frozen sewer hose and water line

I haven't had water all day because my line must have froze and so after lugging jugs of water back and forth in order to do dishes I notice my sewer hose is now frozen. Any advice on what to do would be greatly appreciated.

WHY are you leaving your black tank sewer blade OPEN?

Whether you are just RV'ing or 'living' in your RV you leave the black tank closed. Let it fill to 3/4 and then dump.

The reason your sewer hose is frozen is because there is waste just sitting it in, now frozen.

Waste needs WATER to move. That also means there is most likely a mountain of poop in your black tank also.

Leave black tank closed when 3/4 fill dump. That water takes all of it out and completely down the sewer hookup. NOTHING should be in your sewer lines.

Frozen water line:
In freezing temps you need to:

Disconnect water hose from spigot and your RV.
then Drain the water hose.

That way come morning when the temps rise you just reconnect the hose and you are back in business.
