Thank you very much for your valuable advice guys. Stephane I went to Revy tonight to see what I can get there to build similar gizmo you suggested (btw, I like the idea very much). I got all parts (except pump) for less then $20 inc. tax (I already have some elbows, tubing etc... from some other projects). So, yes I will go with your suggestion. I have a question for you, however. Original author talks about 12V pump on water level (float) switch. What do you use for water injection to the reactor?
Thanks.
