Principles of Plumbing Services in Buildings

The following factors are to be considered while designing plumbing services to buildings:

1. All foul and waste matter should be removed as quickly as possible.
2. All possible passage of gases, odour or vermin from pipes and sewers into the building should be prevented.
3. All drainage pipes should be airtight, gas-tight and strong enough and durable to withstand the corrosive action of liquid wastes.
4. All pipe joints (both water supply and drainage) should be leak-proof and strong and durable.
5. The entire network of pipes should have ample means of cleaning and removing obstructions.
6. Every care has to be taken to check and rectify all possible air-locks, siphonage, under deposits and obstructions.
