Fun with buying an RV toilet

[belfert]

So, the valve in my Thetford Aria Classic toilet is not holding water again.  I replaced the slide valve assembly a year or two ago as you can't replace just the seals.  It is at least a half day to replace plus about $70 for the part.  I can't keep replacing this every year or two.

So, I decided to get a toilet with a ball valve.  I checked the Dometic catalog and website which both say the 510 series of toilets have elongated seats.  So, I bought a 510H toilet and it was delivered yesterday.  The darn thing does NOT have an elongated seat.  I called Dometic and they said none of the 510 series toilets have an elongated seat no matter what the catalog and website say.  I can return the toilet as I absolutely want an elongated seat.

I was told the Dometic 320 toilet does have an elongated seat.  This toilet cannot really be repaired so the toilet must be replaced if the valve needs replacement.  Anyone have experience with the Dometic 320 toilet?

 Gyess you will have to explain your version of "elongated",, I have the 510H and it IS elongated as it is NOT round...
The water control valve is also very easy to replace,, I just wish it were a little higher,, I guess I could build a pedistal for it.>>>Dan

The 510H is not the same size as a residential elongated toilet seat.  I happen to have an extra elongated toilet seat and it is nearly 3" longer than the 510H seat.

The 320 toilet is the one that can't be repaired, not the 510H.

The flush valve and the bowl valve seal are easily and quickly replaced on all the 300 and 500 series toilets. The plastic bowl valve (the dump valve) is not available, not even from Dometic. I know, stupid right? All 310 and 510 are round bowl, 320 and 520 are elongated.

Supposedly the entire dump valve can be replaced on the 510 series toilets.

Is there actually a Dometic 520 toilet?  I can't find one listed in the Dometic catalog or anywhere online.  The person at Dometic/Sealand told me that no 500 series toilets are elongated and I would have to go with a 320 to get elongated.

At this point I am considering just replacing the slide valve on my Thetford Aria instead of a new toilet.  I love the Aria other than the dump valve issues.  I think the dump valves are failing because some of the guys don't fully open the valve to avoid the odor and are closing the valve before the TP is fully through the valve.

We have the 320 toilet in the Bus, we have had it in there for 3 years without issue.

I have to say that it has not had a lot of use.

When we decided on the 320, it was to get the elongated Bowl/seat.

The wife insisted that it be a porcelain Bowl, looks and performs very much like a home flush toilet.

Another plus was the design includes a lip around the inside edge that would help prevent any water left in the bowl from sloshing out while driving.

When I was researching toilets, the only bad thing I heard about the 320 was the flush pedal can break off.

Then again I've known people that could destroy a cannonball.>>>Dan

About 2 times a year I just wipe the seal with vasaline and have never had any trouble

Use mineral oil it does not deteriorate rubber Vaseline will.

[muldoonman]

Silicone grease will work to lube the rubber seals also. What Microphor recommends.

Do those "guys" run a little water in the bowl after flushing? Teaching them to do that could make the seals last longer.

The toilet automatically adds a small amount of water to the bowl after each flush so that is taken care of.
