Travel Trailer in Cold Weather

Hey guys. Iím an RV newbie (stationary full timer) and I could use some tips for my first winter in my TT. Even though Iím in Alabama, itís been cold here lately. My water has froze twice (20 - 30s) and Iím frustrated. I have a heat taped hose and I leave my water dripping. Iíve never used my freshwater tank and Iím on full hook ups. Should I just unhook the city water during freezing? I came home today to a busted water filter outside and water going everywhere. Iím grateful itís all good inside, just donít want any expensive messes. Also, I emptied my black and grey tanks and poured rv antifreeze in to keep from freezing. Someone said to leave the grey tank open, so Iíve done that.

Below freezing temps are not too common, but it happens for a few weeks. Any advice is appreciated!

If you have heat tape on your hose and faucet standpipe you shouldn't freeze up at those temps. If there's even a little bit of pipe uncovered it can freeze.

I'd suggest just unhooking your water hose and draining it whenever it's going to freeze.

I don't know what part of Alabama you're in but it can get pretty cold north of Montgomery for a few days. Now down here where we are we don't get much cold.

Thanks, I will do that. Itís not worth the hassle to worry about a flood while Iím at work.

The filter wasnít covered, so thatís probably what happened. Iím just a little north of Birmingham.

Is the heat tape working? If so, the hose shouldn't have froze at the temps. you described.
You should also never leave the RV for any length of time without turning off the water supply at the spigot/standpipe.
On your 28RLSS, is it advertised as having an enclosed & heated underbelly? If so, when your furnace is running, it sends some ducted heat into the underbelly and keeps the tanks warm.....to a point. In this case you could use your FW tank & pump and leave the hose disconnected and drained.
X2 - leave your grey/galley tanks open.

Heat tape is good. I think I need to better insulate and wrap where the city water comes in. Good thing is, itíll be warm the next week. Thanks for the reply.

Yes, unhook from your city water connection (both ends) and put enough water in your fresh water tank to get you through the cold spell. Empty out your hose and put it away.

This is part of my procedure for cold temps (last night was 19 here). Drop water connection, add water to fresh tank, heat on, water heater on.

The gray and black tanks will be fine. I don't leave the valves open. You can pour a little AF in if it makes you feel better.

When we find ourselves in Cold temps, we fill up our tanks. We have heat pads on our tanks so we use them to keep them warm. We don't use them if we do not have full hookups because heating all three tanks along with your furnace will blow through your batteries quickly. When we don't have full hookups, we drop some antifreeze in the black and gray water and only use the heat pads for the fresh water.

Why do so many RVers recommend leaving grey water tank drain valves open when you are connected to the sewer line?? This provides a direct path from grey water tanks to the RV Park sewer lines that are bound to contain dangerous gases like methane, not to mention bad smells. Those bad gases and smells can easily percolate up into your grey water tanks and into your RV with potentially serious consequences. Am I missing something??

Leave gray tank drain valve open during winter

You should leave the gray tank valve open in freezing weather. The tank itself is High-Density PolyEthylene (HDPE) which is flexible enough to withstand the expansion of freezing water.

But the lowest point in the system, which fills first, is the flimsy ABS/foam-core plumbing from the tank to the dump valve. That fills with water, freezes and splits the pipe. It's a nuisance to find ABS pipe fittings and cement and make up the replacements after two separate pipe segments have split. Ask me how I know.

From November to April we leave the gray drain valve open and the Blue Boy connected to it. Especially since we leave a dehumidifier running in the shower year round. In the summer, of course, we close the gray drain valve and drain it after the black tank to flush the hose.
