External Shower - Coromal

I had a similar problem recently and found that the temperature limiting valve was not allowing hot water through the valve. This valve is located under my van and looks like a brass valve fitted to the hot water discharge line of your heater. There will also be a cold water inlet and a hot water outlet from this valve.
There will be a plastic cap on the top of the valve, remove this then open the adjustment nut on the top of the valve, my understanding of the pupose of this valve is to mix cold and hotwater together to prevent hot water getting too hot and scalding you, when not used for some time they stick and stop the hot water coming through the valve. Before adjustment maybe first try a light technical tap on the body of the valve with a hammer this may loosen it.
Hope this helps

It wouldn't be something as simple as the on/off sliding clip on the hand regualtor would it? Could be stuck.

We used to have a 520 Off Roader and had a similar problem, turned out to be a kink in the pipe.

Hi DB

Just before you start whacking things with a hammer, and altering the Temperature Setting on the Mixing Valve, first check the Filters Strainers on the valve first to see if they are blocked,quite often this is the problem, NOW TO ALL THOSE OUT THERE WHO LIKE TO EXPERIMENT, these valves are designed to stop people from being SCALDED, they are installed by Licensed Plumbers as part of the Plumbing Regulations, we use a Thermometer to check the mixed water temperature, which is ranges between 40 to 50 degrees celcius, I shudder when you read these so called DIY Boys trying to give advice when a Child or someone could get SCALDED.
