update on Pennington so-called plumber/solar comp

I have reviewed this Company before but just an update: the solar geyser that was fitted on the top floor works fine , the pipes however vibrate and make an irritating noise when any tap is used. I finally had a real plumber look at the system and we found that the pressure reducing valve ( which I did paid for) was never fitted, the real plumber fitted one and the vibration of the pipes went away. Again: stay away from this rip-off artist.
