What is the least understood and most ignored routine maintenance tasks?
Last Update: Sep 03, 2002

"That's a tough question, but we have found that few people recognize the importance of (1) checking and cleaning rim feed holes underneath the rim of the toilet bowl or (2) using the proper technique in the use of a toilet plunger to unclog the S-trap of the toilet bowl.NOTE (1): Inspect rim feed holes with a mirror, looking up under the rim where water from the tank enters the bowl. If these holes are blocked by mineral deposits or other materials, carefully remove these with a stiff, twisted wire or small nail all around the rim. It’s a lousy job, but somebody has to do it, and –when completed – the toilet should flush much better and the improved scouring action will help keep the toilet bowl cleaner. A few cups of household bleach poured down the overflow tube periodically (and left for 5 or 10 minutes without flushing the toilet) may eliminate the need to clean the rim feed holes in the future.NOTE (2): When a toilet plunger ("plumber’s helper") is called for and available to help free a clogged toilet drain, put the plunger’s cup below the water level [most of us are seldom lucky enough for it to be only water.] Push down gently but rapidly 5 to 10 times, then pull up quickly. Repeat this several times until the water drains freely. Use a pail of water to test the drain and repeat plunging as necessary. Under no circumstances should you flush the toilet before completing these procedures as the bowl may overflow. [If you thought cleaning the rim feed holes was no fun, try to avoid overflowing the bowl.]

FAQ Introduction
Common Toilet Troubleshooting Steps and some Frequently Asked Questions.
How long should it take to fill the tank and how can that be regulated?
The time to fill the tank varies with the design and size of the tank.
Why do toilet suppliers caution against over-tightening the nuts on toilet tank fixtures and trim?
Toilets are made of vitreous china, an exceptionally strong and durable material but one that can crack if subjected to a sharp impact or excessive stress.
What is the best way to adjust the water level in the tank?
The techniques vary by design among toilet fill valves.
Why must the refill tube always be kept above the water level?
How important is it to flush the line before or when installing a replacement toilet fill valve?
What are the leading causes of premature failure of all toilet tank fittings and what are the implications?
Considering Cutting the Overflow Tube Below the C-L Marking on the Fill Valve?
Some fill valve suppliers and "how to" guides recommend cutting the overflow tube at 1" below the C-L mark on the valve. When should this be done?
Conformance with anti-siphon installation requirements of the ASSE 1002 Standard
Why does the critical level (C-L) mark of a toilet fill valve have to be a minimum of 1" above the top of the overflow tube (flood plain) to be in conformance with anti-siphon installation requirements of the ASSE 1002 Standard?
What is water hammer, why is it a problem, and what can be done to eliminate it?
Water hammer is the instantaneous increase in water pressure that occurs when water flowing in a pipe stops abruptly (as with a snap action valve closing).
Why does CESCO suggest that toilet repairs should be done by licensed plumber?
Should plumber’s putty, thread sealant, grease or lubricants ever be used in the installation or repairs of toilet fill
What is the least understood and most ignored routine maintenance tasks?
Why is it important to recognize and conform to anti-siphon codes?
What is thermal expansion in residential water supply pipes, why is it a problem, and what is the solution?
Why do many leading suppliers of [plastic] fill valves disclaim responsibility/reliability from product failures?
How much water should be in the bowl after the flushing cycle is completed and the fill valve shuts off?
