RV Toilet Upgrade! Dometic 320 Toilet Install | Full Time RV Life

[@KyletotheRescue]

Great video. I thought installing one of these would be a lot more involved. Think I may bump this up the upgrade priority list now. Thanks for the reassurance!

[@ExploringOurCompass]

Absolutely! It’s super easy!!

[@BobCATClaims]

After two Thedford‘s breaking (leaking) in just over two years, we decided to take your advice and upgrade to the Dometic 320, and we’re glad we did. And with all the useful tips in this video it was a breeze to install! I really appreciate all your helpful and humorous videos and continue to learn and be able to do a lot of the RV maintenance and repairs myself because of them! Thanks, brother!!

[@ExploringOurCompass]

I’m glad you enjoyed the video Bob! Thanks for the kind words!!

[@davidmorrill2943]

We have a domestic 320 on our RV for 4 yrs+. Flushes as yours but you can hold the peddle down down to get more waterin.

[@ExploringOurCompass]

Ya we do that, I think I was just hoping for more pressure during the actual flush. Oh well, it’s been almost 3 years now and we’re still happy with it!

[@SNCnIdaho1959]

THANK YOU for the morning laugh. I've never seen anyone so excited about a toilet. We're buying a Winnebago motorhome, and they come with a plastic toilet..........unacceptable. So, I was curious how hard it would be to change that out for a porcelain toilet; your video was so helpful. Looks simple.

[@ExploringOurCompass]

it's pretty straight forward and easy!! Glad we could make you laugh!

[@td6377]

We have one, it sprays way more than that. it could be restricted by the additional fittings and on/off valve, each will add a % of restriction.

[@ExploringOurCompass]

Good point, maybe that’s what it is. Thanks for watching

[@skoffco]

Damn, I think you should’ve stayed with the original one. If it ain’t broke, don’t fix it.

[@sbramel93]

My 321 sprays the same amount in the front, it’s not much. Oh and these toilets are meant to be disposable because they don’t sell many parts for my 3 year old toilet so I have to toss it in the landfill. The 510 has more parts available.

[@jammer9597]

We bought our camper in 2017, it has a Dometic 310 in it, we use it about five weeks a year in our short Michigan summers. We love it, it has never failed, turn the water pressure up to 60-65, it will work perfect, you'll love it.

[@ExploringOurCompass]

Thanks for the information! Enjoy those Michigan summers (when they come back)!!

[@JamesL5150]

Went from the 300 to the 320, I do like the size better. My only complaint is when you get those parks with crappy water pressure, it doesn’t like to flush well but I guess that’s an issue with any toilets unless you install a res. toilet with a tank and risk it breaking when you move. That valve was a smart idea, I did the same. Edit:: After watching the whole video and seeing you had the same issue with water pressure…. I find that it doesn’t start working “right” until up around 60ish psi. I know everyone gets scare about higher psi but in our newer rvs with 1/2” PEX, it’s rated to 110, so if you have pressure available, turn it up some more. But be sure you didn’t kink a line also. My problem is these parks that reduce down to like 45 psi. Even older rvs can handle 55-60 unless they are just junk.

[@ExploringOurCompass]

Yep the water pressure is still something that has yet to make me happy with the 320. You are right though, 60 psi definitely makes it better. I also notice that it flushes a little better if I'm running off of my water pump instead of city water.

[@MONEYZ123]

I don't think the issue is that the lines can handle higher psi, which you are right about, but the components that they are attached to can not handle higher psi, such as cheap plastic faucets/shower heads/black tank flushes. Its the water components that you need to worry about.

