Common Questions
What does a pitless adapter do?
A pitless adapter connects the submersible pump drop pipe to the underground water line leading to the home.
Why does my well need a pitless adapter?
It allows water to exit the well below the frost line, helping protect the water line from freezing.
Where is a pitless adapter installed?
It is installed through the well casing below the frost line.
Can a pump be pulled with a pitless adapter?
Yes. A pitless adapter installed in a 5-inch well casing or larger allows the pump and drop pipe to be pulled without digging up the female portion of the adapter.
How do I know what size pitless adapter I need?
Match the adapter to your well casing size, drop-pipe size, discharge-line size, and pump configuration.
When should I replace a pitless adapter?
Replace it if it is leaking, corroded, difficult to service, damaged, or incorrectly sized for the well system.
