Aqua Science Saved the Day for me!!! They came through in an emergency. I knew my water heater was going out so I had contracted with Aqua Science to have it replaced in two weeks. But suddenly at 3 pm last Friday afternoon a big leak started. Aqua Science responded quickly by moving up my installation immediately, at no extra charge. Their hard-working employee--Constantin--worked until 7:30 pm on a Friday night putting in the new water heater in a difficult tight spot in the heat...making sure the job was down right. Great job! I am very happy with my RO system, softener and roof-top pool solar systems from Aqua Science all of which I bid out competitively.
