Installation: FAQs

What level of backflow risk are the fluids in a primary heating circuit?

The risk is dependent upon the fluid, the dose used and concentration within the system. The volume of fluids and operating pressures will also be considered when assessing the suitability of the backflow protection device or arrangement to be installed.

Please note the final decision rests with the local water undertaker.
