Factors to Consider When Getting the Best Toilet Fill Valve
1. Type of Toilet Fill Valve
This is one of the most important factors to get the type that suits you the best. Let's look at the five common types of fill valves.
a). Plunger / Piston Ballcock Fill Valve
The piston fill valve is one of the oldest valve designs in the market. These fill valves are made of cast brass that enables them to give you durable and silent performance.
A floating ball valve is attached to a pivoting lever and enables this fill valve to work alongside the flush valve. The drawback with this fill valve is that it doesn't have any anti-siphon protection.
It also doesn't meet modern plumbing standards. As a result, most toilet models and most toilet brands don't use this type anymore.
b). Diaphragm-Type Ballcock Valve
Just like our previous type, this one has also been around for years. Most of these types ate made of brass or plastic.
This type also features a large floating ballock lifted by the water in the toilet tank and closes the inlet once the water tank is full. This is to prevent the water flow from continuing.
c). Float-Cup Fill Valve
This replacement valve first made its debut in the market back in the 50s. It soon became a household name for Fluidmaster's toilet parts.
You might recognize the O-shaped cut that moves up and down with the water. Metal spring clips the cup to an actuating rod. Depending on the water level inside the tank, you can adjust the rod. This is the most common fill valve in the market.
d). Floatless Fill Valve
These types of valves use a diaphragm and a mechanism that is sensitive to water pressure. This fill valve fits easily into the toilet water tank and has an easy installation process. In addition, the small number of moving parts makes this valve durable.
However, they are not as commonly used at the float cup valve above.
We've seen that different valves are made of different materials. For example, some high-efficiency toilets often use plastic valves that won't rust even when exposed to a hard water supply.
Another advantage of plastic fill valves is that they are long-lasting. Nonetheless, the metal valves that we've seen above are high quality and will not rust over time.
However, keep an eye out to avoid choosing valves that can corrode or rust when exposed to hard water. Of course, if you don't have hard water in your toilet tanks, you don't have to worry about this.
3. Toilet Tank Design
There are low-fill tanks and classic toilet tanks. If you have a low-profile tank, ensure that you get a fill valve that suits this type of design.
Getting the wrong fill valve can mess with the water supply and will give you a bad experience. On the other hand, it may be quicker for you to get a suitable valve if you have a classic toilet tank.
A universal fill valve can work for many classic toilets but not so much for low-flow toilets. Our second and third picks are great options for your modern or classic toilet.
Frequently Asked Questions (FAQs)
1. Are all the fill valves similar?
No. As we've seen above, there are various types of valves, and they all come in different designs. So before you settle on the new valve you want, ensure that it is the correct type. A universal valve can be a good choice as it goes with various types of toilets.
2. How do you know if your toilet fill valve is bad?
A malfunctioning valve often has several characteristics, including the following.
- Running toilet
When the water is constantly running, or the flapper is leaking, it's time for a fill valve kit like our first pick above. This may mean that you have a worn-out fill valve. You can also check if your flush valve has a problem.
- Screaming or humming toilet
If you hear any annoying sound coming from the tank, it might be time to get a new fill valve or flush valve. Most toilets are easy to check, so you can easily pinpoint the root cause of the problem.
- Slow filling rate
- Toilets flush ineffectively
