Hi all, my water heater is 'dripping' from an overflow(?) that is connected to the hot water outlet and making the pump run intermittently. I have just been on holiday with no problems but am now back on site as I work away. The hot water outlet is a 'T' piece, with hot water going one way and a drain going overboard. The van is a 2004 Bailey Senator Oklahoma. Any help appreciated. I still have a months warranty left as I bought it 11 months ago. Thanks, Gary.
