I’ve used my March pump for probably 80 batches now. Circulate the last 15 minutes of boil then go to chill while continuing the circulation. Never a problem. Then maybe 10 batches ago I’d get cavitation from the boil maybe once During the 15 minute boil, bleed and Then all good. But over time it has gotten worse and now I can’t use the pump at all during the boil. Works fine at just under boil but as soon as there’s any simmer/boil it cavitates and I need to kill it. Nothing has changed in my brew setup. I’ve changed my QDs just in case, taken the head apart but it’s clean. Motor runs fine, quiet. Just the loud noise it makes at cavitation then I quickly shut it down. Any ideas?
