A toilet makes a hissing sound when the chain prevents the flapper from closing or when the chain is so long that excess chain gets caught under the flapper. A chain that is too short will keep the flapper in a slightly raised position, allowing water to pass out of the tank—creating a toilet hissing sound.
Sometimes toilets make strange noises like gurgling, screaming, hissing, etc. These noises are mostly related to the movement of air or water. If the toilet hisses, it is probably because water or air is leaking from the fill valve. In any case, if the valve is not shutting properly, the toilet may leak.
It's happened to nearly all of us — you've walked into your bathroom and noticed a slight hissing sound coming from your toilet tank area. This sound is often ignored, but doing so could cost you with increased water bills over time. A faint hissing sound in the toilet tank is often due to a faulty fill valve.
Because a hissing toilet has different reasons for issues that might be wrong, there is a range of costs for fixing it. On average, it costs between $130-$310 dollars to fix the toilet.
The toilet's flush valve will typically last 6-7 years. A toilet fill valve might only last four to five years. In general, you should expect to replace the parts in your toilet every so often while keeping the actual bowl in place.
If your toilet is leaking from the water supply, the water supply line may need repairing. This is a common and inexpensive repair for your plumber to make. If the toilet rocks when you sit on it, your plumber may need to replace the wax seal.
You may think that a cracked sewage pipe is the biggest contributor to a spike in your water bill; however, that isn't the case. While sewage pipe damage does contribute to higher water bills, a running toilet can waste an entire gallon of water in about 30 seconds.
If excess water is flowing into it, this is the cause of the hissing noise. In this case, the fill valve is faulty, and you will want to get it fixed as quickly as possible because all that water flowing down the overflow tube is costing you extra money every month.
Since the water flows down the sewer, leaking toilets don't necessarily leave any signs of a leak, until you get the bill. The average leaky toilet can waste about 200 gallons of water per day. That's over 6,000 gallons a month ($70.06*) for just one leaking toilet!
This is most likely due to a worn out flapper, but could also be caused by a stuck chain or float (either a ballcock or float valve.) If your toilet is making random noises every few minutes, it means that at least part of the flush is executing.
If something is blocking one of your sewer lines or a vent stack, you'll start to get bubbling in your toilet bowl as air tries to escape. There are two main reasons a vent pipe might clog, one being a clogged sewer pipe and the other being a blocked vent pipe from another obstruction on the roof opening.
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.
A clogged drain line can put pressure on the wax ring at the base of your toilet, which can break the ring and cause toilet leaks. If you suspect this is the problem, contact a plumber for an evaluation. They can unclog the drain line and get your toilet back up and running in no time.
The answer is YES, as clogs or blockages occur in drain pipes water backs up inside behind the blockage and can cause a pipe to burst, or slowly leak through seals and joints.
The sooner you start toilet overflow remediation steps like cleaning, drying, and sanitizing, the more quickly damage restoration can begin. A toilet overflow, like all water intrusion events, can cause devastating unseen damage to your home's structure.
Not literally, of course – but your water bill will skyrocket if your toilet is constantly running. More often than not, continuously running toilets are extremely easy and inexpensive to fix – you might just need to replace the flapper. A constantly running toilet also presents an increased risk of flooding.
Bathrooms: High efficiency toilets use 1.28 gallons per flush or less, non-efficient toilets use up to 5 gallons per flush. A silent toilet leak can be as small as 30 gallons per day (GPD). Larger leaks can be up to 6 gallons per min, equivalent to 11 billing units (BU) per day.
This can be a frustrating problem for homeowners or businesses to deal with since it can cause a rise in utility costs. It can also be a sign of an external water leak that could cause water damage if it is not taken care of quickly.
The most common place for a toilet to leak is at the wax seal. Replacing a wax seal may be as cheap as $50. Other common leak points are the tank and bowl which may cost $300 or more to repair. You should take care of leaks as soon as possible so you don't add water damage to the list of necessary repairs.
Leaking Around the Base of Your Toilet
The worst-case scenario is that the toilet leaks through the floor and causes damage to the room underneath. For this reason, it's best to involve a plumber to pinpoint the cause of the toilet leak and provide a quality solution.
According to Fixr, the average toilet valve repair cost is between $75 and $200 to replace a flush valve or up to $400 to fix a constantly running toilet. This includes the cost of the plumber's time for the toilet repair and the cost of the toilet parts.
