I used a hacksaw and a hammer to remove the plastic from the brass threaded bottom. Next I used my angle grinder to remove one end of the threads and
a little more so a copper coupling will slide on. Using my plumbers torch I sweat on the coupling, a length of 3/4" copper, and a hose bib at the
end. It makes adding a gage and gas quick and easy. Water is already hooked up at the other end.
