Real Plumber Reacts to a NON-Plumber’s Work | Part 2. Sometimes, you come across someone who decides to tackle a significant plumbing renovation on their own—often without formal training or years of experience. While bold do-it-yourself energy can be admirable, it also sets up plenty of potential challenges. In this post, we’ll explore a scenario where a self-taught individual and his friends embark on a substantial re-piping project. We’ll break down what they did well, what to watch out for, and how an experienced plumber might approach the same tasks.
If you’re curious about plumbing renovations, re-piping, or turning a basic room into a full bathroom, you’ll find plenty of valuable lessons here. We’ll follow this young renovator’s process step by step—from the unexpected costs that pop up when you’re “just one part short,” to the intricacies of removing old galvanized pipes. Whether you’re a DIY enthusiast considering your own plumbing makeover or simply someone who wants to understand the hidden complexities, read on. You might just learn how to avoid some common pitfalls and how professionals think about each phase of the job.
A Quick Overview of the DIY Remodel
The individual at the heart of this renovation took a den (an old sitting room) and decided to convert it into a new bathroom. The original professional bid for this project was over six figures, so the renovator believed he and his buddies could do it for less than half that amount. Ambitious? Absolutely. But for anyone who has ever taken on a big remodel, there’s always a risk of oversimplifying the workload—and underestimating costs.
Gutting the Space and Shifting Walls
One of the first major tasks they tackled was tearing out an existing window and shifting walls to re-size the room properly for a shower, sink, and toilet. While framing and carpentry aren’t purely plumbing tasks, they do impact how water lines, drains, and venting will be run. Setting walls in the right place ensures you won’t have to redo or extend piping in awkward ways later on.
Key Takeaway for DIYers
-
Plan the final layout first. Before you begin demolition, make sure you know exactly where fixtures like the shower and toilet will be. This reduces the chance you’ll have to add joist or stud modifications down the line.
The Nightmare of Old Galvanized Pipes
A major theme in this remodel was dealing with decades-old galvanized water lines. Galvanized steel, once a go-to material, is notorious for corroding from the inside out. Over time, rust and sediment form thick deposits inside the pipe walls, reducing flow to a trickle. This is often why you see homeowners complaining that they “have to wait forever for hot water” or “the pressure in one bathroom is terrible.”
Discovering Clogged Elbows
During the teardown phase, the renovators discovered multiple fittings and elbows that were nearly plugged. In some sections, only a tiny opening remained for water to pass through. This clogged interior drastically slows water flow—and also releases flakes of rust that can stain fixtures or collect in showerheads.
Why Professionals Replace Galvanized
-
Consistent Water Pressure: Newer materials like PEX or copper maintain more consistent flow rates and don’t suffer from the same internal corrosion.
-
Reduced Maintenance: Galvanized pipes often lead to frequent calls to remove blockages or fix leaks. Modern pipe materials have far fewer hidden surprises over time.
-
Cleaner Water: Rust from old pipes can make water appear discolored and taste metallic, which is far from ideal.
Switching to PEX: Pros and Cons
The renovators decided to replace the existing galvanized lines with PEX (cross-linked polyethylene). PEX is flexible, relatively affordable, and quicker to install than many rigid materials. They ran both hot and cold lines using different approaches—some with expansion fittings and some with crimp rings.
Expansion Fittings vs. Crimp Rings
-
Expansion Fittings
-
How They Work: An expansion tool temporarily stretches the PEX and a separate plastic ring wide enough to insert the fitting. The PEX then contracts back down, creating a secure seal.
-
Pros: Less risk of uneven crimping, and many pros argue it can form a tighter long-term connection.
-
Cons: Requires a specialized expansion tool, which may be more costly if you’re a one-time DIYer.
-
-
Crimp Rings
-
How They Work: A copper or stainless ring is placed around the PEX and then crimped with a manual or hydraulic tool to secure it onto the fitting.
-
Pros: Tools are often cheaper and widely available.
-
Cons: If you don’t crimp it uniformly, you risk future leaks or a ring that doesn’t hold.
-
Knowing When to Use Which
Many professionals mix and match. Some rely on expansion fittings for the main lines but keep a crimp tool handy for tricky spots or minor repairs. The key is consistency—whichever method you choose, make sure you’re doing it correctly.
Running Hot Water More Efficiently
One area the renovators wanted to address was how long it took for hot water to reach the old shower. With the water heater located across the house, the shower would sometimes run cold for upward of 10 minutes. By replacing the old lines with new PEX and eliminating super-long, corroded routes, the household will almost certainly experience faster hot water delivery.
The Plumbing “Dead Legs”
When you have lengthy horizontal runs or complicated layouts for hot water, every extra foot of pipe is water that has to flush out before fresh hot water arrives. Modernizing your layout, and even adding in a circulation line if needed, can make a huge difference.
Tip:
-
Consider a Recirculation Pump: If your water heater is particularly far from the fixture, a small pump can keep hot water circulating, significantly cutting down wait time and water waste.
Handling Overflow Jobs and the “One Part Short” Phenomenon
Anyone who has done a DIY project, plumbing or otherwise, knows that moment: you’re nearly done, only to discover you’re “one part short.” In the story here, the renovator found himself missing a shut-off valve for a kitchen sink line. A quick trip to the store turned into a $273 excursion when he realized he needed additional supplies, including more valves and fittings.
