hopmanns Posted August 4, 2009 Report Share Posted August 4, 2009 We are very interested in your product and have a quick question for you. We are wanting to use your tank sealer to seal the inside of small water heater tanks to inhibit any rust. The tanks will not be used to heat water but will be used as a charge tank to fill solar water heating loops with distilled water and a 40-60% food grade propylene glycol solution. Before filling the system we will use the charge tank to flush the solar loop with a 2% trisodium phosphate solution (TSP found at Loweâ€™s for cleaning bricks etc.). Our question is will your tank sealer work with the above mentioned solutions of: propylene glycol and trisodium phosphate? The tanks would be used only for a couple of hours and flushed with water and stored. Quote Link to comment Share on other sites More sharing options...
