When we are running the gas mode on water heater,,,a small puddle of water appears on top of linoleum floor at corner of sink cabinet. I realize the location could change based on rig leveling. Point is we have a leak. Any ideas what this could be from. Problem is the same if using any of the sinks or shower. If tank is off,,,,no leak,,,
Are you referring to the bathroom sink cabinet? The water heater is located underneath the bathroom sink. I would start by removing the panel and checking the plumbing connections in that area. It might be a defective tank as well but again it would involve removing the panel to inspect it. Since you are under warranty I would take it back to the dealer to let them handle with it.
