Where to get a Dart Pump serviced?

Honestly, like nothing. You open up one side, clean, re-lubricate, reseat the seal and re-assemble. Its quick and easy, you just need the right tools.

There is a specific lubricant you're supposed to use though, or specific type, I think it might be liquid graphite, and I know we got ours at the hardware store, but you'd have to double check that one.
