Frequently Asked Questions
Q: What size are these water pressure diaphragms and which water heaters are they compatible with?
A: These diaphragms measure 50mm in an oval shape with an inclined hole. They are designed for gas water heater pressure valve assemblies, including MBJ5E models and other compatible gas water heaters that use the same diaphragm specification. Always verify your model's diaphragm size before purchasing.
Q: Are these diaphragms difficult to install?
A: Not at all. These 50mm silicone diaphragms feature a simple drop-in replacement design. No specialist tools are needed — simply access the water pressure valve assembly on your gas water heater, remove the worn diaphragm, and fit the new one. The process does not require disturbing other parts of the water heater.
Q: Why should I replace my water heater's pressure diaphragm?
A: A worn or damaged water pressure diaphragm can cause irregular water temperature, poor flow, or heater ignition issues. Replacing it with a quality silicone diaphragm restores accurate pressure sensing, improves heating efficiency, and helps extend the service life of your gas water heater.
