Navien 240 A installed, now questions

[havasu]

I have one installed myself as well. The luke warm cold water for a few seconds is a small price to pay for getting instant hot water at my house, where our city council just raised the water rates 57%.

I have a navicirc kit (30022965A) installed under the faucet farthest part of the house, each time it closes, it makes a loud pop sound. Has anyone run into this?

Call Navien tech service

I'm not familiar with that set up, but looks similar to the Grundfos recirc pump set up. Verify the ins and outs are properly hooked up, and also call Navien. It may be a defective unit.

my two cents... Dont spend the $ for the 240a if you arent running a separate recirc line I think its $300 more. The tech bulletin is for the 240E.

I think it’s a 240s.
