Keeping holding tanks clean and fresh smelling is easy with these effective products in petite packages

 

We all love to think about our next RV journey. Discovering new places, meeting friends, making memories that can last a lifetime. The one thing we don’t like to think about, however, are holding tanks. We don’t want to imagine what’s in them, and we certainly don’t relish the thought of emptying them. Unpleasant as they may seem, they are a necessary evil that allows us the freedom to travel anywhere and always have a bathroom along for the journey, which is a great convenience. And, the fact is, holding tanks really aren’t a big deal if you use the proper chemicals and practice the correct dumping and flushing procedures.

Most large travel trailers and fifth-wheels have commensurately sized holding tanks and storage compartments that can easily accommodate your dumping hardware and chemical of choice. But what about smaller trailers and campers? Sometimes exterior storage is at a premium, limiting the size of the sanitation products we can bring along. So, we’re presenting some of the most popular holding-tank products — described in each company’s own words — that are available in small bottles, packets and the latest development, the drop-in (aka toss-in). Of course, all of these companies offer larger containers for bigger trailers, so make sure to visit their websites to see what is available for your application.


How to Do It

 

 

 

Dumping Basics


Dumping an RV’s holding tanks seems like a pretty simple process — and it is, if you know how to do it properly. The trouble is, many new RVers aren’t shown the basics from the beginning, and some learn the hard way that incorrect practices can result in some rather unpleasant surprises. To prevent you from becoming another amusing story around the campfire, here are some helpful tips:

  • • Buy a box of disposable gloves and keep them, along with a bottle of hand sanitizer and some paper towels, in the utility bay.
  • • When using the toilet, it’s tempting to conserve water, but too little can cause buildup in the tank, making it hard to empty.
  • • When hooked up to the sewer, it’s OK to leave the gray valve open, but not the black. Wait until this tank is around half full, then go outside and pull the handle. Leaving the valve open allows liquids to drain away, leaving solids behind. Make sure the gray tank valve is closed before opening the black valve handle.
  • • If you don’t have a black-tank flush, keep a five-gallon bucket on hand. After dumping the black tank, open the toilet valve and dump a bucketful of water down — it’s a lot more sanitary than dragging the dump station hose through your rig or running it into a window. Repeat the process a couple of times if you have a larger holding tank. It doesn’t have to be full — just enough to rinse away leftover stuff at the bottom of the tank.
  • • When you’re finished, put about a gallon of water in the tank and add some toilet treatment.

 

 

 

 

 

 

 

dumping-01
1. Get yourself a good hose with a 90-degree, threaded fitting like this one from Valterra. It will work with a variety of sewer ports, and even if the one you’re using isn’t threaded, having this fitting will prevent the hose from coming out when you dump and keep odor to a minimum.


dumping-02
2. It doesn’t really matter which end of the sewer hose you connect first. For our purposes, we started at the sewer port. Before connecting the hose, make sure the fitting on the end is properly attached, then turn it clockwise into the elbow until the pegs on the hose fitting are completely seated in the barbs on the elbow. As you can see here, the hose is not completely locked into the fitting yet.


dumping-03
3. Remove the sewer cap from the RV and attach the other end of the hose. You’ll note that we use a clear fitting, which may sound gross, but it allows you to see when the tank is rinsed completely clean, as it is here. If you’re hooked up at an RV park, open the black-tank valve only after making sure the gray-water valve is closed. Once empty, close the black-tank valve and either dump your bucket(s) of water down the toilet, or attach the dump station hose to the black-tank flush port, and turn it on. It’s a good idea to leave the black-tank valve open during flushing to prevent the tank from getting full and possibly rupturing. However, as long as you stay with the rig while running the water, it’s OK to close the black-tank valve, and open it after a minute or so (depending on the size of your holding tank, of course). Repeat this step twice.


dumping-04
4. Close the black-tank valve, then open the gray-tank valve. Since gray water is primarily soapy water from the sinks and shower, it helps to further clean the inside of the sewer hose.


dumping-05
5. Some dump stations may have a curb around the sewer port, which can make dumping a challenge. Keep a sewer hose support like this one in your storage compartment.


dumping-06
6. When you’re all done, wash your sewer hose thoroughly, and don’t put the water hose inside — it’s bad form. Hold the sewer hose up straight after rinsing to make sure it has no more liquid in it, then pull it from the port and thoroughly rinse the dump station with water so it is clean and ready for the next person.
