6 Inch RT Trouble Shooting List

6” ROAD TOW PUMP – TROUBLE SHOOTING LIST

Please remember – you must ensure the engine/pump is isolated and cannot be started.

1. Pump Does Not Prime Or Pump (Engine Is Running)

Turn the pump off and isolate

a. Check that the end of the suction hose is submerged and not drawing in air

b. Check the strainer is not blocked with a rag or leaves etc.

c. Check all the suction hoses are connected, not squashed flat and not drawing in air

d. Disconnect the suction hose, look inside the suction port and ensure there is nothing blocking the inlet or lodged in the impellor

e. Using a 24 Spanner – remover the NRV Cover plate indicated in the picture below

Under this lid you will find a rubber NRV Flap,

Below is a picture of the NRV Flap in place

Below is a picture of the NRV Flap removed

Once the flap has been removed, look for any small stones, twigs etc on the sealing surface, clean this surface and replace the rubber NRV flap.

Replace this cover and ensure all the bolts are fully tightened.

If the pump still does not prime and pump, and the suction line is clear/unblocked, there are no crushed or flat suction hoses – you are going to need to contact our 24 hour phone number

d. Remove the suction hose from the pump and Check there is nothing inside the impellor (pump must be off)

e. Check the discharge line has no kinked or squashed pipes.

f. Check the engine speed – this should be around 1700 RPM.

g. Make sure the strainer is not sitting or buried in mud.

h. Ensure the suction lift is not greater than 8m deep.
