WHY YOU DON’T WANT TO BUY JUST ANY FLAPPER!
Just imagine this! You wake up on a Saturday morning to the sound of something that ain’t your alarm clock. You hear an unusual noise coming from your master bath. Upon further inspection, you discover your toilet is turning on and off every couple of minutes. Now what would cause that? You didn’t notice the toilet doing that before you went to bed last night. You realize that by letting this go on without fixing the problem, a lot of water and therefore money is “going down the drain”. There are a couple of things you can do immediately that will help eliminate potential problems that could plague the proper function of your water closet. NOTE: The following instructions are not for Pressure Assisted Toilets.
Check “Under the Hood”
Yes, lift the lid off of the “Throne” and make the following observations!
1. Look inside the tank and try to determine why the toilet is turning on and why it then turns off continuously. When you look at the valve on the left back corner of the tank (known as a “
Ballcock” or “
Fill Valve”) you will see that it is turning on for a short time and then shutting off for a period of time. This phenomenon is called “cycling” and caused by the tank losing water. Now let’s assume you have a
Trip Lever (Flush Lever) mounted on the front or either side of your toilet tank. Look at the “Trip lever” rod and its connection to the flapper valve in the center of the tank (Flush Valve). This connection can be made of stainless steel chain, a vinyl strap, or in rare cases, a string connector. Is the chain or strap not permitting the flapper to seat properly onto the Flush Valve seat? Is the links of the chain so tight or twisted so that the flapper is pulled to the side or off center? All linkages should be loose enough to allow the flapper to drop freely onto the flush valve base.
2. If everything checks out in #1 above then the next thing to check that’s quick, free, and easy is a flapper leak test. Have your kids just finished coloring eggs for Easter? Those little colored pills dissolved in vinegar and water make for good flapper testing. Put a cup of that solution in the tank and then “hide & watch”. Or is you wife into cake decorating? If so, there a good chance she has some food coloring bottles in the cupboard. Try putting several drops of blue or red into the tank. Again “hide & watch”. If that flapper ain’t working properly, you’re going to have a toilet bowl full of colored water very soon.
There goes your 9:00 Tee Time. Your day off just became your “OFF DAY”
So what is the next step? How do you resolve this dilemma without spending a lot of time and money? Well, let’s try shutting off the water supply to the fill valve and see what we can learn about that flapper.
Maybe a little “Flapper History” is in order.
Over the past few decades the sanitary ware industry became active in national water saving efforts and the 5 gallon and 3.5 gallon toilets were phased out and 1.6 gallon (6 liter) water closets became the new industry standard. Water quality, product warranties, improvements in plastics and elastomers all had become important parts of the 1.6 gallon transition. Coast was on the forefront in assisting domestic & foreign water closet manufacturers with material improvements and early closure flappers. These improvements included the material composition of the flush valve flapper.
MATERIAL TESTS ELIMINATED MANY ELASTOMERS FROM CONSIDERATION AS FLAPPER MATERIAL
Potential flapper materials were subjected to various bowl cleaners in our lab as well as tests done at certain water company labs in an effort to eliminate water loss caused by “leaking” flush valve flappers.
HOWEVER..
The UHMW (Coast Blue) Flapper was the successful result of tests of various elastomer materials. After completion of “leak tests” by Coast’s lab, two city water labs confirmed the integrity of the “Ultra Blue flapper”. The flapper was then listed with The International Association of Plumbing and Mechanical Officials (IAPMO) as an integral part of the “Certain Flush” valve.
Drought conditions affect, water districts need to conserve water, and some agencies set forth water closet rebate programs to help reduce consumption. The Coast blue flapper was used in those rebate programs.
The UHMW material greatly improved the reliability of the Coast brand over vinyl materials that were used in prior years. Acceptance by the sanitary ware industry, and plumbers in general resulted in many companies converting all specifications to the:
