I need to replace a temperature sensor in my condenser boiler. It looks easy enough but I would like a little help and advice.
It looks like I have to screw the sensor into the pipe (inside the boiler), because I see a little thread on the new one I just purchased. Do I have to part drain any water that's in the pipe where the current faulty sensor is situated? I don't want to just unscrew it because obviously that would leave a little hole resulting in water leaking.
I'm not sure if it's just a small amount of water that needs draining in order to replace one of these? These sensors are so tiny it looks like just a couple of quick turns and it's fully home. Just then need to attach the two wires onto the sensor pins.
Thanks.
