Secrets to A RV Toilet Installation Dometic 320 

This is the second one for the basement bat. ru-vid.comUgkxOuLt8IL_GxhhaK8DBuKEL-zV0UJVpWZn , works great

Wow... I've done similar toilet swaps FIVE times now in 11 years and always had the same issue you mentioned about water input being in different places. Always had to make some kind of a funky new turn in the line for the new toilet. That simple 20" hose adapter you mentioned (and linked in the video description) is absolute GOLDEN help! I would have paid you for that kind of advice! You are incredibly helpful and kind to your audience, and I will be sure to give you and your channel the credit it deserves when I do my next toilet swap next month! Thanks again!

Fantastic explanation of installation. Very thorough. My 5th wheel has a non-elongated bowl and I hate it. I guess I should be glad that I hate it since my anatomy needs the extra room. Thank you.

James thanks for the hint regarding the supply line replacement. Works great.

Thanks for the videos you do put out. I know it has to be a pain to do some of these videos. Plus all the editing to put on here. I don’t know how you have any time for anything else. I watch everyone you put out. My wife thinks I’m crazy. I tell her, you never know when you might need something he has showed me in the past. Keep up the good work. Lee

Your advice gave me the confidence to update our 18 year old short, yellowed toilet to the 320, and I installed the residential grade connection! Thank you so much.

Great "pro-tip" on adding the flex hose and valve. As always excellent videos in your "spare time". Thanks!

Adding valve makes lots of sense. Helps for future like you say.

Thank you so much for educating the masses.....very informative. That's what is very interesting to me.

I am happy with what ever you get a chance to record and share. I understand your job is the first thing you need to take care of and this is not your main job but takes a lot of time away from things like family and sleeping. I have replaced many toilets and still watched your video. Stay safe and healthy.

Awesome video, I just made this upgrade to my Highland Ridge Open Range travel trailer...I absolutely hated the Thetford toilet and was looking for an alternative. I used your Pro Tip and picked up one of those shutoff valves at Lowes. Very, very easy stuff...Thanks, great information. Yeah, I understand totally that filming does take a lot of time, but, it's fun to watch and videos like this are super helpful. I'm in Alabama and finding an RV technician is near impossible, but, I'm an engineer, so, like I said, this was easy.

Billy Bob Thornton is now doing Tough Jobs episodes?? 😂 I'm ordering this toilet today.

Working and trying to please the public is challenging for sure, I gave it up years ago some people are not worth it but my happiness is.

Hello, the Amazon link is for a different toilet; it is all plastic, but Amazon has it listed under Model 320. Thanks for the infomation. Always the best!

The valve is the only way I have been able to make the transition from PEX to the flex hose. Great tip!

Excellently done video on the installation! thanks for posting. One recommendation: consider to always use PEX crimp ring connections. I've heard of shark-bite push-on connectors failing. The crimp rings are rock-solid and really easy to use with a crimper.

The pressure of being a RU-vid star ! 👍

That one also will take a bidet. Saves a whole lot of TP in the black tank.

After decades in boats, we are switching to an RV. One thing I was interested in was the seat height. Keep the video's coming.

Watched this great video and then did my change over as an expert. Ours was exactly like the video, same old Thetford and a new Dometic 320. Used the Shark Bite flex connection as recommended and all went smooth. Whole job 1/2 hour. Thanks.

Thank you, thank you, thank you! Your Big box toilet hose suggestion enabled me to take my Dometic 300 series toilet install across the finish line. Before watching this video, I was struggling with the PEX plumbing configuration. Your pro tip saved me a lot of frustration and headache.

BEST Install video I've seen yet! I have a 2021 Gulfstream Kingsport UltraLite 268BH that developed a toilet leak this past November! The itty-bitty plastic round toilet just ain't getting it for me anyway! I'm 6'3 400+ and disabled, so the residential Elongated will be installed post haste! Thanks for the info!

Great video! You look really good without your glasses on, John. Thanks for showing how easy plumbing can be when everything is brand new.

I like the idea of a shut off valve cause I like to use the hot water from the shower and don't like the water coming into the bowl while I am trying to fill the black tank with hot water

Nothing like the Best seat in the House !

I always thought that I would enjoy an RV, possibly spending a couple of years touring the USA after retirement. After watching many of your videos I think my mind has changed. You are a master, unfortunately it seems there are not many in the industry.

As always - pearls of wisdom, Thanks! Would have LOVED to see the MorRyde Wet Bolt / Crossmember install, I am doing that to my Trailer in the Spring.

