OSV Valves

Leo Member Posts: 770
If the tank or oil burner is replaced the oil line has to be upgraded with a sleeved line or an OSV has to be installed. If the oil tank is above the burner you need an OSV to protect the pump.
If you have an old line some proactive companies will recommend an upgraded line or an OSV.
