I have been wanting to try this step down regulator from my booster pump on something else beside the booster pump for a long time. Today I finally found an alternative use. Instead of hauling out my compressor used for my nail guns, I brought out one of my CF tanks and the 90 psi step down regulator to blow out water out of the water lines in the travel trailer. After a few minutes, all the water was blown out of the lines, and I can turn off the LP heater.
