How much water pressure in 12 volt pump?

[Wingdreamer]

I am thinking of hooking up a 120 volt water heater in my pop up to supply better half with hot water. Manufacturer of heater states that it needs a minimum of 25psi of water pressure to work. Any idea what kind of water pressure the 12 volt pump that comes standard in a pop up will produce?

You'll have to check the specs on your pump.  Most 12 volt RV pumps have a pressure switch to turn the pump off at 30 to 50 psi depending on the brand and model.  Just enter your pumps model number on Google or Bing and you'll find the specs.

Thanks for the info! Will have to wait till spring to get the pump model #, but would think that it would have at least 25 psi to do the trick.
