The problem with RV is that it has a compact space. So, if your toilet has a foul odor, it quickly spreads through your entire RV.

The problem with Dometic 320 toilet is that sometimes its rubber seal doesn’t work correctly.

As a result, water from the black tank can spread through your commode. It will eventually spread the odor to your entire RV.

So, it’s a big negative point for an RV toilet. However, with frequent maintenance, you can overcome this problem.

  • Water Leakage

Another big problem with Dometic 320 Toilet is the water leakage. Sometimes water starts leaking from the base of the commode.

It happens because of a faulty flange. This round shape rubber part cannot keep the water from leaking.

That’s why water leaks from the base and spreads through the entire bathroom. It will eventually cause a bad odor throughout your RV.

Make sure you clean that round-shaped rubber regularly and check whether it’s okay.

  • Water Not Flowing Into The Bowl

After finishing your job, if you see no water flowing into the bowl, it instantly makes you angry. Well, it might happen with Dometic 320 series toilet.

A clogged water valve screen causes this problem. Somehow, the valve screen of this toilet gets clogged pretty fast.

As a result, water cannot come to the bowl when you flash. It can be irritating. On top of that, it’s pretty unhygienic as well.

So, make sure you clean the valve screen for water debris frequently.

  • Water Will Not Stop Flowing

We have already discussed the now water flowing issue. But sometimes, in Dometic 320 toilets, water does not stop flowing after a flash. It will cause multiple issues.

On the one hand, it will empty your water tank unnecessarily. And on the other hand, your black tank will top up.

This problem happens because of a faulty water valve. You will have to check the valve and change them frequently; otherwise, it will keep happening.

  • Parts Not Easily Available

Another problem with Dometic toilets is that their parts are not widely available. Since it’s an RV toilet, you won’t find it in regular shops.

You will have to order them from Dometic.

However, there are some off-brand parts available, but you might not find them near your home. Plus, there are lots of concerns about their quality.
