Hello Greg,
Since I am not doing any high rise work "yet" I have not been
involved in the pool connection issue. I do know most of the new high
rise buildings built here in the last couple of years have a line from
the pool to the Fire Dept access point so the pumper can connect and
draw from the pool if needed. I am talking about Ocean Front properties
where the water table is 10-12 feet in places.
As a side note we do service a property where the pool is the
only water supply, Even has a vacuum pump tied into the supply side
line of the pump to prime the line. When it was built it was far enough
out there was not any city water supply and the pool is filled from
the well.
