Core Power Plays

The specs and strengths that make it shine.
Discussion about the general need for toilet repairs
6 months in and no regrets! It's been exactly what I wanted.

Hidden Hero Hacks

Unexpected tricks and side‑door uses you’ll love.
Discussion about the practicality of bidet attachments vs. full seats
This gem of an accessory checks off all essentials: quality, durability, comfort and most importantly, hygiene; it's been a game-changer in restroom convenience for me.
Maybe an unpopular opinion but I think the total bidet seats are not necessary.

Buyer’s Cheat Sheet

What to check before you click ‘Add to Cart.’
Specific parts may not be universally compatible
No. The flapper. Isn’t a universal one.
There are two very similar, but incompatible Kohler flappers that look like what OP has.
No that's a kohler toilet and a specific flapper.
Replacing the entire toilet might be a better option
that thing is a pile of junk filled with bacteria and calcification
At some point you gotta top putting band-aids on this.
Buying Fluidmaster in bulk can be cost-effective
how much that purchase nets us, its unreal. Real money makers.

Cautionary Callouts

Know the pitfalls before they catch you off guard.
Korky valves are often criticized
Korky is the absolute worst quality.
Will never choose a corky.
Universal Fluidmaster parts can be affected by cleaning tablets
The problem is that they also dissolve the plastic and rubber of the internals.
It works like a charm.
Hard water can cause flush valve issues
The flush valve gets a hard water lime build up, so try replacing this first if the flapper doesn't work.
General praise for Toto as a brand
Toto is the best. Both are fabulous.
Is this a joke? I do actually have Toto washlet though.
Discussion about the variability of Fluidmaster quality from different sources
I’ve had bad luck with the ones from box stores, never had much for issues with the pro 45B.
Discussion on the longevity of Korky parts
I'm just surprised that I had better luck with the stock - contractor grade parts.
