"Although this company tends not to be "warm and fuzzy", they provided an honest assessment of my home's needs, were professional, and offered the best price, by far, compared to other water treatment businesses. I interviewed four companies and, as of right now, I'm glad I selected Aquascience. The installation technicians were professional and efficient. So far, I have only good things to say about the company."

"Excellent experience during a bad situation. We discovered our well head was leaking on a Sunday afternoon. Joe, the owner, came out the same day to assess the problem and told us how to avoid burning out the water pump. Joe and his crew came out the next day. Repaired the problem, with no surprises. He took the time to explain what was wrong and what he needed to do. Very professional, courteous, and knowledgeable. Everyone at Old Faithful Pump Co is friendly and it was pleasure doing business with them. We recommend Old Faithful Pump Company to everyone."

"The service, installation and workmanship was excellent. High quality system was installed for a better water system. Filters installed on kitchen siink RO improved the taste of the drinking water. The RO was in excellent condition and installed over 15 years ago by owner's grandfather! Owner knows the whole system well. Drop cloth was used on the carpet. Workmen were courteous and office staff were helpful with getting the appt set up."

"Moved to a new house in a new town right away there was trouble with our water. The appliances had residue and the tap water was cloudy. Had a water softener and iron breaker at the old place so was familiar with water treatments but wanted a new no salt solution to fix the current problem. At the first visit Bill took water samples and identified the issues. He recommended a treatment system void of salt that is working wonders. The refreshing of the potassium bags is no big deal that I donâ t even need my husband to do it. Now our appliances work and look better. And without hesitation our family drinks straight from the tap! That was something unimaginable before PuraSoft."
