Navien Tankless Recirculation Pump leaking! Help !( pic included)

[Taylor67]

Hello there,

I am have a minor leak with my system and it is coming from the recirc pump... Included is a picture with an arrow pointing to where the leak is. It is a very minor leak about a drip every 15 seconds. My question is if there is something i can do ( tighten perhaps? ) or if i need a new part or a whole new pump unit. I believe it is the air vent on the recirc pump that is leaking.

Any help would be appricated!!!

I work with Rennai tankless units mostly but I believe those have a little gasket in there don't they? If so, that would be the first culprit I would suspect.
