Why do I have to manually top up my header tank?

While we acknowledge that the manual fill of the header tank can be inconvenient for some homeowners, this feature has important safety implications since it significantly reduces the potential for damage to the property and potential injury to residents in apartments below.

You can install a ball cock with automatic topping up on the system. However, in the event of a leak or ball valve failure, systems which automatically fill themselves up will continue to do so indefinitely until the problem is resolved. Such issues have been responsible for causing massive damage to property and the implications of leaks within apartment developments can be extremely serious.

By contrast, the inability of the PulsaCoil unit to top itself up means that in the event of a significant leak, the only water that can be lost is the water held in the cylinder at that time.
