Water Pump Not Working -- Very Cold Weather

Long story short, my girlfriend and I purchased a GD Transcend Xplor 247bh a couple months ago to live in full-time while we fix our house after a house fire. We're parked in our driveway, hooked onto main power service full time, and so far we have just been filling the fresh water tank weekly and running the water pump (rather than using constant city water from the hose) as to not have a hose constantly across the driveway.

We're very new to RV/Camper trailers, learning as we go. We live in the pacific northwest, and tonight temps dropped to 0 degrees or less over night.... And these zero degree temperatures are supposed to stay for a week.

The underbelly is fully enclosed and supposedly has a dedicated heat duct to keep things "warm" under there, so aside from the dump pipes that protrude from the underbelly, I wasn't really too worried about things freezing or breaking. We just wrapped the drain pipes, cranked the furnace, and crossed our fingers.

However, as of this morning, it seems our fingers apparently werent crossed enough and our water is not working :( Last night, right before temps plummeted, I filled the fresh water tank full, took a shower and went to bed. Today, water isn't running at all, from either sink, shower, or toilet.

I really don't think pipes would be frozen, but I don't have any way to know for sure, and I don't know how cold the underbelly is right now. The one obvious problem I can see is that our water pump isn't running at all. We have the control panel right inside the door, on the wall, and there's a switch for the pump. The red light is still illuminated. Normally as soon as you turn it on, you will hear it come up to pressure for a few seconds then shut itself off. Any time you open a faucet or flush the toilet, you will hear it run. Today, nothing at all. No sound, pump doesn't seem to be working at all.

I've checked the small breaker panel in the bedroom floor, nothing is labeled 'water pump' but none of them were flipped, and all of the fuses in that panel also appear to be good.

I don't know if there are multiple pumps, but the one I do know of is below the bench seat at the dinette table. I opened it up to look around, but found nothing of note other than the pump. In related forums I've seen people mentioning a dedicated fuse for the water pump, close by, but I'm not finding one anywhere. Not in the pump panel, and the wires go into the wall to an unknown location. I would assume that if lines froze over night, we would still at least hear the pump trying, but literally nothing is happening which makes me think electrical issue, or maybe the pump somehow completely failed.

I opened the large panel under the bunk beds, in the back-right corner of the trailer. I found all of the hoses and valves, a large styrofoam box over what looks like a water tank, but nothing of note to help me. The access panel outside in that area is for the gas water heater, it has some wires but didn't seem to be anything related to the pump. There was a 2A fuse out there, but again, I thinkkk everything in that panel is related to the gas water heater.

I've disconnected all the power to the trailer, flipped all the breakers, then turned everything back on and no change. At this point, I've hit a wall and getting really stressed out. We will have 5+ days of these sub-zero temps, and at least 8 days until we see anything over 32 degrees, and only just barely. We have no running water. And the toilet cannot flush.

At this point, I think focusing on water pump troubleshooting is where I should be looking, but I have no idea what to do next. Even if I grab my multimeter, I don't think I have a good way to probe the wires at the pump, I don't see how they disconnect. The pump is some sort of "Pentair" brand.

Any help or suggestions would be hugely appreciated. I was hoping to find a fuse for the pump, but I don't know where else to even look. We normally leave the switch for the pump on at all times since we run off the tank water, and it auto-shuts off when pressure is reached. For now I've turned it off at the control panel until I have anything else to try.

Ps, we have a heated garden hose, and I'm tempted to try just hooking up to the city-water full time until we get above freezing, but the faucet/spigot leaks badly when open and will turn the driveway into a complete ice rink if I leave it on. So it's not a great option, and really just circumvents our water pump issue. I'm also worried that might just fill up more water lines at the other end of the trailer which might be more prone to freezing and bursting.

Thank you,

Water Pump Not Running

I have a GD Transcend Xplor 247bh. We hit zero-degree temps last night and suddenly the water pump seems to be doing nothing at all. It used to turn on and run any time we run the sink or flush the toilet but as of this morning it won't run or make any sound. I can't seem to find a fuse for it, and checked all of the breakers.

We run off the fresh water tank, filling it weekly, rather than running off city water and having a hose across the driveway full time. I filled the tank before bed and a shower last night with no problems. The trailer has a "heated" fully enclosed underbelly, and we turned up our thermostat hoping to keep things from freezing. I dunno what happened, but we won't be over 32 degrees for 8 days and have nowhere else to live, so it's pretty dire. I've done a lot of research and troubleshooting I can think of with no luck so far. Any tips or suggestions would be hugely helpful.

Thank you,

If it’s cold and your trailer isn’t skirted, the low-point drains probably froze.

Thank you for the reply! ?

Those are the red and blue water lines that hang down below the underbelly, right? If they freeze up, you think it would cause the pump to completely stop running? Or maybe burn out completely?

I can go outside and see what I can find. If they appear frozen, I can try to thaw them out.

The pump is pressure sensitive, so if the lines are frozen and the pump doesn't sense a drop in pressure, it won't run.

Thank you so much for the reply!

I just put a tiny space heater we had, outside pointed at the blue water line that hangs down below the tank and pump area. Not sure if it will help anything, as that one is just an open pipe -- I've seen it drain water out of the tank when I over-filled it once, but I'm not sure exactly what it is.

