Got the Qmaster today, but the fan was damaged in shipping.
And another thing I noticed, I ordered it with the pipe thread adapter, was told it was 1" pipe, but it's only 3/4" pipe. I bought a 1" pipe nipple and ball valve, no problem, I can still use it, but I'll have to buy a 3/4" to 1" pipe bushing now.
In the US, Pipe is measured ID (inside diameter), tubing is measured OD (outside diameter).
There are so many types of pipe, tubing and hoses, it's can be confusing.
