HELP! Hayward Cartridge Filter

[momof2grlz]

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.

Yes, your water will be turned over more quickly. That is the plus.

Your leaks probably were caused by pressure, but good joints don't leak. To lower the suction you could slightly shut the valve between the skimmer and the pump's intake.

Another option is to downsize the impeller but the savings in electricity won't be the same as downsizing the motor. Just made a measurement on my 1 HP Hayward Superpump (circa 1997) and under full load the motor pulled 7.4 amps. Running dry at no load it dropped to 6.1A which is no great saving. A downsized impeller would be somewhere in between. I can't easily measure the true power consumption but the ratio should be close.
