6-5-10-6-11: Those are water drain lines. The caps are missing off of them. You do not want to connect them together because your hot water and cold water will mix.

Tiger851: Some people install a ball valve in place of the caps to make it easier to drain and no caps to loose. I haven’t gotten around to it, but I place the caps in hot water heater area so I don’t loose them.
