Quietest Toilet Fill Valves of 2020
Is your toilet leaky, constantly running, or too noisy to flush at night without waking up the entire house? If so, it’s probably time to chip in for a replacement valve. Though it’s not the most exciting purchase, a durable refill valve can cut down on water bills while silently refilling the tank without any hassle.
To put it simply, a toilet valve is found inside the water reservoir of your toilet. It is meant to get your toilet to refill to the proper level after flushing.
How to Choose the Best Toilet Fill Valve
Thankfully, there are many distinct, yet competent brands of toilet refill valves that are durable, easy to install, and extremely reliable even after years of daily flushes. Modern plumbing is truly a miracle, isn’t it? Don’t quote me on it, but there’s a good reason why most sociologists say that good plumbing has saved more lives than decades of medical advancements.
Before you go out and buy any refill valve, you should know that there are different models optimized for specific brands of toilets. Choosing the wrong valve will result in slow and noisy refills, in addition to raising your monthly expenses.
Depending on the make and model of your toilet, you may be better suited for a specific type of valve over other types.
In general, you should always opt to buy a replacement piece from the manufacturer of your toilet. Though universal valves are handy, customers often complain that they are trickier to install correctly and may degrade after only a few years.
If you aren’t sure of the model of your toilet, make sure to look at the valve’s manufacturer specifications to see if it will align with the type of toilet that you own. Common code numbers include “400A” or a series of letters and numbers printed on the side of the refill valve. Typically, adjustable toilet valves that lengthen from a range of 7 inches to 14 inches will fit almost any toilet make and model.
