美国采购需求：零件及配件，泳池配件

I'm reaching out regarding an issue with my salt water system. The flow switch has cracked and is no longer functioning properly, so I need a replacement as soon as possible. I've been trying to call the number listed on your website, but it seems to be out of service. Could you please provide me with options for a new flow switch? I would appreciate any advice you can offer on sourcing this part quickly. If there are any specific models or recommendations you have, let me know. Looking forward to your prompt response, thanks!
