Report "Yellow stuff My Rm hascraped out.. I find ammonia has leaked into the boiler unit. DOMETIC says to install a kit. This kit only shuts off the gas to prevent the trailer burning to the ground. After several call and a total runaround I am now really ticed-off. The unit is only three years old and a leak in the pipes is not from faulty care but from premature failier of a defective item. ANYONE GOT IDEAS? BTW Domectic has now sent me a recall notice.. Isn't that great!!"
