What to do if pressure reading on AquaScan is lower or higher than expected?

Ensure all outlets are closed and that there are no leaks in the pipework before the testing point. If the static pressure falls and the isolation valve on AquaScan is closed it may indicate a drop in pressure from the pipework or an outlet before the unit. The peak measurement will show the initial reading.

Check that there are no leaks on the connection between AquaScan and the outlet/system/pipework. Pressure will naturally fluctuate, particularly in mains-fed systems.
