No one knows more about the kind of service and quality BioTech Water Researchers provides than our clients.  We regularly receive “Thank You” notes, letters, and emails from clients telling us how BioTech Water Researchers San Antonio has met every aspect of their water needs.

Here are just some of their comments and stories:

“Hank with Biotech Water Researchers demonstrates sincere concern for and commitment to providing the best care and service to his customers. Hank showed me his extensive portfolio that illustrates his passion for caring for his customers and our environment. The world needs more businesses and staff who demonstrate quality customer care.”

“We purchased a new home and received presentations from five different companies. At the end, we installed a water softener from BioTech Water Researchers. The presentation was long, but covered everything. The team who installed the system was great and did an outstanding job explaining operations and maintenance. Price was reasonable. My wife and I are pleased with our choice and recommend BioTech Water Researchers.”

“Very professional and quick installation. Water softener is easy to understand and maintain. Love the quality of the water since we’ve had this!”

“Reviewed by Lisa Keel”

“Hank and his team are a first class operation. Hank was kind enough to meet with us in the evening when my wife and I were both off of work to discuss the options for a water softener for our house. There was no pressure and all of our questions and concerns were fully answered to both of our satisfaction. When the day for the install came his team gave us a call when they were about 15-20 minutes away and when they arrived they went right to work. Everyone was very professional and finished the install about an hour quicker than what Hank told us it would take. The installed equipment and piping looks very clean and professional. You can tell his install team takes great pride in their work. We went with the full house softener with chlorine filter and reverse osmosis drinking water system and could not be happier. If you are in the market for a softener I would highly recommend hank and his team.”

I just had my whole house filtration system and RO installed by Biotech. What a difference this has made for me. Soft, filtered water is amazing in what improvement it’s made to my appliances, laundry and health. My towels are bright, fluffy and soft like they were the day I bought them. My local water was very high in Chlorine. So much so, that you could maintain a swimming pool with no added chemicals. That is disturbing to me. My water tastes amazing now. This is actually my second system from Biotech. I got my first system 15 years. I’ve since moved and liked the system and company so much, I’ve had a new one set up in my new home. Every thing was done professionally and with focus on detail. Fittings were done with copper fittings and pipes were all wrapped and insulated. My home and yard were left basically unchanged after an extensive installation. Thank you Hank and crew.

Reached out after finding I had a home made “internet” water system installed by the previous owner that was doing nothing. Fair estimate and Fast install! completely honest and informative. Recommend to anyone in need of a water softening system.

All work was done on time, within budget and in a professional manner. Thanks BioTech for a job well done.

I just wanted to pass on my sincere appreciation for how well you and BioTech care for your customers. Our water softening system is at the 5-year mark and it has been perfect. The BioTech staff has always been helpful answering questions and making sure we understood the system and how to care for it.
While I was deployed in Afghanistan, your team even came out and helped replace the large filter for my wife. Today, you dropped everything and drove across town to help me with a problem and you didn’t leave until it was fixed, even though it was user error, and you didn’t even charge us.

BioTech delivers honest, sincere, service to the customer and the community. I have recommended BioTech to all my friends and family and I will continue doing so for many years. Thank you again.

The presentation about what would be done while installing a water softener was excellent.

Very pleasant company to do business with. Our water softener works great and we finally have water that is drinkable from a faucet in our kitchen. No more lugging around water jugs from the store. Our high dollar dishwasher actually cleans like it was supposed to, spotless dishes finally. We have already noticed a huge difference in how clean our faucets and shower stay. Our clothes even feel different on our bodies. Thanks.

You were a pleasure to work with and so was your crew. They came out and worked in the pouring rain and didn’t leave a mess.  Thanks Hank!

The owner himself came out for our initial visit. I can say unequivocally say I learned more about hard water and appropriate water softeners than I thought was possible. His crew were out exactly on time, extremely professional and completed the work on time with impeccable results both mechanically but also aesthetically, as my input was asked before a single piece was installed. We frequently get emails thanking us and wishing us well, and our softener was installed in July 2017. I have always been a fan of hiring local businesses, but this company is by far one the most professional and helpful organizations I have ever had the pleasure of dealing with. We plan to continue to stay with this company for intermittent tune-ups, filters and future advice. Hands down a PERFECT 10 out of 10!


Recently received a new water softener system in a 13 year old home that has never had a water softener. The BioTech install team was very courteous, hard working and thorough including successfully trenching under my concrete driveway in cold rainy weather. So far the product is working well and I am hopeful that the hard water build up in my plumbing will slowly disappear. I am glad that I added on the under sink reverse osmosis water system to my kitchen sink for drinking and cooking water. Thank you Hank for the great service.

The owner of the company, personally came out to our home. He is extremely knowledgeable in all facets of water filtration for the home. After buying my house I interviewed 5 water companies and found that no one knew their business as well as Hank knew his. He was able to provide us with an accurate price for exactly what we needed. There was no gimmicks or strong arm tactics. They were extremely professional. When the crew arrived they were done before we knew it. After 12 years of owning our equipment, I have never had a single need for a service call, ever. On my next house I will definitely call Hank to do work on it as well.

I thoroughly researched water softeners and after choosing BioTech Water Researchers for my home water softening and reverse osmosis treatment. I have no regrets as I have had the system running effectively and had clean, soft water for over 18 years!

First of all, you are AMAZINGLY kind and knowledgeable about your company! I want to thank you so very much for taking your time to speak with me about my water issues in my home. I had second thoughts about the RO water I was going to rent through the popular water company that came to my house a day before. THANK YOU! Now, I don’t need to worry about renting a reverse osmosis water filter. I OWN one, thanks to you! I appreciate your kindness, ability to listen to what I wanted, not what YOU wanted for me. Even after 5pm, you came over to my house to make sure it could be connected, showed me facts and statistics about water (down to the smallest molecule), and made an appt. after I felt comfortable and confident in you and your amazing business and background work/research. You are a hard worker and it shows!! The installers were at my house ready to install. They were knowledgeable about the system and very kind, as well. Keep up the EXCELLENT work, and EXCELLENT workers!! I will continue to tell everyone about your business. AFFORDABLE PRICES, kindness, and much needed AMERICAN patriotism. You sold me on that, right there!! MADE IN AMERICA!!

I originally wanted this for my St. Bernard, who is extremely picky about water, and here I am, sitting at my desk while my students are at lunch, drinking your wonderful RO water!!

Thank you for this wonderful miracle!
