Review on Aquasana Filter Installation Fittings Pre Filter: Enhance Your Water Filtration System with Easy Installation and Improved Performance by Greg Greiner

I bought 10,000,000 gallons or 10 years. Well filtration system with ultraviolet light. We will freeze 1 of the 2 big blue main tanks. So I buy a replacement for 800.00. They don't bother providing rebar or anything like that. The old fittings could not be removed from the defective filter. Please add the fittings when you sell the replacement filter. Since the filter was broken, I decided to open it. Just a carbon filled fiberglass tank. Looked pretty simple and not very technical. It appears that carbon accumulates until it is no longer absorbed, at which point it potentially becomes a source of pollution. I have a feeling this low tech might be overpriced and overpriced.
