Thetford sells a service kit that includes 2 seals & a new blade. Haven't ordered it for my leaky macerator yet but check their website & know your model #. You can also download a "dismantle" instruction pamphlet that would've saved me a bunch of headache had I known about it when I took mine apart last yr.
Congrats on your unit. We are in the process of trading in our 2008 2551 for a new 2552.
If you don't see discussions ragarding what you need to know about your unit on the forum already - just ask; there are plenty of owners w/way more experience than me whose recommendations I've already taken to heart.......
