Replacing a motor on a pump, and getting the correct size for your pool?

[mas985]

My mistake. Waterway evidently decided to do things differently than most pumps and flip the seal. I just assumed they were the same and I shouldn't have.

You had the seals installed correctly although you need to make sure the white ceramic seal is bottomed in the impeller. The surfaces need to be perfectly parallel when they meet. Also check the seal surfaces for any damage.

Should there be an o-ring or any sort of silicone sealant behind the spring seal?

That should have a rubber seat so it should just be clean on both sides. They do make seal lube that is designed so the seals insert easier but it is not a sealant. In fact, you want to avoid and sealant to prevent issues with the seals. Only use the lube that is designed for the seal but that should only go in the rubber parts and not the seals themselves. Those need to be kept clean of everything.