Why Plumbers Build in Parts Costs
Professionals often quote a flat price that may seem high. But keep in mind, that price often accounts for job materials (with extra supplies as a contingency). The plumber arrives with everything needed to handle small surprises without multiple store runs. This is not only more efficient but can be cheaper for the customer in the long run, since you aren’t paying for repeated trips and lost time.
How to Plan Better as a DIYer
-
Make a Detailed List: Draw a schematic of your plumbing layout and note every T, elbow, shut-off valve, coupling, transition, and faucet connector you’ll need.
-
Over-Buy and Return: Purchase a bit more than you think you’ll require. Most hardware stores allow returns for unused items, saving you emergency trips.
Mounting a New “Transformer” Setup
The DIY renovator referred to a piece of custom plumbing as a “Transformer.” Essentially, it was a set of pipes and fittings that would merge or split water supply lines in the basement, allowing him to isolate different parts of the house or outbuildings. While the final arrangement looked neat, the real test is ensuring no leaks occur under pressure and that each valve is logically placed for quick shut-off.
Why Strategic Valve Placement Matters
When installed properly, valves can isolate each branch of your plumbing system. That means you can cut off water to a single bathroom or laundry area without shutting down the supply to your entire house. It’s one of the key principles professional plumbers follow to make future repairs quicker and easier.
Checking the Water Heater
A significant observation in this remodel was an older water heater. By the date code, it might have been around two decades old, well beyond the typical lifespan of 6–12 years for a standard unit. While it was still functioning, the question is for how much longer. Additionally, the temperature and pressure relief (T&P) valve appeared to vent directly at the top without any discharge piping, a situation that can pose a burn hazard if it ever opens unexpectedly.
Safety Considerations for T&P Valves
-
Run the Discharge Pipe: A safe system has the discharge line directed down toward the floor or through a wall drain, so scalding hot water or steam doesn’t spray near anyone.
-
Age Matters: Even if your water heater still produces hot water, internal corrosion and sediment buildup can weaken the tank, affecting efficiency and risking leaks.
The Dollar Math: Surprising Costs
Initially, the renovator wanted to do the job at about half the cost of a bid near $113,000. He believed he and his friends could finish the space for around $6,500. While large projects often allow for some sweat equity savings, hidden costs—extra parts, new tools, better plumbing fixtures—can add up fast.
Typical Expenses You May Not Expect
-
Tools and Specialized Equipment: PEX expansion tools, crimpers, pipe cutters, or even a meter key if you’re shutting off water at the street.
-
Extra Fittings: Mistakes, mis-measurements, or deciding last-minute to add shut-off valves for convenience.
-
Time Delays: Even if labor is “free” because you’re doing it yourself, delays can force you to keep living in a partially finished space or hire a pro anyway when you get stuck.
Demo vs. Precision
One of the big highlights was ripping out the old galvanized lines. It’s fun to watch someone excitedly demolish a truly clogged or rusted-out section of pipe—and it’s a moment of victory to see new lines neatly installed. However, keep in mind that demolition can reveal bigger issues in older homes, such as rotted joists, mold, or hidden code violations. This is where professional experience pays off: a plumber (or general contractor) with a trained eye can often anticipate these problems before the walls come down.
The Joys of DIY and Knowing Your Limits
Despite some comedic setbacks—like discovering multiple hidden leaks or realizing the store run for “just one extra valve” ballooned into a full cart—the renovator maintained a can-do attitude. He exemplifies why many people love home improvement: it’s empowering, cost-saving, and teaches invaluable hands-on skills. That said, it’s crucial for DIYers to know where their comfort zone ends and when to call a certified plumber or electrician for complex tasks.
Signs You Should Call a Pro
-
Sewer Line Overhauls: Dealing with the main drain can become a health hazard if handled improperly.
-
Major Re-pipe with Code Requirements: If local building codes require permits, a professional is often needed to ensure passing inspection.
-
New Gas or Electric Water Heater: Incorrectly installing these can pose serious safety risks.
Conclusion
Undertaking a large re-piping and bathroom remodel with minimal experience is equal parts brave and risky. It shows the power of research, planning, and the willingness to learn on the job. Throughout this project, the non-plumber faced multiple challenges: from conquering ancient galvanized pipes to meticulously running new PEX lines and attaching them to an older water heater. Each step was a lesson in how real plumbing differs from quick assumptions. Every piece of old pipe that came out told a story about why modern materials and proper planning matter.
For the average homeowner, this remodel underscores the importance of understanding what lurks behind walls and beneath floors. Hot water inefficiencies, corroded fittings, and long supply lines can waste resources and money. Meanwhile, choosing the right valves, placing them in the right spots, and using reliable materials can ensure your plumbing remains trouble-free for years to come.
Still, success in such ambitious DIY endeavors relies on thorough preparation, realistic budgeting, and the humility to ask for help when facing something too complex or potentially dangerous. If you’re considering a similar approach—remodeling a space, swapping out plumbing, or addressing major water pressure issues—take inspiration from the positivity and perseverance on display. Just be sure to account for unexpected costs, keep safety in mind, and never be afraid to consult or hire a professional when things move beyond your comfort zone. That way, you’ll end up with a sound system and maybe even a brand-new bathroom that lasts for decades.
