Thank you for being thorough, direct and with visible detail without a lot of needles elaboration and long period of irritating music before getting around to the subject at hand. What a breath of fresh air! And thank you for the helpful info as I am having the same problem.
I thought it was a floor flange seal...im having the same problem. This video saved me alot of time. Thank You
We have been fulltiming in our Grand Design 397 for just over a year, and I noticed this problem three days ago. Thank you so much for this video!!
Did it ruin your floor yet? Our entire bathroom floor is soft. I can’t believe there isn’t a class action lawsuit yet.
Hey so I have s brand new rv. Just noticed this as well on my 2022 Noboundries. Don't know how much damage it has done yet. Any ideas on what I should do?Still under warranty so that should cover this right
Yep. Happened to me as well. 10 year old toilet. The gray foam donut seal between pedestal and bowl was not happy. The nylon grommet nuts are shot and the 4 long bolts were really rusted. Bought new larger 1/4” SS x 2 1/2” bolts but they would not grip the nylon inserts. Called Dometic company and spoke to a very nice lady, who contacted some sort of engineering or technical services group to see if they could supply me with 4 new nylon inserts. After a few conversations between her and the technical group with my insistence that they should be available, the answer was clearly NO we do not supply new nylon inserts. So basically, instead of replacing The round foamy gasket for a few dollars, and the nylon inserts, which shouldn’t cost more than a few dollars, I need to replace the whole stinking toilet. Unfortunately the 320 toilet is 1/2 inch too long to fit. This really stinks, literally.
Well..... Sounds like a tough one. YOu really have to check the installation manual and clearances. I know there are three different depths of toilets based on the discharge flange. There are other manufacturers to look at as well that might have what you want.
I found a solution
You nailed it. I just pulled mine about and rebuilt it. 310 model. Full of piss around edge cavities and was overflowing at middle seam.
Yea.... Just can't even imagine how many people's property has been damaged by Domtic toilets.
I have had problem with smell and water looked every where seen this vid had my toilet(300) out on ground in a minute you are the MAN THANK YOU
Same issue...1.5 yr old 320 model.
Thanks have new rv and found water on edge. Save floor just in time. Will do myself. No need to travel three hours for simple repair.
Yep - And dont have to wait for the repair department to messup other parts of your RV. It took me a couple of hours but I was really investigating what had happened. The job all in total would take me 30 mins or so. Just wear gloves and then change them after getting glue on them. Wash and dry the foam rubber seal.
Just get the 310 porcelain. I had the plastic 300 and got rid of it before I started having problems. I had the 310 in my Coleman before I traded for a bigger camper. And saw this in my new camper. Actually it's a 2021 wildwood and immediately changed it. You can interchange the valve system so I kept the plastic one for parts.
Thank you so much!!! You saved me many hours of aggravation and wasted time!!
Our floor is a disaster… I have a 2017 Keystone elite with a Dometic 300 and now that I have the floor ripped out I am furious this could’ve all been avoided by a simple recall years ago!
Is there a #Classaction lawsuit started yet??? Sign me up!!!
Thank you for this video!
I would like to know as well. Our floor is soft. It’s a huge issue now. We have to step where the beams are to not fall through. I replaced the floor around the toilet ates so that’s strong now. Seems that it’s rotting away more and more. We’re full timers in our keystone cougar half ton. Any info would help.
Sad - Sorry
Yea it is sad..... for sure.
Exactly what I was looking for!! Thank you.
And four years later.... still defective. The toilet in my 2021 Grand Design Reflection 278BH showed signs of leaking twice. The first time, about 6 months ago, I tightened up the two base nuts and it stopped leaking (or at least the water on the floor). Just noticed again today, tightened up the nuts a little bit more.. but after seeing this video. I had better take it apart and inspect.
Just remember.... its not the flange seal for the toilet to the floor. Its the seal that joins the two halves of the toilet together.
Thank you for the video. I am currently having this problem and having been losing my mind trying to figure out the issue. Will comment back with the fix.
same here, this is a HUGE PROBLEM,need a class action law suit.....
Yea - super unfortunate.
We have a Dometic 320 model and it was purchased in 2021. It's been smelling like that since we install it. I won't ever buy another Dometic nor will I recommend Dometic toilets for this reason. They should stand by their product and recall the toilets or make a design fix for the existing toilets out there.
Great video, all others had about sewer smell, like you only a water leak, this will get me to source of leak. Thanks
Thanks for the advice brother have the same issue, pulling my 300 this weekend.
Same thing just happened to my Dometic 320 it's a 2012 all this years worked perfect till a week ago that started leaking between the bowl and base, I'll do what you suggested and see how it works! Thanks for the video!
Glad I could be of assistance.
Thanks for your video. Same problem with my Dometic 320.
