I'm still on the fence, everything I read states power companies bill consumers based on real power and not apparent.

Here's a little quote from a website that talked about power factor...

It is actually up, it never sold so I decided to use it. At the time I was under the impression it was efficient, regretting it now.

Front and back = 18x20
Bottom = 18.125x20.125
Sides = 17.5 x 20 (x2)

Watt meter on the pump reads 82W, same meter reads 1.8A & 115V

P = V * I * PF
So PF = P/(V*I) = 82W/(115V*1.8A) = 0.4

If you plug the pump into an energy monitor it reads 82W but it pulls 1.8A. So the question is as far as the power company goes are they billing me for 82W or 1.8Ax115V=207W

Thanks let me know :)

I can't tell you how ****ed I'll be if this pump is actually costing me over 200W of power.

That sounds like its only applied to commercial use, being billed based on kVA and not kW.

Ok now we're getting somewhere. My assumption is I'm getting billed in kWh which would include PFs so if my pump is using 82W I'm paying to 82W and not 212W. While the pump is pulling 1.8A it's not...

It depends how you want to do it.

You can buy a relatively cheap plug monitor from CT for $20. You'll have to measure things on a device by device basis or you can measure full power bar at once...

Also the line that feeds up towards the ceiling is from the lower RD return pump, it will later feed a small tank on the floor above, hopefully it makes it.

Looks off to me as well, but the current was measured with my profilux PAB and an energy monitor. Both read the same amount of current which is around 1.8A for the RD 6.5. Since both devices read the...

Wow that's kind of dumb. So basically 90 gallons or less and nothing rimless. So anyone with an in wall tank large enough to actually want one can't. Seen this years ago never noticed that detail.
