Dump valves--Which is what?

[billt01]

On my Solaire 317 BHSK i have two dump valves, one to the left and right of the main line. I was told that the one on the right is for the grey (smaller diameter) and the one on the left was for the black (larger diameter--for solids I would assume). However I have located two additional valves further to the left of the left "main" that are located under the TT with no label on them that feed into the larger (one on the left) diameter pipe.

Can anyone tell me what are for...they were open from the factory.

There is nothing in the manual that references this.

Post a pic to better understand what you have underneath if possible...
your unit specs a 76gal grey tank which typically is split into two tanks, that means two pull handles besides the one pull handle for the black tank.
The freshwater tank is located under the bedroom @ front of TT but should have a ball valve that empties water directly onto the ground & not through the main pipe.

I am only assuming here, but I would have to guess that they are additional valves for the black and gray tank. The idea is those handles are operating valves enclosed in the underbelly to keep the pipes from freezing. The handles on the outside would be for normal summer use and to ease in the dumping process...

Just my assumption! Don't hurt me if I am wrong!

I will post some pics when I get home...
