Reasons and Solutions for Black Tank Flush Not Working

1. Spray Nozzle Is Clogged

One of the most useful things in an RV or motorhome is its bathroom. This is exactly why the flush not working on your vehicle can be so annoying to deal with. Although, you should understand that tons of things can cause this issue. This is why it is important that you carefully troubleshoot your toilet to find the exact reason for your problem.

Talking about this, you can start with the most common culprit which is having a clog in your spray nozzle. This usually happens when you only flush the tank on your toilet when it is nearly full. Considering this, one option is that you manually flush the tank. Although, this requires a lot of effort and you will have to ask others to help you.

This is why it is better that you go with the second solution. You can start by adding clean water to your toilet bowl. Now you should add in a small amount of toilet tank cleaner. There are tons of companies that manufacture this product and you can use any of these as long as the brand is reliable. On the other hand, if you do not have access to a tank cleaner then you can also add a solution of soap.

Once this has been added, you will have to wait for 24 hours so that the soap can break the solids clogging your spray nozzle. If you do not have as much time then make sure that the solution sits for at least 12 hours. After the debris has loosened up, flushing the toiler should now work. You will notice that water flows out without any problems. Though, make sure that you make a habit of flushing to avoid running into the same issue again.

2. Flush Your Toilet Properly

One of the most common reasons why many people get this issue is that they are not flushing their toilets properly. Keep in mind that the toilets in your motorhome usually work differently than your toilets at home. Considering this, some people just push down the pedal completely.

However, you have to first hold down half of the pedal so that water can start entering the bowl. Once you think that enough water has been added to the bowl, pushing down the pedal completely will let out all of this. Using this two-step process will ensure that your toilet runs without getting any clogs in it. Additionally, one recommendation is that you use a flush wand to unclog your black tank if required.

3. Problems with Valve

Another common reason why you can start getting problems with the black tank flush on your RV not working is that your valves have some issues. These are quite common but fixing the problem on your own can be quite difficult. Considering this, if your valves have any issues with them then you should contact your vehicle’s customer service.

Your dealer should be able to look into your problem and then provide you with a solution. If necessary then they will most likely ask you to bring in your vehicle for replacements or repairs. Additionally, this should be covered by the warranty in most cases which saves you a lot of money.
