Domestic 310 Repaired Pronto

This is just what I needed to refurb and repair my Dometic 310 RV toilet. Ordered one day. Received it the next. Tried all of the local RV dealers and they couldn’t help. Amazon came through. Price more than competitive and reasonable. This is the reason I purchase many of my RV items from Amazon. Other stuff too but when the toilet needs repaired, it has to happen!

Everything was included.

Didn't need it. The new toilet had one, hidden on the flange where it belonged. Oops

Question & Answer



Question :

I don't think i need the whole kit since i already have the hardware on the current 300 toilet. just the replacement seal. can i just purchase that?

Answer :

Dometic thanks you for your question. Yes, you can just purchase a seal. For further information, contact our support team at customersupportcenter@dometic.com.



Question :

Is this a genuine Dometic 385311653 flange, not a Chinese knock off?

Answer :

It appeared to be genuine. Looked identical to the OE flange gasket, & included bolts, nuts, & washers were very high quality. Fit our 320 series toilet perfectly. No leaks.



Question :

Did this kit come with instructions on how to install the seal ???

Answer :

No it does not, however installation is straightforward. Unbolt toilet from base. Remove old seal, clean floor flange and base of toilet, slide the new seal in place on the toilet, and then bolt back down. Be careful not to over tighten as Dometic/Sealand toilets can crack. If still unsure, there are several YouTube videos.



Question :

is this the same as the wax ring on household toilets?

Answer :

It works the same way a wax ring works on a home toilet



Question :

Package dimensions do not help please Part Dimensions: total diameter and inside diameter?

Answer :

sorry its already under the toilet bowl.



Question :

Does this kit work with the 321 model toilet?

Answer :

From the Dometic site: "Toilet bowl: vitreous ceramic (models 310, 311, 320, 321); polypropylene (models 300, 301)". The 321 seems to be a shorter version of all others. All of the listed models are of the "300" series. The differences: Poly vs ceramic bowls, rinse spray hose on some, height of the toilet, seat material, and maybe something I missed during my five minute review of the site. I installed a flange kit in minutes as it is very similar to domestic/US toilets. The flange bolts should be tightened to specs to prevent cracking the poly base of the toilets. Too little=leaks. Too much=broken base. And the recommended torque is inch pounds so using a 1/2" drive torque wrench is out. And the room which you have to place a wrench is minimal but my 1/4" drive torque wrench worked beautifully. Dometic has been more than helpful when I have called or texted for assistance. Lots of griping about their stuff but mostly it's a great company to work with. Now if they could only make a better RV refrigerator.



Question :

I just ordered the Dometic 320 toilet. Is this kit included with the toilet or do I need to order this kit in addition?

Answer :

My toilet came with everything needed. I bought this kit at the same time and ended up returning it.



Question :

Will it fit the 300 series white ?

Answer :

Dometic thanks you for your question. Yes. For further information, contact our support team at customersupportcenter@dometic.com.



Question :

The title says this is for a 300 series, however the descriptions says "Fits Dometic 110 and 210 Series toilets", does it fit a 300 series?

Answer :

Dometic thanks you for your question. Yes, this will fit the 300 series toilet as well. For further information, contact our support team at customersupportcenter@dometic.com.



Question :

Does a 300 domestic toilet interchange with a 310 dometic toilet

Answer :

Dometic thanks you for your question. The 310 will require 10'' of space from the center of the flange to the wall For further information, contact our support team at customersupportcenter@dometic.com.
