How large is the triangle screw for the water heater's water leakage protector?
If the emergency and can not buy, can use a grinding wheel or stone, but the best in the screw with grinding, grinding and comparison, to just can open on the line. Usually within 20 minutes.
The meaning of the internal triangle screw is "do not move the non professional". The basic internal triangle screws are 2 and the smallest part is 2.3. This kind of screwdriver is very rare, so it's troublesome to buy. I usually use the waste cross head screwdriver to process it.
