Pump Saver Protection Systems
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 $2,000+ investment for a fraction of the cost. Installed by Deep Dive Plumbing Maryland, Licensed Master Plumber #98433.
The Math Is Simple
Without a Pump Saver
$1,500–$3,500
Emergency well pump replacement — parts, labor, and the disruption of having no water.
With a Pump Saver
$200–$400
Pump Saver installation — protects your pump for its full 10–15 year lifespan.
A Pump Saver pays for itself the first time it prevents a dry-run failure. For homeowners who have already replaced a pump due to dry running, it's not optional — it's essential.
Who Needs a Pump Saver?
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?
A Pump Saver (also called a pump protection relay or dry-run protection device) is an electronic device that monitors the electrical current draw of a well pump motor. When a pump runs dry — meaning it's pumping air instead of water — the motor draws less current than normal. The Pump Saver detects this drop in current and shuts off the pump before the motor overheats and burns out. After a set delay (typically 10–30 minutes), it automatically restarts the pump to check if water has recovered.
Why is dry running so dangerous for a well pump?
Submersible well pumps are cooled by the water flowing through them. When the pump runs dry, there is no water to cool the motor — it overheats rapidly. Even a few minutes of dry running can destroy a pump motor that might otherwise last 15 years. Dry running is the single most common cause of premature well pump failure, and it's entirely preventable with a Pump Saver.
How does a Pump Saver work?
The Pump Saver is wired in series with the pump's power supply. It continuously monitors the pump's amp draw. When the pump is running normally — pumping water — the amp draw is within a normal range. When the pump runs dry, the amp draw drops below the normal range (less load on the motor). The Pump Saver detects this and cuts power to the pump within seconds. It then waits for the programmed restart delay before attempting to restart the pump.
Does every well need a Pump Saver?
We recommend a Pump Saver for any well that has had a pump replaced due to dry running, any low yield well, any well in an area with seasonal water table fluctuations, and any well where the pump is positioned near the bottom of the water column. For wells with consistently high water levels and no history of dry running, a Pump Saver is still a good investment — it's inexpensive insurance against a very expensive repair.
How much does a Pump Saver cost compared to pump replacement?
A Pump Saver installation typically costs $200–$400 including parts and labor. A well pump replacement in Southern Maryland typically costs $1,500–$3,500 depending on well depth and pump size. The Pump Saver pays for itself the first time it prevents a dry-run failure. For homeowners who have already replaced their pump once due to dry running, a Pump Saver is essential.
Can a Pump Saver be added to an existing pump?
Yes — a Pump Saver can be added to virtually any existing submersible pump installation. It is wired into the pump's control circuit at the pressure switch or control box. Installation typically takes 1–2 hours and does not require pulling the pump from the well.
What brands of Pump Savers do you install?
We install Franklin Electric Pump Saver, Pumptec, and Grundfos pump protection devices. We select the appropriate device based on your pump's horsepower and electrical specifications. All devices we install are backed by our 18-month parts and labor warranty.
Will a Pump Saver work with a constant pressure system?
Most constant pressure VFD controllers have built-in dry-run protection that functions similarly to a Pump Saver. If your constant pressure system has this feature enabled, a separate Pump Saver may not be necessary. We evaluate each system individually and recommend the appropriate protection.
What happens when the Pump Saver shuts off the pump?
When the Pump Saver shuts off the pump, it waits for the programmed restart delay (typically 10–30 minutes) to allow the well to recover. Then it automatically restarts the pump. If the pump runs dry again, it shuts off again and repeats the cycle. This continues until the well has recovered enough water to run the pump normally. You may notice reduced water pressure or intermittent water during this recovery period.
Does a Pump Saver protect against voltage spikes and lightning?
Some Pump Saver models include surge protection that guards against voltage spikes and lightning damage. Lightning is a significant cause of pump motor failure in Southern Maryland. We recommend adding a dedicated surge protector to the pump circuit in addition to the Pump Saver for maximum protection.
