When purchasing from online retailers, please search for their address. If it is a motorhome, a house, or a UPS store, please dont support this type of business. Water treatment equipment should be purchased from a company that actually services, installs, and maintains equipment, not just shuffles paperwork and maintains a website. No overhead, no employees, no stock or inventory, etc. Just some guy in his underwear eating cheetos and forwarding over orders to a distribution house.
You got a 32MM distributor, (high flow) and a 1.05" top screen. This is a common mistake, mixing top screens happens since there are 4 common sizes for residentail applications. 13/16", 1.05" (same as 3/4" PVC), 1.25" (same as 1" PVC), and 32 MM (1.26" OD). They should ship you out the new screen without a problem.
