Water Pump 12v draw

[flyflotrtim]

Can anyone advise how much electricity is used by the water pump in our 2205 Minilite? ( AH if possible) We have 2 standard wet cell batteries that are new and check well. We almost always boondock and use our lights and pump sparingly, no other electric usage other than the parasitic draws and juice needed to unhook and put down the levelers and move out the slide. Our 100 watt solar panel puts out about 18-20 AH a day when camped in mostly shady spots. By out 6th day our batteries are down to about 12.26 volts from an initial 12.8 (14 hours after unhooking from shore power). So our solar panel is not keeping up and I suspect it is the pump responsible for the drain. Alternatively perhaps the batteries are largely depleted from our initial camp set up.

thanks all.

I've replaced the factory pump with a Shurflo brand, but when it initially comes on it pulls right at 3.4A and then as it's getting close to shutting off it creeps up to around 6.0A.

An average water pump will use 5 amp hours if you run it for an hour.

Most pumps put out around 2.5 gallons per minute. Chances are the only time you use that much water is for a shower.

With this in mind I'm guessing a water pump runs for maybe 1-2 minutes per day in total if not showering thus power consumption by pump will be less than one amp hour per day.

A furnace is usually the biggest user of battery power but only when cold.
