Deep-Bury Adapter Kit Installation Instructions
Always be aware of, and follow local plumbing codes
Failure to follow these instructions could result in personal injury or property damage
Adapts ProCheck ™ backwater valves for deep-bury installations.
For use with Sioux Chief 869-S series ProCheck™ backwater
valves ONLY.
Backwater valves sold separately.
1. Remove the Threaded Lid and Carrier/Flapper from the Valve|
Body and set aside for later use (backwater valves sold separately).
Solvent weld the valve to the 3" or 4" Sch. 40 drain line on the
downstream side of the fixture(s) to be protected.
2. Measure and cut a piece of 6" Sch. 40 pipe to bring the access
point to the desired level (note length of Extension Pipe). Solvent
weld the Upper and Lower Adapters on each end of this Extension
Pipe. Thread the Lower Adapter (with o-ring) into the top of the Valve
Body and tighten. Measure and cut a piece of 1½" Sch. 40 pipe
to be 1⅝" longer than the Extension Pipe. Solvent weld this Handle
into the socket on the top of the Carrier.
3. Allow the Handle-to-Carrier joint to cure, and be sure the Flapper
is installed on the Carrier properly (Flapper swings freely, sealing
surface faces upstream, etc.). Using the Handle, lower the Carrier/
Flapper through the Extension Pipe and into the Valve Body. The
carrier is installed correctly when it sets flat/level in the valve body,
and will not rotate without being raised.
TIP: The Carrier uses different-sized lugs on each side to orient
itself correctly in the valve body. If the carrier seems difficult to
orient, or won't set properly, be sure the flow arrows on the carrier
point downstream.
4. Install the Valve Lid (with o-ring) into the Upper Adapter and tighten.
To access the Flapper after installation*:
Remove the Threaded Lid. Using the Handle, carefully pull the
Carrier/Flapper through the Extension Pipe. Regularly inspect the
Carrier and Flapper for debris, buildup, or any damage that would
prevent proper function and replace if necessary. After inspection
or maintenance, reinstall the Carrier/Flapper and reinstall the
Threaded Lid.
* Note: Harmful bacteria are present in sewer lines. Be sure to take necessary
sanitary precautions when inspecting installed backwater valves.
