Toilet Prep for Long Term Storage?

What do you all do to prep the toilets for long term storage? We will need to leave our RV in storage for 4-5 months and want to make sure the toilets are in good working order next time we hit the road. Please advise.

The longest we've gone is maybe 2.5 months and just leave it with water in it. It still had water in it when we used it again.

Other than leaving water in the bowl, we don't do anything extra. When it's winterized, and it can be for 5-6 months, we drain the bowl and that's it.

Look in the manual for your Dometic Macerator Toilet. All storage procedures are in the manual. From memory, anytime the toilet is not going to be in use for longer than two weeks Dometic recommends that your pour 4oz. of laundry detergent into the bowl and flush 5 times in the full flush mode. Then turn off the water and flush 3 times. This is to minimize the water in the bowl, there’s virtually none left, and to protect the seals of the motor.

If in freezing climates then you also have to winterize the toilets. As I stated, this is from memory, so check your manual.

Do this every year, clean it, flush it, and forget it.

We have one gravity and one macerator. During spring thru fall when temps will stay above freezing we just leave water in the bowl. I do flush the macerator several times to be sure the grinder is cleaned out as much as possible. For winter they get the pink juice and I make sure the bowls have some in them.
