Replaced Your Toilets Flapper and It's Still Running?
If you have a toilet that continues to keep running even after you've replaced its flush valve flapper try this simple fix.
There are several different things that can cause your toilet to keep running so lets check those first.
1- Worn flush valve flapper. These can go bad after years of service and requiring replacement. NOTE: Never place any cleaning tablets in the water tank of your toilet. These can corrode the flush valve and its components causing your toilet not to function properly.
2- Clean the surface area where the flapper rests on the flush valve. This area can build up with calcium over time causing the toilet to run.
3- The water tanks fill valve is adjusted too high. If the toilets water tank fill valve is adjusted to fill the toilet too high, water will enter the overflow tube, causing the toilet to run. Make sure the filled water level is no higher than a quarter of a inch (1/4") from the top of the overflow tube. Do this by lower the float in the toilets water tank.
If you done the above items and your toilet is still running and you don't wish to replace the complete flush valve assembly (which requires removing the the water tank on a two piece toilet) try this simple fix instead.
You will need to purchase the pictured Universal 2" Flush Valve Flapper Repair Kit. (NOTE: If your toilet has a 3" flush valve you will need to purchase a repair kit for that size instead.) You will need a small piece of wet/dry sand paper, 180 to 400 grit will do. A sponge and a clean/dry towel.
Important: Let adhesive dry at least 15 minutes before filling water tank! I recommend a half hour or longer.
After you have installed the new flapper unit be sure to adjust the pull chain to the handle so that flapper opens and closes all the way. This may take a few times to get it just right. You don't need water in the tank to make these adjustments.
And there you have it! I've done this particular repair several times myself with great success. The alternative is to remove the toilets water tank and replace the entire flush valve assembly (which if you do, I recommend you replace the water fill valve as well) or replace the entire toilet. Hope you find this helpful and thanks for reading.
