If you've connected your HOTTAP Outing, and when the pump is on (and making noise) you have no water flow, or very little, try the following:
- First and foremost, make sure you've removed the red lugs from the pump inlet and outlet adapters. These lugs are placed here from the factory to keep the lubricating liquid inside the pump during transit, but need to be removed before use otherwise you will not get any water flowing.
- Ensure that your 12V supply is charged. If you are running from your car's cigarette socket adapter, try turning the car on. Some cars have safety mechanisms in place which turn off power to accessories when the car is off to stop battery drain.
- Check that all fittings, connections and adapters are tight. Also check that your inlet filter is clean and not blocked. Similarly, check the HOTTAP inlet water adapter for blockage.
- Try running the pump on its own - not connected to the HOTTAP water heater. That is, have the suction hose sitting in your water container, and the outlet hose running back into this container, to see if this makes any difference. If it still doesn't work, try removing the outlet hose totally, so that the pump is running with just the suction side - this will help the pump prime if that is the issue. Please keep in mind that there may be times when it may take a little while for the pump to actually prime fully so don't hesitate to leave it running for up to 30-60 seconds.
