Dometic Flush Ball Seal

[Retired_Jim]

My Dometic Sealand 310 Toliet will no longer hold water. Anyone know where to find a replacement rubber seal? Will replacing only the seal work or will I need to order a new ball also? I seem to only find replacements for a 500 series toliet.

My 310 did the same thing and all it needed was a cleaning and alignment. I wiped off the seal with a little vegetable oil and also found the the plastic ball needed to be aligned by hand. It's not very strong and it not a whole ball. After a good cleaning I haven't had a problem since and that's been 8 months ago.

Jim,

Before going to the extent of replacing your seal, I would try cleaning the area between the seal & ball valve. You can use an old tooth brush for this or any stiff small brush. Per the manual here:

They are very knowledgeable and have all the parts in stock.

Here's a simple fix that might work: shut off the water supply, push the pedal and drain the water from the bowl, then spray industrial silicone spray on the flush ball as you work it up and down. You might be pleasantly surprised how easily this works (assuming you don't have a heavy buildup on the seal surface).

I tryed all of the above in my motor home.....as it was still under warranty it was replaced, the whole toilet. All the cleaning, oiling & what ever else they tried still did not work. The new one did fine!

Try one more thing. I have the same issue. When it won't hold water, press the flush pedal down and hold it down. Then reach in with a finger (in a glove if you want) and run it around the top of the seal pressing down as you do. It seems when TP gets caught or when you clean under the seal, it gets tilted upwards and the seal fails. Ever time it does, doing the push down routine I describe seem to put it back into place. Has worked for me every time.

I appreciate all the responses. With the trailer winterized and in storage, I will try all the cleaning and adjusting suggestions when the trailer comes out of frozen status.

I did what DocData757 said above a couple days ago and it solved the problem.

I had this problem. I put dawn dish soap and let set. good idea for storage. It works great.

Mine also did not hold water from new. Didn't get to dealer for warranty fix before it snowed. When I winterized I put a cup of virgin olive oil in the bowl, as I always do on our TT's when winterizing. This spring I took it in to dealer for the few warranty issues I had. They put water in bowl, flushed it, added more water, and let it sit while they did other tasks. Water never leaked out. In fact still had water when I got home. Olive oil fixed it!

Might be worth a try.

Your to good to your toilet, virgin olive oil, why not just plain old olive oil? Shoot just add some balsalmic vinegar and you have salad dressing!
Sorry, I couldn't help myself (humorus PTSD)
