If you’ve got a deep well on your property—whether it’s for a farm, a remote cabin, or a small residential development—you’ve probably spent hours weighing the cost of DIY vs. hiring someone to install the deep well pump. As a deep well pump supplier who’s been in this game for 12 years, I’ve seen it all: homeowners cutting corners to save a few bucks, only to end up with a broken pump, flooded pit, or a water supply that quits mid-summer. I’ve also seen folks overpay for “professional” help when they could have done a small part of the work to cut costs, no problem. Let’s break this down, no sales fluff, just real talk about when you need to call in a pro, and when (maybe) you can roll up your sleeves. Deep Well Pump
First, let’s get clear on what a deep well pump actually does. Unlike shallow well pumps that sit above ground, deep well pumps are submerged 20 feet or more down into your well casing, pushing water all the way up to your home or storage tank. It’s a precise system: it’s got a motor, impellers, check valves, wiring that runs hundreds of feet underground, and a control panel that regulates pressure. Skip a step here, and you’re not just dealing with minor leaks—you could damage your well casing, contaminate your water supply, or have to replace a $1,500 pump a year early. That’s not a “DIY mistake” — that’s a costly lesson I’ve heard too many customers share.
Let’s start with the cases where you almost definitely need to hire a professional. First, if you’re dealing with a well that’s newer than 10 years old, or if you don’t have any recent records of its depth and casing integrity. I can’t tell you how many times a customer has ordered a 100-foot pump, only to find their well is actually 120 feet deep, and their casing is corroded. Trying to fish a pump down a well without knowing its exact specs? You could get the pump stuck, and pulling it out is a nightmare—most well drillers charge $300 just to retrieve a stuck pump. A pro will have the right tools to measure well depth, inspect the casing for cracks or damage, and make sure the pump is sized correctly for your well’s yield (how much water it can produce per minute). Size is critical, too: if you get a pump that’s too small, your water pressure will be weak, and it’ll cycle on and off nonstop, burning out the motor. Too big, and it’ll waste energy and can damage your well over time. That’s not something you want to guess at.
Second, if you’re not comfortable working with high-voltage electricity, or if your well’s wiring is old. Deep well pumps run on 230-volt power, which is way more than the 120 volts for your outlets. Running that wire 100+ feet underground, making watertight connections, and installing the control panel safely? That’s not a job for someone who’s only wired a new light fixture. I’ve seen customers try to splice the wire themselves, only to have a short that fries the pump motor the second they flip the breaker. Not only is that dangerous—electrocution is a real risk here—but you’re out the cost of a new motor and the time it takes to get your water working again. Pros are trained to handle this kind of electrical work, and most have the proper permits required by local building codes, which can save you headaches if you ever need to sell your home down the line.
Third, if your well is more than 150 feet deep, or if it’s a large-capacity system for a farm or commercial property. I’ve installed pumps in wells over 500 feet deep, and that’s a whole different level of work. You need specialized hoisting equipment to lower the pump gently down the casing so you don’t damage the impellers, and you have to make sure the drop pipe is secured properly—if it’s not, it can vibrate and wear out, or even slip down the well. For large systems that supply irrigation or multiple homes, you also have to calibrate the pressure tank and switch to make sure they handle the high volume of water. Trying to do that alone? It’s like trying to change a tire on a semi with a regular lug wrench. You can do it, but you’re way more likely to mess something up.
Now, before you think I’m just here to push my products and tell you to hire a pro for every job, let’s talk about the times DIY is not just possible, but smart. If your well is shallow (under 50 feet deep), you have basic plumbing and electrical experience, and you’ve got clear, recent records of your well’s depth, then installing a deep well pump can be manageable. I’ve had customers who are handy homeowners with a background in plumbing install their own pumps for smaller residential wells, saving $800 to $1,200 on labor. The key here is to follow every step exactly, no cutting corners.
What do those steps look like for DIY? First, measure your well’s depth twice—use a weight on a string, not just old records, just to be sure. Order the right pump size, and make sure it’s a model that comes with clear, written instructions (a lot of budget pumps skip this, so stick to reputable brands). When you’re running the wire, make sure it’s rated for underground use, and use a waterproof connector every single time you make a splice. Don’t skimp on Teflon tape for the drop pipe connections, either—leaks here mean you’re losing pressure before the water even gets to your home. And always turn off the power to the well before you start working—no exceptions.
Even if you do DIY, though, there’s one thing I always recommend: have a pro come out and inspect your work before you flip the breaker. A quick check will make sure the connections are safe, the pump is primed correctly, and there are no obvious leaks. It’s a $150 service call, which is way cheaper than replacing a pump that’s damaged from a faulty installation.
Let’s also talk about the long-term cost of hiring vs. DIY. The average labor cost to install a deep well pump is between $1,000 and $2,500, depending on depth. The average DIY job will save you that, but only if you do it right. A bad DIY installation can cost you $2,000 to $4,000 in repairs, plus the cost of a new pump, not to mention the time you’re without water. I had a customer last year who tried to install his own pump, skipped the check valve, and ended up with his well full of muddy water that cost $500 to have professionally sanitized. That’s money he could have saved just by paying a pro $50 to come look at his setup.
Another thing to consider: local regulations. Some areas require that well pump installations are done by licensed professionals, especially for wells that supply drinking water. That’s not a rule someone made up to be annoying—improper installation can contaminate your well with bacteria or chemicals, making your water unsafe to drink. A licensed pro will know the local rules, and will usually provide a warranty on their work, which you won’t get with a DIY job. If something goes wrong with a pro’s installation, they come fix it for free. If you mess up a DIY job, you’re on your own.
Wait, but what if I’m on a tight budget, and I can’t afford a pro? I hear that all the time, and I get it. For small, shallow residential wells, there are ways to cut costs without doing the whole job yourself. Maybe you can buy the pump, drop pipe, and wire yourself (as a supplier, I offer bulk pricing for that, no markup), and then pay a pro just to do the electrical hookup and pressure tank calibration. That usually runs $300 to $500, which is half the cost of a full installation, and you’re still getting the parts right, plus a pro to handle the tricky, dangerous parts. It’s a middle ground that works for a lot of people.
Let me wrap this up with a quick recap, so you don’t have to re-read every word. You should definitely hire a professional if: you don’t know your well’s depth or casing condition, you’re not comfortable working with high-voltage electricity, your well is over 150 feet deep, you need to comply with local regulations, or you want a warranty on the installation. You can try DIY only if: your well is under 50 feet deep, you have basic plumbing and electrical skills, you have accurate well records, and you’re willing to pay a pro to inspect your work at the end. No matter what, never skip the safety steps—water is essential, and messing up your well pump can leave you without it for days, or even contaminate your water for months.
At the end of the day, this is about more than just installing a pump—it’s about having reliable, safe water for your home or property. For 12 years, I’ve supplied deep well pumps to homeowners, farmers, and contractors, and my number one rule is always: be honest with yourself about your skills. If you’re even a little unsure, call a pro. If you’re confident, do your research, follow the instructions, and stay safe.

Before you go, a quick note on choosing a supplier: not all pumps are the same, and buying a cheap, off-brand pump might save you a few bucks now, but it’ll die in 2 or 3 years, vs. a reputable pump that lasts 8 to 10 years. That’s why I always recommend going with a trusted brand, and working with a supplier who knows deep well systems, not just sells parts. We’ve tested every pump we carry, and we offer support long after the sale is done.