Thank you again for another amazing video *and* sharing the link to Amazon to take the stress out of making sure I get the right thing. I've ordered a Dometic 510 for the 2006 Winnebago Adventurer 38t that I just bought and just added this part via your link. You always explain things so well and make so many things less stressful than they would be without all the hard work and heart you put into your videos.

Excellent Video! You are " The Toilet King" I would of had you add a sprayer to the water line for cleaning the bowl. You can congratulate the new owner with his new best seat in the house! Well done!

Another awesome video. I’ll look for those hoses with the shut-off valve next time I do a plumbing repair. Love the outtakes at the end!

Excellent video. Thank you for taking the time to explain basic steps so I can do my install with confidence!

James another awesome video, really enjoy your approach. I also just met a former co-worker of yours Justin who moved to my area, he is great and said great things about you as well. Keep up the informative videos.

Great tip on the cut-off valve line. Thanks !

I agree with you about the shutoff valve - any time that I have to repair a water line, I'll put a shutoff valve in if it doesn't already have one. Thanks for the videos, and for anyone that complains about not getting enough of them, have them buy you a couple of police-style body cams, and just start uploading raw footage, then demanding that they edit the videos into something interesting in less than a week's time, and for free!

Ol buddy had some long dawgs dipping in the water and needed a taller terlet!

Thx for the shut-off valve tip. I installed one of those years ago at the condo, but haven’t done it in the RV yet. Cheers 🍻

My brand new Dometic 🚽 that came with the toy hauler already has a valve issue so I’m upgrading to the 320. This was an awesome video and that in-line valve tip is great. Thanks! 🔧 🇺🇸

That really did look simple. That was cool!

Another very informative subject matter I appreciate you posting this video especially since I’m thinking of changing my toilet out with the 320

Good video. Thank you James. Happy trails!

We have to replace our 310 gasket, thank you!

What you do put up is great James Thank You

Awesome!! Thank you so much I used your professional opinion and bought the shut off valve Genius idea

Great info! Especially adding the shut-off!! Sitting down on the Job!! lol! Good man reading the directions AFTER the install! lol! Thx!

Time for a go fund me for recording equipment, happy to help!

You are such a good teacher. Good job.

We have one of these Domedic 320s and I would love to see a full take down video showing how to replace the bowl gasket as well as all the other parts on this particular model. Thank you.

Longer is better❤

Great info! Especially on the modified plumbing...But riding the dog is too weird!

Great tip on the pre-built SharkBite/valve/stainless hose set up. I'm about to change my toilet to that same 320 and wouldn't have thought of that. On my way to the big box store to get that hose kit. Thanks man! (Fellow Phoenician) ;-)

Great tip on the hose! Im doing this same upgrade and you made my job easy

Thank you for the detailed video. It is much appreciated. By the way, I love the Bloopers.

Your the man. I am so grateful and have learned so much from your videos. Keep them coming!

Thanks, I couldn't find that connector anywhere around me tried 4 hardware stores. Link worked great.

I allways enjoy the videos everything is explained so well

Like the shut off valve , going to do mine! Thanks good work

The beard is looking good there Grizzly Adams.

I like the 320 not only for the elongated seat. I like that it rinses the entire bowl where the old thetford only rinses the bottom 2/3’s of the bowl. Bad design.

Thank you for sharing your knowledge. It's a big help

...still learning👍Thanks James👏👏

I enjoy whatever you do, whenever you can do it. Thanks. Filming has to at least double the time it takes to do anything.

I have one of those thunder mugs, they're nice. I like the flex hose and valve idea. My vacuum breaker valve went bad and slowly filled the bowl. I didn't realize it and tea bagged myself early one morning.😬 I've had just about everything go wrong with mine. I keep every spare part on hand.

Oh this is great I needed some plumbing shut off for my kitchen I hope this same fixture works there too. Love the shark bite part because I’m not a plumber lol

Very interesting James. We all have one of these in our rv’s and it’s great to see one swapped out. Rocking a beard these days James. Looking distinguished. Outtakes gave me a laugh. Hard not to get tongue tied on occasion.

As always nicely done

James, I’ve been trying to upgrade all the crappy plastic plumbing fittings in my 10 year old rig. I really like the braided line with a cutoff. Add that to my todo list!

Thanks for the tips

Great review- definitely going to help in the near future 🍻

Good job always better to have some thing better than the manufacturer didn,t put on and that,s the shut off valve you installed!

