Mystery drain valves
Ok pinnacle 36FBTS owners, after two months, finally getting this bad boy ready for the first trip. Pumped water with chlorine into the fresh water tank to sanitize the lines. (Took it from the pool). Ran it through all the lines. But, I was completely wrong about what I assumed is the fresh water tank drain. The drain is located on the drivers side about three quarters to the rear of the coach. It has a stainless colored valve like the shut off valves on the interior. Even with water in the lines, nothing comes out of it. The fresh tank valve appears to be located on the passenger side, towards the rear. Both are labeled low point drains, but the one on the passenger side is obviously the fresh tank drain. I wondered if it was some type of drain for the fridge, but I don't know why it would even have a drain. Also, there is another shut off valve under the island sink. It is currently off and the faucet is working. It is only on one of the lines. Any ideas greatly appreciated.
