Pump sizing depends on filter sizing AND your piping.

1. Can you take multiple hi-res pictures of the pump pad AND the pool, showing the pipes from multiple angles, and the liner damage, skimmer and returns? Post them using a link to Photobucket, Picasa, etc or email them *full-size* to poolforum@gmail.com.

2. Would you rather spend more now, to save $$ over time, or do you need to minimize the immediate cost? Cost range for a pump / filter / timer combo with valves will range from $800 - $2000. There are lots of options -- for example an over-sized filter coupled with 2 speed pump and appropriate timer can BOTH reduce electrical costs significantly AND make the pool easier to maintain.

3. Do you want to do the work yourself, purchase the equipment yourself but have the work done by a contractor or handyman, or hire it done completely. It's often tough to get pool guys to do it your way, but currently Pentair has drastically cut the warranty on consumer purchased gear, meaning you'd need to pick Hayward or Jandy gear instead (not really a problem, but just saying.) The Whisperflo is a Pentair product.