[@daviddrake806]

You might find that there is a shark bite push-on valve that's "full port". I'd not worry about the life expectancy of the shark bite as you are at a lower pressure AND the fitting is readily accessible and visible--so if there is a problem you can fix it. I've NEVER had one accidentally come off but for SURE have had to fight with them to get them off once those metal teeth as set in.IDK about the 90. You can also go to 1/2" copper that also works fine with sharkbite and will definitely give you a MUCH bigger Internal Diameter and the resulting flow. Or maybe use a push-on size adapter to go up a size in tubing to 3/4"PEX (not copper that'd be nuts) and then those valves and 90 will have a bigger Inside Diameter/ID that should ease the restriction. I DO agree that it's the cheap valves and plastic parts of showers and sinks that are going to give out with the higher pressure. It may take some time for the cracks to propagate to failure but when it does....it'll tend to be full blast--NOT like a metal water heater that's rusting through and starts seeping a little for days/weeks before a real stream shooting out. It might be worth it to run a bigger line or even 2nd pump or add a 2nd pressure adjuster to bump the pressure BACK down to the rest of your rig. IDK how complicated your plumbing is but seems you have the tools you just need the fittings and couple of sticks of 3/4" pex. Oh there is a snap on brace that will curve the 1/2" 90degrees. You'll need 2-3" so may have to relocate the cut-off valve back to somewhere else before the bathroom floor but it should definitlely help and is a big reason why PEX pipe can usually get away with the flow penalty of a thicker plastic sidewall/smaller ID penalty. I'd try copper+Push-on Fittings (take out in the inserts that keep the plastic PEX from collapsing first and then maybe a second water pump just to the toilet..BTW someone commented that the seal on a 320 is now known to cause waste water to collect where it mounts and rot out the wood/mounting material....I haven't checked it out but the OP responded they'd heard that too and there are no more 320s for sell on Dometic's Amazon store--only older stock in retail or clearance warehouses... Just saying...--DD

[@leea.6101]

When you added those 1/2" crimp fittings for your shut off valve, you restricted the water flow. You should have used push to connect Sharkbite fittings. They lock over the water pipe and not in the pipe. The don't restrict water flow.

[@kathleenrutherford733]

This is perfectly what I needed!!! Thank You!! I am doing mine today, I got the 310 version. I love your channel already, bless you

[@thomaspope1525]

Thanks for the instal and review. I think I am going to try and build a pressure tank in the basement of the coach and run dedicated lines to the toilets. If possible use a domestic tankless toilet as water use I not an issue since I am hooked up to my RV lot 95% of the time.

[@ExploringOurCompass]

That would be pretty cool to see

[@LoveShackBBQ]

Our GD Imagine came with the 320 bowl. That’s the way it flushes on ours. Nice install.

[@ExploringOurCompass]

Your Imagine came with the 320?! That’s awesome! Do you like yours? So far so good for us!

[@LoveShackBBQ]

@@ExploringOurCompassI’m really happy with ours. Better than the last RV with the similar Thetford. There’s that one area you’re talking about, that never washes off, but were not full time and is easily cleaned. Also, the 320 is a porcelain base. Something a lot of campers dont have, however my 2150RB has a cheap plastic lid that moves around a lot. Replacing it soon. Also, the water supply line on mine isn’t as nice as what you did. It fell off and leaked on a few trips, I thought it was the shower at first. Love ya from the Shack!

[@ExploringOurCompass]

@@LoveShackBBQ yikes, the water line fell off!? That sucks! I’m happy with this one so far also, it definitely has a better feel to it and cleans the bowl a lot better.

[@LoveShackBBQ]

@@ExploringOurCompass it didn’t fall off but yeah man, it was a cheap hose clamp that wasn’t in place. There’s always something on an RV that needs repair, no different than anything else. It was a small leak for us, but enough to bring big concern. Which brings me to say, dont slack on a daily inspection of your full time RV. Little errors bring Big issues.

[@ExploringOurCompass]

It’s always something, right? We had a huge leak in our shower about 2 months after buying our Solitude. The PEX clamp just fell right off and so did the water line. Lol

[@mjr2470]

Mine came with this. The flusher stuck since i bought the camper new. I have to pull it up to stop water flow

[@ExploringOurCompass]

That sucks! We luckily haven’t had any problems with ours so far

[@reelmckay68]

I have a domestic 300 in my trailer.i bought a domestic 320 and it wouldn't line up on the flange to mount to the floor.so I had to return the domestic 320 toilet.instal my old toilet because the mounting flange could not rotate to line up with the new toilet holes.

