Backflow prevention assemblies can reduce or eliminate backflows by segregating drinking and non-potable water piping. This is done either by providing an air gap or by installing a backflow prevention assembly (BPA) between the two plumbing systems.
Winter Storm Updates
As a result of wide-spread freeze damaged backflow preventers, a supply shortage is being reported. Austin Water Special Services has developed an alternative compliance method. Plumbers and property owners may install a spool piece until a new backflow preventer can be installed. In order for this method to be in compliance, plumbers and property owners must agree to deactivate the hazards that could potentially backflow and introduce contaminants into the system. Documented agreement must be submitted. Failure to adhere to this temporary agreement or in the event of a violation to these conditions, plumber or property owner face possible criminal complaint.
Austin Water will update this temporary change once inventory of backflow preventers return to normal levels.
