There are a few significant differences in the plumbing systems of the best manufactured homes and the best site-built homes. The methods of construction for manufactured homes causes these differences.
Home builders do not construct mobile and manufactured homes to the same standards as the site-built homes. This is because manufactured home construction has its own standards and regulations. An important factor that adds to the appeal of mobile homes is affordability. Some old mobile homes might have used materials that are on the lower end of quality and cost. However, this is not the case with new mobile homes, which are built from high quality materials.
Understanding the differences between plumbing in manufactured houses and site-built homes can help you deal with simple plumbing issues in manufactured homes. Below, we explain some of the notable differences in the plumbing systems of site-built and manufactured homes.
Plumbing System Differences
An importance difference between the plumbing systems in manufactured homes and site-built homes is the piping material used. Most manufactured homes use plastic water pipes in place of the copper pipes used in site-built homes. While authorities do not approve plastic pipes for use in site-built homes, they do approve them for mobile home use. However, some types of these plastic pipes are prone to leak with age.
Note that modern manufactured homes use PEX or CPVC pipes that can last as long as copper pipes. Therefore, when you shop for a used manufactured home, make sure to check that the home is re-piped with new pipes.
Another important difference in the plumbing systems of manufactured homes is the location of the pipes and the way they are spread across the home. In manufactured homes, the water lines will not come out of the walls, as is the case with site-built homes. Instead, these lines will come up from the floor of manufactured homes.
While trying to change the plumbing fixtures of manufactured homes, you should keep the pipe location in mind. You will need to allow enough space for the water pipes to come up while installing sink cabinets. In addition, you will have to use straight stop valves in place of angle stop valves while connecting the water lines in manufactured homes.
