So, which is the best shut-off for your washing machine and how do you choose? Well, continue reading this guide to discover some of the best and most effective washing machine shut-off valves available today!
First, here are some of the most important aspects you should consider before you settle on any shut-off valve!
What to Look For before buying shut off valve
Type of washer shut off valve
In general, washing machine shut-off valve can fall into 2 categories; automatic and manual.
As the name suggests, manual valves have to be turned off and on manually using the lever control. More notably, manual valves usually have a pretty simple and basic design. As a result, they’re quite easy to use and install and come at very affordable prices.
On the other hand, automatic shut-off valves turn on and off without human intervention when the washer is working. They feature an innovative design that mainly consists of the valve, leak sensor, and electronics. Even better, some automatic shut-off valves are so advanced that they can be controlled using common devices like tablets or smartphones.
While it’s important to consider the type of shut-off valve to install in your washing machine, both options basically do the same job. That is, regulating and controlling water flow into the washing machine and preventing water damage.
As you go through various washing machine shut-off valves, you’ll realize that they’re made of different materials. Some of these materials are; brass, plastic & stainless steel. It’s important to consider the material used in the valve you intend to buy since each has its benefits and drawbacks. Besides, the type of material used will help you to assess the quality of the shut-off valve.
For instance, stainless steel is highly resistant to corrosion. At the same time, it has an excellent ability to withstand high temperatures, making it a good option for washing machine shut-off faucets.
However, most washing machine shut-off valves are commonly crafted from brass material. Thanks to its exceptional durability, allowing you to use it for several years without any problems.
Lastly, plastic is cheap and has low thermal conductivity. Therefore, it will not overheat when exposed to hot water flowing into your washing machine.
The size of washer shut-off valves is often measured in inches. Size is another important factor to consider since it may vary from one shut-off manufacturer to another. Fortunately, you can easily determine the ideal size of the shut-off valve by checking the label on your washer.
Lastly, make sure you check the maximum pressure the shut-off valve can handle and your washer’s water pressure. If the water pressure is low, you’ll need to buy an adapter to fix this problem.
That aside, here are the best shut-off valves you can buy for your washing machine!
