Abstract
A method for purging water from flooded expansion tanks without necessitating the complete drainage and subsequent refilling of the systems allows for a stabilized hydronic water system in much less time with less effort and expense.
Claims8
A method for the purging of water from a flooded expansion tank in a hydronic heating system comprising:
- a) calculating the volume of water equivalent to one-half the volume of the expansion tank;
- b) pumping air into the drain valve of the expansion tank;
- c) opening the drain valve of the associated boiler unit;
- d) draining an amount of water forced out by the air in an amount approximately equivalent to one-half the volume of said expansion tank and;
- e) closing the valves.
A means for purging water from a flooded expansion tank consisting of an air source and a flusher component comprising an air valve, a bushing, and a dual female connector for attaching the air source to the drain valve of an expansion tank in an hydronic heating system.
A means for purging water from a flooded expansion tank consisting of an air source and a flusher component comprising a Schrader air valve, a bushing, a dual female connector and a flexible hose for attaching the air source to the drain valve of an expansion tank in an hydronic heating system.
