Had my pool resurfaced and in the process decided to switch all my pop-ups from the Original MagnaFlow to A&A Gamma Series 2 pop-ups.
Afterwards I'm seeing much lower max pressure at the Valve.
So before running my Pump at 2900 RPM I would typically see around 20PSI at the Filter newly Backwashed and around 17 PSI at the Valve. After switching the heads, I'm seeing 12 PSI at the Valve.
The heads seem to operate fine in my pool except for in my SPA which has a poor design. Basically the SPA has 6 popups all operating on the same port and in addition it sits much higher than the pool does. Since the A&A Gamma Series 2 are adjustable, I had initially set them to 3/8" Orifice rates at 12 GPM comparable to the old heads (Low Flow). I tried to set them to 1/4" Orifice rated at 6 GPM, but the result remains the same. They worked with the old style head.
I have checked the Valve for debris and functionality after the resurface, but didn't see any issues. I have also cleaned the filter (Cartridge) thoroughly The only reason for the lower pressure that I can think of is that there must be less resistance in the new heads, but I don't know if that is plausible since they are rated at the same GPM when adjusted to the same flow rate as the old ones.
One theory I have is that the older style popup had a weaker spring and it was easier for them to extend. The new style seems to have a lot of water escaping if they don't extend fully.
Any suggestions for trouble shooting?
