It is true that the majority of people don’t know much about the domestic plumbing system. Proper Home plumbing is the basic need of every home.
The home plumbing diagram tells us how residential plumbing works. It tells us how plumbers often install pipelines inside walls, outdoors and under the ground. This diagram also shows the passage of water through colorful pipes.
It is important to note that all these pipes are not visible. Some of these are underground while some are inside the walls.
Blue pipes indicate a clean water supply that we use for drinking, cooking, and bathing.
Red pipes indicate hot water supply line connected to a boiler or any heating system
Underside grey pipes are for sewer or dirty water
Upperside grey pipes are inserted in walls that allow venting of air and gas to escape through pipes
The plumbing system itself is not as easy as shown in the diagram. Move on to read how it works
How residential plumbing system works?
For residential plumbing, two fundamental systems work at the same time. One is
the domestic plumbing system and other is a sanitary waste system.
Domestic Plumbing System
This system delivers pressurized water into the structure for cooking, drinking, bathing, laundry and so on. These pipelines are shown blue in the diagram.The most common materials used for these piping are CPVC, traditional copper piping, and PEX. This system takes fresh water from
- The main city water system
- Well system
Inside the home structure, domestic water supply further divides into the hot and cold water supply. Coldwater goes directly to tap, fixtures or pipelines. However, hot water first passes through the heating system or boiler then it goes to fixtures as shown in red pipes in the diagram.
Sanitary waste plumbing system or DWV
This system works on the principle of gravity waste elimination system. It removes undesirable waste from home.
- D stands for a drain from, tub, laundry, sink
- W stands for waste that comes from toilet or commode
- V stands for venting that allows air in and out of the system
To understand the venting system consider another diagram.
This system has waste in it that can cause smelly air and gas. Look at black vents under the P trap diagram that stops gases to cause the smell. When pipes are empty without water then air accumulates in it. These vents push air pressure outside. For this reason, these are upward in direction as air moves upward quickly. Venting protects seals from breakage by reducing air pressure.
Plumbing drain line mistakes
Domestic plumbing needs skillful plumbers. In case of any fault, it may cost very high to repair or reinstall the drain. So avoid doing these common mistakes.
- Always pick right drainage fitting. Don’t connect two horizontal pipes with the sanitary tee. It is against the plumbing code. Sanitary tee is not allowed for horizontal to horizontal connections
- Do proper insulation of outdoor pipes as it may freeze in constant cold weather
- Don’t screw plumbing connections more tightly.
- Never use the drain cleaner at the top priority. First, detect the problem
- Always do plumbing tasks with the right tools that fit this job.
- Don’t use low-quality tape or threads,
To avoid plumbing woes, homeowners should keep an eye on certain issues like
- Low water pressure
- Smelly water
- Clog drain
- Valve leakage
- Toilet sounds and many more
All of your plumbing deserves professional care regularly. Don’t hesitate to consult experts if you cant understand the cause of the problem.
By understanding the home plumbing diagram, you will get a deep insight into the plumbing system. It is tricky somehow to handle four types of pipelines in one structure. Experienced Plumbers focus on fresh, hot, waste and vent supply lines simultaneously. Always get assistance from professional plumbers for the residential drain. Poor drainage can bring water damage to your valuable property. I hope that you will structure your house on the same plumbing model as shown in the diagram above.
