312BHTS winterizing Question

**ABPeters** · 10-20-2021, 09:35 PM

Hello,

We have a 2020 GDR 312BHTS, this is our first year to winterize it ourselves. We found the side by side black and grey dump valves on the drivers side of the trailer. Our interior control panel has a grey tank 2 light and button, it’s showing 1/3 full. We cannot find the grey tank 2 dump valve. Can you help?

Thanks,

ABPeters from Ontario, Canada

It would be towards the front. It is on my 2400bh

It is very noticeable plus mine has a sticker on the skirting

Thanks for the reply, you have a “Grey tank 1 and a Grey tank 2”? We found the clearly marked grey tank 1 valve next to the black tank valve, but we cannot find a Grey tank 2. You said near the front… which side of the vehicle drivers or passengers? We appreciate all the help and advice as we aren’t getting much guidance from our dealership.

Yes I have a grey 1 and 2

All sewer actions are on the drivers side

Look along your skirting and there should be a sticker saying grey valve

Hopefully some one with the same model will post. You might not have 2 grey valves. Not every model does but all panel show grey 2 as they use the same panel for all models. As @NB Canada said, all waste gate valve handles are street (driver)side and in plain site or in water docking station. Never hidden away.
