Guide: Buying A Portable RV Dump Tank
Living in an RV supports an active lifestyle. You have to lift, hike, and generally move your body a lot more than sitting at the cubicle all day long. Which is really great, because you can count it as exercise on your little get-away.
However, you will be collecting a lot of waste too, which you have to dump regularly and portable RV dump tanks are the best to work with when you don’t have direct access to full sewer hookups or a composting toilet.
So, would you rather be right down by the beach – or up in the campground crammed in by all the other full hookups?
What is a portable RV dump tank?
When you are using the RV, you create two types of water waste — gray and black water. Gray water comes from the sink, shower, and the basin. On the other hand, black water is collected from the toilet. It holds both liquid and solid matter. It’s easy to attach the tank to your RV’s black water waste valve to a tank on wheels. Now you have what’s called a “portable black water tank.” It’s just a nicer way to say all those POOP words that are some much fun to say.
When it is full, detach it, and go to the dump station to empty the contents. The stations have hand sprays that you can use to clean the insides. Pretty simple right?
It is a convenient product and very easy to use. You can either use one tank for both types of water only two separate ones. We find using two tanks easier because you can use the gray water to clean out the black water tank after you empty it. That way, you save a lot of water. The only downside is that you will have to tow two tanks instead of one.
How to use the dump tank?
- Wear gloves because your hands are going to get very dirty.
- Attach the portable tank’s sewer hose to the RV holding tank.
- Connect the gray water tank to the gray water valve and likewise for black water.
- Close the valve when the tank is full and tow it towards the dump station.
- Empty it and follow the cleaning process as mentioned by the manufacturer.
- Continue flushing the tank until no more wastewater or solid comes out of it.
In case, the portable tank leaks when you are towing it, you might need a replacement because it is close to breaking.
How to deep clean the portable tank?
You will need to deep clean the portable tank every three months. Add a mix of bleach and water to the RV holding tank and empty it into the portable tank for 24 hours. Drain out the water completely and wash it with fresh water until the bleach smell goes away. Keep the tank open to air it as it reduces the bleach smell.
You can add a few drops of treatment chemical to the tank before you connect it to your RV as it masks the foul smell of the waste contents it will hold until you clean it again.
Benefits of using a Portable Dump Tank
Dealing with waste is the only unpleasant part of the living in an RV home. Other than that, it is full of adventures, meeting new people, and eating a lot of food. Here are three advantages of using a portable RV dump tank:
Limit how much water you use by using a small RV dump tank. You can measure how much water you use depending on the number of trips you need to take daily to the washroom. Also, many manufacturers make tanks using eco-friendly material. Make sure you buy only from such brands.
2. Easy to use
You don’t want to not have a washroom in your RV and wait in line at a public restroom for 20 minutes before your turn. It is as hygienic as having your personal toilet. You have to dump it once a week but that’s all the work you need to do.
3. Convenient cleaning process
Some dump stations have narrow openings, which means you can’t drive your RV close to the dump hole. When you have a portable dumping tank, you can detach it from the RV and pull it towards the hole.
Things to remember while buying the tank
1. Choice of material
Invest in a good quality polyethylene or plastic tank, which will last you for a lifetime. It is also lightweight compared to metal tanks, which are also subject to cracking under pressure.
2. Number of tanks
Dumping tanks are either made for both types of water or separately for gray and black water. Read the product details before you purchase. When you use one tank for both, you will have to dump often. Using two tanks is a more eco-friendly option as you can use gray water to clean the black water tank.
Portable tanks come with two wheels or four wheels. The latter option is easy to pull but it is the wheel material that matters the most here. Rubber is the best choice as it is durable and easy to clean.
4. Trip length
If you aren’t a full-time RV user, you can purchase a 30-gallon tank, which is sufficient for a three-night trip for two people. If you are living full-time, purchase anything that has a holding capacity of more than 40 gallons.
