worry more about type of valve, rather than a
couple elbows.

I would rather have a straight flow if possible.

What are you doing that the single-digit-% reduction
in flow from a few curves in the hose is THAT critical?
You would need to be running hundreds of feet of hose
before you'd start noticing any reduction in pressure/
flow due to losses from the hose not being perfectly
straight.

In fact, the losses in the TEE are more significant
than anything caused by the hose.


yes, a ball valve with a 3/4" NPT to GHT adapter is the ideal solution -
as it'll last longer than the washer in a boiler drain as well.

However, if you use one, I would get a brass GHT cap for the outlet,
preferably on a chain if you can find one, to cap off the opening when
not in use. All it takes is a misplaced elbow to take a quarter turn
ball valve from shut to WFO.
