Check cover assemblies for backflow prevention assemblies with integrated test cock protection shroud

A check cover assembly for a backflow prevention (“BFP”) assembly having a bucket defining an interior for containing a check valve assembly, the check cover assembly comprising:

• a ball with a central aperture and a groove in an outer circumference of the ball;
• a base for closing the bucket of the BFP and including:
• a shroud portion within the base and housing the ball to create a ball valve, the shroud portion defining an access gap;
• an actuation feature with a protrusion mounted in the access gap so that the protrusion engages the groove to open and close the ball valve;
• and an opening;
• and
• a test cock coupling attached to the opening and in fluid communication with an interior of the bucket of the BFP assembly, the test cock coupling securing the ball within the shroud portion and configured to connect to testing equipment,
• wherein:
• when the ball valve is open, the testing equipment is in communication with the interior of the bucket,
• when the ball valve is closed, the testing equipment is not in communication with the interior of the bucket and may be removed,
• the ball valve comprises a lower seal piece and an upper seal piece that sandwich the ball in the shroud portion to prevent leaking,
• the lower and upper seal pieces are o-rings configured to create seals against the ball, the shroud portion, and the base,
• the check cover assembly forms a hollow to create a socket, and further comprising a spring bias assembly having a first ball end in the socket to form a ball-and-socket joint and allow rotational movement of the ball end of the spring bias assembly, wherein the spring bias assembly is configured to extend to a second end that urges a sealing disc towards a closed position on an opening of the BFP assembly, and
• the base is dome-shaped, and the base and the shroud portion are unitarily formed from a composite polymer.
