Stop Dry Running Before It Destroys Your Pump
Dry running is the #1 cause of premature well pump failure in Southern Maryland. A Pump Saver monitors your pump's amp draw and shuts it off the moment it runs dry — protecting a contact us for a free estimate investment for a fraction of the cost.

What Is a Pump Saver?
A Pump Saver is an electronic protection device installed on the pump circuit between the control box and the pump. It continuously monitors the pump's current draw and voltage — the electrical signature of a healthy, water-moving pump.
When the pump runs without water (dry-run), the current drops below normal because the pump is no longer working against water resistance. The Pump Saver detects this drop within seconds and shuts the pump off before the motor overheats and burns out.
Beyond dry-run protection, Pump Savers also detect under-voltage, over-voltage, and phase loss (on 3-phase systems) — all conditions that can destroy a pump motor. After a configurable delay, the device attempts an automatic restart. If the well has recovered, the pump runs normally. If not, it shuts off again and waits.
Common brands we install: Franklin Electric SubDrive, Pumptec, and SureSeal.
What a Pump Saver Protects Against
Five threats that destroy well pumps — and how a Pump Saver stops each one.
Dry-Run Damage
A pump running without water overheats within 15–30 minutes. Motor burnout is the result — and it is not covered under most pump warranties. A Pump Saver detects the drop in current draw and shuts off the pump before damage occurs.
Under-Voltage
Low voltage causes the motor to draw excess current to maintain speed. The excess current generates heat, degrading motor insulation and shortening pump life. A Pump Saver detects under-voltage and shuts down before damage accumulates.
Over-Voltage
High voltage stresses motor windings and can cause insulation breakdown. Surge events from lightning or utility switching are common causes. A Pump Saver with surge protection detects and responds to over-voltage conditions.
Phase Loss (3-Phase Systems)
Single-phase operation of a 3-phase motor causes immediate overheating and rapid motor destruction — often within minutes. A Pump Saver detects phase loss and shuts down before the motor is destroyed.
Rapid Cycling
Some Pump Saver models detect and prevent rapid cycling — the repeated start/stop that occurs when a pressure tank is waterlogged. Rapid cycling stresses motor windings and shortens pump life significantly.

