Owner and architect decideOwner and architect decide- aesthetics- aesthetics- conformity- conformity


• Goals

• Explore current system- complications- possible long term effects

• Suggest a less expensive alternative that is just as effective


• Goals

• Current system

• Issue with vertical rise• Splashing at air gap connecting pool line to sanitary line• Expensive solution

– bring in tank– indirectly tie 6” pool line to 8” sanitary line

• Possible long term effects– decomposition of sanitary line (?)– corrosion of steel decking (?)


• Goals

• Current system

• Alternate solution

• Add another line going to sump pump (proper vertical rise)

• Install new sump pump– handle 430 GPM – break open floor– connect sump to pool trap line– already tied into sanitary line

• Cost comparison

• Current system information provided by PM and Mechanical contractor

– 12’ polypropylene tank w/ 64” diameter– 1.5 HP pump, infrared beams, and electric switches– labor and installation

Total Price: ~$35,000