Man I didn't know they had those I'm going to get me one for my fifth wheel thank you... Thank goodness that's not a ☢️☣️ situation..

I appreciate the video. Very helpful!

Great to install with new black tank! Could have been a real crappy job😁. Really like the shutoff on the supply line as one unit.

Cool video. Get a tri pod for your camera so you have both hands to work with. Been thinking about putting shut offs on all my lines, never thought about buying a complete braded line with shut off valve already on it. See, your videos are not only cool and you are cool too, but very informative. Knowing you are a mechanic first and do videos as whatever, they do really help an individual doing these diy jobs. It is better watching your videos than asking on facebook and getting twenty stupid and sometime dangerous ansewers. Although you-tube does have knowlegeable people. Keep up the good work and film whatever you can.

Changing out that valve that way it's a damn good idea thanks I will use that . Got a question about your gloves, what brand Everything I have used so far shreds in minutes. I was an RV tech decades ago and for some strange reason you make me want to do it again. But then my old bones tell me I'm better off retired. Thanks for your entertainment.

Wow I like the shark bite with valve. Makes a lot of sense. Definitely a worth while upgrade. You need to hire staff to film, make up and lighting for you. Oh and a production editor 😂

Another. Fine. Job. At. Least. It. Was. New. And. Not. Been. Used yet

Another great video! The outtakes at the end are great. The videos are always good, but you have to make a living, too, so don't let your fans nag you too much. :-)

Very nice. I have no idea why the manufacturers don't just put the flex hoses in anyhow makes Alot more sense to me.

Wow, that was pretty easy I was thinking about replacing ours we have a 2019 Jayco Eagle I really don't like the one they put in so this is going to be my next project, I was looking on replacing the seal but now after seeing how easy it is to replace the whole toilet I just might do that.

Thanks, this is my next project, replacing a Thetford Aqua with a Dometic 320 in an AF.... My recall is that the 320 requires 10-3/4 inches behind it

good man, install the toilet and then read the instructions. that's the real man way to do it !!!! lol

Great one

Good video

I tell my wife the elongated ones have more room for the "Boys". Lol

Dang James, do you ever get to go home and sleep? You seem to be going non stop 24/7 It's not easy to find a good RV repair tech, and you seem to be in that top 5% Thanks for the video.

Thank you!!!!

thank you,

Just seeing this Video. Great job. One question… I have a 2008 Winnebago and the water line is that funky braided line not PEX. What size or what connectors would I need to put in the 1/4 turn water valve?

Very good video. Question, I would like to change the angle of my Dometic 320 toilet in my 2021 Keystone Montana 3781RL. I noticed at 7:08 in the video, you mentioned that you could remove the toilet flange bolts and twist the flange. Would this work without drilling new holes in the floor?

Never saw a hose with shutoff valve on it. I'll look next time when I go in a big box store

100% add cutoffs everywhere when working on plumbing that doesn't have a cutoff.

For our 2020 Forest River Flagstaff, we upgraded the toilet to the Dometic 320 however we have a fresh water hose pex clamped to the 1/2” elbow and then threaded to the toilet. Do you have a suggestion for fitting the fresh water hose something other than a shark bite? I don’t think the shark bite will be compatible with this type of hose.

Side note, install the bushing into the pex before you add the fitting to make sure everything seats correctly. Other than that, nice work. Edited to say, 1 extra inch might make all the difference

Besides the top screws on the flange is the flange glued to the downward piping? I ask because my toilet is installed wrong and I need to give our toilet a twist. If I can turn the flange a bit this would allow me to mount the toilet at the proper angle.

Hi just a heads up from a plumber, the braided supply is cross threaded on the toilet. Caught my eye as you where finishing up. Like your videos , learn a lot n I like your work ethic, this isn’t a criticism, just a heads up

I would have replaced that foam seal with a wax seal....Good idea on the s.s. flex line with the shut off valve.....

I want this toilet for our rv. Unfortunately the bolt is 1/2" off from the back. I don't know if offset flanges are good for an rv toilet. What do you say?

I like your video. But I have a question on plumbing is the industry going to push on connection/shark bite? I have a couple of leaks with crimp fittings. Thank you for any info you can give.

All of that for an inch! Wow.

I really like the use of the braided hose with shutoff. Any chance you have a part number? I always have to redo the plumbing which is great on labor but a pita to do sometimes. Especially switching from Thetford to dometic.
