In your 2021 Appendix A you describe removing the hoses and or pressure relief valve from the Alde. unit. How is that more effective than pumping water or new glycol through the system? Do you think that old glycol could otherwise remain lodged in the Alde or in the lines someplace while air and fresh water passes through the system?
I will try to call Alde and see if someone can tell me what is inside the Alde unit, does the glycol flow through a coiled pipe inside a burner box, or does it go into a tank that might retain glycol when flushed? Same question for the Flow unit, whoever makes that. Otherwise I do not see how flushing from the reservoir could not push 99% of glycol out.
