After nearly two weeks of use the pressure switch has failed. Tried to claim to get replacement part but couldn't upload the videos on their messaging service or through email.
Apart from being a little noisy you do get a pretty decent flow and pressure from the unit that can handle a decent shower head( if you remove the flow restrictor in the shower head) I'm currently bypassing the pressure switch and getting a separate pressure switch to run the unit.
Things that need improvement, 1 pressure switch, 2 quite the motor a little, 3 improve the video upload on your messaging system so you can accept at least a 30 sec video clip without the use of a third party platform
