A septic tank is built under the bathroom, and all of it is sealed with cement

Singlely, from the cast iron pipe, as long as there is no external force and no cracks, it is fine, and the cast iron is very corrosion-resistant

It is best not to put the toilet on the top of the septic tank, especially if the space is limited, you should consider whether it will affect the cleaning work in the future.

Dig a three-level septic tank, the moment distance from the bathroom to the septic tank is about 30 meters, and the drainage pipe needs 4 elbows through the septic tank, which may be plugged! It is recommended to use a 5-inch pipe for the pipe, and it would be better if the elbow could be less!

When doing a manure tank, you can choose three septic tanks, which are composed of three connected pools in the middle, and the connection is mainly based on the principle of anaerobic fermentation, middle layer fecal and parasite egg specific gravity is greater than the specific gravity of the general mixture and easy to precipitate, the general fecal can be transported to the next layer after more than 30 days of fermentation and decomposition in the pool, and the manure liquid flows from 1 pool to 3 pools in turn, so as to achieve the purpose of precipitating or killing parasite eggs and intestinal pathogenic bacteria in the feces, the third pool of fecal liquid will become high-quality fertilizer, This will achieve great results.

Summary. The household septic tank is 20 meters away from the bathroom, and the pipes may be blocked. It doesn't matter how far this septic tank is from the bathroom, it is mainly related to the kitchen oil, which is easy to clump and block the pipe when it is cold underground. >>>More
