I bought a Sandpiper 36.5 earlier this year. It being used I am short on some of the manuals that most likely came with it when it was first purchased.
I am having a little trouble figuring out the dump valves. I believe I have a galley holding tank, a grey water holding tank, and a black water holding tank. Someone please correct me if this is wrong. Looking at the dump valves under the camper I see 2 dump valves on small lines that I assume to be the galley and grey water valves. Where I get lost is where the large line, i'm assuming the black water line, comes out of the tank I have a dump valve right under the tank. I also have another dump valve on the same line before it gets to where the grey water lines y's in. I don't understand the purpose of the 2 dump valves on the same line.
Please tell me if I have it all wrong. Any advice or pics would be appreciated.
