Have just had a new Bradford White water heater installed for house. The very typical thing; 40 gal, upright cylinder. Gas fired.
Question: The drain valve on the very bottom is of a kind I've never seen before.
Rather than the what I had assumed is "typical," this one has the treaded fitting for a hose, but the top is a rather small, threaded, stem with a slot in it for apparently a screwdriver.
No typical stem with a handle on the top, like "before".
What is this new kind of valve drain valve ?
How does one use it ? Mutli turn, or,...?
Why did they go to this type; pros and cons of ?
As always, much thanks, Bob
