Jabsco 18670-0000 12V Dry Tank Switch
The Jabsco 18670-0000 is the Jabsco 12 volt dry tank switch, an automatic shut off for flexible impeller pumps. It stops the pump when the tank or supply runs dry, protecting the impeller from dry running damage when the pump is left to empty a tank on its own.
These bronze flexible impeller pumps self-prime, handle small debris and can be mounted in any position, which is why they are used for bilge, washdown, livewell and transfer duty. Keep suction lines airtight so the pump can prime, drain it before freezing weather, and never let it run dry because the impeller depends on the liquid for lubrication.

Frequently Asked Questions
Q: Can it be mounted in any position?
Yes, although mounting with the pump head below the motor keeps any seal leakage away from the motor.
Q: Why will it not self-prime?
Almost always an air leak on the suction side. All suction connections must be airtight.
Q: How long can it run dry?
Only seconds. The impeller relies on the liquid for lubrication.
Q: What do I do before freezing weather?
Drain the pump by loosening the end cover so trapped water cannot freeze and crack the body.
