I have worked as a commercial plumber.
I became very skilled in layout, fitting, & installation of multiple different piping systems.
My top trade is welding carbon steel pipe using stick.
I am also trained in demo & installation of cooling towers, pumps, water heaters, boilers, heat exchangers, air handlers, chillers, all the way down to simple check valves.
I am trained to solder, braze, & of course weld pipe.
I worked in this trade for just over a decade.
