> He also offers a steam hose with valve to steam clean the engine after a run.
Roundhouse also offers a vacuum tap valve that screws into the backhead water-level bush. It's not a check valve, but a little globe valve with a handle on it, so you can blow (if there's pressure in the boiler) or suck (if the boiler is cooling off) depending on when you open the valve. It would work for a steam lance, too. regards, -vance- Vance Bass Albuquerque, New Mexico, USA Small-scale live steam resources: http://www.nmia.com/~vrbass
