Strainer Servicing
SUPPLYRETURN
1. Turn the lever handles on both
Hydro-Core ball valves so that they
are parallel to the  ange. The T-Flow
handle logo indicates the  ow pattern
inside the valve. The logo should
indicate that  ow can go through the
purging valve and both the supply
and return piped assemblies.
2. Release internal pressure by removing
the system return purging valve cap
and turning the drain handle on the
system return purging valve into
the open position (parallel with the
 ange). Pressure release should
emit a small amount of  uid.
5. Reinstall the plug, ensuring that it is
seated properly in the strainer cap.
3. Remove the strainer plug by
turning it counterclockwise.
4. Clean out the strainer.
6. Close the purging valve (drain handle
perpendicular to the  ange).
7. Return the lever handled ball
valves to their normal operating
position (handles perpendicular to
the  ange) and replace the cap.
8. Pressure test the system to
ensure that all connections
are pressure tight.
