Description
The Watts RK 757/757DCDA-CK1 10 is a genuine first check kit for 10" 757 / 757DCDA double check valve assemblies. It features a silicone seat.
This 10 inch first check kit is made to repair a double check detector assembly used primarily on fire sprinkler lines when it is necessary to monitor unauthorized use of water and to help prevent the backflow of pollutants that are objectionable but not toxic, from entering into the potable water supply. It is designed for non-health hazard applications and may be installed under continuous pressure service to protect against both backpressure and backsiphonage. The kit consist of a first check module, check module O-ring and a disc elastomer.
Features
- Red silicone disc
- Can be installed in either horizontal or vertical position
- Serviceable without the use of special tools
- Extremely compact design
Common Questions
- Will this kit fit my valve?
- The RK 757/757DCDA-CK1 10 fits the 10" size of Watts series 757 / 757DCDA. Kits are size- and series-specific, so match the model stamped on your valve body or cover before ordering.
- What's included in this kit?
- This is a first check kit. Kit consists of: a first check module, check module O-ring and a disc elastomer.
- Are these genuine Watts parts?
- Yes. This is the factory RK 757/757DCDA-CK1 10 kit built with genuine Watts OEM components. Aftermarket parts can void your assembly approval and are commonly rejected by inspectors at annual test time.
- Which kit do I need if my relief valve failed the test?
- Not this one — this kit services the check valve. A failed relief valve needs the RV (rubber parts) or VT (total relief valve) kit for 757 / 757DCDA in your size; a total repair (T) kit covers the relief valve and both checks.
