Would water flow through a 1 mm hole ?? How small a hole can you get away with if you just want to make sure the stat bulb gets hot water QUICKLY around it so that it opens at the correct temperature.---

Oh yes, water will flow through 1mm hole with ease. How much how fast
depends on the pressure in the system. Good point about possible air locks ... Except the air can pass through the hole and the water can rise to the hole if there is pressure behind it. But still a good thought to put the hole low to make it easier to flow.
