    New member, new problems!

    2018 351M Momentum Nautilus NP1

    Greetings!
    Went through the deep freeze recently in Tn. Unhooked from the city water connection, drained down to the low points, set the thermostat on 45 and went to ride out the cold with family. At some point, the propane ran out...
    After several plus freezing days, we returned and hooked up the city water to find only a trickle of water at the rear bathroom sink (hot and cold, I believe) AND the water inlet on the toilet leaking into the bowl. No water at the kitchen or master bath/shower. Water DOES drain at the low points. At the faucet in the bay, I have only cold water. Nautilus settings are correct. I have cleaned screens to the intake at the nautilus and verified flow. Running about 50lbs pressure at the spigot but have tried higher. No signs of leaks from the underbelly or in the crawlspace.

    As everyone knows, a diagram is non-existent...unless someone has made their own. Just a flow path would be incredibly helpful.

    Please help!!!

    It may not be completely thewed yet. The low point drains do not get all the water out. I suggest leaving the city water turned off when you are waiting for the thaw. only turn it on while testing. What about the waste tanks? Are they draining? If you make it through with no leaks, man, head to Vegas.

    Also. Crank up the furnace and get things nice and warm ( say 70+ )for a day or so.

    I would bet everything is not thawed yet also. I would be concerned about the Water Heater too. If you didn't drain it, there may be issues!

    Welcome to the group.
    I also agree that you may not be all thawed up yet. Crank up that furnace and please keep us posted.

    Funny thing is, we just came from Tucson!
    We drained the waste tanks before we left and haven't really accumulated anything in there. I'll run some water into the flush when I get back over there.
    Thanks!

    Don't like the sound of that. What kind of issues we talking here? Rupture? Clogging?
    Should I just go ahead and plan on flushing it while I'm doing all this stuff anyway?

    Thanks!

    How about the leaking toilet? Too much pressure from a freeze down the line? Damage form the freeze itself?

    Thanks!

    I've been behind the pass through storage wall and its a maze of water lines. Doing suspension work recently, I found the rear toilet/sink lines running along the frame on the roadside/driver side of the unit. I'm not sure if the kitchen sink lines "t" off these lines. I have discovered with our unit that the "low point" drains do not drain everything. I usually pull the anode out of the water heater to help things along. The first time I used air to purge the lines, A LOT of water came out. Like about 3 gallons. If I remember correctly, the low point drain valves are at the same level of the floor, top of the I-beam frame. It seems that the water lines for the kitchen and rear toilet hang below floor level, "sagging". I just realized this as I am typing. This should be why there is a lot of water left in the lines. Not real sure but I will be looking into it this weekend. May be another project to install real low point drains at the rear toilet lines which would truly make it the "low point".
    I agree with others with turning up the heat and giving the unit time to warm up and defrost. The toilet leak sounds like the foot lever valve may have cracked from the freeze.
