A hissing sound means that the refill valve is still allowing a little bit of water into the tank because it has not shut off like it is actually designed to. So, when you hear your toilet hissing, take the lid off your toilet tank immediately.
A hissing sound can mean that the refill valve is still letting a tiny bit of water into the tank because it hasn't shut off like it's designed to. The valve shuts off automatically based on the water level in the tank. A faulty valve or one not set properly will keep running.
Issue 2: Prolonged hissing sounds coming from your toilet
To fix this, you'll need to check your float, refill tube and the ballcock/inlet valve. You want to see if your float is sticking or needs adjusting and make sure the refill tube isn't too far inside the overflow tube.
Whether it's an innocuous whistle or an ear-piercing scream, the high-pitched sound you hear as your toilet refills means either that the fill valve needs a new gasket or you need a new valve. Because replacement valves are inexpensive and easy to install, you're usually better off with the second option.
What Causes a Whistling Toilet? A toilet whistling after you flush it or randomly during the night is usually associated with a faulty fill valve. As a fill valve ages, its internal parts can deteriorate which result in the whistling, hissing sounds most folks encounter with this problem.
In general, plumbers charge between $72-$82 dollars per hour not including parts. 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.
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.
Try turning off your water supply to the toilet, remove the inlet valve, and clean the headseal washer. If the noise continues (and you have an older inlet valve), it may be that the rubber washer has deteriorated. In this case, you may need to replace your headseal washer, or the inlet valve.
A toilet making an air noise or a whistling or hissing sound is a sign that the fill valve is not closing and sealing properly, and air or water is leaking from the fill valve. If the fill valve isn't closing properly, begin by replacing it. If this doesn't solve your problem, call a plumbing professional.
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! Some toilets may produce a running water sound that is easy to hear. Some leaks are visible as a small trickle running from the rim to the water in the bowl.
Normally, the fill valve is located on a water supply pipe coming out of the floor or wall near the bottom left side of the toilet tank, near where the water supply tube connects to the tailpiece on the fill valve.
Hissing sounds
Hisses mean that the water pressure within your pipes is too high. The plumber may have a pressure regulator installed so that the water pressure remains within the normal range, eliminating the hissing sound.
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.
Luckily, once you know how to determine the cause of the leak, it's a straightforward process to fix your leaky toilet tank. You can do this by replacing the flush valve, fixing a leaky fill valve, or simply tightening the toilet's gaskets.

That's a leak. The cause may be a defective fill valve, but more often it's simply a misadjusted float. If the hissing isn't accompanied by water spilling into the overflow tube, air may be making the hissing sound. In that case, the toilet doesn't have a leak, but something is definitely wrong.
