I have also just completed a repair test job like you , I welded (suflos) extensions onto where like your rubber hose clamp extension is and 75mm long (mine were OD 25.4mm and the new ID 25.4 ) fitted perfectly and simple to weld up. It must of been old copper in the pipes as its OD measurements.!?? The Absorber plate was removed from the casing to do this of course. I did this to each Header and crox nutted them so i could easily do a Pressure test without any Money wasted on plugs , however i had to hire a small Welding set to do it , I had everthing ready to go before i picked the set up. I pressure tested it on the mains water supply here before it goes through a Pressure reducing valve in our plumbing system. It passed perfectly . It was probably a slight over kill on pressure but its 100%.
