PROPER Under Slab PLUMBING | Is $elf Building Worth It? | Ep 14

Hey, everyone! Welcome back to Mr. Post Frame. I'm excited to dive into today's topic with you, we're exploring the question: "Is self-building worth it?" Today, our focus is on plumbing – an essential but often overlooked aspect of construction.

How to plumb your house

Plumbing may not sound like the most thrilling subject, but trust me, it's a crucial part of any building project. Whether you're building a cozy cabin or a sprawling barn, getting the plumbing right can make a world of difference.

In our series, we're delving into various aspects of self-building, and plumbing is definitely a hot topic. From laying out pipes to choosing the right materials, there's a lot to consider. And that's exactly what we'll be discussing today.

DIY plumbing

But first, let's address the elephant in the room: DIY versus hiring professionals. Plumbing can be a contentious issue, with some arguing that it's best left to the experts. However, we've found that with the right guidance and attention to detail, DIY plumbing can yield excellent results. At Mr. Post Frame, we specialize in post-frame construction, and plumbing plays a significant role in our projects. Whether it's routing pipes under the slab or deciding on venting options, we've tackled it all. And today, we're sharing our insights with you.

One of the key decisions you'll face is whether to route pipes under the concrete slab or in the attic. It's a choice that can impact the efficiency and aesthetics of your plumbing system. Personally, I prefer running pipes under the slab for a clean and concealed look. But plumbing isn't just about aesthetics; it's also about functionality. That's where modern materials like PEX come in handy. With its flexibility and durability, PEX makes installation a breeze – even for DIYers.

Plumbing a home step by step

In our plumbing video, we walk you through the process step by step. From planning and layout to installation and venting, we cover it all. And trust me, attention to detail is key. A small mistake now could lead to big headaches later on. Of course, no discussion about plumbing would be complete without addressing the issue of venting. Proper venting is essential for preventing sewer gases from entering your home and ensuring smooth drainage. It's a topic we take seriously, and you should too.

So, whether you're planning to DIY your plumbing or hire a professional, there's a lot to consider. But with the right approach and knowledge, you can tackle this challenge head-on. And who knows? You might just surprise yourself with the results.

In conclusion, plumbing may not be the most glamorous part of construction, but it's undoubtedly essential. So, if you're embarking on a self-building journey, don't overlook the importance of plumbing preparation. Trust me; it'll save you a lot of headaches down the line.

I'm not saying I've never violated code because I have. I've intentionally violated code, so if you're a stickler for codes, that's just the way it is. However, if you think about it, the code sets minimum standards, and some provisions are based on the smallest size vent or drain pipe. For instance, with a washing machine drain, there must be a minimum 18-inch drop pipe and a 4-inch leg. But if you're using a sufficiently large pipe, the risk of siphoning is negligible, so you might not need to adhere strictly to these dimensions.

I'm not suggesting disregarding the code entirely, but there are aspects of it that might not be essential for the functioning of your house. Similarly, electrical codes, such as requiring outlets every 12 feet along a railing, can seem excessive at times. I've had to comply with such requirements even when I disagreed with them, simply because it's the code.

Building code serves to establish a baseline standard, not necessarily to ensure the highest quality. Furthermore, interpretations of the code can vary among inspectors, which can be frustrating. Inspections ensure compliance, but they don't guarantee perfection. It's important to keep in mind that everyone involved in the process, including inspectors, is human and has their own perspectives.

If you're considering a DIY project, choosing a location with fewer restrictions can make the process smoother. However, regardless of the regulations, it's crucial to ensure that everything functions properly. Prior to covering up any installations, whether it's plumbing or electrical work, it's wise to double-check everything. Even if inspections aren't required, having someone else inspect the work can provide valuable feedback. For instance, pressure testing plumbing lines is a common practice to ensure they're sealed correctly. Personally, I've pressure tested my supply water lines to 50 lbs of pressure for a few hours to confirm their integrity. Taking such precautions can prevent future issues and ensure that your home functions as expected.

When it comes to plumbing, there are various ways to design water supply systems. I prefer a home run system with a manifold in the utility room for easy access and maintenance. Planning the layout of water lines based on the proximity of fixtures can simplify installation and reduce the risk of pressure drops. Running water lines under the slab is generally safe if done properly. Proper preparation of the site, including well-compacted soil, minimizes the risk of settling and potential damage to the lines. While sleeving the lines for added protection is an option, it may not be necessary if other precautions are taken.

In conclusion, while building codes provide important guidelines, they may not always align with practicality or efficiency. It's essential to strike a balance between compliance and functionality, and to take necessary precautions to ensure the integrity of installations. That wraps up our discussion for today.
