New pool..dumb question! I have the 18 x 48 ultra frame and installed the strainer connectors that came with the pool. I upgraded to the sand filter that just arrived today and notice the strainer connectors allow more water to flow through...makes sense. My problem is the pool is full of water! What do I do now? Drain the water down to the lowest valve to replace them, try to replace them quickly with water rushing out all over, or go with whats there for now and replace when I drain pool next? Ive been waiting for this sand filter to get all set up and now I may have a delay...ugh!!
