DIY simple toilet leak detection and repair of a dual-flush system

This video shows how to detect toilet leaks on typical American style home toilets and in this case I am repairing a dual-flush flapper system. The dual flush can save you lots of money in the long run as it uses less water to flush for #1 and gives a full flush for #2.
I believe the main reason my system needed repair was due to chlorine tablets used in the water closet. Chlorine tablets will attack many things in addition to the funk you're trying to prevent in your toilet bowl -- in my case it caused a zip tie inside the water closet to become weak and break. It also started to eat away at the rubber ring used to keep the flapper valve assembly in place. Don't use chlorine tablets!
Spoiler alert: I didn't need to replace any parts to make this repair; I merely added a hose clamp to help keep the dual-flush assembly securely sealed to the opening in the water closet where a traditional flapper ball normally be found.
I didn't have any issues with the fill valve system but was pleased to learn it has some user-serviceable parts. All I did was clean these parts and inspect for any issues. The fill valve is a Korky anti-siphon design and Korky has a very useful KZbin video describing how to clean and service this valve at • Korky QuietFILL Toilet...
The dual flush system I use on my toilet is made by MJSI Inc called the HydroRight and their product web site is at www.goMJSI.com/

I think this fixed my problem! Might use a stainless steel zip tie next time.

Putting the small refill hose into the container could mask an existing problem. If the refill hose is too long, and/or the end of that hose is not supported above the water line, it can siphon water out of the tank and drizzle it into the overflow tube. If that is happening, pulling the hose up and putting the end into a container may convince you that's not the source of the problem, when it might still be.the problem. Always make sure the end of that hose is above the tank water level.

Good stuff John. Your diagnostic techniques with the dye and food container will go into my "bag of tricks" for future reference.

+Albert Straub thanks! The red food dye worked for me and was easy to see. I came up with the food container trick on my own :-)

You saved me from making a mistake. I, too had a "Phantom flush"; it turned out that I too had a plastic tie that had broken off.

[@JohnsDIYPlayground]

Awesome! Happy to hear you got it fixed, and nearly free! :-)

What is the size of the rubber seal that needs to be replaced?

[@graemebr]

Really, anything that will keep the device firmly fixed down on the outlet. The metal hose clamp is a great idea. The rubber is just to fill in for a size difference. Lots of luck. !
