Simple tips on how to avoid defrosting the toilet bowl and sink siphon, if you do not heat the summer cottage in winter

For many, the dacha is comfortable as a full-fledged country house. Inside there is a bathroom, shower or even a bathroom with a drain into a septic tank or cesspool. But it is operated only in the warm season, and in winter there are arrivals. Warming up a small area when visiting is not a problem. But what about the sewer system? The odor trap can freeze and tear plastic pipes. Or how to protect the toilet from defrosting? If the water is removed from the system, then an unpleasant odor will penetrate into the room from the septic tank.

V this article considered models of dry siphons. But since they are interlocking elastic flaps, the tightness of the system may be impaired in case of contamination.

I suggest that you familiarize yourself with the tips that were offered by the readers.

1. If you install a ventilation pipe in the septic tank, which will be higher than any connection point of the bathroom in the house, then this will create an exhaust hood in the right direction. The odor trap is drained and air circulation will be in the direction from the house to the inside of the septic tank and then up.

The decision is controversial and there is no guarantee whether it will work in winter. Some more reliable way is needed.

2. You can simply drain the siphon and plug the drain hole in the sink with a rag. With a flexible siphon (odor trap), this is easy to do. But what about the toilet, shower or bath? You can't just remove water from them.

3. Many readers wrote that they pour an anti-freeze liquid for a car glass washer into a siphon or hydro-auto. 5 liters of capacity is quite enough, perhaps even more than once. It is better to first somehow pump out the water from the toilet, so as not to lower the concentration of "anti-freeze". But the fact is that the methyl alcohol contained in the “non-freeze” evaporates. During the winter, its concentration will drop and the rest of the water will freeze. This is a decision if you are absent from the country for no more than 1-2 weeks.

You can dissolve table salt in the anti-freeze container. This will extend the term of her work. Someone simply pours saline water solution into siphons and toilets. Up to -5 g with sufficient concentration should help. In the western regions of the country, the temperature in the house will not drop below. It is also advised to put logs in the toilet with water and salt. What is the protection mechanism in this case?

4. To avoid evaporation of the anti-freeze liquid, inexpensive automotive antifreeze or antifreeze (or their concentrates) can be used instead. Make its freezing point below -50 gr. and then defrosting the toilet is not scary even in Siberian frosts.

Yes, it is more expensive than non-freezing liquid, the price is about 100 r / l. But if you do not plan to use the summer cottage for a long time, then it is justified.
