Ball valve or gate valve for water heater. Totally agree a ball valve is preferred. Replacing a broken gate valve on the cold water feed to the hot water tank with a ball valve supposed to be more reliable. I just don t like when someone comes in and starts saying it is code to have a ball valve versus a gate vale and they won t install the water heater unless you write a check on the spot for an additional 85 due to the code requirements for a ball valve. The gate valve is also part of the rotary family as the wheel or actuator needs to be rotated for the wedge or disc to open.

For its closing position the gate moves downwards and between two seats located on the upper portion of the disc as well as at its bottom as shown in the image above. A ball valve like the one shown above which utilizes a center ball with a round tunnel cut out of its center and a gate valve which uses a plate that descends across the pipe cross section to close it are two types of full open valves. Depending on the size a gate valve costs around 5 and a ball valve is usually under 10. I don t want a gate valve but do i have an existing gate valve installed.
