Thetford Aqua Magic Style ii issue

[SMR]

Sometimes after we flush, the toilet will make a gurgle sound and some water drips into the toilet bowl.
About 2 weeks ago we were at a campground where the water pressure was low when we arrived and in the morning it was much higher and that is when the issue started.
High enough I put on my pressure regulator.
Any thoughts on what I should look at?
Thanks

The water supply that swishes the bowl might be clogged with lime deposits? Limeaway? Other than that thought, the jokes could flow…

Gurgling when flushed is usually a sign of a near-full waste tank or a clogged tank vent. The water flowing into the black tank displaces enough air that it pushes some air & water back into the bowl, making a gurgle or sputtering noise.

In a gravity toilet, water pressure only affects the water going into the bowl as you flush. No gurgle.

Are you saying the gurgle & dripping happens after the flush cycle completes (flush valve closed)? High pressure can sometimes cause a leak at the water inlet valve and water might dribble into the bowl even after the flush pedal is released and the valve closes. Lime or other minerals in the fresh water can make the inlet valve stick slightly open. You could take it out and soak in a vinegar solution to clean it up. Or replace the valve.

Not from the black tank, it's the fresh water coming in. It is making noise when the water drips out, DW said it sounds like someone passing gas and I said sure blame the toilet now that we don't have a dog....

You can get a kit to replace both the inlet valve and the bowl seal for around $20. I'd probably do that first, eliminating some of the more common problems with those toilets.

I ordered the parts. Should have them tomorrow.

dump the Aqua Magic and get a Dometic that really flushes. Want a new Aqua Magic I have one I took out of my new 5W never been used.

Perhaps lack of using the pressure regulator created the problem and ruined the water valve? I think I read where RV plumbing is factory-tested @ 60 psi. Gary will know the facts.

Does Dometic have models that use standard residential toilet seats?

Sealand, the former brand name for the now-Dometic toilets. Don't know if that feature was retained, though.

Much higher than that. I've forgotten the exact psi, but I think RVIA standards requires a minimum pressure test of 85 or 90 psi and rumor was that most manufacturers exceeded that. But the pressure test is probably done before all the appliances are installed. That's how it is done in residential plumbing, cause it is of little value to discover a leak after the plumbing is buried in wall or floor..

While it may have been increased, a long time back I was able to see the standard and it was 100 psi.

The reason I ask, is that I have a toilet seat riser and safety rails installed on my Aqua Magic Style Plus, and that requires a standard residential seat configuration.

Thanks for updating me Kirk!

I was thinking that way too, Kirk, but I also remember that back in the day Fleetwood claimed they tested at 100 psi and that was above RVIA spec. But that was long ago now. In any case, well above 60 psi, so have no fear about regulating pressure at 60-65 if you like.

yes, it comes with a wooden slow close
