If you’re an RV owner, then you know that keeping your black tank clean is essential for preventing nasty odors from wafting through your vehicle. One of the most good ways to clean your black tank is by using a flush check valve. Here’s a look at a flush check valve and why you need one.

Black Tank Flush Check Valve
Maintaining a clean and odor-free RV black tank is essential for a pleasant camping experience. One way to ensure your black tank stays clean is to install a black tank flush check valve. This valve allows you to hook up a hose to your RV’s black tank and flush it with water.
The Valve prevents sewage from back splashing out of the tank and has a screen that catches debris before entering the tank. As a result, a black tank flush check valve can help you to keep your black tank clean and free of odors.
Does A Black Tank Flush Have A Check Valve?
There are a couple of things that need to happen for a black tank flush to work correctly. First, you must hook a hose to the inlet valve and ensure the water is turned on. Then, the rinsers spray the water in different directions, cleaning out the black tank. The important thing is to have around 40 psi of water going through the hose.
If everything is working correctly, the black tank should be flushed clean. However, the black tank flush may not work correctly if you don’t have enough pressure or if the inlet valve is blocked. In that case, you may need to call a professional to look at your RV’s black tank flush system.
Where Is The Black Tank Flush Valve Located?
If you’re wondering where your black tank flush valve is located, it’s most likely in a cabinet inside your RV. The valve is usually installed above the connection for an external hose, which helps prevent siphoning.
This is an important safety feature, as it can help to prevent contaminated water from entering your RV’s water supply. If you’re having trouble finding the valve, try asking your RV dealer or a qualified technician for assistance.
How Do You Use A Black Tank Flush Valve?
Most people don’t give much thought to their black tank flush valve until they encounter a problem with it. Then, it can seem like the daunting task. However, using a black tank flush valve is quite simple. The first step is to turn off water in RV. Then, disconnect the hose from the flush valve and remove any debris blocking the opening.
Next, connect your garden hose to the flush valve and turn on the water. Run the water through the valve until it is clear of any debris. Finally, disconnect the hose and turn on the water to your RV.
What Does A RV Vacuum Breaker Check Valve Do?
When a toilet is flushed, the water in the bowl is forced downward through the drain line. This downward flow of water creates a vacuum, which can cause contaminated water to be drawn back into the clean water supply.
An RV vacuum breaker check valve is installed in the plumbing line to prevent this from happening. The valve allows water to flow freely in one direction but closes automatically if there is any attempt to reverse the flow of water. As a result, the vacuum is broken, and contaminated water is prevented from entering the clean water supply.
Why Is My Black Tank Flush Not Working?
If your black tank flush isn’t working, there are a few things you can check. First, ensure the water is turned on, and there is enough pressure. Next, check the inlet valve to see if it is blocked. If the valve is blocked, you may need to call a professional to clear it.
Clogged spray nozzle
Clogged spray nozzle heads can prevent your black tank flush from working correctly. You can clean the nozzle heads by removing them and soaking them in vinegar overnight. Finally, ensure the hose is connected correctly and there are no leaks. If you follow these simple steps, you should be able to get your black tank flush working correctly again.
Not flushing the toilet correctly.
If you don’t flush the toilet correctly, it can cause problems with your black tank flush. Toilet paper and solid waste should be flushed down the toilet, while liquids should be dumped in a sink or shower.
Dumping liquids into the toilet can cause problems because they can seep through the valve and into the black tank. This can lead to odors and clogs. Toilet paper can also cause problems if it isn’t flushed correctly.
If it doesn’t break down properly, it can cause clogs in the hose or the black tank flush valve. As a result, it’s important to be mindful of what you’re flushing down the toilet.
No water previously in the black tank
If there was no water previously in the black tank, the newly added water could cause problems. The new water can cause the solids to float to the top and create a sludge layer.
This sludge can prevent the black tank flush from working properly. To fix this problem, you can add a few gallons of water to the black tank before using the black tank flush.
The tank contents have been sitting too long.
If the contents of the black tank have been sitting for too long, they can harden and become difficult to remove. In this case, adding a cleaner to the tank is important before using the black tank flush.
These cleaners will help break down the waste and make it easier to flush out of the system. After adding a cleaner, run plenty of water through the tank to flush out all the waste.
Final Words
RV black tank flush check valves are necessary for any RV sewer system. They keep your tanks clean and free of debris, saving you time and money in the long run. We recommend using a check valve on each line entering and leaving your RV’s black tank to ensure the best possible performance from your sewer system.2
