Waste Tank-Management Tips — Back to Basics

RV Hooked up at dumping station to dump wastewater

RV holding tanks — some management basics.

Here are some waste tank management tips for those who may be relatively new to RVing or to extended campground stays. This will deal strictly with using the standard 3-inch gravity hose. The optional macerator type Sani-Con will be covered in a separate post at a later date.

Upon arrival at your campsite, presuming the waste tanks are empty, hook up the sewer hose and open the gray water gate valve. This generally can be identified by a label or observing the smaller feed pipe behind the slide valve. This valve will be left in the open position.

As time passes you will notice that your tank monitor located in the coach will indicate zero change to the gray level while the black tank level increases daily.

When the monitor shows the black tank has reached about ¾ full, go out and close the gray tank valve. With the normal use of the household water, the gray tank level will rise shortly. When there is about a quarter of a tank or so, you can now empty the waste tanks with the following procedure.

In time, the tank’s level sensors may become affected by grease or food waste in the gray, and solid and paper waste in the black. This may result in inaccurate tank level readings.

The following tips may prove beneficial in correcting this issue.

So, remember that the black tank is always dumped first and then closed prior to dumping the gray. Additionally, you should pour a little water in the sink and shower drains after layups or after travelling. Full drain traps will prevent odor from the gray water tank. This routine will keep your RV holding tanks in good shape.

Well, that’s just some basics.  Hope it is of help to some. Find all the accessories you need at Camping World.
