# Priming

Priming is filling the pump with water so it can start pulling.

A pump cannot move water if it is full of air. Priming means getting water into the pump housing. A pump that runs but never fills the basket has lost prime.

Common causes are a low water level, a full basket, a dry or cracked [lid O-ring](https://marinapool.multisites.ai/glossary/lid-o-ring), or an [air leak](https://marinapool.multisites.ai/glossary/air-leak) in the suction line. Turn off power, fill the basket with water, close the lid tight, and restart. Do not run a dry pump for long, since it can burn the [seal](https://marinapool.multisites.ai/glossary/shaft-seal). If it will not prime, call a pro.
