The fill valve in your toilet controls water flow into the tank after you flush. If your fill valve is worn out or faulty, it may cause a whining sound after flushing. You can easily check if the fill valve is damaged: just open the tank, find the valve, and check for leaks, cracks, or debris.
The most common sign of a broken fill valve is water constantly running. You may be able to hear a humming noise or see water pouring into your toilet bowl all the time. However, it is possible for a valve to just develop a tiny leak that barely allows water to trickle through.
The noise you are hearing is actually the sound of the toilet fill valve topping off the tank. Your flapper is most likely leaking slowly and needs to be replaced. Water is slowly leaking around the flapper and when it gets low enough in the tank, the fill valve comes on and fills water back up until it shuts off.
A constant hiss is usually due to a fill valve problem. It is either sticking internally or has worn out parts. It can also be related to the flapper not seating/sealing completely which allows water to constantly leak out the center hole.
They measure the water you use with a meter to figure out your bill. If your pipes are hissing because there's a tiny leak somewhere, then that'll increase your bill, as the leak uses water.
Ghost flushing, or phantom flushing, occurs when your toilet tank refills independently without anyone pressing the handle. Water leaks from the tank into the bowl, causing the fill valve to activate periodically to refill the tank. It's similar to your toilet flushing itself, but it's just refilling.
The ball and armature within these valves vibrate during the tank refill process, resulting in a high-pitched whistle. Fortunately, a simple adjustment can often rectify this problem, but if left unattended, it could lead to complete fill valve failure, necessitating professional intervention.
Generally, it's a good idea to consider replacing the toilet fill valve every 4 to 5 years.
Valve Replacements: Valve replacements cost $50–$150 and resolve noisy or slow toilets. The fill valve refills the tank after each flush, the shut-off valve controls water flow, and the flush valve controls water coming from the tank to the bowl.
Fill valves typically have a lifespan of 5-7 years, depending on the type of water you have.
the symptoms for a fill valve are, they leak, they do not turn on, and they do not turn off. the symptoms for a bad flapper or disk are, they leak, they do not seat properly, they stick to the seat, and are not the correct size.
Phantom flushing: If the toilet makes a flushing noise when not flushed, you may wonder if your house is haunted. Fortunately, the reality is much less spooky than this. Odds are the flapper is worn out and not creating a tight seal between the tank and bowl.
The fight or flight response is a complex set of reactions that can be caused by fear and by anxiety. Flushing, or reddening of the face and/or other body parts, is one of the many side effects of these reactions.
This sound can happen intermittently and occur every few minutes or every few hours. Such a refill sound is usually alerting you that your toilet is losing water, either internally (if there's no water on the floor or exterior of toilet) or externally leaking if you see water outside the toilet.
Knowing how to replace a toilet tank fill valve isn't hard to learn. Most do-it-yourself homeowners can handle this project in about 60 minutes. All you need is the most basic understanding of how toilets work, a replacement fill valve kit, and the instructions above.
The fill valve regulates the water level in the tank. It utilises a float that rises or falls with the water level, opening or closing a valve that allows or blocks water from entering the tank. The flush valve controls the water flow from the tank to the bowl.
This is often an issue with the refill valve. Either it's clogged with debris, or it needs to be recalibrated or replaced. You're likely hearing a hissing noise associated with a slow fill because the refill valve only allows a little water into the tank instead of shutting off as it should.
If your water usage is unchanged, your city hasn't implemented a rate hike, and you have a high water bill with no visible leaks, the problem may be that you have an issue with your water meter. This isn't a common problem, but it's also not unheard of. To test your water meter, turn off your water.
On average, approximately 70 percent of that water is used indoors, with the bathroom being the largest consumer (a toilet alone can use 27 percent!).
