Common Toilet Repairs

Is there anything more frustrating than a toilet that does not work right?  Considering how often they are used and the fact that we do very little maintenance on our toilets until something goes wrong, it’s a wonder that they work as well as they do and break down so infrequently.

The vast majority of toilets in the U.S. are standard flush toilets that rely on gravity and water pressure to get the job done.  When you turn the flush lever, it opens a flapper valve at the bottom of the toilet tank that lets the water in the tank flow into the bowl and flush the waste down the drain.

Releasing the handle allows the flapper valve to close so the tank can refill with water.  A tank fill valve handles the job of refilling the tank with water.  The fill valve is operated by either a ball float at the end of a wire rod or a cylindrical float on the fill valve.  As the tank gets full, the float rises and activates a shutoff valve that stops the water from flowing into the tank.  At this point the toilet is ready for another flushing.

Most of the parts that make a toilet work are inside the toilet tank.  Carefully remove the lid and watch what happens inside the tank when you flush the toilet.  If the flush handle turns easily but nothing happens, the chain connecting the handle and the flapper valve has either broken or detached.  Re-connecting the chain will fix this problem.

If the toilet “runs” constantly or has “ghost flushes” you could have a leaky flapper valve, a bad fill valve, a leaking float, or the fill valve could be adjusted improperly.  If you are unable to tell which one of these is causing the problem, call your local plumber.  Your plumber will be able to easily identify the cause of the problem and quickly repair your toilet.

How to Prevent a Sweating Toilet

If your home is located in a humid climate, you may be familiar with “sweating” toilets.  Toilets sweat when humid air condenses on the outside of a toilet tank filled with cold water.  This condensate drips onto the floor and unless the problem is corrected, it can lead to mold and mildew growth.  Even worse, over time the condensate will find its way to the subfloor which will eventually rot away.

If you are having problems with sweating toilets, talk to your plumber about your alternatives.  Plumbers are experts in toilet repairs and may suggest one or more options for correcting a sweating toilet.

One such option is called an anti-sweat valve.  This valve is installed in the water supply line that leads to the toilet and mixes warm water with the cold water that fills your toilet tank.  Filling the toilet tank with warmer water will prevent the toilet from sweating.

If installation of an anti-sweat valve is impractical, you can try installing a foam liner on the inside of the toilet tank.  The foam liner is permanently glued to the inside of the tank to insulate the porcelain tank from the cold tank water.

A more effective solution is to install a low flow toilet or pressure assist toilet.  Pressure assist toilets have a second inner tank that holds the flush water.  This water never reached the outer porcelain so sweating is eliminated.  In some cases, just installing a low flow toilet will solve the problem.  A low flow toilet does not empty the tank with every flush.  Cold incoming water is diluted with the leftover warm water in the tank and sometimes this is sufficient to stop condensation formation.  The benefit will be lost if you routinely “double flush” your low flow toilet.
