why is it important not to pour things other than waste, water down the drain.
The carry oxygen and other nutrients to the skin and carry waste products away from the skin, among other things
No.
Drain, Waste and Vent System. It is all of the Drain and Waste piping and their associated vent piping
Bcoz waste water contains toxic metabolites,as the water comes from the industries etc.it contains harmful substances,if waste water is not poured down the drain it will effect the our surrounding and causes many diseases.it also contains harmful bacteria
because then the water will get polluted and animals will die.
We aren't the world survived, even thrived without us. We are important to each other- our family, our pets, etc.- but we are not overall important. We are not as important as a worm is to a few baby birds or how important other animal's waste is to that worm and meat is to those animals and plants are to other animals and sunlight is to those plants. The world cantsurvive without those things, but it can survive without us.
Waste products can harden and can block the open drain.
Depends on local codes
Wouldn't recommend it as things may back up in the drain line. 4" line is the norm ... you want to get rid of waste, not keep it around longer.
Own waste line 2" (Shower) 11/2" waste tub and both need to be trapped and vented
yes it is. if you do dump waste your killing the environment plants and other living things will start dying .
Conservation is important because if you do not conserve things you can waste a lot and it can pollute the community. You can run out of supplies quickly in a community if you are not careful in conserving things.