Recent Job — Prince Frederick, MD
After replacing a well pump in Prince Frederick that had burned out from dry running, we installed a Pump Saver on the new pump. The homeowner had already replaced that pump twice in 5 years — both times due to dry running during summer droughts when the water table dropped.
We installed a Franklin Electric Pump Saver wired into the pump's control circuit. The following summer, the Pump Saver activated three times during a dry stretch — shutting off the pump, waiting for the well to recover, and restarting automatically. The homeowner noticed the water pressure cycling but the pump survived.
That pump is still running two years later. Without the Pump Saver, it would almost certainly have been a third replacement.
Pump Saver FAQs
What is a Pump Saver and how does it work?
A Pump Saver monitors the pump's electrical current. When the pump runs without water (dry-run), current drops below normal. The Pump Saver detects this and shuts the pump off before damage occurs. It also detects under-voltage, over-voltage, and phase loss.
Do I need a Pump Saver if I have a Cycle Stop Valve?
They serve different purposes. A CSV prevents rapid cycling and manages low-yield wells. A Pump Saver protects against dry-run damage and electrical issues. For low-yield wells, both are recommended.
Will a Pump Saver prevent all pump failures?
No — it protects against dry-run damage and electrical issues. It does not prevent mechanical wear, bearing failure, or impeller damage from sediment. It is one layer of protection, not a complete solution.
How do I know if my pump has run dry?
Signs include sudden loss of water pressure, air sputtering from faucets, and the pump cycling rapidly then shutting off. A Pump Saver with a fault indicator will show a dry-run fault code.
Can a Pump Saver be installed on any well pump?
Most single-phase submersible pumps are compatible. We verify compatibility before installation. Three-phase pumps require a 3-phase Pump Saver model.
Does a Pump Saver require maintenance?
Minimal — we check it during annual well maintenance visits. The device itself is solid-state with no moving parts and typically lasts 10–15 years.
What happens after a Pump Saver shuts the pump off?
Most models wait a configurable delay (15–60 minutes) then attempt to restart. If the well has recovered, the pump runs normally. If not, it shuts off again and waits for another restart attempt.
Can a Pump Saver be installed on a 3-phase pump?
Yes, and it is especially important for 3-phase pumps — phase loss destroys 3-phase motors very quickly. We install 3-phase Pump Saver models for commercial and agricultural well pumps.
How long does Pump Saver installation take?
1–2 hours for most installations. We schedule a half-day appointment to allow time for testing and documentation.
Is a Pump Saver worth it for a new pump?
Absolutely — a new pump is a contact us for a free estimate investment. A contact us for a free estimate Pump Saver protects that investment for the life of the pump. We recommend installing a Pump Saver with every new pump installation.
What is a Pump Saver and what does it protect against?
A Pump Saver is an electronic protection device installed on the well pump circuit that monitors motor current and voltage. It protects against: dry running (pump running without water, which destroys the motor in minutes); voltage fluctuations and surges; single-phasing (loss of one phase on 3-phase systems); overload conditions; and rapid cycling. When a fault condition is detected, the Pump Saver shuts off the pump and prevents damage.
How does a Pump Saver detect dry running?
A Pump Saver monitors the motor's current draw. When a pump runs dry (no water to pump), the motor draws less current than normal because it has no load. The Pump Saver detects this current drop and shuts off the pump within seconds — before the motor overheats and burns out. This is the most valuable protection feature for wells with low yield or seasonal water table fluctuations.
What brands of Pump Saver do you install?
We install Franklin Electric SubMonitor, Pumptec, and SureSeal Pump Saver devices. We recommend the device based on your pump size, motor type, and the specific protection needs of your well system. We stock these devices and can typically install same-day or next-day.
How much does Pump Saver installation cost?
Pump Saver installation cost depends on the device model and the complexity of the electrical installation. It is a fraction of the cost of a pump replacement — making it one of the best investments a well owner can make. We provide a written estimate before installation.
Does my well pump need a Pump Saver?
A Pump Saver is most valuable for: wells with low yield or seasonal water table fluctuations; older pumps approaching end of life; homes in areas with frequent power fluctuations or lightning; and any well where a pump failure would cause significant hardship. If your well has had pump failures in the past, a Pump Saver is strongly recommended to protect the new pump.
Can a Pump Saver be added to an existing well system?
Yes — a Pump Saver is installed at the control box or pressure switch location and does not require pulling the pump or any work inside the well. Installation is typically completed in 1–2 hours. It is compatible with most standard single-phase submersible pump systems.
Will a Pump Saver prevent all pump failures?
A Pump Saver prevents the most common causes of premature pump failure: dry running, voltage problems, and overload. It does not prevent mechanical wear, bearing failure, or physical damage from sand or debris. However, by preventing the most damaging failure modes, it significantly extends pump life and reduces the likelihood of emergency pump replacement.
What happens when a Pump Saver trips?
When a Pump Saver detects a fault condition, it shuts off the pump and typically enters a lockout or time-delay mode. Some devices have an LED indicator that shows the fault type. After the fault condition clears (well recovers, voltage stabilizes), the device may automatically restart the pump after a time delay, or require a manual reset. We explain the device operation during installation.
Is a Pump Saver the same as a surge protector?
A Pump Saver includes surge protection but does much more — it also monitors for dry running, overload, and voltage problems. A standard surge protector only protects against voltage spikes. For well pumps, a Pump Saver provides more comprehensive protection than a surge protector alone.
Does a Pump Saver void my pump warranty?
No — installing a Pump Saver does not void pump manufacturer warranties. In fact, some pump manufacturers recommend or require protection devices. We install Pump Savers in a way that is compatible with all major pump manufacturer warranties.
How long does a Pump Saver last?
Pump Saver devices are solid-state electronics with no moving parts and typically last 10–15 years or longer. They require no maintenance. We recommend testing the device annually as part of your well system maintenance to confirm it is functioning correctly.

"We recently had Deep Dive Plumbing Maryland out to our home in Annapolis after we suddenly started noticing sewer flies throughout the house. They truly lived up to their name and performed a full "deep dive" diagnostic inspection instead of just treating the symptom. During their inspection they discovered our sewer pipe connected to the toilet had been leaking into the basement for quite some time. The team explained everything clearly, provided upfront pricing before starting any work, and even gave us a military discount which was greatly appreciated. They were professional, respectful, extremely knowledgeable, and took the time to make sure the repair was done correctly."

"Absolutely blown away by the service from Deep Dive Plumbing Maryland! We had ongoing issues with our well water for years — bad smell, staining, and constant problems with pressure — and nobody ever took the time to truly figure out the root cause. Terry and the team came out, performed a full water analysis, explained everything in detail, and designed a system specifically for our home instead of just trying to sell us random equipment. You can really tell they care about doing things the right way. The install was extremely clean and professional, they walked us through how everything works, and our water has never looked or tasted better. The difference is unbelievable."
