CESCO BRASS has maintained a Toll Free HOT LINE for many years.

Our know-how is based on countless telephone conversations and field contacts involving the products that CESCO has designed, manufactured, and sold to the trade for a century.

Our primary business is toilet tank fixtures, fittings, and trim -- and always has been. CESCO's "new generation anti-siphon fill valves" (ballcocks) were developed
in response to customers' suggestions, positive feedback, complaints, and our thorough testing and evaluation of malfunctioning returned goods.

We carefully executed the design, development, and field testing of all new product prototypes to ensure that new products would: Add performance benefits under the most demanding conditions Reduce and simplify maintenance requirements Improve reliability and extend life service Protect pipes from damage Conform to all code requirements This is not intended to be a comprehensive or authoritative "how-to" manual for diagnosing and fixing malfunctioning gravity flow toilets.

We are still learning from some of the best service-oriented plumbers who deal every day with the complex problems of plumbing systems. Based on our experience, Common Troubleshooting Steps and some Frequently Asked Questions are listed below that relate to design, operating principles, installation, and maintenance factors. Since much of our knowledge derives from past feedback from professional plumbers and other plumbing maintenance personnel, we encourage your e-mail response, phone calls, or letters. We will listen.

With toilets accounting for as much as half of all residential water consumption, it is somewhat amazing that these frequently used, inherently automatic devices function so reliably (with limited attention) every day in a wide range of conditions.

Internal or external leakage is not always easy to detect and all malfunctions should be fixed without delay to avoid excessive water usage, to prevent potential damage to supply piping systems & building structures, to maintain sanitary conditions, and to eliminate nuisance noises.

In simple terms, it does not pay to ignore your toilet, yet people often tolerate a malfunctioning toilet until leaks and noises can no longer be ignored. Wait too long and it may be necessary to call a plumber, a carpenter, and a physician.

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?
