Is plumbing recommended for exterior walls?

When it comes to home construction and renovation there are numerous rules to consider. However, more and more people change the old rules as experts look for ways to proffer solutions to the problems that contractors faced before.

The same applies when it comes to plumbing. While there are dos and don’ts that plumbers follow, some opt to do the unconventional means against what everyone else is usually doing. One question that the experts get – can plumbing be on an exterior wall?

Is plumbing recommended for exterior walls? 

Although plumbing can be placed on exterior walls, it is not recommended. Having any waste and venting pipes, as well as main waterlines placed on an exterior wall can have problems during the winter. As for waste and venting lines, the possibility of freezing is not as high. But running them through a wall can still cause cold spots to form, areas where heat can easily escape. This also means that insulation will not be applicable for that specific wall.

When it is necessary

Sometimes, running any plumbing system on an exterior wall may be necessary. Even though there are risks that come with placing plumbing on external walls, there will always be ways to make it effective.

1. Before the plumbing lines are set, insulate and put the drywall in. Fur out an inch and a half and use this space for the waterlines. This will allow you to place the plumbing system without making the wall look bad.
2. If the exterior wall is just about to be added, or the entire exterior of the structure is being redone, you can also opt to place insulation on the wall exterior. After this, you can simply run any kind of plumbing within the walls. This method can make your home more energy-efficient.

Your plumber may opt for these two solutions or come up with a solution of their own. There are ways to get the plumbing job right, and the more experience a plumber can think of more ideas to make it work.
