A foghorn sound coming from the toilet usually stems from problems with the ballcock valve, also known as the flapper or toilet fill valve. Some toilets have metal ballcock valves that contain washers inside. If that washer gets loose or worn, it can cause this sound.
Lift the tank lid and flush your toilet while holding up the float, and if the foghorn noise goes away, you've located the problem. While this noise is a nuisance, it can be dealt with easily enough by taking apart the float and finding the loose valve, or calling a plumber to replace the component for you.
A defective refill valve or ballcock in a toilet can cause the noise. Suspect this if the groaning occurs after a toilet is flushed. The noise occurs as the toilet tank is being refilled. The remedy is to replace the valve, which is located at the left inside the toilet tank.
2) Foghorn
A foghorn sound in your plumbing could be a number of things. It may be a faulty ballcock in the toilet, a loose faucet washer, or a valve in the washing machine. It may also be permeating your entire house, in which case it could be from loose or old pipes or a malfunctioning regulator.
A worn-out flapper will allow water to leak into the bowl of the toilet, causing a slow leak within the tank. When the tank refills, it creates the vibrating noise you hear. Flappers tend to wear out even quicker when regularly exposed to chemicals used to clean the toilet.
If you hear gurgling when the toilet is trying to fill up, you most likely have too much air in your tank. Just open the filler valve at the back of your toilet and wait for about five minutes while it drains out some of its own water, then try refilling it again.
In most cases, the cause of toilet whistling can be a metal ballcock valve. These ballcock valves come with an armature and ball that begin to vibrate when the toilet tank refills after flushing. This vibration of valves causes the whistling sound that you hear.
Gurgling: A drain gurgling can indicate a blockage or clog. Gurgling from a shower or sink drain after flushing the toilet can mean you have a clogged pipe, the air in your pipes, or a much bigger problem – an issue in the sewer line. Gurgling noises also can be as simple as an incorrectly positioned heating pump.
Air in water pipes will sound like a hiss or pop. Alternatively, the trapped air can cause loud gurgling and prolonged vibrating noises. Other sounds are loud noises and bangs emanating from the pipes; this clearly indicates air traveling in the pipes.
They don't last forever, and when they start to fail, they don't seal properly and can set off an internal vibration that resonates through the pipes, which can carry the sound throughout the entire house! The fix is to simply replace the ballcock valve.
Toilets are like children, they should be seen and not heard. If you've got a moaning toilet, you need to replace the ballcock valve.
If you notice that after you flush your toilet is making a high-pitched noise as the toilet's tank is refilling, do not panic. The most likely culprit is the ballcock valve (also known as a float valve).
Humming. If your pipes sound like they're humming, it's likely a water pressure issue.
Turn on the water supply, make sure the stopcocks fully open, undo until it can't loosen any further. Taps will sputter as the pipes fill and water flows. Allow taps and showers to run until there's no more sputtering and waters flowing freely through every tap/shower. Flush all toilets a few times.
Will an airlock clear itself. Even if you run out of water, air should automatically clear in a well-constructed low-pressure water pipe system. The air should naturally climb to the top and discharge as the pipe system fills up.
STEP 1: Turn off your water supply at the mains. STEP 2: Turn on every tap in the house, starting at the top and working your way downstairs. STEP 3: Wait for the water to stop flowing out of the taps. STEP 4: Now flush all the toilets until no water is left there either.
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. Once the water is running from all outlets normally, turn them off.
A plumber inserts the hose and nozzle into your pipes and blasts high-pressure water through it to scour out the drain pipes. Not only does this move out clogs, but it also helps to remove hard deposits and hard water minerals. This is one of the most popular and safe ways of unclogging and cleaning out drains.
Ghost flushing, also known as phantom flushing, occurs when the toilet tank flapper is no longer creating a watertight seal with the flush valve, causing water to unnecessarily leak into the toilet bowl.
The cause of your toilet gurgling is a blocked line somewhere. A clog is creating negative air pressure, Instead of air flowing through the lines,the air pushes back and causes the gurgling sound. Sometimes, you'll also see the toilet water bubble.
