The Fluidmaster 502P21 PerforMAX toilet flapper is pretty straightforward to install, mainly because it's designed to fit most 2-inch flush valves. These are pretty standard in lots of toilets, even those with high-efficiency or slightly older models. The manufacturer talks about its universal design aimed at maximizing flush efficiency while saving water, which sounds handy.
From what we've found, while it works in many cases, there can be some hiccups when it comes to specific toilet brands like TOTO or certain Kohler models.
A few folks mentioned that the fit wasn't quite right, especially if your current setup has unusual sizes. For example, it seems for some TOTO models, the flapper might be a bit too small. So, it’s definitely worth checking the measurements on your own toilet before buying one, just to be sure it’ll fit right.
Most people seem to like the Fluidmaster 502P21 for its water-saving capability and ease of installation. But if your toilet has specs that are a bit out of the ordinary, double-checking before you commit could save you some trouble.
And if things still seem a bit iffy or you have a more complicated setup, getting a plumber's opinion could be quite helpful.
