Q:Will this part replace the 28512 1000 GPH cartridge in the 32101 housing?Asked on 6/15/2009 by Anonymous
A:The 500 GPH and 1000 GPH cartridges should be interchangeable, meaning either should fit within the 1000 GPH housing; however there is a performance difference in the GPH (Gallons Per Hour) rating. Please be sure the cut in GPH is acceptable for your application.Answered on 6/16/2009 by Matt from Overtons
