Having the roof fans on while flushing is a sure fire way to draw air from the tank and whatever comes with it.
I use tank probiotics to help eat the bad stuff away and help keep the tank clean. I add a couple of gallons of water and the recommended amount of probiotic to the tank after a trip and let it sit till the next trip. I use
THIS in liquid form, however I will probably buy
THIS pod version of the same product next time around.
I owned a Winnebago View motor home, and in many ways, WBO puts a lot of extra thought into their engineering. The go to great lengths to plumb the bathroom sink drain into the BLACK tank to add extra water to it, while everyone else does like my trailer and leaves the toilet only to the black tank. End result is that I rarely use the bathroom sink and I keep a dishpan in the kitchen sink to collect hand wash water and such and I dump it in the toilet to add to the black tank.
I have a Dometic toilet the previous owners installed. I do not like the height of it, I am not tall and cannot sit properly on a 17 inch high toilet (measured at the rim)(and also know as ADA height, meaning the government is involved in that calculation). That being said, the Dometic is a nice toilet and is indeed easy to replace the seal. I noticed it was not holding water, so I found replacement seals on Amazon. Off brand but it was a two-fer deal and they fit well. their instructions were stupid easy and actually were correct.
Seals I bought, fit the 300 series Dometic. Installation instructions on the Amazon page.
Follow these Simple Hassle-Free Instructions:
Step 1: Turn off the water supply.
Step 2: Press down the pedal to hold the flush ball open.
Step 3: Grap the underside of the old seal and pull to remove.
Step 4: Clean the rim and bowl area where the old seal was.
Step 5: Release the flush pedal and let it close.
Step 6: Clean the flush ball.
Step 7: Leave the flush ball closed. Put the new seal in and press down around the entire edge until it is in place.
Step 8: Reopen the flush ball and spread a lubricant in the areas where the gasket will contact the flush ball.
Step 9: Turn on the water supply, add water to the bowl, and ensure that there are no leaks.

Only thing I can add is with the flush ball open, feel around the entire seal to make sure it is seated on the lip. Mine was not in one spot and a little work and it went right in.
