Sierra 372lok galley tank

Hi, I have a 2017 Sierra 372lok, all the water from the sinks and shower is going to the gray tank. doesnt seem to be anything going to the galley tank. I was told that only the out door kitchen sink goes to the galley tank? Gray tank fills up quick, are the tanks connected and Im missing something? According to the specs, it has 134 gal gray water tank, says nothing about a galley tank. Any info is greatly appreciated. Thanks in advance!

With the 372LOK floor plan, I'd think the bathroom room and galley are too far apart to share the same tank. Especially with the walk around island. But maybe that depends on the year model. I have the 371REBH and my galley and bathroom have 2 separate tanks. However, I do not have an outside kitchen.

Is your dump valve for the galley tank located at the frame between the water heater and the bunk room?

how many dump handles do you have. there should be 1 for black and either 1 or 2 for gray / galley. if there are two handles for gray / galley you have two separate gray tanks. now you may or may not be able to do something to help. how many sewer hose hooks up do you have? do all tanks drain out through a common sewer hose connection? if so, and if you have two separate gray tanks, you may be able to buy an external valve (valterra makes one) that connects to the common sewer hose connection port and the sewer hose connects to the other side of this valve. if you do this you can close this external valve and open the two valves on the gray tanks. this will allow a connection between the two gray tanks and make them both usable.

I have a 372LOK, had this same question about sizes so i called FR. The bathroom has a 50 gallon gray and black tank. Both handles in the compartment. The kitchen has a 50 gallon tank and has a separate valve on the frame. These all are to the main connection for sewer. The outdoor sink is a 30gallon, with its own drain connection. This valve is also on the frame but in the back. This gray tanks don't add up to 134 so assume the are off a little somewhere.

So if you have a 3rd grey water tank, then I'd assume you need to select tank 2 for galley or gray water in the control panel to check the level on the 3rd tank.

I have a 2018 372lok. I noticed when I got back from camping last weekend after I had dumped all the valves that I can find that it is reading 2/3 full on one of the galley levels. Haven't fully investigated yet but right now I don't really know why it would say that. I only have 2 gray valves to pull. One up front inside the basement and one in back on the frame. I'll post back once I figure it out.

Right next to the rear most sewer connection. They connection is only the outdoor kitchen. Front sewer has two gray valves, one under the water heater and 1 in compartment.

Thank you! Camping World didn’t show me either of the frame mounted valves in our walk around. Then when I called they told me about the rear valve. What a hassle!! Problem solved though.

They didn’t tell us, figured out when kitchen sink was full.

2018 372lok. There is a grey handle in the door beside the black handle. A grey handle on the frame near the front of the mid bunk slide and then a 3rd grey handle behind the tires also on the frame. We were at the beach all last week and now I can’t remember if I dumped the middle tank or not!!! Lol
