One great feature of the Pentair Intelliflo Variable Speed Pump is the self-priming option. The pump is sent from the factory with this option on. However, because the pump runs at maximum power at start up, it is very loud and some people are bothered by it. If your pump is located outside a bedroom or office, you may be annoyed by the sound when the pump starts.
My pump never loses prime, so I am not concerned with the priming feature. When I clean my filter basket I may need to prime the pump again, but that is easy to accomplish by selecting one of the higher speeds manually for a moment when I first start the pump. I prefer to turn the priming feature off to avoid the noise. Here’s a video that shows you how to turn off (and on) the priming feature on the Pentair Intelliflo Variable Speed Pump.

With the pump off, the buttons to press to toggle priming on or off are:
Menu | Down| Down| Down| Down | Select | Select | Down | Enter
Rather than turning auto-priming off, you can also change the priming sensitivity. The pump will detect whether priming is necessary, and theoretically will not go into auto-priming mode if it detects that the pump is primed. However, I have not had good success adjusting sensitivity to reduce unwanted priming. I find it’s better to just turn off the feature.
WARNING: If you turn off the priming feature and your pump detects that it is not primed, it will go into error mode to protect the pump. This is a great feature to save your pump from damage, but it must be reset manually. I have never experienced a problem with this, but if your pump loses prime frequently, it could be a problem. Then again, if your pump loses prime frequently, you should determine the cause and fix it!
