Thanks for your input, Carl.

On one hand, I'm glad the PB traded out the pump. We had already had (3) service calls for the pump leaking and I was afraid we got a lemon. Now I think the leaks were possibly being caused by the excess pressure caused by the defective cartridge.

At this point, after finding out the problem was the cartridge (C1200), I'm a little displeased that they upsized the pump before checking the cartridge. I know this pump will turn the water over much quicker, but I already figured it would use more electricity and seems to be slightly noisier. It also makes vacuuming a little more difficult because now there is sooo much suction.

I'm hoping the trade-off will be that the run time can be less since the water will be turned over quicker. Is there any logic to my optimism?

Thanks again. I'm so glad to have found this board. I'm such a novice and it's nice to have somewhere to ask questions and not be treated like a total idiot.
