Coleman hot water on demand - submersible pump?

[threedogs]

If you had the correct tap could you re tap the thread thats compromised.??

Also the pump can sometimes fail to pick up. If so, shake it back and forth in the water like your trying to revive a fish but faster.[/QUOTE]

I take it you do this as there is a non return valve on it somewhere?

Im not sure. The water runs back out if you drain it. I possibly have crap in mine from a lot of creek pumping.

Yep the best thing I bought for that was the 9kg adaptor. Haven't really used it for showers much, mainly washing the baby bottles but I want to start using it for showers for the girls.

I would think any pump would benefit from a non return valve in the system somewhere

No return valve (I think they are worried about ice maybe blowing out the core overnight or when stored in cold climes) but they do have a float switch type setup, well. at least the earlier ones do.

Thats why you have to have the "this side up" of the Pump roughly "up"

The biggest problem with crap build up isn't in the pump.
The heat exchanger has very fine cores so it is very easy to block with algae, mud, leaf matter etc

Also, I agree with a prev post for showering.
Grab a large bucket or small bin/clothes basket and use the Coleman to heat the water in that IE both the pump and outlet are circulating in the bucket and warm that water to the desired temp.
Grab a 12 Volt Camping shower (the coleman is only a 6 Volt pump and the flow at above human head height is a tad sad) and use that for the actual shower.

I wonder if it would work if you replaced the pump with a 12v camp shower pump. The extra flow might require more gas to keep the same temp but I don't see how it won't work. I don't mean totally rewire the unit, just remove the old pump from the hose and disconnect the lead from the unit and somehow plumb the 12v pump to the hose running from separate 12v battery.

Do you freeze the empty cylinder before filling?
