What is a orifice on water heater?

An orifice is a small opening or hole in a water heater that allows water to flow through it. It is typically located at the bottom of the water heater tank, and it is responsible for regulating the flow of water into and out of the tank. The size of the orifice will determine how much water can flow through it, and this will affect the overall performance of the water heater.

If the orifice is too small, it will restrict the flow of water into the tank, and this can cause the water heater to overheat. If the orifice is too large, it will allow too much water to flow into the tank, and this can cause the water heater to run out of hot water quickly.

The ideal size of the orifice will vary depending on the size of the water heater tank and the demand for hot water. In general, a larger orifice is better for a larger tank or a high demand for hot water. A smaller orifice is better for a smaller tank or a low demand for hot water.

If you are experiencing problems with your water heater, it is possible that the orifice is the culprit. You can check the orifice by removing the drain plug at the bottom of the tank and looking for a small hole. If the hole is clogged or obstructed, it may need to be cleaned. You can also try replacing the orifice with a different size to see if that improves the performance of the water heater.