Good info, I just noticed water seeping out around the base of our toilet too when I am holding the flush pedal down to fill the toilet is when it's happening.
That sounds like a leaky water valve: Here is how to change it. th-cam.com/video/hVT75xgnkn0/w-d-xo.html
I'm going to have to replace floors at least in bathroom and past walls around it I'm scared to look underneath I just realized this was what's causing my floors to be...soft to begin with but now rotten idk where to even start💔💔💔 this is my full-time home
Having some seapage from our dometic now. Thanks for putting this out.
Really made me upset seeing the Dometic rep at the Tampa RV and getting a blank stare like I was stupid. Had to pull out my phone and show him that Dometic was aware they destroyed so many RV's
Yes - You can fix the 300 series. I fixed mine about a year and a half ago and it smells great.... (most of the time).
Use the sealant avaliable at Homedepot - Dap 18388 Ultra Clear Waterproof Sealant
It's a toy toilet. Like a plastic Barbie toilet. At least it's plastic. Most RV stuff is made of paper.
You are correct kind of junk. I will say since I fixed my unit and sealed the center section I have had no issues.
My camper was made in 2016. I'm having other issues with my toilet. Water valve and just yesterday, the flush pedal was out of alignment making me think it was the seal. Haven't had that problem yet, knock on wood, but will know if that ever does happen and how to fix it. Thanks!
replacing the valve inb a few days I will address this lso , thanks for the heads up
I am having the same problem with my Dometic 310. Called Dometic, they only recalled the 300. She wouldn't help at all. So my husband took it apart like you said in this video. Now we can't get the screws back in, he said there must be something on the other side that was holding in the screws before he took them out and must have fallen off. Any suggestions?????
4 nylon grommet nuts. They get brittle and are no longer effective.
I replaced the valves in both our toilets in our trailer and the main one is still leaking while the other is fine. Although, this hadn't started till we had the freeze a couple weeks ago
Those flush vales are very cheap.
I just called Dometic regarding my 310, representative said even due they are aware of the problem, they never admitted to it, she looked up the serial number, said the manufacturing date is more than 2 years old therefore she can not help unless i email proof rv was purchased less than 2 years ago and i am the original owner. she also told me that to her knowledge no design change has been implemented since 2010, and they still receive calls regarding this issue with new less than 2 years old units and send replacements. Maybe we should sue them?
The Zeroth I also have a 310 and I spoke with dometic about an internal leak and they told me that the issue I was having was the water valve. I sent them a video of me operating the valve manually with no leak coming from the valve but still leaking internally. They just said my problem was the valve and that it has been a common problem. I know the valve is good
@@jonathanquezada1403 Thats a lie because the valve is on the exterior.......
The fix is compensation of damages and inconvenience of an investment!!!
So far. It’s much better and is solid and doesn’t crackle.
Same issue in my 2021 Montana High Country! Thanks the video. Rv parts are expensive and poorly made!! Keep finding issues after issues. Pandora’s box
Unfortunately the RV industry is a bit lackluster. Of all the RV is that I have purchased in the past I have had pretty good luck for the most part. But I will say this. My initial walk-through of the RV is very picky and everything must be fixed before I leave the dealer. I never will accept a unit with issues. I do have to say that my experience has always been with travel trailers and fifth wheels. I have never taken possession of a motorhome or class c unit. Domatic as a company has gone downhill. I've had multiple issues with equipment installed in my RV. Just recently we lost the refrigerator about two months out of warranty. After investigating this further it appears that the refrigerator core was made from cheap steel and rotted out. I have always employed the technique of keeping the refrigerator going and never storing it. This keeps the core warm and usually increases the longevity. So we had to spend $1000 on a Furion electric refrigerator and trim kit. We had issues with our water heater as well that is a Dometic. If I were not a do it yourselfer...... I tell you.
great video. thank you for sharing
Thank you for this info. I am currently having that very same issue.
Thanks for the video, I just noticed that problem today and will try your fix to avoid floor damage if possible :-I
It would help if you also showed how you got to the side bolts that commonly hold a house toilet onto the the floor flange. I cannot figure out how to get to that point. I have a ceramic toilet with a plastic skirt I don't know how to remove. Thank you.
Should be like a standard toilet flange with toilet bolts. Really can't elaborate on it but to say it's the same as every toilet I have worked on. Yours could be different though.
Wow thanks this my current problem , Dometic told me because it's 9 years old just buy another..
Yea. Very unfortunate. But will tell you... since I treated the gasket with e6000 and reassembled it, its has not leaked or smelled at all.
