Default A PERFECT Navien CH240 installation??

The Zone is a hard core site with some of the best plumbers in America as members. I think we can agree that there are both very intelligent guys here and some that like to display their superior intelligence rather than post new articles. My buddies and I are focused on high efficiency water heating products. Depending on what kind of person you are Enjoy, or over analyze this.

[I]Intro: An unqualified "plumber" did a horrible job installing this navien CH240 almost almost 2 years ago. I cannot even list the issues, literally everything was wrong so we took it off the wall and started again. Although there was no fixing the this Navien per say, We're certified Navien repairmen for the Greater NYC area



















Thanks for viewing.
If this isn't a perfect installation I challenge someone to show me a better one.

Your venting would not pass code here to close to the opening on the left

Kinda sad to think you are walking on water just to find out it's just a shallow puddle.

Never challenge the zone inspectors to find fault in your work.

Having the relief valves tie into that condensate pump really ain't the best thing to do, considering if 1 of those relief valves open up close to full-bore theres gonna be one hell of a mess in that room.

That vent on the back flow preventer is tied directly to the relief valve piping! Now it's not protecting anything, you actually made it a double cross connection..

The relief valve is dumping to a condensate pump (not rated for that kind of temp)

Then the condensate pump has that vinyl tubing stuck into a stand pipe that isn't tall enough, just waiting to syphon that trap out once the check in the pump fails..

So you have the "backflow device" potentially cross connected to boiler water and the sewer in one shot.

Also jay never say you did a perfect install on here in the zone, cause the word perfect here don't exsist, IMO there's always room for improvement somewhere, although that is great work and I know I probably couldn't do that, there's always room for improvement

Just my thoughts.
