I purchased auto-vent air valves to help with air in my hot water gravity feed ratiators. I have problems with the one furthest from the boiler. I purchased "MAIDOMIST". This manufacturer recommends; "Screw cap down tight by hand and fill heating system. Open valve cap slowly by turning to the left (righty-tighty,lefty-loosy, makes sense) until water leaks throught vent hole at about 10 drops per minute." My quetion is: What do I do with the 10 drops per minute, 600 drops per hour, 14,400 drops per day, 100,800 drops per week, 432,000 drops per month, 5,184,000 drops per year? Is this more than a gallon? Should I invest in a bucket, or, just wait until my house rots away? Can someone suggest a better mouse trap? May-be a new bottled water source!
