Safety Valve
Two 17mm/ 11/16 inch spanners (wrenches) are required to replace the safety valve – one for holding the valve on the underside of the lid and one for turning the nut on the top of the lid. 
A food compatible sealant or glue is recommended.
One strong person can replace the safety valve as stated below.

TO REMOVE

1.  Remove the sealing ring and pressure regulator from the lid.

2.  Hold and brace the lid on a soft surface such as a folded cloth with the left hand. Take care not to bend or warp the lid curl. Do not hold the lid by the handle. With the right hand, place the spanner around the nut on the top of the lid (see Picture alongside). Exert downward pressure on the nut just until it loosens.

3.  Place the ring end of one spanner on the valve on the underside of the lid and hold it in place with the thumb of the left hand while grasping the lid with the same hand (see Picture 2). With the right hand, place the other spanner around the nut on the top of the lid (see Picture 3). Exert downward pressure on the nut. Remove and re-apply spanner to the nut on the top of the lid at a higher angle. Repeat downward pressure. Repeat procedure until the nut can be unscrewed from valve with fingers. Remove nut, washer and valve. A factory-fitted safety valve does not include a washer. Discard all parts; do not reuse any part.
