I use a 12v demand and a sink sprayer nozzle to get much more water pressure. My setup allows me to recirculate the water in a 7 gallon plastic jerry can. That way I bring the water up to tempurature before showering. I can then turn the water on and off without having to worry about having flow through the heater unit.
I've got a 2 burner also, with the 12v pump and the propane tank holder.
You mention and sink sprayer nozzel on/off.... do you have a pic? I was planning on using a 8 gal plastic bucket (restaurant bucket) but have to keep the nozzle back into the tank if not using it. Have already used the D-cell and discovered it went out - just stopped cold, got the burners red hot and partially melted the rubber hose.
do you have a pic of the nozzle? on/off? or do you have it split so the water keeps recirculating until the nozzle is turned on... If that is possible.
thanks...
was trying to set it up last trip, but never got the time.. so many things, so little time... LOL...
