Just had a the Hyrdonex X Gen system with Reverse Osmosis installed 10-10-19 in Kyle TX. The price/cost written on the credit application/contract is $125/mo for 72 months, which translates to $9,000.00, which is a total rip-off. The sales persons Hugo & Karen, unethically entered into a contract with a 90 year old women with dementia and had her 40 year old mentally challenged granddaughter, on disability, co-sign on the credit app. They installed on Friday and we had a leak Saturday, they modified the plumbing in the home. I can't state that Puronics is a dishonest company, but certainly some of their distributors are questionable. I am filing formal complaints with every agency that will accept one. We cancelled the contract within the allowed 3 days, but have not heard back from the salesperson. Their office Aqua World Systems, in Houston TX, only has a non ENglish speaking women answering the phone and can give you no assistance. These people are deceptive, unethical prey on older consumers, the two people that came out were both hispanis, so was the technician Albert, that did the installation. He did not speak any English. I called Puronics office in Livermore, CA and left a message for their sales maanger, Roy Esparza. DO NOT DO BUSINESS WITH AQUA WORLD SYSTEMS, distributor of Puroinics equipment.
