Thanks PoolDoc.
I was thinking about building a little "doghouse" style roof over the pump / motor to mitigate that possibility. I have been wondering how the motor came to have so much corrosion in just 5 years of service and can only imagine that some combination of premature shaft-seal failure or leakage and possibly heavy rain / flooding of the motor vents contributed. I will keep an eye out so I (hopefully) don't have to go through this again in another 5 years!

I have a similar problem (pump motor gets regularly drenched in the rain). Mine is on a pad but we get lots of heavy rain here in FL. I was considering doing the exact same thing with the "doghouse". I was thinking it might present a problem for cooling/airflow, though. I had considered one of those solar fans for the roof of a house. The problem with that is the combined cost makes me doubt the economics of doing that vs buying a new pump every few years. Hopefully someone else can weigh in on the merits of the idea.

Great idea raising the pump up 2" or so. I will definitely do that at the end of the season since it means some plumbing modifications. Mine sits on a pad but it's only about an inch above the surrounding grade and the area is covered in that ground cloth that prevents weeds from growing up everywhere. I'm thinking since that ground cover doesn't drain very quickly, if it gets soaked, perhaps the water level in a very heavy downpour might be rising up to the level where the motor sits.
As far as the "doghouse" goes, I did say "roof." I may not know much but I do know that if the motor has vents it's going to need airflow... I wasn't planning on totally enclosing the motor but thanks for back-stopping me.
Would it be overkill to disconnect the motor and bring it inside during the winter months? Or would that just wreak havoc on all of the seals that keep the water out from between the pump and motor? I'm not looking to create more work for myself, just curious since our season is only about 4 months long here. I do remove the SWCG cell during the winter months so there's no chance of any water being left in it and having a freezing problem.
I wouldn't remove the motor. But what is possible is to re-install the pump with 2 unions, and replace the electrical to the pump with a locking cord, using something like this:Quote:

You'd need to make sure that water didn't drip all over the plug & socket set. You'd also need to solder the wire ends, especially on the motor connections. Fine stranded wire will not maintain a good connection under those terminals, with all the vibration and such.

But, with the unions and the cord set, you could simply disconnect the entire pump and store it indoors.
Hmmm, interesting idea. I would actually only need one union (which I plan to install anyway since I'm re-plumbing for a different motor height) because the pump outlet to the filter is plumbed with a piece of clear reinforced flexible hose attached with a hose clamp.
I'll have to think about the electrical connections and come up with a way to protect the coupling from the elements.
Thanks for the suggestion.
Did I say something about not wanting to create more work for myself...? D'oh!

Well, you don't have to do it all at once, if you don't want.
