Right On that is what I did !!!
Attach my filter to the end,,, with a shut off valve on it !!!
Then you can find another job for your son !!!



PS: May want to make sure the old hose is as clean as posibill !!!

I always use a cut off washing machine hose to fill the FW tank.
Like others mention- stick it in the fill port as far as you can. A little shutoff at the connection between the long hose and the short cut off end helps keep your shoes dry when it's full.

I saw a man trying to fill his tank with just an RV hose with the end still on it.
It burped back and soaked his shirt.
I suggested the cut washing machine hose and he was thankful and said he'd never heard of it!
It's the standard way to fill unless you have a rig that has a built in fill valve so you can fill the FW tank using your city water connection.

Old Washing Machine Hoses would work Great !!!

I tried this method this weekend after filling our tank I tuned on the pump and cold water on the sink, let that run till the overflow water basically slowed to a drip. Unlike last trip where I thought the tank was full but water kept siphoning out the overflow and we made it 3 days before we were out of water this time we made it 4 full days with water to spare and that’s with 2 little kids flushing toilets, baths, showers, and washing dishes multiple times.

You also have to run hot water till it no longer has any air in the lines,,, you can then finish filling the FW tank !!!
I use the outdoor shower,,, where I have removed the Shower head !!!
That is where I always flush water !!!

We have access to our fresh water tank as it is under the bed, pull a few screws and there it is. We did that and saw the tank was collapsing as the water was siphoning out because of the vacuum the siphon created. Freaked us out. So DH cut a hole in the fill tube at the tank so let air in which stopped the siphon but did not re expand the tank. We had to block the vent tubes while adding water (after he repaired the hole he had made) in order to prevent air escaping so the tank could re expand. So now, I NEVER leave the area of those vent tubes while filling and as soon as the first drop of water burps out of the tubes, I shut off the water. No need for caps, just vigilance while filling.

I had the same problem. Once the overflow starts flowing, I turn on the pump and open a faucet. That stops the overflow and tank is full.

Doesn't that behavior (siphoning the tank dry, collapsing the tank) suggest that the vent tube dips too deep into the tank?

The vent tube should come into the top of the tank and stop right there. Then as soon as the water level drops below the end of the tube, the siphoning stops. It shouldn't dip all the way to the bottom of the tank.

Since the tank in question is visible under the bed, I wonder:

• how hard it would be to see how deep it dips into the tank
• how hard it would be to modify the tube so it doesn't dip very deeply.

Wish we would have thought of that!!

For us, the tank began collapsing seemingly immediately as the siphoning began so the level of the water never dropped below the end of the tube. The vent tubes only stick slightly into the tank at the top.

Do not forget to fill the W/H !!!