Just an update. I ordered the toilet on the 13th got it on the 15th and wouldn't you know after putting it in ,it has a leak too !!! Ill redo on Monday . It is the part at the foot operated valve. A tiny ball is pushed on as the foot lever is used and mine leaks and runs out of the bottom of the lever. I very wary of this brand now. They have their shipping down though ! LOL..WISH ME LUCK .
Zofoblues Zofoblues i agree. Going on 3rd toilet but this time we ungraded to a 310 series with wooden lid to stop the plastic from crackling.
Yes I'm familiar with the issue. Those valve is really suck.
did you get it fixed?
thanks for the video, it gives me a place to check problems
Is there a video showing how to do the fix? please make one.
Ok..... I guess I can take my toilet apart now that I have fixed it over 3 years ago. LOL....
Same problem! Thanks for the info
thanks for this!
Thanks
Thanks for the video good information
Thanks for this information. Good Stuff.
Thank you for explaining where it is failing. Apparently, our Dometic just reached its seal breaking point, and we're not about to buy another crappy (pun intended) Dometic toilet to replace this one. By any chance, has anyone offered you better brand options?
Thetford is another I have heard of. I don't know much about them though.
I hope this is the last toilet we have to replace. I thought Dometic was a good brand now I’m questioning that
The really sad thig is they have ruined a lot of RV's.....
They are not
dometic=cheap junk
Thank you. Do you think a different brand would work or a porcelain toilet?
Possibly. Typically what you have to look for is clearance behind the toilet fas measured from the center of the toilet flange to the back wall. If I recall there are 4 different sizes of toilets. There are other RV toilet manufacturers out there. I don't think you could use a home toilet because it would fill up your black water tank very quickly.
Regarding your "fix" you've mentioned RTV silicone adhesive sealant, E6000 high viscosity adhesive and DAP 18388 flexible waterproof sealant. I only want to do this job once so which of these three do you recommend most??
I used E6000 but a silicone sealant is flexible enough. I used rubber gloves with the E6000 to really work it into the gasket. But be warned..... Only do this after cleaning the gasket really good and drying it. Have your surfaces clean and ready to reassemble. Discard the gloves after putting the seal in place.... It makes a real mess.
@@PilotCooking Thanks, I'll take your advise and get this done on Wednesday. Dometic is now making all claimants go through their local dealer/service center to this warranty claim. The locals are swamped, have no stock and no availability from distributors, making them work directly with Dometic which may take forever. My conversations with Dometic today indicated it would probably be weeks before I would ever see a replacement 300 toilet; their claims are back logged and new stock flies out to fill these claims. I can't wait so I'm fixing it under your guidance. Wish me luck and good skill.
@@PilotCooking Mission accomplished (ugh, I hate phrase). I would seem the E6000 added some thickness to the gasket complex even though I was quick as a bunny and had the toilet screwed back together in no time. How do I know that? The toilet now leaks bowl water ever so slowly. I've ordered a new seal and hopefully that will fix this "leak" in my one year old Dometic model 300.
@@garyswanson2357 The seal in the bowl needs to be cleaned to get hard water off of it. It can be lubed with plumbers lube as well to keep the seal nice and pliable.
@@PilotCooking I did both of those things when the toilet was apart. I think the new seal plus lube with work. As for the out house stench... gone, even with the imperfect seal! Thanks.
Its happening in my 2 year old rv as I type. We are on a trip now but im gonna have to pull that toilet as soon as we get back. Very crappy cheap 300 toilet. I may just chunk it and upgrade.
It is fixable as I described. I get that dometic will supposedly send you a new unit but really too bad they didnt just modify the design when they saw the issue happening.
Bought a new travel trailer April 17,2020 and the toilet has the leak like in your video. I called Dometic gave them model and serial numbers and they are shipping me a new one free tomorrow.
Good.... then it worked..... They don't like me much....
Mine is 6 months old and been leaking for a while now. They don't want to warranty it.. said take it back to the dealer.
I bought mine used and my toilet looks like a 300 series but I cannot find that stamped anywhere. I dont think it is leaking anywhere like yours but it will not hold water and I cannot find any info on how to take it apart to replace the ball gasket or what kind of gasket I need?
The holding of water is a different issue. Can usualy be fixed with cleaning the hard water off the lip. Use gloves of course.
@@PilotCooking I actually found the gasket installed upside down. easy fix
@@motodrummer are you talking about the center section gadget or the bowl flush seal?
We are on our second 300 series dometic toilet. This time we paid $50.00 and upgraded to the 310 series. They say they have fixed the problem but they haven’t. It still crackles and pops so we went to a wooden seat that closes slowly for 25.00!
Yes, it is sad because Dometic used to be a good name! I just stuffed a towel, that I’ll have to throw away, in the back of our toilet to keep the smell down till the replacement comes next week.
What happen if the pedal don’t shut the water? Do I have to replace the entire toilet?
