The 2hp Challenger pump that looks to be original on my pool (22 years old) sounds like the bearings are starting to give up. The 22 years in the desert sun have made the motor tag unreadable and much of the plastic very brittle. So I'm at a bit of a crossroads and could use some advice.
I see a few possible solutions...
1. Rebuild motor
2. Replace motor - I've pretty much ruled this out due to the cost compared to a new pump
3. Replace with new Challenger - although I don't know if its a High flow(head) or High Pressure?? I think High flow...
4. Replace with whisperflow - they are quiet, but is the challenger a "better" pump? I'm curious because the whisperflow is cheaper...I certainly want durability.
5. Replace with Intelliflow - with the rebates locally, it is only a couple hundred more. See issues below.
I'm having trouble seeing how I could make the intelliflow work without major piping changes as my pump intake has a single valve from the pool that adjusts between the vacuum port (for my floor cleaner) and the skimmer (which I assume is connected with the main drain). On a slow pumping speed, the Intelliflow wouldn't run my cleaner.
