Hi All,
I recently installed a 1.5hp Hayward SP2303VSP variable speed pump to replace my old Pentair WFE-6 1.5hp single speed pool pump. I didn't realize it at the time but while the HP rating is similar, the flow curve of the old pump shows that it was a much stronger pump. After installation, I don't get any bubbles in the discharge until I turn on the solar panels on my second story roof. On the highest RPM of the pump, after the initial clearing of the panels, I continue to get bubbles in the outtake. On the roof, I can hear the breaker valve sucking air. I guess I don't have enough pressure to close it. Here are my options as far as I can tell but I'd appreciate any advice you can offer.
1. Install a stronger pump. I can still return the Hayward SP2303VSP I installed and get something stronger. On the highest setting, the new Hayward doesn't seem to have any problem getting water to the roof or motivate the suction cleaner. The pressure on the filter isn't as high as it used to be but as far as the function of the filter, it seems to be working fine other than not closing the vacuum breaker.
2. Replace the vacuum breaker. I don't know, maybe a new one will close with less pressure?
3. Move the vacuum breaker location. It's currently at the very highest point of the panels. I could move it to a T connector right in front of the first header so the resistance is downstream of the valve.
4. Ignore the bubbles. Can I safely ignore the leak or do I need to fix this?
If you were in my situation, what would you do? Thanks for any and all advice!
