I forgot to mention that IF you intend to use the Intex "B Adapter", you NEED to get the 1600 gph model pump/filter. The 2150 gph model creates enough suction to open the vacuum breaker that is built into the Plunger Valves. This allows air into the suction side of the pump basket and you loose prime in less than 1 minute. If you want the 2150 gph unit, and you currently have the 1-1/4" hoses, you will NEED to use the larger strainer and return fittings, which means enlarging the holes in your liner.
