Winterizing?

3 posts in this topic

Do you recommend removing the raw water impeller for the winter?

I've heard that the anti freeze can damage them and make them more likely to fail.

What is your view?

I do recommend removing the raw water impeller for the winter or long periods of storage.  The problem is that over a long period the blades can obtain a set and will not pump properly.  I've had problems before after just one season and leaving it in over the winter where during the next summer it disintegrates so I just put in a new one each spring.

Seems to me that the effort to remove and reinstall the impeller is worse than incurring the cost for a new one.  My approach has always been to just leave it there all winter and put in a new one at commissioning time.
