RV Portable Waste Tank Reviews
It is important to choose the right portable waste tank to avoid any inconvenience in your trip.
For instance, there is a difference between 2 wheeler and 4 wheeler versions of the RV sewer tank. While the 2 wheeler only has wheels on the back, the 4 wheeler has wheels on all 4 sides. A 2 wheeler is a more difficult tank to operate. It not only demands more strength but is also harsh on your back. You will find the 4 wheeler tank easier to operate on almost all surfaces.
The bright side of choosing a 2 wheeler tank is the low cost. While the 2 wheeler might be easy on your pocket, you will realize over time that the actual value for money is received from the 4 wheeler portable RV septic tanks. The extra money saves you from the backache of dragging extremely heavy water tanks.

We have made your job easier by providing the RV portable waste tank reviews by considering multiple factors.

Q. How do you replace an RV waste valve?
The first step while replacing the waste valve is to determine the need for replacement. Some valves can be repaired too. However, replacing it is a better option as it saves a lot of time and effort. Next, you should rinse the valve and tanks twice to get rid of all the waste.
Step 1 – Remove the old valve
The valve is held together using two flanges. It is held using 4 nuts and bolts. Unscrew these to release the valve. You may need to twist the valve or apply pressure to pull the valve out.
Step 2 – Cleaning
The next step is to clean both the flanges properly. Then apply a light coating of grease on the new valve and the pipe.
Step 3 – Replace
Replace the rubber gaskets that hold the valve. Place new ones on the valve and then slide it between the flanges.
Step 4 – Secure the valve
Secure the valve using stainless steel nuts and bolts. However, avoid overtightening the bolts, which can cause trouble in the future.
Q. Can you hook your RV to the septic tank?
Yes, you can connect your RV to the septic tank. However, there are some words of cautions to follow to avoid any mess.
Firstly, make sure to use an elbow-shaped hose for avoiding splashes or messes. Moreover, do not overload the septic tank too quickly. Adding too much waste at once can cause a blockage in the system. It will take a lot of time to unclog it.
Do not use chemicals in your black water tank that may disrupt the breaking down process of the waste and affect the tank’s natural ecosystem.
Lastly, make sure that you are on the right side of the baffle while dumping from the access point. It is the one far away from the outlet port.
Q. How do RV holding tank sensors work?
RV Holding tank sensors use a circuit system. The sensors are installed vertically through the holding tank. Once the level rises to a particular level, the water conducts a small charge. This enables the completion of the circuit, which is indicated through a light on the indicator panel.
Q. How do I choose the right size of the RV extendable holding tank?
There are certain factors to consider while selecting the right capacity of the extendable portable RV holding tank.
The number of people going on the trip is an important factor. Another important consideration is the length of the trip. More the number, the higher the capacity for the holding tank.
You might want to go ahead with the highest capacity. However, there are a few drawbacks to it. A bigger tank adds to the cost and increases the weight in the RV.
Also, consider the capacity of the black water storage tank. Make sure that the portable tank has a capacity a little higher to the black water tank, to avoid any spillage while dumping.
