3 Gray Water Tank Cleaning Tips

A Gray water tank collects soapy waste water and food debris from kitchen sinks. In RVs, this waste water is stored temporarily until it can be dumped into a municipal sewer or treatment plant. In domestic gray water systems, the waste water stream is rendered in a grease trap and diverted to fertilize garden beds. In either application, clean the gray water tank regularly to prevent bacterial infestation and noxious odors.

1. Use Cleaning Chemicals 

There are multiple chemical solutions that can loosen residues in the gray water tank. Water softener, anti-foaming solution, and baking soda are all options. The best choice depends on the terminal dumping point. Some chemicals are harmful to plants and beneficial septic system bacteria.

2. Agitate Waste Water Tank

Stirring up the contents of the gray water tank will loosen food particles and soap scum. If the tank is in an RV, you can just drive down an empty highway. For home systems, you may have to dig up the tank.

3. Dump a Full Tank

Emptying a full tank provides enough pressure to clear out all debris. Flush the tank out with fresh water if possible. Add new septic enzymes afterward.
