I have a question about my T135 you might be able to answer.
I've been messing around with my VS pump RPMs to guess my GPMs. The heat pump is rated 30 GPM to 70 GPM.
When I get to 1230 RPM, the heater goes from No-Flow to On (I hear the fan kick on). However, when I kicked it up to 2300-2500 rpm, I heard the compressor come on (which I thought was already on). So now I am a bit confused as to what it is actually doing and where my flow rates are. I assumed when the unit turned on at 1230 RPM, that mean't it was 30 GPM. Maybe I was wrong and 30 GPM is when the compressor kicked on.
Here is what I was able to record.
RPM / PSI (at filter)
1230 / 2.7
1400 / 4
2000 / 9
2300 / 12
3000 / 20.5
3450 / 27.5
Here is my pump.
My pool is above ground, but the plumbing runs underground to an equipment pad (approx 30 ft).
