The toilet used on the Rialta is one device that seldom gives any problems. It is made by Thetford and is the "Aqua-Magic Starlite" low profile model which is described as a fresh water flush permanent RV toilet. This particular model is no longer shown on their web site so I believe that it is no longer produced but there are other replacement models. It was somewhat unique in that it was the shortest toilet ever made by Thetford at about 11" tall instead of the usual 14" to 17". Thetford does continue to market a riser for this toilet which will bring it up an additional 2-1/2" in height.

When I'm on the road, how do I find a service shop to repair my RV toilet?

Call Thetford's Customer Relations Department at 1-800-521-3032 to find out where the nearest of the 400 Thetford Certified Service Centers (shops which stock parts) are located.

[ Return to FAQ Topics ]

 

What do I do if my toilet bowl doesn't hold water?

This may take a little investigation on your part. If the toilet is new and has never held water, the closet bolts mounting the toilet to the floor might have been over tightened. If this is the case, simply loosen the closet bolt nuts.

If the toilet isn't new, or is new but still doesn't hold water, there may be toilet paper trapped under the blade seal in a ledge of about 1.5 inches. A special tool to clean the groove is available from Thetford (for a price of $5.25 plus $3.50 for shipping and handling; 1-800-521-3032) and some dealerships.

If this doesn't correct the problem on the Aqua-Magic Aurora, Galaxy and Starlite models, you may need to repair or replace the Flushing Mechanism or, depending on its age, replace the toilet. On the Aqua-Magic IV, you may need to replace the Blade Seal.

[ Return to FAQ Topics ]

 

Water constantly runs or drips into my toilet's bowl. What should I do?

Within about 10 seconds after flushing the bowl will normally fill from 1-2 inches to provide a "water barrier."

If the bowl continues to fill with water, the water valve is leaking and should be replaced.

[ Return to FAQ Topics ]

 

What is the cause of a leak behind my toilet after flushing?

Generally, the cause is the toilet's Vacuum Breaker.

For Aqua-Magic Aurora, Galaxy and Starlite, repair or replace the Vacuum Breaker. For Aqua-Magic IV, replace the Float Assembly.

[ Return to FAQ Topics ]

 

What does the Vacuum Breaker do?

The Vacuum Breaker is essentially a check valve or anti-siphon devise, which allows water to only flow one way. It is a plumbing standards code requirement that a Vacuum Breaker must be on all toilets. This prevents waste water from siphoning back into your fresh water.

[ Return to FAQ Topics ]

 

How do I remove my RV toilet from the floor?

Start by turning off the water supply to the toilet (see your vehicle owner's manual for detailed instructions).

The Aqua-Magic Galaxy and Starlite models are mounted to the floor with two closet bolts and nuts. One is located behind the foot pedal and is easily accessed by depressing the foot pedal. Remove the 1/2 inch nut. The other closet bolt is located behind the toilet. To locate it, lift up the seat and cover and remove the access hole cover located on top of the hopper. Using a 12-inch extension with a universal and a 1/2 inch deep-well socket, remove rear nut. Disconnect the fresh water supply line and lift toilet straight up.

For Aqua-Magic IV, disconnect the water supply line from the water valve located on the rear of the toilet. Remove the nuts from the closet flange bolts located on each side of the toilet. Carefully lift and remove the toilet from the closet flange.

Consult your Thetford Permanent Toilet Owner's Manual for more detailed instructions and illustrations.

[ Return to FAQ Topics ]

 

How do I remove my Aqua-Magic IV seat and cover?

The seat and cover must be replaced at the same time.

With the seat and cover in an upright position, quickly push toward the back wall and the hinges will pop out. If the toilet has been installed too close to the wall, it may be necessary to remove the toilet (see the question above and your toilet Owner's Manual for instructions).

To reinstall, place the new seat and cover in an upright position and push in as you push down towards the bowl. The hinges will snap into place.

[ Return to FAQ Topics ]

 

What should I use to clean my RV Toilet?

Your toilet, sinks and showers should all be cleaned in the same way: We recommend using a soft sponge or cloth and a high-grade, non-abrasive cleaner such as Thetford's Aqua-Bowl®.

Do not use a highly-concentrated or high-acid content household cleaner, nor those containing abrasives, such as a scouring powder. They may damage the seals or plastic parts of the toilet, along with the seals on your dump valves.

[ Return to FAQ Topics ]

 

What do I do when I have a warranty claim?

For parts and/or service - including those under warranty - contact a local Thetford Certified Service Center (CSC) or an RV Dealer. Or, call Thetford's Customer Relations Department for information at 1-800-521-3032.

For warranty consideration, parts must be sent to Thetford. Call 1-800-521-3032 for a "Returned Goods Authorization Number" before sending them in. When you call, please have this information available:

  1. Your name and address.
  2. The toilet Model, Part No. and Code (located on the ID labels on the inside of the toilet):
  3. The problem/reason for return.
  4. Proof of date of toilet purchase.

Under the Warranty Program, Thetford replaces or repairs toilets and/or parts, and reimburses for warranty labor.

[ Return to FAQ Topics ]

 

Where is the ID Label located?

On Aqua-Magic Aurora, Galaxy and Starlite models, it's located behind the seat. Best visual access is gained by lifting the seat and lid about halfway up.

