut off the water in the apartment. Then, use a screwdriver to pry a button that indicates which side the hot and cold water supply is on. Next, unscrew the screw holding the cartridge with the hexagon. In conclusion, using an adjustable wrench, it is necessary to unscrew the clamping nut and remove the structural element.
You can pick up a cartridge similar to the one available at a plumbing store. Having completed the purchase, it remains only to assemble the system in the reverse order, resorting to the use of the above tools.
Hose leak in the shower
Why is the faucet in the bathroom buzzing? One of the common causes of this phenomenon is the presence of leaks in the hose, which connects to the shower head.
To fix the problem, first of all, it is worth checking whether all the same gaskets are damaged. If the reason lies in this, you need to replace them.
Sometimes unpleasant sounds when turning on the water in the shower lead to a rupture of the hose itself, namely its inner rubber tube, which is located in the middle of the metal sleeve. To deal with trouble, you need to patch the gap with a patch. However, for those who do not want to burden themselves with extra work, it is best, of course, to buy and install a new hose.
Finally
In the material presented, we examined the most common causes that cause buzzing, whistling, and other unpleasant sounds in the plumbing system. These methods for solving individual problems will allow you to independently eliminate the discomfort.
However, resorting to repairing plumbing is recommended only to those people who already have experience in performing such work. After all, rash actions can affect the functioning of the entire water supply system. If improper repairs are carried out, not only water leakage is possible, but also a serious emergency. Therefore, in some cases, to eliminate unpleasant sounds in the tap or elements of the water supply system, it is worth resorting to the services of professional masters.
