We had a new pump/sand filter system installed about seven years ago when the original equipment (Pump and cartridge) rusted out (the old stuff was over 20 years old).
Had no clue about pools at the time and trusted the pool company for the choice of equipment which I am thinking may have been a mistake.
We have a 17k-18k pool (math seems to place it around 17.5k including spa) and they installed a 1.5hp Pentair WF-26 and a Pentair Triton II TR-100 sand filter.
I have always been unimpressed with the degree of filtration this setup has given us but when I have asked around I have been told "Sand just doesn't do that good of a job" (which in turn made me wonder why they installed it in the first place) but now that I am taking the pool more seriously I started looking into this and am now wondering if the pump may be too powerful for the filter.
Looking up the specs for the two it appears that the TR-100 sand filter is rated for a flow rate of 98 gallons per minute, while the WF-26 pump outputs roughly 135 gallons per minute. Nearly 40% more than the filter is rated for.
Is the additional amount of water running through the filter potentially responsible for the poor filtration results?
