Thank you for your inquiry! The bonnet ring should unscrew counter-clockwise for you. If it will not unscrew for you, then I would suggest using a 50/50 or stronger mixture of tap water and white vinegar. Soak a rag in the mixture and wrap the rag around the bonnet ring area. Use tongs if necessary. Leave the rag in place for 15 minutes or so. This should help dissolve the calcium build up, so that the bonnet ring will unscrew for you. Remove the rag and attempt to unscrew the bonnet ring or you can leave it on so that you do not scratch the bonnet ring with your tool. Make sure that the entire valve body does not start to rotate as you do this. Repeat if necessary up to 4 times, taking care to protect surfaces that may be damaged by vinegar. The white vinegar can stain porous stones like granite, limestone and marble.
