My knowledge of pool equipment is limited, so I apologize if I’m not making sense. We need to replace our cartridge filter and pump that came with our 15 foot above ground pool. We currently have one that has red handles by the in and out hoses that can stop water flow. I have attached photos below. When looking at new ones to buy I’m not seeing many models that have these and they don’t look like I’ll be able to attach my hoses the same way. Can I take these off my old pump and filter? What are these specifically called so I can be looking for the right thing? I like the ease of hose attachment when using these. The first 2 photos are examples of the things with handles and the last picture is a pump and filter combo I want to buy. Does it seem like I’ll be able to attach these to this new one?
