Heat xchanger went fufu today. Blowing water out exhaust.

Can one of yas clue me in what this may cost to repair/replace.

further, can one of yas splain me how to prevent it next time?

When the heat exchangers blew on my SteamAction, I switched to propane. Little Giant 3HT. It took some modifying but the unit is much more dependable now.

That thought did occur to me but I want to fix this one..

then sell it.

defently sure your waste tank is not full then if you think your heat exchange is a fault force feed your pump with a garden hose from the inlet side with the engine switched off and look for the leak
(thats if you dont know wear it is allready)

Hopefully you will find a burst hose if not you may need your exhange welded up

Good luck
