If you are thinking about asking this company out, don't do it. They will lie and tell you that this system will get your water clear and your toilets will no longer have brown stains. But beyond all of that, the customer service is terrible. Trying to get your system serviced is a complete nightmare. They reschedule so much they hope you will give up trying. I would give it up if I could service the system myself.
Recommendation: Try a different avenue, this isn't the way
