Frozen water lines

[TheQuietts]

Our water line froze for 2 days. The highs are still below 25f. I put a heated water hose on and water is running in both sinks and shower. Buuuut, there is no water running in the toilet.

Sounds like you my be chasing a small piece of ice in the feed line to your toilet.
I’ll take a WAG and say you have two choices to start with:
Increase the temp inside maybe even place a small non red element space heater in the bathroom and give it some time ,
Use a hair dryer around the base of the toilet where the water line comes in or heat gun. Heat gun would not be my first option as if you find yourself getting impatient, those things can cause a lot more problems to your interior fixtures.
Again this was just a guess because I’m not sure how your rig is set up.

Agree with Skilletface - a little broken up ice can block the water line. Heat lamp, electric heater, hairdryer etc to try to thaw out the ice.

Do you get any water thru? A trickle. In my case I saw a trickle.

When water lines freeze, many unpleasant things can happen. Of course the external hose to the pedestal faucet will be the first to freeze. All water flow is blocked. As you found, a heated hose often solves that problem.

Water pipes under the RV or in unheated places can freeze. Water flow to one or more faucet is blocked. Sometimes you can find the exposed pipe and thaw it. Sometimes it is not easily accessible. Wait for warmer weather.

Modern RV's use PECs tubing for pipes. PECs is flexible and usually does not break when water in it freezes. Fittings used join sections of PEX may or may not be so flexible.

Valves, like toilet valves, tend to break when water freeze in the valve. It could be the linkage used to operate the valve breaks when operated with force against the ice. It could be the valve body itself bursts.

Watch out for flooding when things thaw. Replace broken parts as necessary. Take mitigations step to prevent freezing next time. Let water drip or trickle when temperatures drop below freezing.

If you can get even a trace of water to flow into the toilet, hold the valve open. Let it trickle. Flowing water, even a trickle will often thaw an ice blockage.

In the future, use a thermometer to measure water temperature. Let water trickle for a while, then measure temperature. When temperature of the water drops below 38 degrees F, it is time to increase flow from a drip to a trickle. Keep it moving to keep it thawed.

Insulate or add heat tape to exposed water lines to prevent future freeze ups.

I wish you good luck and happy trails ahead!

That happened to me before and what worked for me was running the hot water at the closest fixture. My toilet wouldn't work so I ran the hot water in my shower until the hot water ran out. The hot and cold water lines were close enough that the heat radiated from the hot line to the cold line and unfroze it.

If you have low point drains it could these are still frozen and ice has blocked the water flow. Look at these and check if it is frozen. We had that happen in Chattanooga in November 2019. If this is so wrap your drains with pink insulation and we then put the gray pipe insulation on it to help.
