If you own a Hydramaster, seriously consider replacing these PLASTIC fittings that connect the heater hoses to the heat exchangers. We've had three different units where the fittings have failed, overheating the engines due to coolant lost. The last failure may have cost us an engine. When the fitting fails it sprays coolant inside the van while the tech is unaware working in the house. Why Hydramaster would use cheap plastic fittings on such an important connection is beyond me.
We are in the process of replacing all their plastic fittings with brass in all our units.
