Understanding Water System


I recently purchased a used 2002 Leprechaun and this is my first RV. I discovered that my hot water heater has a crack. To replace it will be around $600. I would rather not do that right now since I will only be making one trip this year and storing for winter. My question is this when I shut off the water going to the tank shouldn't I be able to still hook up city water and use cold water only? How come water still drips out of the hot water drain valve? I was thinking that when I make the next trip I would be able to hookup and not have any problems but when I tried it in driveway I noticed this constant drip. Any hep would be appreciated thanks

Welcome to iRV2.

If you have a 3 valve , water heater by-pass , with the valves in the correct position , there should be no water entering the tank.
Any water entering the tank could be an indication that the cold in or hot out valve is leaking.
There are plastic plugs available , at RV parts stores, to block the line fittings that screw onto the tank , you'll need two and they are about a dollar each.

If your shower heads have a shut off at the head, make sure they are off and the faucets are shut off instead. If the faucets aren't off it may feed back thru. Check outside shower also if you have one.
