Hi sorry if this is a really stupid question, we have just bought our first proper Motorhome, it’s an elddis sunseeker 35. We cant work out where the drain valve is, we thought we had filled the van with water but nothing came through the taps so I’m thinking the valve was open when we tried. I’ve looked everywhere I can think of for the valve but can’t see it. Also when my husband was trying things he put the switch for the ultrastore on and it’s tripped the electrics on hook up so I don’t know if he has now broke it. Any help would be welcome.
