I looked at the diagram for the pool pump you posted. In my experience,
that large and small O-ring together shouldn't cost any more than $2 or
$3 in nitrile at any shop that sells O-rings. The manufacturer will
charge you $25 for those two O-rings as a repair "kit", but only people
that are scared to buy anything but OEM repair parts would ever pay that
much.

Yes, this is true to some degree. You can also spend hours on end
"learning" about O-rings.

You'll note the kit for his pump includes the ceramic seal, etc. What
he needs to stop the pump leak, all in one package.

If I had a deadline, I'd get the kit, fix the leak and be done with
the project. Study the history of O-rings later.

"**** or get off the pot", as they saying goes.