On Aqua-Magic IV and Electra-Magic models, the ID Label is located on the center front below the rim of the toilet.

[ Return to FAQ Topics ]

 

Which deodorant product should I use?

It's a matter of personal preference - based on what you're looking for...

If you seek unsurpassed deodorant performance - even in extreme weather conditions - and superior waste digestion, top-selling Aqua-Kem® is your choice. If you prefer a non-formaldehyde product that has excellent odor control, choose Aqua-Kem® Green. If odor control isn't vital and you'd like an enzyme-based product, Aqua-Zyme® is your best bet.

Once you decide on the formula, select which type of dosage is right for you. All three formulas are available in liquid, and all but Aqua-Zyme are available in dry forms. The newest member of Thetford's holding tank deodorant lineup, convenient Aqua-Kem® TossTabs, is based on the Aqua-Kem Green chemistry.

[ Return to FAQ Topics ]

 

Can I use household products to deodorize or clean my RV's sanitation system?

No! Use only RV specific holding tank deodorants and cleaners.

"Homebrews" (a single or combination of household products) can damage your toilet - even possibly forming a dangerous, explosive mixture - and should never be used!

[ Return to FAQ Topics ]

 

Are formaldehyde-based holding tank deodorants banned in some states?

No. Some campgrounds restrict its use, but this is the campground management's individual decision - not based on a state (or federal) law. Generally, a campground bans the use of formaldehyde due to misinformation about its treatability and biodegradability.

[ Return to FAQ Topics ]

 

Are formaldehyde-based deodorants treatable in waste treatment systems?

Yes. They've been studied extensively, and independent studies substantiate that formaldehyde is readily biodegradable and treatable as long as the treatment system is properly sized and operated (for treating holding tank waste).

RV holding tank waste is so concentrated (compared to household waste), it can cause problems in undersized or improperly maintained treatment systems even if no deodorants are present.

[ Return to FAQ Topics ]

 

Should I use a special RV tissue?

Yes. Rapid breakdown of toilet tissue helps prevent clogs - an issue when dumping an RV holding tank.

Most household toilet tissue manufacturers are unconcerned about fast disintegration because:

  • Many times more water is used in flushing a household toilet than a RV or portable toilet.
  • Most households are connected to a city sewer with 3-foot diameter lines, while a RV's highly-concentrated waste is emptied through just a 3-inch diameter opening.

  • [ Return to FAQ Topics ]

     

    Why are specialty products sold separately instead of being included in the deodorant products?

    Because they aren't needed each time the deodorant is added.

    Thetford's Drain Valve Lubricant, for example, soaks into the seals of the valve, providing lubrication for several dumpings of the holding tank.

    Adding it to the deodorant would increase the price of that deodorant and force the consumer to use an additive that is not necessary each time the deodorant is changed.

    [ Return to FAQ Topics ]

     

    How are Thetford's holding tank products developed?

    Thetford has the RV industry's only full-time chemistry staff dedicated to recreational vehicle sanitation products.

    That Chemical Engineering staff, based in Ann Arbor, Mich., starts by researching new products. Often, new product ideas come from RV'ers seeking "a better way."

    The staff also formulates the new products, which then are extensively tested - often over many years in "the field." Thetford takes the time necessary at the testing stage to assure that a product is "as good as it can be" prior to its release to the market.

    [ Return to FAQ Topics ]

     

    Some products claim to be a top deodorizer and waste digester, while also lubricating valves, and cleaning sensors and the holding tank. Do these products really do all this?

    It's easy to make product claims - far tougher to live up to those claims.

    What you describe may be a case of the old adage "If it seems too good to be true, it probably is."

    Be skeptical of holding tank deodorants claiming to "do it all" - especially if they "do it all" via a relatively small tablet and/or dosage and for a small price.

    (By the way, Thetford "marketing claims" are reviewed - and substantiated - by the Chemical Engineering staff prior to packaging production.)

    [ Return to FAQ Topics ]

     

    Why are label "warnings" on Thetford's packaging so prominently displayed?

    We're glad you asked because package "warnings" are a safety issue the people at Thetford feel strongly about.

    After all, Consumer Product Safety Commission regulations exist to protect the consumer, something we're committed to.

    As part of that commitment, Thetford has a chemist whose area of expertise is governmental regulations.

    Through her efforts and others on staff, Thetford is careful to strictly adhere to CPSC regulations. Other companies may not be as careful - which may explain why the product "warnings" on their packaging aren't as prominent.

    [ Return to FAQ Topics ]

     

    What happens if deodorants freeze?

    Aqua-Kem is not "stable" in long-term freezing conditions. It will turn to a partial solid that doesn't readily dissolve. It can still be used, but you may notice a slightly reduced deodorant performance.

    All of Thetford's other liquid products will freeze, but are fine once thawed. And, the dry products are completely stable in freezing conditions.

    Extremely high temperatures can have an adverse effect on all products. It is best to store the products in standard room conditions.

    [ Return to FAQ Topics ]

     

    Can I safely dump my holding tank in my home septic system?

    Yes - as long as your septic system is fully functioning, adequately sized and properly maintained. If you do, it's important to use only the recommended amount of deodorant in your holding tank and only empty when the tank is full.

    Also, because holding tank waste is very concentrated and breakdown takes longer, we recommend you dump only one RV holding tank in a home septic system per week.