[@ExploringOurCompass]

Was the flange screwed in to the floor or glued in? Sometimes the ones that are glued in can’t be rotated! Sorry you had that issue

[@reelmckay68]

It’s is screwed into the floor. But also glued in

[@ExploringOurCompass]

Ya that sucks. It would be a little bit of work to line it up correctly.

[@Kebekwoodcraft7375]

I use the hand sprayer so it spray where I need 😊 But I need a bigger toilet 🚽 seat 😊

[@ExploringOurCompass]

The bigger toilet seat is definitely nice!

[@catskinner7564]

I'm switching mine out I have the same one that you removed thetford junk trying buying parts for it waste ball valve shaft to the foot pedal is junk try finding it brakes real easy I came to the same conclusion as you did sing toilet awesome

[@ExploringOurCompass]

Yep! We’ve been very happy with the Dometic 320 so far. We did change out the lid from what came with it though, to a slow close lid. Much better!

[@Upforthejourney]

I've never been so excited for a toilet video. LoL I hate our stock throne, for the same reasons. Geat video.

[@ExploringOurCompass]

lol same here, although I wish this one had just a little more water pressure near the front of it! It's definitely more comfortable though!

[@harven7974]

When I was researching this toilet it says specifically gravity flow with basically means poor pressure. I bought this same toilet I haven't installed it yet

[@glennmassengill3532]

I definitely need to upgraded our camper pooper lol

[@ExploringOurCompass]

Definitely 😂

[@Hezelcarl1]

Your original looks like a Thetford. Although I could be mistaken.

[@ExploringOurCompass]

Yep, it was a Thetford!

[@MONEYZ123]

Been thinking about doing this switch just so I can add a bidet 🤣 Thetford's don't have standard toilets seats so a bidet wont work 😑

[@ExploringOurCompass]

haha that would be awesome! 😂

[@builtcountry9701]

My valve continues to break on my 310 and i have now ordered 4 different types. In my opinion the 300 series foot pedal is an absolute design mistake and you're better off getting one with a button or some other type of inlet. Mine has broken again this morning and is currently sitting with a toilet brush wedged into it so I don't have to shut off all the water to my entire system

[@ExploringOurCompass]

I'm not too familiar with the 310, is the foot pedal the same as the 320? Luckily we've been ok so far but haven't said that, I probably just jinxed myself.

[@alzathoth]

How much do you need to tighten the bolts? I need to remove my toilet to fix a leak and am afraid of cracking the toilet.

[@ExploringOurCompass]

30-40 inch pounds is the correct answer to this but on this install I just made them snug until I felt comfortable.

[@brinstinrogersjr1620]

I have a silly question. When replacing a toilet. Dose the toilet have to be the same brand as the old one?🤔

[@ExploringOurCompass]

Nope. Our original was a Thetford and the new one was a Dometic.

[@brinstinrogersjr1620]

Okay awesome thank you. Yeah my og is a thetford and just order a thetford aqua Magic" but my og is a thetford aqua Magic starlight.👍

[@ExploringOurCompass]

Ya I think you'll be fine! If you were to run in to ANY type of issue, it would probably be the water connection on the back not lining up quite the same but that still probably wouldn't be too bad of a deal.

[@Hezelcarl1]

I’ve installed the toilet in a house trailer. Meaning not an RV. Residential toilet The process is slightly different because you guys have to use a rubber seal as opposed to a wax one. flange seal.

[@ExploringOurCompass]

Ya, that’s really the only difference.

