Camplux BW422P120 Camping Water Heater Pump Kit

Love this hot water heater. We have a guest house on our property with an outdoor shower and our family and friends just love it. This was a great purchase for us!!! Easy to set up and use.

I have the 4.22 gpm version. The 3 gpm pump that came with it doesn't seem to put out enough water to run the shower on any water setting other than minimum. When I turn it up the flame shuts off. I'm also having issues with the flame shutting off quite a bit at a variety of different gas and water flow settings. Overall its been a lot of messing around to keep it running??
