I tried an epoxy leak sealing putty in a similar circumstance but it was no good, it may have reduced the leak but the boiler still lost pressure within a few days.
Do they do 28mm push fit joints ?
I agree with ariba10, cut back so you have room and replace the section, thats exactly what I ended up doing with my leak which was in 22mm copper pipes (I used pushfit but it was tricky to wedge it all back in, due to pipes coming off there wasnt much lateral movement in the pipes available).
You may have to avoid soldering (pushfit or compression instead) the replacement pipe back in if there are any water drips present in the pipework. It usually stops the pipe getting hot enough in my experience.
Oh, the circular cutters are good but if the pipes are close together then you probably can't get a full circle on the cutter - hence you may need to use hacksaw instead - just try to get a straight cut through.
