Common Dometic 310 Toilet Problems

Common Dometic 310 Toilet Problems: Troubleshooting

Let’s take a closer look at each of the problems, and most importantly how you go about fixing them yourself. (for the 300 model, see this separate guide).

1. Clogging

Clogs are the most common problem with any toilet, but they can be especially troublesome in RV toilets because of their small size. Toilets in RVs typically have a smaller trap than standard home toilets, which means they can clog more easily.

The best way to prevent clogs is to use less toilet paper. Never flush anything except RV-approved toilet paper and human waste. All other trash should be thrown in a garbage receptacle.

Another fantastic way to clear a clog is to make sure you use plenty of water every time you flush your RV toilet.

Also, set a calendar reminder to use toilet cleanout products like RV Digest-It once a month. This will help keep your sensors and pipes clean so they don’t become corroded or blocked.

If you do end up with a clog, there are a few things you can try to clear it. First, use a plunger to see if you can dislodge the clog that way. While this typically doesn’t work because of the way your RV plumbing is designed, sometimes it’s worth a try.

If that doesn’t work, you can try using a snake or an auger to clear the clog. This is usually the best way to clear a toilet clog in an RV.

2. Leaks

Leaks are another common problem with Dometic 310 toilets. The most common type of leak is a seal leak, which occurs when the seals around the toilet bowl or tank become damaged or worn out.

To prevent leaks, it’s important to check the seals regularly and replace them if necessary. It’s also a good idea to avoid using harsh chemicals in your RV toilet, as these can damage the seals over time.

If you do have a leak, the best thing to do is to replace the seal as soon as possible. This will usually fix the problem and prevent any further damage.

3. Slow Flushing

Slow flushing is another common issue with Dometic 310 toilets. The most likely cause of this problem is a build-up of sediment in the tank, which can slow down the flow of water and make it difficult to flush the toilet properly.

The best way to prevent this problem is to clean your RV toilet regularly. You should also avoid using harsh chemicals in the toilet, as they can contribute to sediment build-up. However, sometimes hard water can cause sediment build up and there’s not much you can do about that.

If you are having problems with a slow flush, the first thing you should do is clean out the tank. This will remove any sediment that may be causing the problem.

If that doesn’t fix the issue, you may need to replace the entire flush valve assembly.

4. Odors

Odors are another common issue with RV toilets. The most likely cause of this problem is a build-up of waste in the tank or pipes.

This can happen if you don’t clean your RV toilet regularly or if you don’t use a cleaning solution regularly. It can also happen if you leave your black tank open all the time.

The best way to prevent odors is to clean your RV toilet regularly and leave the tank closed except when you need to drain it.

If you do have an odor problem, the first thing you should do is clean out the tank. This will remove any waste that may be causing the problem.

5. Pedal Not Working

If the pedal on your Dometic 310 toilet is not working, the most likely cause is a broken or damaged cable. The cable connecting the pedal to the flush valve can sometimes become disconnected or damaged, preventing the pedal from working properly.

The best way to prevent this problem is to check the cable regularly and make sure it’s still connected. You should also avoid putting too much pressure on the pedal, as this can damage the cable over time.

If the pedal on your Dometic toilet is not working, the best thing to do is to replace the cable. This will usually fix the problem and restore proper function to the pedal.

How Do You Replace The Ball Seal On A Dometic 310 Toilet?

The ball seal is located at the bottom of the toilet bowl and is responsible for creating a watertight seal between the bowl and the tank. Over time, the ball seal can become worn out or damaged, causing leaks.

If you need to replace the ball seal on your Dometic 310 toilet, the best thing to do is to purchase a replacement seal from a Dometic dealer or retailer.

Once you have the replacement seal, simply remove the old one and install the new one in its place.

Here’s how:

  • Flush the toilet to empty the bowl and tank. This ensures that there is no water left in the bowl or tank that could potentially leak out when you remove the ball seal.
  • Remove the two bolts that secure the bowl to the floor. This allows you to remove the toilet to reveal the ball seal.
  • Lift the bowl off of the pedestal and set it aside. This gives you access to the ball seal underneath.
  • Unscrew the old ball seal from the bottom of the tank and discard it. You’ll make room for the new ball seal and be able to clean up the area before replacing it.
  • Screw the new ball seal into place. This is easy to do by hand, but you may need a wrench to get it started.
  • Reattach the bowl to the pedestal and secure it with the bolts. Be sure not to overtighten the bolts, as this could crack the porcelain.
  • Test the toilet to make sure there are no leaks. If your toilet is still leaking, you may need to replace the gasket between the bowl and tank. This is a relatively easy repair that can be completed in just a few minutes. With a new ball seal in place, your toilet will be as good as new and should no longer leak.

Why Does My Dometic 310 Toilet Smell?

There are a few different reasons why your Dometic 310 toilet might smell. When you leave your black tank open to drain, airflow backward through the pipes and up into the bathroom can carry odors that make it worse.

This is why it’s so important to keep your black tanks closed until you need to empty them.

It may also smell if you don’t clean your RV toilet or if you don’t use a cleaning solution regularly. Keeping your toilet as well as your black tank clean will go a long way in preventing odors.

If you do have an odor problem, the first thing you should do is clean out the tank. This will remove any waste that may be causing the problem.

If the odor persists, you can try using a deodorizer or cleaner specifically designed for RV toilets. These products are usually available at RV dealerships or retailers.

With a little effort, you can keep your Dometic 310 toilet smelling fresh and clean. Regular cleaning and using the proper products will go a long way in preventing odors from taking over your RV.
