2014 eagle 315rlts sewer hose check valve...

Hey all,

i got this trailer last fall, so i have yet to use it. I had to do some repairs/maintenance items to it upon reception. I went through the process of flushing the black water tank via wand down the toilet and managed to loosen quite a bit apparently... When i took it to the dump station to empty the tanks, i tried to use the black tank flush line... However it would not take any water what-so-ever. I honestly think the check valve is installed in reverse! I'm not about to suck on the inlet to find out lol!
Anyhow, does anyone know where the sewer flush check valve is located on these rigs? I have had previous campers where it was under the bathroom sink....but no on this one...

Thanks in advance!

There is no check valve that i know of, but a vacuum breaker usually located in the bathroom under the sink. (Model specific.) They are made of plastic and usually fail and leave water on the floor. most of these end up replaced by ether removing the old one and putting a screw on hose type in the convenience center or just replacing it with a good brass one under the sink. You can find it as the pex line is usually colored white. but as you stated it could of been removed.

If the original owner never used it, or rarily, they have been know to clog.
