Rebuild Your Watts SD-3 Backflow Preventer

Stop leaks and ensure your water supply stays safe with this internal repair kit. The Watts SD-3 is a standard in beverage dispensing that keeps carbonated water from backing up into your copper plumbing. Instead of cutting out the whole valve when it starts to fail, you can swap these internals to get it back in service.

This kit includes the rubber O-rings, check modules, and diaphragms required for a full rebuild. It works with 1/4" and 3/8" SD-3 models commonly found on soda fountains and coffee brewing equipment.
