anyone have a problem with the second tank filling?

Anyone having problems filling water tanks on toyhaulers?

Any tricks to doing this? It seems like I can oly get my tanks about half full.

 

Maybe open a faucet to purge the air as you fill?

 

I have a gate valve between the two tanks. The water fill dumps water into the aft tank, gate valve has to be open to fill the front tank.

 

I bet somebody might be able to help you if you told us what type and model toy hauler you have.

 

I had to reroute, zip tie down the filler tube. It was looped up and obviously the water would just flow back out the tube. Once I secured the filler tube with a down hill flow it's fine.

Good luck.

 

Ditto for me. I have a 2007 WW FS2300. I usually only fill one 50 gal on most trips. If we're going to be gone a week I will pull the valve and fill 100 gal.

 

I always pull one side of the trailer up on boards to make one side of the trailor higher than the other. This helps with filling the water tanks to FULL capacity and also helps when dumping waste from the grey and black tanks

 

For some reason, the vent like gets water in it during the fill process. I have to blow air through the vent tube EVERY TIME I fill my water tanks.

I've had the hose re-routed twice, but this is the only way I can get the tank full.

Totally frustrating.
But it might work for you.

 

It doesn't help that the vent tube on these is the size of a pencil. Trickle filling sucks!!

 

You should have a drain valve on each tank. Open the valve furthest away from the filler neck (it's the rear tank for me) and start filling. Once water starts to come out of the drain, close the valve and keep filling.

I think that the fact that the tanks are baffled, and connected by small hose makes back pressure in the rear tank while filling causing the first tank to fill quickly while very little gets into the rear tank.

 

fill it slower, helps with mine.
