Darryl Hughes from Aqua Filter installed my water filter into my house nearly 19 years ago. He has always provided a professional service, excellent advice and has serviced my filter every year. I do not have to concern myself about when it is due as Sherryl gives me a call and makes the appointment. Darryl has always been punctual with appointments which to me is very important. I am aware that the filter that he has been using is a very fine one, around 0.5 microns so I am happy that my water is of very high quality. Thank you.
