Quieting Noisy Toilets

You flush the toilet, and consider running for earplugs.  Sound familiar?  If your toilet has developed new sounds, you may need the services of a professional plumber who handles bathroom repairs.

Noisy toilets are best described as an increase in the noise after flushing.  The sounds are also abnormal, and many homeowners will describe these sounds as a loud, continuous gurgling noise.  If this describes the sounds that your toilet is making, you may have a faulty or broken fill valve.

Fill valves (also known as tank valves) are water valves that control the water for the refill (post flush) cycle.  This is the water that will actually fill the toilet bowl after it has been drained.  Fill valves eventually wear out, and it will sound like a large gurgling or continuous running in the toilet.

The fill valve is located inside the toilet tank.  When you remove the lid, you want to inspect a few different things.  Is there water in the tall column, or the fill valve itself?  There should be some water, but it should not be completely full.  If it is, the valve probably needs to be replaced.  When the fill water is too high, continuous running and gurgling will occur.  This not only wastes water, but can also be an annoyance to listen to.

A tank valve replacement is a simple repair by a local professional plumber.  Tank valves traditionally need to be replaced every five to ten years, and are relatively inexpensive repairs.  When you call the plumber, describe the steps you have taken and the exact sounds being made.  This will help isolate the problem and decrease your service call costs.

Replacing a Toilet Tank Valve

Inside your toilet tank is a valve that controls flushing and water flow into the tank.  A defective tank valve will cause the toilet to “run” intermittently or continuously.  Fortunately, a tank valve replacement is easy bathroom repair.

First, turn off the water supply and disconnect the supply line from the bottom of the toilet tank.  Place an old towel on the floor to catch any drips.  Empty the tank by flushing the toilet and then use a plastic cup or a sponge to remove the rest of the water.

Remove the tank lid and locate the valve which is usually on the left side of the tank as you are facing it.  Most modern valves look like  a tall plastic column with a cylindrical float around it.  If you have an older valve, the float may be a ball attached to the valve with a skinny metal rod.

Disconnect the hose that runs from the valve to the overflow tube.  Remove the large nut on the bottom of the tank that holds the valve in place and lift the valve assembly out of the tank.

Installation of the new valve is the reverse.  Install the rubber washer on the valve, place the valve inside the tank and secure it with the large nut and rubber washer on the bottom of the tank.  Be careful not to over tighten the nut.  Connect the water supply line to the valve.

Inside the tank, connect the little rubber or plastic hose from the valve to the overflow tube, then turn on the water supply.  Adjust the height of the valve as needed for proper flushing.   Check  flushing operation and look for water leaks, then replace the tank lid.
