    No, it's not rocket science, it's plumbing and unlike rocket science it requires a license.

      Thanks, did not even think about that for brazing. It is done that way on stainless all of the time when tig welding, we call it back purging.

          how about a SCUBA tank/regulator rig instead of N2?

          3000 psi in the tank (80cu/ft) and adjust the 1st stage for 100 psi (most regs use an IM of 90 psi). you even go with a smaller bottle like 20cu/ft BOB or a pony bottle.

          just a thought

                  the ram seems like it would be neat, but it also seems like it would only work if the clog were between the drain and the vent, with no overflow or any other point of entry for air.

                              An often overlooked "best practice" by shade tree HVAC technicians. They will soon find out ( Jan. 1, 2010) that if you cut that corner on R410, you will probably have a failed compressor soon!

                                With a water heater pump you can remove the top mounted relief valve or hot water nipple out of the hot side of the heater and push down a rubber washing machine hose and pump the tank dry.