I'm about to go buy some tape, then attach a make-shift skirt of reflective insulation all the way around the base of the trailer to the ground. Maybe that will help hold some of the radiant heat from the trailer down below and warm the pipes back up...
 
I’m not sure where you are in Washington, but where I am we have only gotten to 9 degrees for a high and a wind chill of -6 right now. I’m afraid to say but I think every water line in the belly might be frozen. I know even in my Refection it would be very hard to keep anything below the floor right now thawed. Last night around here we got to 4 degrees with a -15 wind chill it is pretty hard to keep things warm in these RVs with the little amount of heat that gets directed to the belly. You might need to skirt your rig and put a heater in there to warm it up and keep it thawed.
 
there should be a troubleshooting area in your grand design regarding the water pump
I do know that it won't work if there is no water in the fresh water tank and of course you have to turn on the water pump power button.
Ok I looked in my book and this is what it says: If the pump will not start:
check that hosue battery disconnect switch is On.
check fuse in power center
check to see if water is frozen
Good luck
 
I replied to your other post but I too, am in the state of Washington and our high today was 9 degrees with a -6 degree wind chill. Last night it was 4 degrees with a -15 degree wind chill. I think your water lines in the belly are probably frozen, I know it is very hard to keep them thawed with the small amount of heat that is directed into the belly on these rigs. If your rig was skirted and had some heat under it you might have a chance in these temps. As cold as it is here and with the high winds I would also be worried about my hot water tank.

Hey, thanks for the reply! We're in Spokane, it's been crazy. Yeah, I'm starting to think that must be the case. I'm kind of at a loss at this point, we might just have to wait it out unfortunately. I have tried to attach our material we bought for a skirt and the tape won't even attamot to stick to anything in this insane cold :(

Hey, yeah, sorry! Spokane WA. I double posted because I'm new to the forum and wasn't sure where the best visibility for the post would be. I appreciate your input again! I turned on both water tank heaters, gas and electric, and I read that it should be fine to use both. At this point I don't think there's anything we can do except get a skirt and heater, and who knows how fast we can manage that. I'm afraid all of our lines are probably screwed at this point ?

Thank you!! ? I will give those things a try and see if I can find my book as well.

No it wouldn't stop the pump from running if that is all that froze, but they are kind of like a cold conduit to freeze lines in the underbelly. Your situation is as Steve says. Running the furnace more will get more heat into the underbelly. May not be enough to overcome the cold you are in, maybe it will be.
 
Good morning,
I AM in the exact same situation you are in. I am in Tri-Cities and I fill fresh water every week.
Also showered the other night...ran all water in all sinks/shower.
woke up yesterday to zero running water. I put a heater in my 'basement' and a hung a heat gun in the wet bay.
its so warm under there now that I am at a loss too. I am sorry to jump on your post with the same issue...But was surprised that you posted something exactly like what happened to me. if I figure out how to fix it...I will contact you back. I am thinking of just getting a heated hose and hook into city water...at least that's an option for us. :) HAPPY CAMPING!

Hey, wow! Thanks for the reply, and I'm sorry to hear that! Yeah, please do let me know if you figure anything out ? I understand that freezing pipes would likely cause the pump not to work, but in our case, it doesn't even try. Doesn't even attempt to run, not even for a split second. Every time I turn it off and on with the switch at the control panel, I would expect the pump should at least try to run for a quick moment before stopping, but it doesn't. It acts as if it's completely off, has a blown fuse, or maybe a tripped sensor that won't reset, idk...

Our pump is on the upper/living quarters level as well, right under the dinette bench, and I've put a heater on it for good measure and still nothing. The pump itself is definitely not frozen, it's hot as heck in there. The hot water tank heater sounds to be running as normal, so I don't think it's frozen either. We've had our furnace running non stop, so I assumed since we have a "heated underbelly" it shouldn't be too insanely cold down there, but idk really. I wish there was a way to look around inside.

That's a bummer that yours didn't start working after you warmed up the underbelly! That's what I was hoping in our case as well, that everything would magically come back to life once it warms up outside, or maybe if we got a skirt and extra heater below... Some kinda fuse has to be blown, or maybe a remote thermal sensor has it tripped or something along those lines. I dunno. I hope the heated hose works for you! Good luck!

Another weird and concerning note -- I filled the water tank completely full 2 nights ago, right before I showered. The next morning, yesterday, the control panel said 1/3 full. Today, it now reads empty, and we haven't used any water at all since the pump doesn't run. So just to add to our problem, I'm now wondering if the tank or pipe somewhere burst and water has leaked out. Nothing has dripped down to the ground, but maybe if it's cold enough, water could possibly be leaking into the underbelly and freezing down below before it reaches the ground?? I have no idea. But I'm starting to think maybe I should just turn off the hot water tank heaters as well, I don't want the tank to get melted or start a fire from heating while the tank is empty. Ugh.... Our trailer is probably completely screwed after this :(
 
even a heated hose won't stop the city spicket from freezing.
 
gosh I hope running propane will prevent my underbelly from freezing. I think I'm going to have a windchill of zero. My underbelly is closed but I have no skirt underneath.
