I wonder if anybody can help me. I am having problems with my heatline
S30 Combination boiler. The connection from the three port valve to the
primary heat exchanger is leaking at the connection to the heat
exchanger. The connection is a push fit and just seems to use O rings to
make the seal. Can I just replace the O rings and should I use any
jointing agents. Any advice would be appreciated.

This is presumably with a clip to prevent the joint coming apart.
Yes if you can find the right O-ring you should be OK. Obviously you'll
need to drain the boiler down.
If you want to use something to help then a little silicone grease (not
sealant) should help.
Note that the corrent O-ring replacment may look quite a bit bigger than
the worn one.
