How can I locate the Dometic/Sealand model number of my toilet before ordering parts?

To locate the model number of your toilet:

For a step-on foot pedal toilet, the model number is underneath the shroud that wraps around the base.
For a tall base toilet mounted directly to the floor, the shroud is held together by a Phillips-head screw.
For a short base toilet mounted up on a step, there is a clear rubber tab behind the foot pedal holding it together. Once the shroud is removed, the sticker with the model number will be on the base itself.
For electronic toilets, the sticker is located on the back inside wall of the porcelain.
Once you have a model number go to Dometic Parts diagrams. Search for your model number in the list. Next to the model number click on Parts Diagram PDF/See parts. You will be able to view a full diagram of the toilet by clicking on Parts Diagram PDF. The See Parts link has links directly to the parts available for purchase.

How can I identify the configuration of my Dometic/Sealand pump, tank, or vacuum system?

We have created a Find Your Vacuum Generator, Tank, or Pump page with photos of each type to help you determine which one you have.

In addition, most units have a sticker on the tanks or motors indicating the voltage and system type.

If you are still uncertain of what you have, take a photo of the complete unit and email or text it to us at 954-540-9733. We will help identify it for you.

What should I do if I can't find a part on your website?

We have a Dometic/Sealand Parts Diagrams page with diagrams of all the toilets and systems with links to the specific parts available for purchase.

If you don't find the part you're looking for on our website, contact our team by sending us an email at info@environmentalmarine.com or give us a call at 800-522-2656 (or 954-522-2626 for international customers). You can also send us a text with the parts you’re looking for at 954-540-9733. International customers can also text us at the same number using WhatsApp.

How do I know which bowl seal to use for my Dometic/Sealand toilet?

The correct bowl seal depends on the model and age of your toilet:

All foot pedal vacuum toilets should use 385311462 seals.
All foot pedal traveler toilets can use 385316140, but newer models without drain holes in the bowl (2001 or newer) also use the 385311462 seal.
The part #385310677 seal is no longer available, and you should use the 385311462 instead.

How do I know which Dometic/Sealand Toilet Seat and Lid assembly to order for my toilet?

You will need the model # of the toilet to determine which toilet seat and lid you will need. (See how to locate the model number above)

Once you know the model number, we have created a chart that will help you determine which toilet seat is the correct one called Find Your Dometic Toilet Seat.

If you still are not sure which seat and lid you need, take 2 photos, one a side view of the complete toilet, and the other a top down view of the complete toilet and email to info@environmentalmarine.com or text it to us at 954-540-9733. We will help identify it for you.

What is the difference between a Dometic/Sealand vacuum generator pump and a discharge pump? (Or why can’t I use a TW pump in place of an SW Pump or JW Pump?)

The SW Pump is a vacuum pump with a black housing used with the original Accumulator Tank, VG2, and VG3. The JW Pump is a vacuum pump with a white housing used on the VG4. The TW Pump is a discharge pump with a white housing used to discharge black water from the holding tank.

The TW pump was designed to discharge only, it was not designed to sustain vacuum. If you try to use a TW pump in place of an SW or JW pump it may work for a short period of time but soon it will not create vacuum and will need to be replaced with the proper pump.

What size duck bills does my Dometic/Sealand vacuum generator pump or discharge pump use?

The SW Pump uses 1-1/2” duckbills. You will need 2 packs (2 in each pack) for each pump.
The JW Pump uses 2” duckbills. You will need 1 pack (4 in each pack) for each pump.
The TW Pump uses 1-1/2” duckbills. You will need 1 pack (2 in each pack) for each pump.

Are the old Leeson motors still available?

Unfortunately, the old Leeson motors (Part #310245 12 Volt and #310246 24 Volt) are no longer available. The type of motor sat diagonally on the vacuum pump. You will need to upgrade using the Dometic Whisper Motor Upgrade Kit, which includes a new motor, bellows, clamps, and O-rings. The upgrade kits are 385311423 for 12 volt and 385311424 for 24 volt systems.

Is there a basic rebuild kit for my vacuum generator pump?

Yes, we have numerous rebuild kits but the kits we sell the most are:

KS000B - This is the basic rebuild kit for the SW Pump and the TW Pump
KS000J – This is the basic rebuild kit for the JW Pump
385311423 – Purchase this if you have an old-style diagonal 12 Volt motor (Leeson motor) on your vacuum Pump. Keep in mind you will need to purchase duck bills separately based on the style of pump you have.
385311424 – Purchase this if you have an old-style diagonal 24 Volt motor (Leeson motor) on your vacuum Pump. Keep in mind you will need to purchase duck bills separately based on the style of pump you have.

What cleaners are safe for my marine toilet system?

Many of our customers mistakenly think they can use household cleaning products to clean their marine toilet. These products can quickly ruin various components in marine toilet systems. Do not use them!

Dometic has a new product called Max Control Natural that both eliminates odors and digests waste. It’s a completely safe, natural and biodegradable bacterial/enzyme formulation that can go directly into the toilet, vacuum generator, and holding tank.

Another product we use regularly here to clean vacuum generators is the Bright Bay Descaler. We immerse the entire vacuum generator into a plastic tub using a 10 to 1 gallon water ratio to Bright Bay Descaler concentrate. We've found the longer it sits the better it works.

Both of these products are safe for all system components as well as environmentally safe, using natural enzyme producing bacteria to break down waste and scale.

What is the replacement for the Sealand SaniGard Vent Filter?

The Dometic Eco Holding Tank Vent Filter is the replacement for any existing SaniGard Vent Filter. It comes with fittings to accommodate any 5/8”, 3/4”, 1”, and 1 1/2” hose sizes inside diameter. (include link to 309311004)
