Just out of curiosity, but what did you do to make those screw in fittings leak proof?I am asking because shortly I might need to do something similar.Vince
Hi CruebyShe is looking great Still following along down under.Pete
Thought I'd reply to the question about filling the boiler via the blowdown valve. On a lot of the 1.5" models I've seen the blowdown is threaded to take an adapter that allows a standard garden hole to be screwed on. Typically this adapter has a 1/4-NPT male thread and can be found at most hardware stores. It would probably be too large a thread to do directly to the blowdown at your scale, but a reducing bushing could work.
