ABSTRACT:
This invention pertains to a water recycling system for economy in water consumption by dental evacuating equipment employing a water seal type pump and includes a storage tank for waste water received from the pump, a fresh water tank above the storage tank, and an air and water separator compactly arranged with said tanks, passage means between said tanks to permit makeup and flushing water to pass from the fresh water tank to the storage tank and flush the latter through syphon mechanism, except residual seal water remaining in the pump. Conduits extend from dental evacuating equipment to the pump and then to the air and water separator to vent air to atmosphere and pass waste water to the storage tank, and an additional waste water conduit extends in gravity-flow manner from the storage tank back to the pump for recycling and economy in water consumption. Timer mechanism effects discharge of the waste water to sewer from the storage tank after non-use of the pump for a predetermined period of time, such as at the end of the day, fresh water then also being discharged to said storage tank from the fresh water tank to purge the same and prepare for re-filling with fresh water at the commencement of operation the next day.
