FLUSHINGlushing procedurePROCEDURE

Removal and/or fitting of check valves for maintenance

Important: It is preferable to flush the pipework before installing the valve. Where this is not possible, the procedure using a flushing cartridge should be followed.

a.Isolate the supplies.

b.Remove the trim ring by twisting anti- clockwise.

c.Remove the valve cover.

d.Remove the four screws holding the valve cartridge, and carefully remove the cartridge assembly from housing (fig.50).

e.Insert the plastic tool provided into the inner sleeve located inside the elbow and twist anti-clockwise (fig.51). Take care not to damage the check valve.

Note: The sleeve may stick, in which case it must be carefully hooked out using a suitable tool such as an allen key.

f.Push the flushing cartridge into the housing (fig.52). Attach a hose to the flushing cartridge outlet and make sure it is directed to waste. Flush the pipes clean.

g.Wash out the sleeve and check valve. Take care not to damage them.

h.Replace the check valve into the sleeve, making sure it is in the correct way (fig.53).

i.Refit sleeve into the elbow. Carefully replace the valve cartridge and refit the cover.

j.Reinstate supplies and test the valve operation.

Note: It may be necessary to service the check valves at regular intervals to prevent cross flow of water.

Note: Flushing cartridges and replacement check valve tools are available from Triton Customer Service.

Flush the pipework to clear system of debris and check for leaks.
