hydraulic jack to correct them.
Connecting pipes and components
Attention!
When maneuvering the steel pipes, inspect the pipe for any scratches
in the coating. Coat all scratches with tar to protect from corrosion;
Attention!
Pipes must be surrounded with sand and carefully backfilled under the
frost level.
Attention!
All gate valves with insulated rod and PVC elbows must be embedded
in concrete to avoid pipe dislocation.
Refer to section on Protection against corrosion of the steel
evacuation line
The complete evacuation line must be buried in fine compacted sand. Sand
protects PVC pipes from rock piercing and protects against corrosion.
● Lay the pipes on 6” [15cm] of compacted sand.
● Perform a leak test according to the local regulation.
● Surround pipes with sand and
compact it using a piece of wood as
illustrated.
