Prevent poison sewage gas in the bathroom.

[paulpaul]

I have lived in Thailand for several years now in many different places and I have often had problems with bad smells in the bathroom and waking up in the morning with headaches and nausea. Since observing buildings under construction I now understand the problem. U-traps or U-bends are almost never installed in the drainage in the bathroom. I have noted that even hospitals don’t install them. U-bends are required by law in western nations with good reason. The U-bend holds water and prevents the sewage gas generated in the septic tank from forcing itself back up the pipe and into your bathroom. An exhaust pipe is also necessary on the tank or drain pipe outside the building to vent these bio-gases which build up under pressure in the tank. This bio-gas consists of methane, hydrogen sulfide, carbon dioxide and bacteria spores and with cleaning it can be used in a gas stove for cooking or in an alternator for generating electricity. Vented into the home however, it can lead to headaches and nausea and can deteriorate your health over time. In confined spaces with poor ventilation it could even result in death, especially in young infants and old people and those who are already ill. The danger is when you are asleep; hydrogen sulfide kills the sense of smell and is also poisonous.
Normally the U-bend is fitted at the beginning of the drain pipe under the shower; existing shower drains in concrete could be modified by putting the U-bend at the end of the pipe inside the septic tank. A vent must be fitted to the tank which goes up to the roof to release the gas above the house, preventing bad smells around the home.
If you are a home owner, a businessman, an architect or a builder, I urge you to plan ahead and install these cheap pieces of plastic that will keep your home or business smelling fresh and clean and protect you and your family or your employees and customers. And if you have tenants, they may be encouraged to stay longer if you have the cleanest smelling accommodation they have stayed in.
I also urge the government to conduct a public education program on hygienic building practices and please modify hospitals and public buildings where possible.
I am sure that this widespread problem has had a serious impact on public health and eliminating it would improve the general health of the community and save a lot of medical expense as well as heartache. Prevention beats cure every time.

I noticed the smell too but some of the newer buildings don't have the smell. Is it not in the building code?

I guess you should leave your bathroom windows open all time, if you have a window.

You should install a exhaust fan in your bathroom and keep opened windows of the bathroom after use. It happens in sewerage that gases are produced but a good exhaust system can solve this problem.
