1st trip after winter and all going well until a problem with the water heater system. Pump working well but when I switched the valve at the water heater unit from horizontal to vertical to fill the water heater unit the pump stayed on too long. Looking outside, I saw that water was pumping out under the heater unit. Presumably a loose connection or a burst pipe due to freezing; hopefully nothing worse. Too damp and muddy where I am so will use gas to boil water meantime but any advice would be appreciated. It's a Bessacarr E460 rear lounge where the water heater is located at the rear off-side corner. No sign of any water damage inside the van. I'm assuming (hoping) all water pipework runs under the van base and not internally. Thanks.
