Questions
Which Watts 919 repair kit do I need?
Match the kit to the model and size on your assembly's body or ID tag. Products on this page are grouped by part type, and each product title lists the models it fits. Lead-free models start with LF, so check for those two letters on the tag.
What sizes of Watts 919 parts do you carry?
We carry Watts 919 kits and parts for 3/4", 1", 1-1/4", 1-1/2" and 2" assemblies. If you don't see your size, contact us with the model and size.
What type of backflow preventer is the Watts 919?
The Watts 919 is a reduced pressure assembly (RPA), sold lead-free as the LF919. Reduced pressure assemblies are used where the hazard is high (toxic), because the relief valve vents water if the checks fail.
