As a full time RVer, it’s vital that you properly maintain your RV waste water systems, not only because you want to avoid disgusting odors, but also because prevention is the best defense. As a rule, it’s always better to avoid a problem than to have to deal with it later. There’s quite a bit of misinformation out there regarding the best ways to treat your tank, so we’ve developed this easy-to-follow, step-by-step guide that will teach you how to effectively treat your black tank and gray tank.
Repeat these steps each time you dump your tank. To ensure that your waste is being properly digested and odors controlled, treat your black water holding tank, following these instructions, after each dump. You will only need to use 2 ounces of RV Digest-It per treatment after the initial treatment.
Everyone has differing ideas on how to properly treat a gray water holding tank. For full time RVers, the method you ultimately choose is your decision, and it should be based on how you routinely camp. What follows are our recommendations when using RV Digest-It.
Before we get started, full timers who camp with full hook ups should know that we recommend keeping your gray valve open with a trap in the hose to prevent sewer gas from backing up inside your RV. We know this goes against the grain for some of you who’ve been properly trained to always keep your black valve closed, but the reality is that your gray tank should be treated differently than your black tank.
Important note: In some states, you are required to keep your waste hose off the ground. This is sometimes punishable by law and can cost unsuspecting RVers their hard-earned money. Please make sure you are aware of all local laws and regulations!
Because we use our gray tanks more than our black tanks, they tend to fill up faster. If you routinely keep your gray valve closed, you will have to dump very regularly—often every day! This means more work for you and more expense if you are treating your gray tanks with RV Digest-It after each dump. This is simply not necessary if you’re camping on full hook ups.
Besides convenience and cost, we also suggest keeping your gray valve open, because grease (from food waste, soap, shampoo, etc.) will likely end up in your gray tank. If you allow water to accumulate in your tank, this grease will end up coating the walls and bottom of your tank and will eventually lead to sensor problems and odors. By leaving your valve open, the gray water, grease, and light residue will run out of your tank naturally.
The majority of the waste going down your sink, shower, or dishwasher drains should be liquid. Ultimately, your goal is to never allow solids into your gray tank; therefore, solid waste (i.e., clogs) shouldn’t really be a problem. If you don’t already use one, a good sink strainer is crucial to ensuring that only liquids go down your drains.
Some will argue that it’s not a good idea to keep your gray valve open, because solids may back up, causing a clog. Also, these people argue that solids may coat your sensors, causing them to misread. However, these concerns shouldn’t be an issue if you are ensuring that no solids go down your drains and end up in the gray tank. Furthermore, by treating your gray tank once per week, you can help eliminate any grease buildup on the walls, in the lines, or on the bottom of the tank.
It is also very important that you put a “trap” in your discharge line. This will prevent foul smelling, dangerous sewer gases from backing-up into your unit. A trap is made by creating a dip or kink in the line (as mentioned above). If you forget to do this, you will know it pretty quickly, as your unit will fill up with foul smells from the sewer!

Even if you allow only liquids into your gray tank, however, you will still accumulate grease, soap, and residue in the tank bottom and lines. As mentioned, grease can eventually lead to foul tank odors and cause sensors to misread. With this in mind, it’s very important that you follow the following steps to make sure that your tanks continue to operate properly and that you don’t get odors in your RV.
Important: it’s crucial that you make a 'trap' in your sewer hose to keep dangerous and disgusting sewer gases from backing up into your RV!
If you are dry camping (i.e., boondocking) full time and don’t have access to full hook-ups, it’s crucial that you use a waste treatment product to control odors and help keep your sensors in proper working order.
Important note: As we mentioned before, make sure no solids get into your RV gray tank. The waste going down your drain should only be liquid waste. Solid waste in your gray tank will lead to clogs and misreading sensors. If you don’t already use one, a good sink strainer is crucial to ensuring that only liquids go down your drains.