That valve is replaceable.
i just replaced a dometic 310 cause the pedal broke. I called them and they told me it's a sealed system and that i wasn't able to put a new pedal on. That's a lie. I watched a TH-cam video and you can do it and it's not a sealed system. They would rather you buy a 300 new toilet then to sell you a 20 dollar part. SCAM company.
Yea... It seems to be the standard way of doing business these days. Dont tell the truth at any cost.
Just noticed ours leaking. However, how we noticed it is the top portion of the toilet actually moves from the base portion, like it’s not connected. Anyone have that issue?
There are screws up inside that are accessed from the underside. Sounds like they are coming loose?
Thank you, i am having the very same problem.
How did you get the base screwed back onto the bowl? The wing nuts just dropped in the bowl and I can't get them out.
Once the toilet is off the two floor screws, turn it upsidedown and you will see the four Phillips screws that connect the bottom and top parts. Not sure what to tell you about the wingnuts... sorry.
Wish I’d seen this first. I called Dometic and they said the only solution is replace the toilet. Curious how CJ handled this
@@fwbenson57 I bought another toilet. I did not buy another dometic.
Same thing just happened to me, they fell inside the bowl CJ Gibbons did you get the wing nuts out I sure can't!
@@valeriemarik9042 nope had to buy a new toilet. I did not buy another domestic.
Do you know if this have been addressed in the new 320s?
I'm not sure.
What cleaners did you use for the caskets? I was thinking of dawn dish soap.
While wearing rubber gloves, I used dish soap, and cleaned three or 4 times. Then dried in-between papertowels. Then used a blow drier to get it completly dry. Used windex on the other surfaces to get them very clean before using the E6000. Using a pair of disposable rubber gloves I put the sealant on the upper and lower surfaces of the toilet and then massaged the sealant into the gasket before laying it down on the upper surface of the toilet while the toilet was upside down. When you put the screws back in make sure that you don't over tighten them. You are screwing into plastic. I let the toilet dry for 24 hours before using it just to make sure the seal it was completely sealed. We did that back in 2017 and have not had any problems since.
I just had one put in and the leaking is evident
Go figure.
It’s never been fixed! The second toilet was worse than the first!
Yes I’m glad it can be fixed but ours was only two months old. Brand new camper. So we used our warranty. Twice. We shouldn’t have to fix a brand new camper. Our neighbors bought a $75,000.00 camper and the roof leaked and ruined all their cabinets. Definitely a warranty issue! But, it is a hassle to take a camper in you have set up to live in. They came out the first time but my husband changed it the second time. We have three drains counting our washer. Hassle disconnecting to take it in.
Is this on the Dometic 320 as well?
Just searched the comments below and it appears that people are having the same issue with the 320 series.
@@PilotCooking Do you think I should just go with the Thetford aqua magic plus or is this repair pretty easy to do?
Seems like no RV toilets are reliable.
@@John-sn4hl I have had no issues since I did the fix with the RTV silacone. Had a leak on the water valve but nothing to do with this issue.
Can any clear silicone work?
I would say tub and bath silicone should work good.
UPDATED VIDEO - th-cam.com/video/VB2lJqpyDc8/w-d-xo.html
I just installed a brand new dometic 300
Series and it won’t hold water either, what a waste of money
Yea - Sad deal.
Is this issue on the 310 series toilets, as well?
Im pretty sure its on them as well. If they are the two piece toilet with the void just begind the lid attachment.
Im not too happy with any of the toilets. why don't they use real toilets. makes no sense at all. Really. I should have not bought an TRAV TRAILER. The cost is more than the VALUE of a real value of a home honestly after interest.
A dometic product with issues? Come on.
My shutter does not return anybody know about this?
I realize this is a year ago. The shutter assembly can be replaced you just have to dismantle the toilet. It's not very hard and it is a good opportunity to make sure that everything is sealed and not leaking into the Subfloor.
What's the sealant you used?
E6000. But RTV silicone will work too.
@@PilotCooking hello major! Are you still active on this chat? I have a one-year-old Dometic 310 that is leaking from the valve area. They sent me a new valve right away… Not acknowledging what I learned from your video just now… No surprise. Are people saying that their replacement valves are also faulty? Wondering if I should just do your fix on the old valve, or replace it and do your fix as well… Thanks for any comment.
@@LovingIntelligenceIsAll yes still following. I get the updates whenever a message is received. Hard to believe there have been 50,000 views on this and that domestic is causing such an issue with peoples RV's - should probably ask for a little bit of clarification before answering your question. Are we talking about the filler valve on the right side of the toilet that lets the water flow into the toilet? Here is a video for the water valve: th-cam.com/video/hVT75xgnkn0/w-d-xo.html.
