The process for selecting the right filtration system when all you have is rainwater on your property can be a bit confusing for those ‘not in the know’ and during my hours/days of online research, many companies seemed to advise systems that appeared to be more than we needed, until I found Tru Water. They provided easy-to-understand, basic but important specifications on all their models so I could narrow it down to a couple that seemed to be the right fit, and then I emailed them and my queries were promptly responded to by knowledgeable staff.
