Can anyone tell me what they think could be the issue with this pump? It’s not leaking, I’ve made sure nothing was in the impeller, and pressure is fine, heat gun registered about 115 degrees after almost 8 hours (which I think is normal) but it seems WAY LOUDER then I remember it being…. I know it’s hard to tell from a sound clip, but just wondering if anyone may know….Pump is less than 3 yrs old…. I really don’t know how long pumps will go before some sort of issues. My booster pump is the same age and already had a leak in it, so I’m a bit irritated with my pumps.
Let's see what other "ears" have to say, but it almost sounds like the onset of bearings to me.
