Help winterizing

I am trying to put rv antifreeze in the fresh water tank as a step in winterizing. Using a hose and funnel in the gravity fill port, I tried pouring antifreeze in but it just ran back out. Do I need to get a longer hose or something? It seems like the "tube" goes straight back for a good distance. We've got cold weather coming soon so I need to get this done. Any suggestions? TIA for any pointers you can give.

(It's a 1997 Fleetwood Bounder 35U)

I dont think you really need to put RV antifreeze in the fresh water tank. Just open the tank drain and let all the water drain out.

If you put rv antifreeze into your fresh water tank it will take hundreds of gallons of flushing to get the antifreeze out. Your water will be almost unusable. It will always be foamy and stink like rv antifreeze.

Is there somewhere in your owners manual that says to put rv antifreeze into the fresh water tank?

I agree with AKIQPilot but if you must put in the RV antifreeze are you sure your RV isn't tilted towards the fill port or maybe try tilting your RV away from the fill port.

Donít put antifreeze in the fresh water tank.

Just pull the drain plugs and let it empty out on itís own. Thereís lots of room for any expansion of any water left behind. By pass the water heater, and drain it too.

Just antifreeze the entire system using the pump to flush it out of every tap inside and out. Shower head, and make sure the toilet runs pink from itís input lines.

I am following the directions in the owner's manual which says to pour approximately 5 gallons of RV antifreeze in the fresh water tank and then turn the water pump on and open each faucet until the antifreeze runs through. We have already drained all the tanks and lines and bypassed the water heater.

kenandterry, how do I use the pump to flush the antifreeze out of the taps if I don't put the antifreeze in the tank?

In case it's not apparent, I am a total newb at this and I appreciate any and all help I can get!

We actually do put RV antifreeze in our fresh water tank to winterize, but we NEVER drink from that tank. When readying for use again, we just drain it, fill it, and drain it again, and we can't smell it. But, like I said, we never drink from the tank.

I think this video (https://youtu.be/8Bo1VPGGiFo) will show you how to use your pump to pump direct from the bottle without putting it in your tank.

Make a hose to connect to the suction side of your water pump. Disconnect the hose coming from your tank at the inlet or suction side of the pump, connect the hose you made up to the pump. Place the end of the hose down in a jug of antifreeze and pump it through the system. (U-TUBE it) no antifreeze in the fresh water tank will be needed.

I agree with others....you DO NOT have to put pink stuff in fresh tank. Watch several good YouTubes and your good to go....easy peasy!!!

Putting anti-freeze in your fresh water holding tank is a big mistake. Open the low point drains and that's about all you need to do. If you use anti-freeze in the tank, next year you'll have a heck of a time getting it out. The residual will be in there for a long time.

Exactly. RV antifreeze is nasty. It stinks. It foams. It will make everything smell and taste horrible for a long long time even if you donít drink the water, ie shower, icemaker, brushing teeth, washing clothes, washing dishes, etc.

Heck I spend at least half an hour flushing it out of just the lines and I donít put any in the holding tank or water heater.

I drain everything: fresh water tank, hot water heater, low point drains. Then I suck the AF in until it runs pink in every faucet as well as the toilet. Once that's done I hook up 40 psi of compressed air to the water inlet and blow all the AF out of the lines into a bucket. I pour the bucket into the toilet and leave it sit in the bowl all winter. It keeps the toilet seal damp.

Also only use about a 2' hose. Don't expect to pick up from the ground.
You'll only need 2 gal. Be SURE it's RV antifreeze.

Us northerners have a valve and open ended suction hose already installed on the input side of our 12 volt pumps. We stick the hose in a 1 gallon bottle if anti-freeze and open each tap. We forget not all RVs come that way.
Some RV manufactures save money and don't install the valve and hose. They may have put the pump in an inaccessible place. The alternative to a valve and suction hose is the dump lots of anti-freeze in the fresh tank and pump it out. This is the worst solution. The anti-freeze gets diluted in the fresh tank because you can never get all the water out. You need 5 gallons because the pump can't reach the anti-freeze at the bottom of the tank.
Best to get a valve and open ended hose installed yourself or by your dealer. You will need a lot less anti-freeze.
Regards,
Paul Bristol
