Editor's Notes

September 06, 2020:

The most important thing to remember choosing a toilet fill valve, is that you must make sure it's compatible with your specific toilet. Use the model number on your toilet to look up what kinds of valves it accepts, and you can start from there. Keep in mind that even the "universal" options are usually only referring to a specific brand of toilet, not all toilets on the market.

If you have an older toilet that is using an outdated fill valve -- even if it's still working -- you probably want to replace it since it probably isn't meeting current plumbing standards. One of the most common outdated styles is the ballcock-style valve. These are easy to spot due to their signature large floating ball, connected to the rest of the valve with a thin stem.

Installing your new fill valve is a relatively simple process, and can usually be done in a few minutes. The AmazonBasics AB-T105 and Next by Danco HC660 are specifically designed to be easy to install. That being said, if you're unclear on the instructions, or uncomfortable installing it yourself, go ahead and hire a professional. A plumber's fee may increase your budget, but accidentally damaging your toilet will be much more expensive.

If you're ready to replace your toilet as well, or if you're remodeling your bathroom, consider this collection of toilet options. You may be surprised at the innovation and variety on the market today. If you're feeling adventurous, one of these bidet toilet seats could be a wise addition.
