1. Pedal On Dometic Toilet Is Not Working

One of the most common issues when it comes to RV toilets is a faulty pedal. If the pedal is not working properly, the flush on the toilet will not work as well. Sometimes the pedal isn’t working because of debris that is stuck in it. If this is the issue, just clean the debris and that’s it. However, if this is not the problem and your pedal still doesn’t work, then you’ll need to search for the real cause.

Then the problem is most likely related to the link that is placed between the valve and the pedal. However, you don’t need to worry about this issue regarding Dometic toilets because this can be fixed easily. The foot pedal on the toilet has a spring that is connected to the valve. The problem is usually caused by a broken or loose spring.

If you have a problem where the water is leaking out of the base, then this must be fixed in a different way. The best option for this is to buy a new seal for your toilet. Search for a new model in your local market.

3. Black Tank Issue

A Black tank is designed and used to store water that is coming from your RV toilet. Your black tank should be filled with at least a few gallons of water. If you don’t have water in your tank, then the solid will dorp down and stick to the bottom of your tank. Keep in mind that flush water from your RV toilet is not strong enough to remove solids. That way solids will get stuck in the tank and start piling up.

Note! Don’t leave the water valve open because this will cause an even bigger problem.

That way solid will be stacked down in the tank and you’ll also waste a lot of freshwaters. Once the tank is full, the water will stop filling up into the tank. When this happens, the flush will then gather just a small amount of water, and it will stop.

If you opt for a professional, expect that this repair will be really expensive. On the other hand, if you decide to fix this issue by yourself, it will take a lot of your time and patience. To completely clean up your black tank, might take you up to several days. Therefore, be sure to maintain your toilet regularly to avoid this in the future.
