6 Inch SPP Box 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)

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

Lift this lid up, inside you will find a rubber NRV Flap,

Picture 1 is the NRV Flap in place, and picture 2 is the flap removed.

Simply lift the flap up/off and ensure the seat and surrounding area is clean and free from any stones, twigs etc.

Please make sure the rubber gasket is clean and not damaged.

Replace this cover and tighten all bolts.

If the pump still does not prime and pump, and the suction line is clear/unblocked –  you are going to need to contact our 24 hour phone number – 01329 229 800

An engineer will be in contact with you shortly.

2. Engine runs but only pumps limited amount of Liquid

a. Make sure the Suction strainer is not blocked with debris.

b. Make sure there are not too many suction hoses

c. Ensure there are no collapsed, kinked or damaged suction hoses

d. Remove the suction hose from the pump and check there is nothing inside the impellor (pic below indicates the suction port on the lower left side)

The Pump Must Be Off

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

f. Check the engine speed – this can be adjusted using the manual throttle or the “Rabbit and Tortoise” buttons

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

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

3. Engine will not start or run

a. Check the “E STOP” button is in the OUT position

b. Check the battery terminals – make sure they are tight and secure

c. Check the fuel level in the fuel tank – Open the fuel cap and look inside – often the fuel gauges get stuck in the FULL position

d. If the pump has run out of fuel – please inform our engineer – he will need to reprime the fuel system

e. Check the inline fuel filter is clean and not blocked up with sediment

f. Allow the engine to go through its startup cycle before trying to restart again

Please do not continuously try and start the pump, this will deplete the battery and potentially damage the starter motor. If the pump wont crank and start – please check various points above then report the failure to avoid any additional costs to yourselves.

4. Flat Battery

a. A flat battery is a very common occurrence – this happens when the pump is not turned off completely. The engine has stopped and the ignition is left on. This will drain and deplete the battery

b. Is it possible to connect a set of Jumper Leads and jump start the engine?

c. If this is not possible – you will need to contact our office and an engineer will replace the battery. There may be a charge for a flat battery call out.

Please ensure that you adhere to the daily maintenance schedule – if this is not done daily – mechanical failures may result.

All the above scenarios are possible issue of a nonfunctioning pump, these issues can normally be rectified over the phone.

However – if you are not competent or unsure – please do not attempt to rectify or fix the issue. Please call our 24 hour phone number – 01329 229 800
