While trying to correct some chemical problems in my pool I decided to replace the sand in my filter, only to realize that the 300 lbs of sand needed was the same amount I had in an earlier 25 K pool. Turns out the pump/filter were not part of my chemical problem, but I was concerned nevertheless.
I went to the Hayward website and used their 3 page worksheet to determine the correct size pump and filter. Bottom line is I calculate my 12 hr turnover rate at 28.8K gal and I have a 55K gal pool. I run it 24/7 from season start to finish, so I get a full turnover every 24 hours and do not have to backwash more then every week or more. Pressure goes from 16 psi to 22 psi before I backwash since letting it go over 22 psi really drops the flow.
I contemplated going to a full rated 1.5 HP Hayward High Efficiency Superpump and would need a Hayward 700 lb S360 filter to handle the flow. My pool has only 1 1/2 piping with 2 skimmers and 1 main drain each on a separate line, so the total head from the suction line runs is high. My shortest suction side run is 5-6 feet and the other 2 I estimate at 65' and 85' feet, so I am not pleased with the builder! Is 2" piping too much to ask for crying out loud. 4 return jets, teed 2 to a return line.
The builder says his pool is the same size as mine and he has the same equipment I do. He strongly recommends running 24/7 for circulation and lowest chemical useage. Since the filter does not need backwashing any more frequently then my old 25K gal pool it does not seem to me that the filter is plugging up with crud too often.
Pool was built in 2006. How important is a 8 vs 10 vs 12 hr turnover rate anyway? Any suggestions on what I ought to do?
