Steam generator pressure relief valve


All Helo steam generators have a pressure relief valve. This is a safety precaution – if for some reason the steam pipe were to get completely blocked, with the steam generator on, there would be a pressure build up in the steam generator tank, which would be able to escape from the pressure relief valve.

Although in domestic installations it is very unlikely that the pressure relief valve will ever operate, a copper pipe should be run from the valve to a drain where it can discharge safely.
