RODI system leaking

[BryanM]

The connector that goes in to the RO membrane housing is leaking (circled in red), I either need to get a new fitting, or a whole new housing if I cannot source the fitting.

I probably damaged it taking the cap off to replace the membrane, something tells me I should have disconnected the hose feeding it first so I didn't turn that fitting in the housing cap when removing it :(

Are you able to determine if the leak is coming from the push-to-connect side of the elbow, or the threaded (RO housing) side of the elbow?

— Knowing which of the elbow’s two connections is the culprit dictates the recommended plan of action to fix the leak!

It is the threaded side.

It is the threaded side.

Ah!

— the elbow probably just needs to be tightened a rotation or three (unless the it’s physically cracked)!

— pulling that blue locking clip out of that elbow’s push connect side will allow you to unlock/remove the tube from the elbow fitting, allowing it to be rotated independent of the RO membrane housing!

— tighten this elbow by hand into the RO membrane housing, don’t use tools or it can easily be broken… once hand-tight/oriented in roughly the correct direction, reconnect tubing and lock mechanism, ensuring tubing is fully seated in elbow…

— pressure test and check for leaks! If no leaks are present, it’s fixed!

— if the leak persists, remove tubing, unscrew elbow completely, apply a NPT thread sealant paste to the threads of the elbow, then reinstall elbow hand-tight.. . Finally, reconnect tubing, and pressure test!

This shockingly worked.

I’ll check in a few min, but it’s on, under pressure and dry
