My PB just set my equipment on the pad. I am using a Starite S7D75 De filter. He did a nice clean plumbing job, but i noticed he used a 1.5" multi port instead of a 2". When I questioned him on he said since Im using a 1.5hp pump and my pool is only 25ft from the pad it will be ok. Not sure if he is trying to save a few bucks or just ordered the wrong one. Pipe is all 2", I have main drains and 2 skimmers, no spa or water features plumbed into this line. Pool i guess is going to be in the 20,000 gal range, it is free form and has a large sunshelf, so not sure yet. Any opinions would be appreciated.
