Thanks for all the input, we ended up waiting for the valves, which by the way do leak themselves somewhat, so last tip was correct in that. Not too much for what we are doing though, so full steam ahead. Thanks to all.
Had lots of tube repairs done so time to do a hydro, only isue is boiler stop valves were taken for repair and not returned yet. Now return is delayed another week, but need to hydro to release contractors and continue with re-gunnite and re-insulation. HELP! Is there any way to use some sort...
