Hi Team -- I just bought this 2022 Pioneer DS320 and can't locate the siphon hose to add antifreeze -- any help would be greatly appreciated

The siphon hose is located on the water pump, it is on the inlet side. Sometimes the water pumps are installed in various locations, depending on the model of the rig. On our Road Warrior, the water pump is close to the water inlet valve. Some individuals have found the pump in cabinets, under drawers, etc...

Thanks -- would it generally be under the sink? Is it a possibility it doesn't have one or does all trailers have one

On our rig the water pump is near the water inlet valve, behind the basement wall. I have to take a wall down to reach it.
Can you post some pictures of the basement area?
