Pentair IntelliFlo Pump Corrosion

[Blancmik]

Fellow TFP'ers... need some help.

I have a Pentair IntelliFlo VSF (#011056) pump that was installed in April of 2019 and I'm seeing some pretty significant corrosion on the pump. Should I be concerned about this? If yes, is there something that I can do to prevent/control the corrosion?

You are in Florida. How close to the ocean water? Everything corrodes in Florida.

Yes, in Florida and about 15 miles inland from the coast. Anyone else in Florida seeing lots of corrosion?

Doing some additional searching on the forum, sounds like a lack of bonding may be the issue ( Link to Post )... I believe the bonding wire is what I see on the side of the pump (1st photo). Any suggestions on how to test that this is setup correctly? I don't fully understand the bonding vs grounding concept. :-(

File a warranty claim and let the pool builder or Pentair deal with it.

Something is causing accelerated corrosion. Maybe a seal leak or possibly stray current.

Disconnect the bond wire and measure the voltage from the pump bond wire lug to the bond wire.

Then reconnect the bond wire.
