Vacuum in Sewer Hose

[Devildog & Norma]

Last week I had our new Challenger 378 out for a couple of days shakedown. All went well. When dumping the Black tank, it did not empty completly. It seemed that a vacuum was created in the hose. This also occured while draining he Grey tank. Any insite would be appreciated. Thanks.

i hope your enjoying your new unit! My suggestion is get rid of the 4" drain hose and purchase one of these sewer solution

I have had mine for almost a year now and would never go back to the old mess of dealing with the standard equipment. The sewer solutions can be purchased online from a variety of stores. The link I provided just happens to be camping world.

The unit just flat works! ..... and your clean-up is so much more effecient and sanitary. Well worth the hundred bucks.

Good luck!

Sounds to me like a clogged vent. Try dumping again and have someone flush the toilet. If it dumps with the toilet open, then it is the vent pipe.

Thanks, I'll give that a try on my next outing,

Sewer Solution! Yes, I have one. Bad planning on my part. It would not allow me to pull the black handle hooked up. So, I used my 3" hose. I have since purchased an extension that will allow it to work. Thanks for the replies.

On the black tank if there is a vacuum you can "Break" it by flushing while dumping.

You need to find out why it's not sucking air from the roof however

Page 2: How are you deciding it's not dumping fully?

Page 3:

I use a clear plastic section (Extension and/or elbow) in my hookup, I can see the "Stuff" and note when it is no longer flowing

I know for a FACT the tank is EMPTY!

Yet the display still shows 2/3 when I push the button

This is normal with the standard sensors

SEE-LEVEL sensors will address this

(If I power wash the sensor wall it will show 1/3 or empty when empty and the 1/3 will be for a short time only)

I fully understand the way and how of this but would prefer not to type it out. suffice to say the "Sensor" is nothing more than a pin, screw or nail that sticks into the tank if it's wet the tank is considered to be "that full" and if there is any "Slime" that sticks to the walls

It's wet


Sewer Solution.. Is not somethind I would buy

Flo-Jet Macerator pump.. IS (in fact I did)
