TSP at Lowes

I found both kinds with and without phosphates at Lowes. I'm using it to flush the system out and run it untill I get an order of Rhomars Hydro-Solv 9100 and then use the Pro-Tek 922 to keep in the system.

It is a 50 year old cast iron rads system with a new Munchkin T80 with indirect.
