Out of all of the 12 volt appliances in an RV, the water pump usually is the one that uses the most power when running, around 100 watts.<\/p>\n
That doesn’t sound like a lot of power, but for a 12 volt system being run by batteries, it can easily overload the circuit.<\/p>\n
The high power draw can cause other electronics that are connected to it to stop working properly.<\/p>\n
Like the RV lights flickering.<\/p>\n
In this article, I’ll go over some of the common reasons for flickering lights when the RV water pump is running and a few things you can do to try and fix it.<\/p>\n

Dirty terminals and connections can reduce the power the battery can supply, causing flickering lights.<\/p>\n A loose ground wire is also another common cause of issues with the 12 volt power system in an RV.<\/p>\n Follow the wires from the batteries and relay to find where the grounding wire is connected to the RV frame. It may have come loose over time.<\/p>\n If the RV is plugged into a power source and the 12 volt pump is still making the light flicker the 12 volt converter in the RV might not be working properly.<\/p>\n See Also:\u00a0How To Install Solar Panel On RV Roof & Connect To Battery<\/a><\/strong><\/p>\n LED lights are sensitive to voltage change. That means if your 12 volt system is even just a little bit overcrowded or the batteries aren’t supplying enough power, they will flicker.<\/p>\n Also if the LED lights aren’t made to handle different voltages this could damage them and make them go out much faster.<\/p>\n A 12 volt circuit in an RV is usually connected to a lot of different appliances. The fans, lights, water pump, and 12 volt TV could all be on the same line.<\/p>\n Each 12 volt circuit is only made to handle a set amount of amps. If the connected appliances start to pull more amps than the circuit is made to supply the highest power draw appliance like the RV water pump will steal power from other devices.<\/p>\n If you’ve recently upgraded the 12 volt fan in your RV to a larger one that draws more power or added a 12 volt TV you may start to see the lights flickering when the water pump is running.<\/p>\n See Also:\u00a0Best Deep Cycle RV Battery (AGM, SLA, 12V, 6V)<\/a><\/strong><\/p>\nReasons an RV Water Pump Can Make Lights Flicker<\/h2>\n
