Wouldn't think there was enough clearance for the float to work.
Float valve coupled with the drain valve is awesome...
...video proves that, but wondered why the wound quit, wanted to hear the valve shut off.
Also appreciate failure of heater documentation, great idea to put it in a spoiler.
This is experiment not done yet, so I have hesitated to rate/review,
but so far the testing protocol and the documentation of the results it is excellent.
I have no doubt that it will be continue to be so.
Thanks for your review.
