SOURCE: I have a Pentair Intelliflo pump system and lately

Your pipe could be clogged or you may have a clog in the impeller. Check the pump basket and if it is cracked then it is probally in the impeller and you may be able to reach it with a screwdriver and needlenose. If you have a crack in the skimmer basket it could be in the line and you can check this by putting a kitchen sponge in the skimmer and if it comes out in the pump the line is clear. If it is clogged you may be able to clear it with a flush bag you can get at any hardware store. If that dosn't do it you will need to get a pro. Good luck.

How do I manually reset my Intelliflo pump? The priming alarm came on after I tried to vacuum pool. Now it wont work.

turn off breaker to pump for a few minutes, then back on this will reset your alarm. If the problem returns ,check other posted solutions. In a few weeks i may have location of someone who repairs circuitboards for pentair pumps, as i am having one repaired now due to lightning hit.

The pump keeps trying to prime. There is no air in the lines. all the valves are open. filter basket is clean. we've tried hitting the reset button, changing the prime time from 1min. to 5 min....

Most of the time you are sawing air from thpumo lid. Hav you lubricated the o-ring in the lid? If that doesn't work, keep working your way forward and lubricate the 3 way valves as well.

I have intelliflo VS+SVRS pool pump, after stopping for 4 days i want to start again & after start it goes to priming & then alarm & it says clear the drain & restart

There is either something blocking the suction side of this pump (blocked valve, strainer, strainer basket, leaves on main drain.) or the pump is not getting primed in the aloted amount of time. You can increase the priming time on the pump, or manually prime it, or just turn off the svrs feature temporarily until you get a good prime again. If you need the manual to figure out how to do these things, here is the link.

3/4 Whisperflo will not prime

once you figure out why it's having trouble priming, you can reduce the discharge side with a valve to adjust the flow to what you need. You can always always reduce the discharge side but never the suction side.

Intelliflo SVRS Pump not able to ramp up without help

These pumps are very sensitive. If you are pushing the on button and the pump trys to prime and then the alarm kicks on I would check the following:

Water level in pool
Make sure skimmer weir door are not stuck in up position

Most Likely Cause
Diffuser oring needs to be replaced on pump. Easy check - shut power off to pump: remove 6 bolts that hold seal plate together (2 on top and 2 on bottom of each side of seal plate with no nuts, and 2 in middle on each side of seal plate with nuts) do not remove bolts that mount motor to pump. Once 6 bolts are removed, grab motor and pull motor unit away from pump. You will see a cone at the end of the assembly with an oring on it. Make sure the oring is snug, if not replace. This is most likely what is causing your problem.
