Quick question hopefully.

I replaced my motor in Dec of 2020 and I've notice corrosion building up. See picture.

I do live on the coast and there are time I've had pool water splash up on the pump. I have a SWG. Is this normal of a sign of a leak or another problem.

Thank you in advance.

A thin film on the surface is normal. Deeper corrosion or pitted I would be alerted to something else going on. A visual check of your wiring and bonding cable might be in order.
 
Probably a seal leak.

Look under the pump with a flashlight to see if it is dripping.

There's a gap under the seal plate that makes it easy to see a drip if you have good light and the right angle.

Be careful around a working motor and wear eye protection.

Ok, I don't see a drip.

Keep checking periodically.

You had corrosion before, so maybe it's a seal leak or maybe some sort of stray current.

Is the motor properly bonded?

Disconnect the bond wire from the motor and check to see if there is a measurable amount of voltage between the motor bond lug and the bond wire.

Pump question

I have a Hayward super pump. It’s about 3 years old. We purchased the house last year. We have been having problems with the gfci tripping and the electrician tested everything and said there must be water getting into the pump somehow. Then all of a sudden the pump for very loud. Upon...

This clear spot looks like a place where water has been dripping.

Around the spot, you can see calcium carbonate from the water when the water evaporates.

I would replace the seal with a good seal.

What seal did you use last time?

I bought everything from inyopool.

I don't mind changing it out again to be safe. Is that a good choice?

The PS-1902 is actually the best seal.

The PS-1902 has a Silicon Carbide Primary Ring and a Silicon Carbide Seat.

It's more expensive, but if it can save a motor or save the cost of your time to replace the seal again, the cost difference is probably a good investment.

What is the total hp of the motor?

I would not increase the impeller.

What's wrong with the flow?
