Can I manually prime my spa pump?

Posted by on . 2 comments.


I just drained and refilled my spa. After bleeding all the air out of the system and ensuring all the valves were open I turned on the pump. The pump turns (the motor runs) but no water is pumped (other than a single bubble when I first turn the pump on). I think the pump isn't self-priming. Can I manually prime it? Can I force water into the pump somehow?

    Some pumps have a strainer built in with the impeller housing. If it has one then simply loosen the cover and add water as necessary.

    Some systems have a check valve in the line on the suction side of the pump. This might be preventing water from getting to the pump. The pump should have a drain plug and they usually also have a plug near the top. If this is the case remove the top plug and prime the pump.

    The filter might also be keeping an air bubble and keeping water from entering the pump. If this is the case just fill the filter .

    I suspect you are talking about a pump pumping through a filter… get your hose, fill the pump and turn on, repeat until the filter picks up and pumps the water! Make sure you don’t run the pump excessively without water going through it!
