Plumbers are expensive, so it’s beneficial to understand the basics of manufactured home plumbing and do the work yourself. Understanding your plumbing system may help you to fix issues as they happen. Even if it doesn’t, it could help you save some money before hiring a plumber.

Plumbing In A Manufactured Home

There are a few differences in the plumbing system of manufactured homes and conventional site-built homes. For a manufactured home, installers place the plumbing under the home and stub it through the floor of the home. For a site-built home, installers place pipes in the walls of the home. It is easy to access the pipes in manufactured homes, but the plumbing pipes under the home may be vulnerable 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 have three main parts: supply lines, drainage lines, and ventilation lines. Typically, installers group the drainage and ventilation lines together, and separate the supply lines. These three components work together—if one part of the system breaks, the system will not function.

Supply lines remain separate from the drainage and ventilation lines, because they carry water into the home and distribute it throughout the house. Supply lines may leak around connections and can freeze in sub-zero temperatures when left unused.

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.
