Toilet repair help, is it possible to change Canister style flush to normal flapper?

The old canister is just too heavy, it broke the flush handle few times.

I'm thinking to replace this canister to a much lighter flapper, but don't know if the size of hole in the bottom will match.

The one I have is like this one in the video:

I don't think you would like the results if you did this. The canister style is the new way the eco flush works, all that water emptying fast gives it the power. Instead of going to the Big Box store I would try going to a plumbing supply house or plumbing store and see if you can find a metal handle/arm.

I have several of these at home and work and have not had this issue. I would check to make sure your water level is correct too. Maybe you have too much water thus extra weight.

I see. You mean this Canister style valve is more recently water saving style?

Recently, I also noticed the water coming from the fill valve is slow, I may need to change both the fill valve and the handle.

The handle I bought from Homedepot is made by plastic without any metail inside, cost $7 something, let me check if I can find a metal one...

A picture of the insides of your actual toilet might be helpful.

You can buy a kit to replace everything pretty economically with Kohlr parts. I bought my last one for a work toilet on Amazon.

There might be a plumbing supply house in your area that will sell to the general public and could have the parts (but be warned most of these places close by 5 or 6 pm). You'll want to figure out part numbers and things before you go to one. Last time I was looking for toilet parts, I think lowes' selection may have been better than home depot's.

You can always do a bucket flush while you wait for the parts.

Bucket flush also works well when you don't have a plunger and need one.

Fluidmaster sells a 3" flush valve kit to replace the guts. You have to remove the tank though. (which sounds like you don't want to)
Stores have metal flush handles, even walmart

There are some 3" flush valve replacements that might work and would switch you to a traditional flapper. But in doing so you might adversely effect the performance and water consumption of the toilet.

Not compatible with the OP's toilet. This one is for your standard 2" flush valve. The OP's toilet uses a 3" valve.

Most reviews and ratings by credible sources have been pretty negative towards these conversion kits and dual flush generally.

There's a black and green flush valve lowes sells that I think is 3" and is higher quality than most.

I replaced the flapper in my toilet four years ago with this one:
http://www.amazon.com/gp/product/...UTF8&psc=1

and it have been working great since 2010.

The reason I replaced the flapper was because it was leaking water and it gets annoying to hear the toilet tank gets refilled once every 5 minutes, not to mention all the wasted water. I tried replaced the flapper but it did nothing. The canister style stopper provide more pressure and the seal.

Incompatible with the OP's toilet.

If the flush valve isn't leaking, it sounds like a handle with a metal arm is by far the simplest solution. It's possible to replace the seal on the canister valve (as in the video you linked to). If you get kohler replacement parts, you may be able to swap the upper portion of the valve pretty easily (but it's hard to know if that would fix your problem). I'm not sure about this particular part/toilet, but it seems like some of these canister valves could have a hollow air chamber, if your's does and it's taking on water that could be a problem.

Any other flush valve replacement is going to require you remove the tank, and putting it back can be harder on kohler toilets (depending on age/design). Many kohler toilets use a triangular shaped gasket (under the tank) and 3 bolts which often requires finding specialty parts and are more of a pain to deal with. However, newer kohler toilets may use a metal bracket that's epoxied to the bottom of the tank and have no holes for bolts that go through the tank and is easier.

Moral of the story, newer toilets and newer kohler toilets in particular are often more difficult to replace parts on. Various design choices on many newer toilets make it harder to use "universal" replacement parts.
