Playing with a frame flush

[TJ4Jim]

Picked up a cheapo aquarium pump and 15' of vinyl hose to circulate some evapo rust across the inside bottom of the frame. Used a pool noodle and tie-wraps to close up frame openings where necessary. Been testing with water for the last
2 hours without drips so time to swap in the solution.

Very interested to see how this turns out!

So here is the final setup and it's running Evapo-Rust thru the frame now. Ditched the aquarium pump that could not deal with the viscosity and now using a sump pump with a clamp on the discharge tube to slow the flow. Took less than a gallon to setup the flow. Fluid has changed color over the last 20 minutes so the rust is on the move.
