Laredo 301rl: which valve is the blackwater valve?

[BooRadley]

I was recently gifted with a Laredo 301rl. 2013 model, I think. I am also new to RVs.

Anyways, there are no labels distinguishing the blackwater valve from the greywater valves. The manual I have also doesn't give this information.

It might be a dumb question, but before I make some terrible mistake, I thought I should ask someone who knows. There are three valves. Left to right, which one is for the blackwater tank on the Laredo 301RL? Anyone know?

Thanks.

Large pipe is for Black water drain, smaller pipes are for Gray water, if you can see them as they enter the main drain pipe. 2 1/2" is the Black tank and the 1 1/2 are the Gray, if I remember right. Keep watching feedback as you will get someone who has your trailer to give better information.

BooRadley, Howdy;

You need to make 1 possiably 2 trips. First to get a clear extension for the
drain line. http://www.valterra.com/RV/rv-main.htm
Scroll down to the next to the last items.
Then you will need to find an RV dump site to dump, one at a time and
you should be able to see which is which... easy-peezy.
