We all know that plumbers are expensive, so it will be beneficial for you to understand the basics of manufactured home plumbing and do the works on your own. Having a good understanding about the plumbing system may help you to fix the issues as and when they happen, or at least help you save some money while hiring a plumber.
There are a few differences in the plumbing system of manufactured homes and conventional site-built homes. In the case of manufactured homes, the plumbing lines are placed under the home and will be stubbed through the floor of the home; whereas in site-built homes, the pipes will be placed in the walls of the home. It will easy for you to access the pipes in manufactured homes, but the disadvantage is that the plumbing pipes that run under the home are prone to freezing and severe temperatures.
In addition, cleanouts and overflows will not be provided in manufactured home plumbing system like that in site-built homes. This lack of overflows and cleanouts can be a problem while trying to fix blockages.
All home plumbing systems will have three main elements: supply lines, drainage lines, and ventilation lines. Typically, the drainage and ventilation lines will be grouped together, but the supply lines will be separated from them. All these three components of the plumbing system work together and if one party of the system is broken, the complete system will not work.
As said, supply lines will be separated from the drainage and ventilation lines, because they carry water into the home and distribute it throughout the house. The biggest concerns with supply lines are leaks around connections and frozen water lines.
On the other hand, drainage and ventilation lines carry wastewater out of the manufactured home, and use gravity, airing, and traps to ensure efficient waste removal. These lines also keep fumes and gases from building up inside the house. In fact, the drainage and ventilation system can be considered a closed system with negative and positive pressure or vacuum.
Without the presence of adequate positive or negative pressures in the drainage lines to offer vacuum, the system will not work the way it is meant to. As all parts of the plumbing system should work correctly to do its work properly, you need to make sure that there is enough pressure in the drainage system.
