Product Questions

I've noticed that after 1.5 years, my 20RT is precipitating salt out the sides, indicating to me that it may be leaking. I plan to remove it and clean it soon, but if the gasket has gone out, where can I get a replacement? Is it as simple as getting a new o-ring at the hardware store, or will I need to order a part from the manufacturer?
Question by: Eric Anderson on Jun 9, 2017, 4:19 PM
It does sound like the seals may be aging. We don't currently have replacement components for these pumps. For assistance with parts, we recommend reaching out to Iwaki directly.
