doughboy pool pump and filter choice

[shellymatty]

WOuld like to know what people have choose for their pump and filter for their doughboy? ALso, we would like a pool pump that runs off a 220 to be more efficient, so that a 110 is not taxed and costly. Can anyone give me suggestions as to what one to buy. And if the best filter a sand filter?
Thank you.

Pump & filter selection depend on pool size, number of returns, number of skimmers, and whether you have any other equipment. OEM pump & filter combos are ALWAYS over-sized pumps with under-sized filters: for efficiency and easy of operation, you want an over-sized FILTER with an under-sized pump -- exactly the reverse of what's typical.

You can read this thread, to see the sort of typical problem that occurs with the 'normal' arrangement:

If you use the filter I mentioned in my final post in that thread:

Hayward C12002 Star-Clear 120-Square-Foot 2-Inch FIP Pipe Pool Filter @ Amazon

with a pump like this one:

Hayward SP15922S Power-Flo Matrix Above-Ground Pump 2-Speed @ Amazon

You can run on low speed on that combo all day long, use very little electricity, and get extremely high efficiency filtration. The pump comes with a 3-way toggle switch (hi-off-lo) that you'll need when you vacuum on high speed. (There's no manual for the 2-speed version - I had to call Hayward for that info!) The same caution applies on here as in the other thread; you may have to install a valve to throttle flow back some, to keep from overloading the pump, since the filter will have so little resistance to flow when it's clean. (Contrary to what almost everybody things, pump motors are most highly loaded in low pressure-high flow situations, rather than high pressure-low flow -- when you valve off a pump, it draws much LESS electricity, than when you open the pipes wide.)

By the way, 220V is not intrinsically any more efficient than 110V, but it doesn't matter for you, since ALL AG pumps are 110V only. To go 220V you've have to switch to a IG type pump -- and you'd have to have it wired professionally, instead of just plugging it in.
