Toilet won't hold water

We bought a 10 year old MH that hadn't been used much. It has a SeaLand china stool. We've tried vaseline on it with no success. Anybody have any ideas?

Does it have a metal band around the middle holding the upper and lower pieces together? If so it's pretty easy to replace the seals. Find the model # and purchase a seal kit. Sealand is part of Dometic. Any RV dealer should be able to help.

Try cleaning the groove where the valve slides into -- some people report success ab combo of manual cleaning of the groove followed by putting some olive oil or similar product to rehydrate the seal.

Toilet that won't hold water

I actually went out and checked the original window sticker and it had added as an option an Aria 12Volt toilet. I don't know if these function any differently from a regular toilet or not.

Is this the toilet you have or close to?
This thread may explain what your problem is.
If you can not clean the seal area its a expensive fix, your manual should give you this information on cleaning the slot.
This maybe what you need.

Yes, 007 this is exactly the toilet that we have. They mention using silicone grease. Perhaps that will do the trick. thank you!

I had the same problem the only thing that worked was silicone grease, on your finger and under the seal. Don't confuse plumbers silcone gease with silicone sealer. I went to Lowes and asked for it they tried to sell me silicone sealant the stuff in a tube that would have been some mistake. I got it at Ace Hardware its in a small jar with a screw on cap.

Plumbers grease as mentioned to clean and rehydrate the seal. When I store the coach for any length of time I put some water system antifreeze in the bowl to keep the seal in good condition.(The pink stuff)
This works on the china bowels,but will stain the plastic bowels.

We have a different brand, but I think the seals are about the same. We were told by a manufacturer's service rep that Vaseline should never be used on the seal. He claimed it damaged the seal and silicone grease was the only thing to use. I would not have any way of knowing if this is true but he was supposed to be the expert so we followed his advise. Fixed our problem with water retention and it has continued working.

True no Vaseline! It will work but it breaks down the o-ring over time. You are looking for a o-ring lube. Have used Dow Corning (Molykote 55) lube for years in commercial setting. Any lube designed for o-rings will work.
Note: a little goes a long ways, normally apply a little to fingers and draw o-ring between fingers. All you need is a light coating.
