Confused whether you should call a licensed plumber or do it yourself? Join us as we discuss the pros and cons of DIY plumbing and when you should call a professional.
The internet is brimming with resources, especially video guides on YouTube, making it quite tempting to tackle most plumbing issues yourself with a DIY approach.
You can tackle many jobs yourself, like fixing taps, dealing with pipe leaks, installing sinks, or unclogging toilets, saving you money on professional services. But when tasks become too complex, it’s wise to call in a master plumber who can swiftly identify and resolve the issue.
Don’t know when you should call a professional? For better understanding, we will walk you through DIY plumbing and projects that may be more appropriate for licensed plumbers.
DIY Vs. Professional Plumbing
Before considering either plumbing option, it’s best to weigh their pros and cons and see which suits your situation better.
Pros of DIY Plumbing
1. A Great Learning Opportunity
Learning home improvement techniques like plumbing requires hands-on experience rather than reading self-help guides. You must apply what you learn, so fixing some minor plumbing issues immediately after watching a tutorial or reading a guide is helpful. Knowing simple repair methods can be immensely useful when a professional plumber is unavailable.
2. Cost Saving
Saving money on plumbing expenses is why homeowners choose to DIY instead of hiring a professional. But, if you’re worried about the additional costs, you can buy the tools and mechanical parts needed from local hardware stores before the professional arrives.
If your home has a severe plumbing emergency, saving money shouldn’t stop you from getting professional help. Getting the issue appropriately fixed can save you money in the long run.
3. Makes You Self-Sufficient
Undoubtedly, successfully performing a plumbing project or installation boosts your self-confidence. This way, you’ll become more self-reliant for plumbing issues in the future.
Cons of DIY Plumbing
1. Inaccurate Diagnosis
Regarding DIY plumbing, you may misdiagnose the plumbing issue since you have limited knowledge about repair and installation. Using the wrong fix for a specific problem may aggravate the situation and cause damage to the plumbing system.
2. Riskier
Since you’re not as experienced as a professional, you might be unaware of the safety hazards or potential risks while working on different plumbing components. Plumbing jobs require several chemical solutions that can harm your health if you inhale or ingest them.
3. No Licence
You would require a licence to do specific plumbing jobs, such as renovation, fixing broken pipes, exterior plumbing, etc.
Pros of Professional Plumbing
1. Accurate Diagnosis
Professional plumbers can quickly identify what’s wrong with a plumbing component since they have the proper skill set and experience. This way, you’ll get the right solution to your plumbing difficulties.
2. Better Quality of Work
Hiring professional plumbers usually ensures quality repairs or installations that last. In contrast, DIY attempts might not always offer long-lasting solutions.
3. More Safety
Since licensed plumbers are more experienced, they know how to handle toxic chemicals and solutions by keeping themselves out of harm’s way. They can also identify polybutylene piping and mould growth and quickly resolve them for your safety.
Cons of Professional Plumbing
1. Labour Charges
Professional services are charged based on labour and additional charges (which include tools and extra parts required). So, unlike DIY plumbing, you’ll also have to pay for labour.
Plumbing Works That Require Professional Assistance
1. Exterior Plumbing
For several reasons, exterior plumbing features such as inbound and outbound pipes may require repair or maintenance. These pipes tend to wear out faster since they come in close contact with dirt, strong tree roots, flooding, etc. Proper inspection and identification of the problem in these exterior plumbing parts are complex and are best done by professionals.
2. Interior Plumbing
Indoor plumbing components, often hidden in walls, floors, and ceilings, can be challenging without hands-on experience. These tasks might demand extra manpower, necessitating professional assistance. With concealed plumbing lines, pinpointing issues demands thorough inspection and significant plumbing expertise.
3. Fixing Frozen or Broken Pipes
If your pipes are broken or frozen, it’s time to call a professional plumber. They’ll help you understand the cause of the breakage, and in the case of frozen pipes, they will carefully thaw them to avoid fractures and water damage.
4. Renovation
Major renovation projects such as bathroom or kitchen remodelling are labour-intensive and require professional assistance. Plus, these projects require proper knowledge of building codes and suitable permits.
Plumbing Works That You Can DIY
1. Repairing Or Replacing Toilet Parts
Simple repair or replacement of faulty parts, such as chains, shutoff valves, fill chains, seals, broken faucets, etc., can be done at home using DIY kits from hardware stores. However, serious plumbing issues such as water or line leaks might require careful inspection and fast repair.
2. Clogged Drains Or Slow Drainage
Unclogging toilet and shower drains is pretty standard - the procedures are simple, and you’ll find the required tools in local hardware stores. If required, you only need drain cleaners (baking soda is a safer, non-toxic option), a plunger, a wire hanger, and a drain cover.
You can also buy a drain filter for the shower to trap hair and dirt. This way, you can prevent clogged drains in the future.
3. Installing New Taps
Putting new taps in place is also relatively easy - turn off the valves, remove the old tap, and replace it with the new one. However, if you damage the valves or cannot find the proper alignment for the new tap, you should call a professional.
4. Leaky Faucet
Although repairing a leaky faucet can become more technical, you can quickly fix it by following a guide or tutorial. Before starting the repair, we recommend familiarising yourself with the different parts included in a faucet.
DIY or Professional Plumbing
You’ve likely noticed that handling simple tasks like fixing faucets or clearing clogged drains can be straightforward. However, some plumbing problems definitely require professional expertise due to their complexity or potential hazards.
However, if you’re still unsure about minor plumbing jobs, we suggest hiring a professional to be on the safe side.
