The outdoor tap for the front yard of our house has an outer diameter of 1-1/4" inches, so it is useless for attaching a garden hose. A standard tap is more like 1" in diameter.
My question is: Why? And is there anything I can do about it, short of installing a new tap? Anybody seen this before?
It looks like an adapter (a ring with a normal hose thread inside and larger thread outside) may have been screwed on to create the wider outer diameter. But if that's the case I've been unsuccessful in removing it with the tools I have. A plumber that looked at it speculated that it had been modified for something like a backflow preventer.
I've added a picture below.
