I took the magazine to my plumbing supply store and let a master plumber pull the necessary parts. He thought it was a great use of PVC Schedule 40.

After completing a month of Tom's Vinegar Spa treatment, I back flushed everything and watched the brown water flow!

My underdash Rexaco is showing a decidedly cooler system, even in the muggy and hot conditions in the South for the month of June!

I'd highly recommend building a pair of backflushers for the times when you don't want to demount the radiator.

Thanks! Somehow I had missed that article. I'll get the parts tomorrow!
