Winkler, Manitoba Canada
I converted a water based fire extinguisher for topping off floor heat systems. I added a fitting at the bottom to connect the fill hose and two fittings on the side for a site glass. Fill the extinguisher with propylene glycol and water and pressurize to whatever you want in the sytem.
