What type of valve is best for water heater drain? At some point, every water heater will need to be drained. This is usually due to sediment buildup, which can be avoided with annual maintenance. While most water heaters come with a factory-installed valve, it’s a good idea to know how to choose the right valve in case you ever need to replace it. Here are some things to keep in mind when choosing a valve for your water heater drain.
The first thing you need to know is the size of your water heater. This will determine the size of the valve you need. The most common sizes are 3/4-inch and 1-inch, but there are other sizes available as well. Once you know the size, you need to decide which type of valve you want. The most common types are ball valves and gate valves.
Ball valves are closure devices that use a ball with a hole drilled through the center of it. When the hole is in line with the two ports, water can flow through; when it’s not, water is blocked. Ball valves are easy to operate and don’t require much maintenance, making them a popular choice for many people.
Gate valves act as blockers or regulators for fluid flow. They get their name from their similarity to gates—when the handle is in line with the pipe, fluid can flow through; when it’s perpendicular, fluid is blocked. One advantage of gate valves is that they can be regulated so that only partial flow is allowed through, which isn’t possible with ball valves. However, they’re also more likely to get stuck in the closed position because of corrosion or sediment buildup.
Conclusion:
When choosing a valve for your water heater drain, there are several things you need to keep in mind, such as size and type. Ball valves and gate valves are the two most common types of valves used for water heaters, but there are other options available as well. Ultimately, the best type of valve for your water heater drain depends on your specific needs and preferences.
