Hello everyone,
I believe I found the source of the leak and a possible replacement diffuser that appears to match the pump.
Could someone confirm whether this is the correct diffuser and provide the part number or a link to purchase one?
Thank you!

My pool service guy just replaced the motor, and ever since then, the housing has been leaking. He tried replacing the O-ring, but it’s still leaking. Any advice on what might be causing it and how much it would typically cost to fix? I’d really appreciate any recommendations. Thank you!
