Just had a Sentinel test back reporting ph8.8, and possible aluminium corrosion (recommended <ph8.5). System contains some new radiators including aluminium.
Internet seems mixed on whether aluminium oxide is stable to ph8, 8.5, or 9.
Any thoughts on whether drain and clean is really needed?
Many thanks indeed.
