Hi all, First post so please be gentle. I am cautiously preparing to move from sales and marketing into my own cleaning business. No real first hand experience but I have a desire to be my own boss and offer the very best service alongside my marketing experience so I am hoping to make a real go of it. I have got my head around the pressure washer and gutter cleaning aspects but am stuck on the pure water system. Do I purchase a DIY system or buy the proprietary system from brodex / ionicsystems / pure freedom. No problem with the DIY aspect by I am concerned about the end result and quality of the water. Is the additional cost of buying a full working system going to be worth it or does a DIY system give you just the same quality water? I live in a hard water area so RO is a must. Any help or advice is most gratefully received and apologies for the war and peace length of the post.
