Hiblow recommends that you replace the diaphragms every 5 years, or when there is reduced performance or they show signs of wear. This can significantly prolong the life of the pump. You should always replace both diaphragms at the same time.

Why has the small safety screw snapped?

The safety screw (pin) is a safety device. The screw is designed to break if the diaphragms fail. We highly recommend that you DO NOT just replace the pin or try to repair the pin. This will only do more damage to the pump. You need to replace the diaphragms along with the safety screw.

How often should a Hiblow filter be changed?

What is the difference between the diaphragm and the chamber block on a Hiblow Air Pump?

The chamber block is the complete chamber that includes the diaphragms and valves. The valves get clogged when the diaphragms fatigue or fail. Many people choose the chamber block rather than just the diaphragms as it is much easier and straight forward to replace. The chamber block kit also includes the replacement safety screw.
