This is great feedback, thank you. I will definitely try the sanding and marine caulk in the future.

wouldnt the caulk interfere with the big black rubber seal most people end up replacing? otherwise could you get it out later on if needing to replace it?

About the 5200 marine sealant-- stipulate the FC ( fast curing ) type. Otherwise it will take a week before it cures

Thank you. Hopefully it helps.

You are welcome. Glad we were able to help. Thank you for watching.

I am glad we were able to help you figure out the problem. Thanks for watching.

We are very happy it helped you. Thank you for watching.

Thank you for the feedback and watching the video.

That is great. I am glad the video helped.

The 3-ish year mark is exactly when this happened to me (just this past weekend, actually). Has this fix worked long term for you?

You are welcome. Thank you for watching and I am glad the video helped.

Thank you. Good luck with the new toilet.

Thank you very much. We are very happy to hear our video helped you find the cause of your problem.

I did the exact same. I have a 2014 Bullet 310 BHS and it has had the problem since day one. When I pulled the bowl apart I was both sad and very happy. Sad that I had to pull it apart to begin with and that Dometic and Keystone did not suggest this and happy because when I pulled it apart, I found the dried mess thus letting me know I am on the right track. I would post a picture but who would like to see that. Thanks again for putting this together. Hopefully this will be smell-less season for the first time since I bought the camper. Thanks Again!!

Did you notice your smell in and around your toilet? I'm dealing with a bad sewage smell but it doesn't seem to be coming from the toilet, rather it's stronger by the exterior wall. I will perform this fix regardless as it seems a good idea for preventative reasons, just curious about what others have experienced. Thanks in advance!

Thank you.Yeah, I know but I rather do it now, than when its a mess lol. If this doesn't work, we will look at other options other than replacing for the same one.

@@firesideweekenders p.s install a siphon 360 plumbing vent. 1 it will help with the odors as it creates a negative pressure , and 2 it helps disintegrate all the matter so it ends up costing less in blank tank products. Will still have to use em, but you will use less.... have a good one!

@@kylezenklusen2041 I saw this recently and wanted to do it until I found out I have to remove the eternabond tape I just put down. I literally saw the video that same day. Soooo I’m going to wait a little on this.

Thank you. That is great to know. Thank you for the feedback and glad to hear you are getting a replacement.

Word of caution to users of a "replacement" 300 - we had the same experience with a newly purchased 2019 toilet - worked great the first year, then experienced the internal leaking and odor. After getting a warranty replacement in 2020, it worked for one trip, then same failure. I took it apart and it is the "new" two-seal model - which failed just the same. I'm now replacing with the 310 model.

You are welcome. Thanks for watching.

Glad it helped.

Glad we could help

Thank you. Don’t get too dirty.

Any update?

Thanks for watching the video. I have heard similar experience from others in regards to the replacements. Hopefully this holds you over a lot longer than one trip lol.

Thank you

@@firesideweekenders I came across your video while searching how to replace the valve in my Dometic 300. After watching you, I figured I might as well disassemble the whole thing and follow your advice. Please keep the good tips coming.

@@frankperry1543 thank you for the feedback. We are glad you found the video helpful. Happy camping!

Glad the video helped. Hopefully it wasn’t too messy lol.

Oh that is nice. They def could have plumbed everything different to allow for this upgrade in the 2022 ones. I think also some may have had the holes cut at different measurements.

You are so welcome! I am glad it fixed your issue

Oh nooo. At least you found the smell. Hopefully you fill resolve the problem soon. Safe travels.

Very good question for Dometic. Not buying another Dometic

That is great to hear. Glad we were able to help.

Oh no. Hopefully this can fix it for you. I just bought it at Home Depot. Any local hardware store should have it.

I am glad dometic is sending you a new one. I hope it works and you do not need to do this. Thank you for the follow up.

We decided we're going to replace it, and take the preventative measures before we install it. Thanks again!

Yea you will be able to remove it. It’s not glue. It may be just a little extra pressure to pull it apart but nothing crazy. Then all you have to do is remove/clean up the old caulk before applying the new seal.

@@firesideweekenders Thanks very much!

Sorry, I don’t have the full name anymore but in the future I would probably use 5200 marine caulk like another viewer suggested. It is more permanent.

Hahaha. This one wasn’t bad. Luckily it was never used when I did it.

Good luck. It def could be a number of things but this is a good start

We were having the same problem with ours. Dometic just sent us the replacement for the recall, but we all already know it’s probably gonna be crap too so I’m sealing it before I install it. Just to be safe. I also checked our vent stack but it looks clear. I remembered this video from when we initially had the problem and told myself once they sent the replacement I would seal it before installing it. One thing that I did when I wasn’t sure if the smell was coming from the back of the toilet was, I put a black tank sanitizing tablet inside the back of toilet. If that helps with the smell or you can smell the thing dissolving it probably means there’s liquid in your toilet. We have a 2020 keystone bullet so relatively new and I was also feeling some type of way like did we just spend $30,000 on a bunch of issues lol? I’ve heard that the replacement is it any better so I’m hoping sealing it does the trick if not, I’m just gonna go ahead and buy the 310.

Yeah, we couldn’t fit the 310. It would have been real nice. Not sure why they continue to have issues but it definitely needs to be addressed.

You’re welcome. Hope it helped

@@firesideweekenders There was alot of nasty water in there. Piss poor design. Thanks alot!

I don’t see why not. Just make sure to read the label to confirm.

Are you sure you have the dometic 300? Haven’t seen that before. May need to call dometic. It could just be how they are made now.

No issues yet.

It’s not caused by the outside unfortunately some of these toilets collect pee and feces water in a cavity behind or underneath the bowl.

I know I am sorry. Camping season is making it hard lol. I am working on one now. Hopefully it will be done soon.

I’m sure if you call domestic they can give you a part number and either buy from them, Amazon or camping world.

I haven’t had the issue but at the same time this is caulk. So I would assume at some point, it will need to be done again.

Not always true. Just pulled mine a part and it’s leaking at the center too. The base was not leaking at all.

I would do it now before you install it but that’s my opinion. They say they fixed it but some people still have the issue. It’s a hit and miss honestly

I've had raw sewage smell in my rv for over a year. Come to find out it's because dometic knew there was an issue with this toilet but refuse to issue a recall. They told me it's not a safety issue lol. Offered to send me the modified same toilet that has already been replaced once. Would not upgrade me to another if I even paid the difference. Completely ridiculous this toilet is being sold and was put into so many campers. they will not take responsibility for a major heath issue they are responsible for. Unfortunately they make about everything in these campers so you can't stay away from them. I will spend my money on anything other than dometic products. In the future.

@@dbill12478 I’m not sure as to the reason you are having problems, but my sewer is straight through and doesn’t collect in a black tank! The shower does collect in a gray tank and mixes with the sewer line with a no back up valve. This is why I believe mine seems to be working fine!

@@firesideweekenders same problem with a 2 month old 320. over hour on the support line and they are sending a new one, but assume will have the same problems. Will do the silicone before installation.

@@shannonshirk1079 let me know if the issue does come back. I hope it doesn’t. Glad they replaced it thought.

The bathroom had never been used. It was a brand new trailer. I felt it was safe enough.
