We had our gas company come and or utility room for gas leaks and recommended that I have the gas regulator replaced. I matched up the numbers and ordered it and would like to replace it. Is there anything I should consider before doing it? The unit is a Maxitrol 325-3 and the replacement is a Maxitrol 325-3L
Just use usual common sense, you know the properties of natural gas. Always use 2 tools when loosening or tightening fittings or connections. Do not re-use any lines that have a flare type end. Try to keep adapters like reducers or gender-changers to a minimum.
