Separett Villa 9215 Composting Toilet - Frequently Asked Questions

How often should the toilet be emptied?

If four people are using the toilet daily, a container will last about 3 weeks. It depends on toilet paper usage. The full container can be composted on your property.

How is it possible that the container with solids rarely needs emptying?

Since urine (85% of waste volume) is diverted, the storage capacity for solids is much greater. You only need to empty the container based on the number of users.

Are there unpleasant odors indoors?

No. As long as the fan runs continuously and the venting pipe is properly sealed, odors should not be a problem. Clean the fan filter and insect net regularly.

Are there unpleasant odors outdoors?

No. Urine and feces are separated, preventing latrine odors. Venting pipe placement can minimize any temporary odors right after usage.

Are there unpleasant odors from the leaching bed/soak-away?

No. The urine is absorbed into the ground and harmlessly percolates away, eliminating any odor.

Are there unpleasant odors from the Separett Ejektortank?

No. The urine odor is directed through the toilet ventilation system, diluted by air, and is undetectable by the time it exits outdoors.

Must the urine waste pipe contain a p-trap?

No, since any faint odor from the urine is ventilated out via the venting pipe, thanks to the continuous fan operation.

Are flies a problem with these toilets?

No, fly problems are rare, especially if the fan is left on, as the venting screen keeps them away.

Should the fan operate continually?

Yes, keeping the fan running dries the interior and extends its life. If it needs to be turned off, place the lid on the container.

Which is the best method for routing the venting pipe, through the roof or straight through the wall?

It is easier to route the venting pipe straight through the wall. Through-the-roof installations are more complex and harder to seal properly.

How much airflow does the fan create?

The airflow depends on the length of the venting pipe and the number of bends it has, so there is no simple answer.

Is an additional fan needed if you have a shower in the same room?

No. The bathroom ventilation can be handled by the continuous operation of the toilet fan.

Does the venting pipe need insulating?

No, the Separett Villa has a condensation collector, so insulation is not required.

Can the ventilation be run through a chimney stack?

No, it's not recommended. Moisture can damage mortar joints, and the plastic pipe may melt in the chimney stack.

Where do I lead the urine?

You can route urine to a grey water system, a simple leaching bed/soak-away, or a tank like the Separett Ejektortank.

Can I extend the urine outlet?

Yes, extending the hose is possible, but using a pipe is recommended for better drainage. Indoors, use a 32-40 mm pipe, and outdoors, use a 50-75 mm pipe.

Does the urine waste freeze in the winter?

No, under normal conditions. Ensure the pipe slopes downward continuously and use at least a 50 mm pipe outdoors. You may also insulate outdoor pipes.

How can I make a simple leaching bed/soak-away?

Dig a 2' x 2' x 2' hole, fill it with rocks, and cover it with landscape cloth. Ensure proper routing for the urine outlet. Check with local authorities if unsure.

Am I allowed to connect the urine waste hose to the greywater system?

Urine is sterile, but local regulations vary. Check with local authorities before connecting it to the greywater system.

How steep a drop must the urine waste pipe have?

The pipe should drop continuously to prevent blockages from urine salts or ice. A steeper drop helps avoid buildup.

Is it possible to reduce the risk of urine salt deposit build-up in the urine outlet?

Yes, rinse the urine basin with water after each use, and you can use Separett Bio Drain Cleaner tablets to prevent salt buildup. Use a drain cleaner if blockage occurs.

Is it possible to lengthen the hose on the Separett Ejektortank?

Yes, you can extend the emptying hose up to 20 meters, but only with a '¾' hose. Avoid using garden hose adapters as they may clamp too tightly.

Do I ever have to add anything?

Some users add Separett Absorb inside the container to keep the contents dry and odor-free.

Which type of toilet paper should I use?

You can use regular toilet paper in the Separett Villa.

Should I throw toilet paper in the container?

Yes, toilet paper helps keep the contents dry and makes them easier to handle during disposal.

Does the toilet function in cold rooms?

Yes. Cold temperatures may slow down composting, but it will resume when temperatures rise.

Can I use compostable waste bags?

Yes, we recommend using Separett Compostable waste bags, which are designed to break down slowly in compost conditions.

What should I do when the container is full?

Cover the container with the supplied lid, remove it, and add soil or composting material. Let it sit for six months before using it on non-edible plants.

Can the toilet tolerate freezing?

Yes, though composting may slow in freezing conditions.

Does the toilet need regular servicing?

Yes, you need to regularly clean the insect net and the fan filter to ensure proper function.
