Big Rock Waterfall

Picture
This is a Remodel.  Existing 20x40 vinyl liner pool originally 8' deep.  The customer wanted to change it to 5' deep for safety reasons.  We took out the old liner and removed the main drain.  We added crush and run gravel and compacted it every 4" until the depth was 5' 1/2".  We then installed dual main drains to prevent entrapment.  We added 1.5" of Pool Crete across the whole bottom and installed a 28 mil replacement liner by GLI.
A custom rock waterfall was added and the diving board was replaced with a jump rock for added safety.
The old pump and filter system was removed and replaced with a variable speed Flopro pump and cartridge filter system by Jandy.  When the waterfall is on, the pump can be turned up to 2HP to handle the extra volume.  When the waterfall is off the pump can be turned back down to save on electricity. 

Automatic Polaris cleaner system is on a timer.