[@JamesL5150]

I’ll throw you another tid-bit on the 320, I learned from experience. If you ever, by chance or stupidity, run out of propane in the winter in freezing temps….after thawing everything out, you may find that the foot pedal is a bit resistant. DO NOT FORCE IT!!! Honestly, it didn’t take much extra pressure but it snapped off the smallest bit of the tip of the plunger for the water inlet valve so it wouldn’t flush. Apparently there was still a bit of ice in that valve. But, good news….you can get and replace just that valve fairly easily. I think there is a video of that here on YT somewhere. Someone else had somewhat the same issue I did. 😂

[@ExploringOurCompass]

wow, good to know 😂

[@thumperpaul]

So, aside from you installing the water shut off valve, would the existing water pipe and connector work with no issues on the new toilet?

[@ExploringOurCompass]

It was a little off with being considered correctly lined up from what I remember but it wasn’t enough to cause issues.

[@prodabpaul8736]

Thanks for the video boss! Now i have a question; is the toilet flange a special rv one? Or is it a standard residential flange? Keep up the good work

[@ExploringOurCompass]

hey thanks! The toilet flange on the RV is usually a special one. A different size than homes, I believe those can vary in size.

[@Gdone]

All dometic toilets only have couple inches of water in the bowl

[@Jc-bo1uu]

We have a Dometic too in are RV and the flush valve keeps leaking and I replaced it 2 times. I just had it replaced 3 weeks ago and we are camping for 2 weeks and it worked great for 1 week and it just started leaking again. How is yours doing? And do you have any ideas?

[@ExploringOurCompass]

Ours has been great for 2ish years now, no valve issues so far, knock on wood! I’m honestly not sure but the only thing I could think of would be to see what your water pressure is. Maybe it’s high and messing with the valve.

[@Eebsmom]

Installing mine today. Thanks for the how-to. And for remembering women are doing this, too. ❤

[@ExploringOurCompass]

Absolutely! Hope it was an easy install!

[@BWAusTX]

Will a household toilet seat fit on this?

[@ExploringOurCompass]

yep! We replaced ours with a slow close seat and lid

[@ClintMyhre]

Is your 320 still functioning without leaks, or does it have the same leak problem as other Dometic models where the bowl meets the pedestal?

[@ExploringOurCompass]

It’s been working great! No leaks so far, knock on wood!

[@ClintMyhre]

Other than the obvious comfort/size and seat differences was there any reason you did not like the Thetford? Did the Thetford break down or leak in some way? I'm actually contemplating replacing my Dometic 310 with a Thetford Aqua-Magic Style II (which is what you had) because of the leakage problems with the Dometic. The insides of the Thetford look like a much better design. The Dometic is designed to leak in my opinion. I do not have enough clearance to the wall for a Dometic 320. The Dometic 310 is smack against the wall and the 320 needs 11 inches (1 more inch than I have.)

[@ExploringOurCompass]

Nope, other than those 2 reasons and the small wash nozzle at the back of the bowl, the Thetford was fine. It was a great toilet for what it was made to do! We just wanted something a little different. I actually installed the Thetford from ours in to my Mother-In-Laws rig and its still running fine to this day!

[@pull-up-onmeh5138]

yeah, to be honest I think that is a design error!!! And I really don’t like the fact that it doesn’t fill the bowl up with water at all after you flush it so you get that P sprinkle that bounces out of the toilet onto the floor and the walls. Not a great design !

[@monztur]

My 320 lasted 2 years. Then the foot pedal shaft broke. So i thought no big deal just get the parts. Wrong they dint make these parts for this toilet tried making one 3D part lasted 4 months broke again. Now have to buy a new one what a piece of junk. Good luck.

[@ExploringOurCompass]

Wow, sorry to hear about your issues! Thanks for the heads up!

[@chrisscott8239]

Just got off the phone with Dometic trying to diagnose an issue as the bowl won’t hold water after replacing the seal. They acknowledged a manufacturing issue but won’t do anything about it. The two parts with the issue cannot be replaced and said the entire toilet would need to be replaced, at my expense. Basically, it’s a throw away POS! I’m shocked by their arrogance!
