What is an RV gray water tank?

[Johnny]

It holds wastewater on an RV. Introduction to gray water tank: In English, it's called graywater, which literally translates to gray water. It refers to domestic water used in RVs for activities like washing and dishwashing, generally discharged through pipes connected to the tank. The gray water tank typically holds around 40 to 50 liters, and most RVs come with a water level gauge to monitor the tank's fill level. When it's nearly full, you need to find a place to discharge it. Campgrounds abroad are more developed, with designated areas for wastewater disposal, while domestic campgrounds are less equipped in this regard. Currently, many RV enthusiasts usually discharge the gray water into sewers or ditches via pipes. Extension: RV water systems mainly consist of fresh water tanks, gray water tanks, and black water tanks, covering both water supply and drainage. The fresh water tank is used to store clean domestic water, with capacities ranging from 40 to 100 liters depending on the RV model, and some large RVs may have tanks up to 180 liters. The black water tank specifically refers to the sewage discharged from the toilet.
