Here is a video of the pool pump working at full steam: https://drive.google.com/file/d/1xy2wzYSvpXmjv5pM3PqPSNuu558SkGhR/view?usp=sharing
It is a 1.85HP Hayward Tristar Variable Speed (https://www.hayward-pool.com/shop/en/pools/tristar-vs-i-pmtsvs--1)
The most it can run is 2900RPM
It appears the pipe is 1.5 inches from the skimmer all the way to the pump, but it's possible there is a 1" pipe somewhere in the middle underground. The reason I think that is because you can see that the water level fluctuates inside the pump as it's running. If the pipe was the same diameter all the way through the system, wouldn't the water level remain constant in the pump?
EDIT: Here is a video of the pool pump being shut off, and then turned back on https://drive.google.com/file/d/1aCT7ntTWhykv7Nhix5Kr3dQFQ29ms-FG/view?usp=sharing
So I figured there was a problem because the suction at the skimmer is incredibly weak. The pump can be running all day and the surface of the pool will still be covered with dust or pollen or whatever. If you put your hand at the skimmer, you can tell that the suction is just weak.
So I took that video of the water inside the pump, and it does seem that there's something wrong? Because the water level in there is low? I had a pool contractor come out and he wants me to upgrade to a 3HP pump of a different manufacturer. He tells me that will fix the water level in the pump, but will also make my skimmer much more effective
I hesitate because I don't want to spend all that money and effort if it isn't going to make the skimmer actually work. I was even considering just forgoing the pump all together and just using robots to clean the bottom and surface of the pool.
Does anybody know, from watching the video, what else could be the problem? Or is a skimmer really not supposed to be that strong in the first place?
