“It's a nicely made adapter but unfortunately I made a mistake with the thread size, turns out I need a US Garden Hose Thread 3/4" 11.5 TPI parallel.
For some reason spa's sold in Australia use this US thread on the drain valves and it's impossible to buy fittings for the thread. I found and irrigation company that stocked the adapter but they had closed their business two weeks before I found their site. So, off to a machine shop next week to have a fitting made.”
