2.6.3
Leak tightness and blockages
Regularly force water through the delivery line under operating pres‐
sure to check that the system is watertight.
A properly cleaned delivery line is the best insurance against the for‐
mation of blockages. Blockages increase the risk of accidents. Never
attempt to push through a blockage (e.g. by increasing the delivery
pressure, using compressed air, etc.). There is a risk of death from
the delivery line bursting or from concrete being ejected from the end
of the delivery line.
Prevent blockages by adjusting the operating conditions. Remove
blockages by reverse pumping and then restarting forward pumping.
Repeat this process several times if necessary. If the blockage is not
removed, relieve the pressure on the delivery line before removing
the section of delivery line concerned.
