I am from the US, and was wondering if any kit works on every home toilet.
No they are not. Btw here in aus we got 2 buttons for water saving purposes.
Not even national. I have a toilet with a ceramic flush valve built into the tank and it’s almost impossible to find a flapper that’s set up for this.
No, but most replacement parts are semi universal parts that can be adjusted to fit the vast majority. However you need to know what toilet you have as each almost universal part doesn’t fit something another one will. Odds are you have a common toilet that any universal part fits - but there are toilets that are not compatible ith anything.
before doing anything though should you replace the whole thing is a question worth asking. do you prefer a round or engladed bowl; what about the height; maybe you want one without stains; or a low water use version that works? It wouldn’t cost much more to replace the whole thing with one that fits you better.
They are not all the same.
Measure the diameter of the hole at the bottom of the water holding tank. It’s the main difference between older and newer toilets in the US.
Any US toilet repair kit should list what diameter(s) it supports.
Depth of the holding tank will vary as well, but most repair kits account for this. Some kits may require using a hand saw to cut some plastic tubes to fit smaller tanks. Other kits have an extendable or collapsible tube.
Nothing new to add, but since crowd sourcing answers is more reliable when you have more of them, I figure it’s worth it.
As everyone before this said, it isn’t a perfect compatibility, so you can’t just grab any random kit and be certain it’ll be 100% right. But, there’s a decent chance it will be, or that you can improvise things enough to get it to work long enough to get the exact right bits.
Biggest problem I’ve run into over the years is flappers not making a good seal, and the pipe not fitting well. The flapper is harder to deal with, but the pipe can usually be made to work with a gasket cut to size, long enough to get a better one at convenience rather than having to run right back out.
Not exactly universal but there is wide compatibility. If it looks the same then you are probably ok, but you need the right type.
While the kits may use standardized plumbing connector, they are not all guaranteed to use the same standard sizes.
