Replaced o ring on Navien 240-A

[Proma]

Hey All

I replaced the T adapter + oring on it and had to remove a few set pipes/adapters to do this.

When I turned it on to repressirize the unit, water shot everywhere.

It’s now leaking from connectors it was not before. Is there a trick to setting those rings or how did I mess this up so badly?

This unit is from 2009 so not sure if all o rings are just tapped out now or what.

Please help before wife wakes up to no water…lol

Having taken dozens of parts using the “C” clips, I can assure you that when the o-ring is in the proper groove and the parts go back together, I have NEVER had a leak or bad experience. Leaks would only occur if you did not put things back or if the o-ring rolled out of place. Good luck.
