THOR #5648
Frozen fresh water tanks

Hi First I want to say thank you for the help with the TV booster power button, in my Thor ACe 30.2 RV. I was able to locate it and now can say that I have TV!!

The second issue I posted for help on was the coach generator. The coach was taken directly to OnN, and they were not able to find any problem with the Generator. Because I was supposed to go to York, Pa tomorrow, I picked u the coach yesterday AM. The techs, filled up my fresh water tank, and did not turn on the heat. I now have FROZEN water lines ......

I have opened all the cabinets, turned the heat upo 75-80, and run that for 26 hrs. I still have no running water in the bathroom sink and shower, or kitchen sink. The tank heaters are onand I have also put electric space heaters in the bathroom as well.

I now have a bad case of the flu and I won't be going to my dog show. Any more suggestions on getting things defrosted??? So my husband can take t back to my storage place...... ready to sell this thing!!!

If the water tanks was full and froze solid I would suspect that would take quite some time to melt.

In addition: If there was water in the system and that froze I would suspect quite a bit of damage, including a cracked water pump (which would prevent water coming from any fixture) and pipes broken. I would find where the tank/pump/etc. is in the coach and inspect all of that for leaks.

Open as many access panels, drawers, doors, seats that you can find. A hair dryer will help direct hot air into the places the pipes are hiding. Another thing you can do is fish a shop vac hose into places you can't reach and put it on the exhaust outlet side to force more warm air in.

Its unlikely the entire fresh water tank would have frozen solid in 24 hours... though the lines certainly can.
Need to give it time to fully defrost before you will be able to get any water flow - and check for leaks/damage.
Hopefully the actual ice blockage is in a small section and survived without splitting.

(Tanks heaters won't help much - as they heat the gray/black drain tanks - those are likely fine as they have room to expand (except the pipe to the gate valve)).

I completely agree with gmc, very unlikely the tank is frozen, it would taken quite a while for that to happen! I also agree that you most likely have an ice blockage somewhere, unless the temp was extremely low you might get lucky and not have any damage. Keep up the heat and give things a chance to thaw. If you have access to your water tank make sure that area is open to the heat. Got my fingers crossed for you!

Can you get the RV to a heated space and let it thaw?

I had mine freeze but not as bad as yours. My tank was empty and I had opened the low point drains but did not pump any antifreeze through the system so I ended up with ice in low points and in the pump. Even after I got all the lines thawed and the temp in the RV up to 70 iI could not get any water through the system. The pump was running but there was just enough ice in it to stop water from being drawn in. I used a hair dryer to warm it up and let it set for an hour after that and it started working. The only lasting problem was that now my water pressure seems to bleed down in about a half hour which it never did before. I hope its just the one way valve and not a leak some place.

Anyway to return to the dealer? Frozen tank/lines are their fault, they should be able to put it inside to thaw and repair any problems. PEX tubing is somewhat tolerant of freezing so hopefully damage will be minimal.
