Do I have to use the GB162 pump group or can I fit my own pump on the system?
Although we advise the use of the pump group with the GB162 it is only a recommendation and not a requirement.
It is important to note that when using a third party pump it must not exceed a flow rate of 5m³/hr, and the power consumption is no greater than 200 watts as this is the maximum capacity of the GB162.
