I've had several guests at RV parks comment on the automatic refill toilet in our 1999 Winnebago Chieftain. I've even had my RV tech tell me that only very high end RV's have auto refill toilets. I've even had to prove it using the owners manual when the tech suggested the valve was malfunctioning and might flood the RV one day.

What's the big deal about making a auto refill toilet that prevents them from being in every rig out there? It seems like pretty simplistic stuff.

Humm, I donno. Every one we've had does that. Remove foot from pedal, and bowl fills with water to a certain point. I've talked to some RV technicians that should become members of irv2.com and learn things. Like the one who said to never use the black tank flusher/rinser with the valve closed. He said it would blow up the tank from the pressure_??? Wonder what he thinks that vent on the roof does.

Your RV Tech thinks they sit empty and dry ? You might have the wrong tech.

No, he and several others are used to using the foot pedal to manually refill the bowl.

My 01 Chieftain and 08 Bounder had auto refill toilets.

Sure, just what we need, a toilet full of water while going down a mountain.

Enough water to flush is not a " toilet full of water ". I've traveled over every mountain range in the US and never spilled a drop

Just how much water does yours "auto-refill"? Standard rv toilets have put a few inches of water in the bowl after a flush for at least the last 20-25 years. If you want or need more, you use the manual lever (foot or hand), but the basic water level is automatic.

Can you tell us the make & model of this high end toilet you have? As far as I can determine from the '99 Winnebago brochures, the Chieftain (and other Winnie coaches) came with typical RV toilets, albeit the nicer porcelain models. The Chieftain and Adventurer both..

It adds two inches of water. From the owners manual.

My toilet is electric. Thetford Aria Deluxe Classic

It has 2 buttons, one to flush and one to add water. There is also a switch in the back of the toilet that controls water level, one setting fills the bowl with ~2" of water, the other is residential which fills the bowl about 1/2 full.

I had to change the gaskets and board in mine about ~3 years ago. The original board you could hold the fill button down and it would fill continuously without stopping, so say something fell against the button it would overflow the bowl.

On the new board it limits the number of pulses to 10 and then stops, you have to release the button and then you can add more. Of course if you have a smart cat who likes to watch the toilet flush you might be in trouble.

That's no different than most RV toilets, whether Thetford or Sealand/Dometic. My old '96 Southwind had a Thetford toilet that did that. I think your RV tech has rather limited experience with RVs.

Actually, I'm pretty sure that it's simply that the flow of water from the rim at the top just runs down the inside of the bowl when the valve closes. The input flow stops, but the water is already in the rim.

The electric models may be handled differently.

Yeap, nothing magical about how it works in a gravity toilet. Just enough water flowing in its internal lines to put a couple inches in the bottom after the bowl valve closes. The water inlet valve closes a moment later than the bowl valve.

Macerator type toilets are a different matter - they have their own pump and electric controls.
