Before you call a pro, see our review of the 6 best well pump repair kits. These DIY kits can fix common issues and save you a costly service call.

It always seems to happen during a dry spell, right when the garden is at its thirstiest. Before you reach for the phone to call a service technician and brace for the bill, know that many common pump failures can be fixed with a simple, inexpensive repair kit.

Signs Your Well Pump Needs a Repair Kit
The most obvious sign is when the pump motor runs, but you get little to no water at the spigot. You might hear it humming away in the well house, but the pressure gauge is sitting at zero. This often points to a worn-out impeller that’s just spinning in the water instead of slinging it.
Another classic symptom is weak or sputtering pressure. If your sprinklers are barely misting or the hose just dribbles, the pump is struggling to build pressure. This could be a failing gasket or a worn diffuser, preventing the pump from working efficiently. It’s losing the fight.
Pay attention to the sounds and cycles of your pump. A pump that turns on and off rapidly—called short-cycling—is under stress, but that’s often a pressure tank issue. However, if you hear new grinding or whining noises, that can signal worn internal parts. A repair kit is for a pump that is mechanically worn, not one with a dead or fried motor.
Flotec FP0034-10U: The Go-To Universal Kit
This is the kit you’re most likely to find hanging on a peg at the local big-box hardware store. The Flotec universal kit is designed to be a jack-of-all-trades for common shallow well and convertible jet pumps. It’s a lifesaver when you need water now and can’t wait for a special order part to arrive.
Inside the package, you’ll typically find the core components that wear out: an impeller, a diffuser, and an assortment of gaskets and O-rings. These are the parts responsible for actually moving water and creating pressure. Installing them can take a pump from non-functional to fully operational in an afternoon.
The tradeoff for this convenience is its universal nature. "Universal" often means it fits many things acceptably, but nothing perfectly. While it will likely get your pump running again, it may not restore it to the exact factory-specified performance or have the longevity of a manufacturer-specific kit. Think of it as a very good spare tire, not a brand-new performance wheel.
Red Lion RJS-PREM-KIT for Premium Rebuilds
When you have a solid, reliable Red Lion jet pump, you don’t want to fix it with just any parts. The RJS-PREM-KIT is a model-specific rebuild kit designed to restore these workhorse pumps to their original performance. This is the choice for a planned repair, not a frantic emergency fix.
This kit is a cut above the universal options. It often includes a high-quality thermoplastic impeller and diffuser, a carbon-ceramic mechanical seal, and all the precise O-rings and gaskets needed. The goal here isn’t just to make the pump work; it’s to make it work like new. You’re essentially replacing the entire "wet end" of the pump.
Choosing this kit is an investment in a piece of equipment you already trust. If your Red Lion pump has provided years of faithful service and the motor is still strong, a premium rebuild is far more economical than replacing the entire unit. It’s the smart, sustainable choice for getting another decade of life out of your pump.
Goulds AOKIT2: Rebuild Kit for J-Series Pumps
Goulds pumps are the standard on many farms for a reason: they are built to last. When one of their legendary J-Series pumps finally shows its age, the AOKIT2 is the official, no-compromises solution. This is not a generic kit; it’s an OEM (Original Equipment Manufacturer) package engineered for a specific job.
Using an OEM kit means every part is a perfect match. The impeller, mechanical seal, and gaskets are identical to the ones installed at the factory, ensuring you maintain the pump’s designed efficiency and flow rate. There is no guesswork and no "close enough" parts.
This precision comes at a higher price than a universal kit, but you’re not just buying parts; you’re protecting a significant investment. A properly rebuilt Goulds pump is ready for another long tour of duty. Skimping with a generic kit on a high-quality pump is like putting cheap tires on a heavy-duty farm truck—it compromises the performance of the whole system.
Myers OK75 Kit for Classic HJ Series Pumps
Walk around enough small farms and you’ll find an old, heavy, cast-iron Myers pump humming away in a corner. These things were built like tanks. The OK75 kit is specifically for these classic HJ series convertible jet pumps, providing the essential wear parts to keep them in service.
This kit focuses on the most common failure points in these older designs: the rotary seal, gaskets, and O-rings. Over decades of service, these are the components that dry out, crack, and fail. The impeller and diffuser in these pumps are often incredibly robust, but the seals are their Achilles’ heel.
Rebuilding an old Myers pump with this kit is about honoring good iron. It’s a frugal and deeply satisfying task. Instead of sending a perfectly good pump to the scrap heap because of a ten-dollar seal, you can restore it to full working order. It’s a practical nod to the days when equipment was designed to be repaired, not replaced.
Wayne 63101-WYN1: For CDU Utility Pumps
Not every pump on the farm is a well pump. We all have those little utility pumps for draining flooded stalls, transferring water from a rain barrel, or emptying a stock tank. The Wayne CDU series is one of the most common, and this kit is what keeps them from becoming landfill.
These pumps often fail due to a simple worn shaft seal or a bad O-ring, causing them to leak or lose their ability to prime. The 63101-WYN1 kit contains exactly these small, crucial parts. It’s a simple fix that most people overlook, opting to just buy a new pump.
This kit represents a shift in mindset. It turns a cheap, "disposable" tool into a serviceable one. For a few dollars and about 30 minutes of your time, you can save a $100 pump from the trash. That’s smart resource management on a small-farm scale.
Simmons 1161: The Simple Check Valve Fix
Sometimes, the pump isn’t the problem at all. If your pump runs and runs but never builds pressure, or if it loses its prime between cycles, the culprit is often a faulty check valve or foot valve at the bottom of the well pipe. This valve is supposed to hold water in the line, and when it fails, the water drains back into the well.
The Simmons 1161 kit isn’t a pump repair kit, but a check valve rebuild kit. It contains the essential guts of the valve: the rubber poppet, a gasket, and a new spring. These are the parts that wear out and allow water to leak past.
Before you pull your entire pump apart, check this first. It can save you hours of unnecessary work. Fixing a check valve is often much easier than rebuilding a pump, and this simple, inexpensive kit solves one of the most common "no water" complaints. It’s a critical piece of diagnostic knowledge for any well owner.
Choosing the Right Kit for Your Pump Model
The first and most important step is to find the model number of your pump. It’s usually on a small metal plate on the pump housing or motor. Without this number, you are just guessing. Take a picture of it with your phone so you have it handy.
With the model number, you can make an informed choice. Your decision depends on your situation:
- For an immediate, emergency fix, a universal kit like the Flotec can get you out of a bind.
- For a planned repair on a pump you rely on, an OEM-specific kit like the Goulds or Red Lion is the superior choice for long-term reliability.
- For bringing an old, trusted pump back to life, look for a dedicated kit like the Myers.
One final piece of advice: if you have the time, take the pump apart before you order the kit. Seeing the failed part with your own eyes confirms the problem and ensures you’re buying what you actually need. It’s better to wait one more day for the right part than to get the wrong one delivered and have to start all over.
A pump repair kit is more than just a collection of spare parts; it’s a tool of self-reliance. Knowing how to diagnose and fix your own well pump saves you money, but more importantly, it gives you control over your farm’s water supply. It transforms a potential crisis into a manageable weekend project.
