OP you mentioned using a cleanser but did not say which!
They are not all the same.
DS40 is about the only one likely to work but may cause leaks.
I dont think you realise just how bad your system is!

Fair enough . You won`t make it worse flushing with a hose , but connecting hoses to drain cocks isn`t the most fluid tight thing . I`ve had some sucess in the past by using plastic (speedfit) pipe and fittings and rigging up temporary in /out pipesso I really need to keep this relic going a while longer!
do you recommend trying to flush it with a hose?
could I make it worse?
