Hi guys my ace system is leaking from where the front pipes join into the valve block. The pipes are in very good condition. I was to before to replace the collects. I have done this but it is still leaving. When I changed the collects one of the pipes seamed to go into the valve block more than the other 3. I had to prise it out a little bit to fit the collect but the other 3 just slipped on. Am I right in thinking that the other 3 should of been like this one and that they are not sitting into the valve block right and that’s why it is still leaving? Any help would be very greatful as I am going to have another try at fixing it tomorrow morning.
Thanks again

The collets don't seal,they hold the pipes in place,there is an O ring inside the valve that seals the pipe.
Hope that helps.

I only know as just my pipes
