NAVIEN❗--- INSTALLING A TANKLESS WATER HEATER🔴 

This was an exact replacement for the old one that lasted about 10 years.

Good install! But just a warning to you or anyone else looking to embark on this journey of installing a tankless water heater yourself; if you’re not a professional plumber you will get ZERO warranty support from the manufacturer. I installed my Navien myself in 2019 and it’s been perfect, but just keep that in mind.

The manufacturer recommends you do a combustion analysis on these units followed by an adjustment of the gas valve or different orifice used if needed. This is one of the advantages of having a professional install

I’m learning how to install, just wondering if a check valve go before the expansion tank?

might it have been easier to install the valve set , while off the wall, up side down ?

How's it holding up?

Is there a maintenance schedule for the condensate neutralizer? Does it need to be changed periodically?

Should have put all fittings on before hanging on wall.

My Navien takes around 40 seconds to ignite, is that what your seeing?

I'm installing a navien at my house. My hot and cold fittings were loose, just this the in the video @

The plumber jut installed a Navien gas - does it not require a "metal double wall exhaust flue" as this exhaust is HOT ?? thank you ! nice viedo !

No flares?

What was the clear cylinder with all the pebbles in it?

He shouldn't be using dwv PVC fittings. Only PVC Sch 40 to match the pipe. Many of the dwv PVC fittings are made of a thinner PVC. Navien mentions this in their install manual.

You have absolutely got to use pvc solidcore pipe! You cannot use regular pvc dwv piping!!!!! It’s a condensating tankless unit and that vent pipe is not rated for a Navien!! Read your manual!!!

The video is very good. One question. I see more Videos of these because some use an expansion tank and others don't.

I just can’t believe that people still use sea PVC pipe. Worst thing that was ever invented.

What was the extra tank for and I didn’t understand the hookup of the filter?

That condensate filter is plumbed all wrong.

Where is this and who uses cpvc anymore? Well water? Use a tank. You'd have to flush that thing every 3 months with a filter having well water.
