[@armandomadrigal9793]

Im an old Timer, and i just love, not only to press copper, but also mega press, best thing since sliced bread

[@brianfreeland990]

“ I’m not a professional, that’s why I use press.” Very humble of you bro🤣 I know you have soldered your fair amount of joints lol Good job and great video.

[@mateo801]

Good work! Thanks for sharing!

[@DIYWithTheRichardsons]

You did an awesome job job bro but leave the electrical to us electrical contractors remember next time ground that metal box if a hot wire comes loose and contact that box it will energize the outside and potentially hurt or kill someone but other than that great video!!💪🏽

[@dantoubiana3286]

Great job and thank you

[@DOLPEDIY]

Thank you too!

[@amytaylor4992]

Great Video! Thanks! I didn't see any drain lines attached. You told us about the acid neutralizing unit but where does the neutralized material go?

[@DOLPEDIY]

Thank you! At marker 19:20, the white box at the bottom is a special condensate pump. It has acid neutralizing beeds inside. The discharge is piped the the stand pipe of the washing machine drain.

[@frankprovenzano7029]

Great video. Easy to understand.

[@DOLPEDIY]

Glad it was helpful!

[@rons8098]

Great work great info! Well Done!

Thank you!

Really clean work man I recently took a class with navien and they said not to hook it up to a gfci to use a regular plug what are your thoughts on that I’m not against it I’m just curious

[@DOLPEDIY]

Our local code states that anything deal with water must have a gfci. It will fail inspection without. I also confirm with my father who is a licensed electrician. That's very interesting though I'll look into and get back to you.

[@DOLPEDIY]

So according to the navien installation rep. " I believe by code if it is the only outlet in the basement it has to be gfci, it can cause nuisance calls. So we teach them in class to avoid them if you can. But sometimes you have to use them. "

[@loobydude]

@@DOLPEDIY In a basement the NEC requires all receptacles to be gfci protected except for the one for a fire/security system. Just because someone at Navien says something different it doesn't matter. The code comes first.

[@mitchellmckinney7872]

I watched so many videos and almost callled a plumber before I found this video than you so much.

[@DOLPEDIY]

Anytime!!

[@PhilogusRex]

As a fellow plumber, this video's got to go. They know too much so now we're obsolete 😂

How do you decipher if intake pvc run can collect to the basement or has to be outside

[@DOLPEDIY]

For a Navien tankless water heater, it's generally recommended to intake air from outside to ensure proper combustion and to avoid drawing in potentially contaminated air from the basement. However, there are a few conditions under which you might be able to run the intake inside the basement: 1. **Adequate Ventilation:** If the basement has adequate ventilation and fresh air supply, you might be able to use indoor air for combustion. Ensure that the room has enough openings or vents to bring in fresh air from outside. 2. **Local Codes and Manufacturer Guidelines:** Always check local building codes and the manufacturer's installation guidelines. Some areas might have specific requirements or restrictions regarding indoor vs. outdoor air intake. 3. **Avoiding Contaminants:** Ensure that the air in the basement is free from contaminants like chemicals, dust, and fumes, which could affect the performance and safety of the water heater. 4. **Space Requirements:** Make sure the basement has enough space to provide the necessary air volume for combustion, as specified by Navien's installation manual. 5. **Sealed Combustion:** If the unit is designed for sealed combustion (direct vent), it typically requires both intake and exhaust to be piped directly to the outside. It's always best to follow the manufacturer's instructions and consult with a professional if you're unsure. Do you have a specific model or installation scenario in mind?

We charge $6500 in Brooklyn to do this install...good job

[@DOLPEDIY]

That's about the same we change Herr in Jersey

[@DamianIacano]

@@DOLPEDIYincluding material?

[@tubegoood]

Nice job.

[@DOLPEDIY]

Thanks for the visit

[@rcmechanialgroup2856]

Looks good man. Any reason why you didn't make the plywood backing wider instead of longer so you didn't to drill into the cement to strap the pipping?

[@DOLPEDIY]

Damn that's a good question. As I'm reading that comment I'm asking myself the same dam question. What the hell dude where were you when was installing this. I blame you!!!! 😁

[@rcmechanialgroup2856]

Haha. Its all good. Sometimes when you see things from a different view it hits you. @@DOLPEDIY

[@steveh.9170]

why not pex? just curious.

[@JustinTBowen]

Was the new gas line galvanized? Looks very shiny compared to black pipe.

[@DOLPEDIY]

Yes, it was for the outside work.

[@Tom-xr2rv]

Does Navien has a propane gas tankless water heater? Thank you.

[@DOLPEDIY]

Yes they do. All of their units can be converted to propane.

[@ahmad7825]

Please share nail gun you use...

[@robertkifan4376]

What size gas line does this unit require to run? My line is 1/2 right now and in about 10-15 feet away from the meter. Do I just size up to 3/4 gas line off the 1/2? Thx in advance

[@DOLPEDIY]

That all depends on what tees off between the gas meter and where the unit will be. With this unit, you can use 1/2in but that's at the last run to the unit and it has certain requirements for that. A gas load calculation and diagram would have to be done first.

[@peterguarinio3632]

@@DOLPEDIY What if it's LP and not gas? I have a 30' length of LP pipe and not sure if I should upsize to 3/4"

[@Dudjrkfjjffjkffu]

I’m curious why you didn’t just mount everything on the block wall. Tapcons are about as strong as it gets.

[@DOLPEDIY]

mounting on a board provides stability and protection, while making installation and maintenance more manageable.

[@Dudjrkfjjffjkffu]

@@DOLPEDIY how so? The wall shouldn’t go anywhere. And installation and maintenance is the same either way. I’ve installed probably 100 of these units and serviced twice as many. The wall you built is only as secure as the surface its mounted too. It’s a good installation nonetheless, you did a good job.

[@brokensmile8487]

Dont you want the internal recirculation running?

[@DOLPEDIY]

we hooked up a recirculating line 2 days later. I will upload that video soon. Maybe. 😁

[@brokensmile8487]

@@DOLPEDIY oh, I see. I didn't think you needed a recirculating line for the internal circ. I'm learning but great video and looking forward for more videos.

[@westcoast708]

I just got the navien npe 240 s2 he only vented the exhaust pvc intake is just basement air my unit is in my furnace room is that ok ?

[@DOLPEDIY]

Depends on the size of the basement and if there are any other combustion units down there. A combustion test would be needed. But if it's possible, it's best to get the intake outside. It's better for the unit.

[@erniecollazo3849]

Pressure relief leak on navien 240a Unit 5 months old . Normal or what

[@DOLPEDIY]

Are you talking about the temperature and pressure relief valve? If so, then it should be on for safety.

[@JESUSWORD2]

No, that's not normal. I would check your pressure. If it's above 80 during the high times, then you will need a PRV.

[@erniecollazo3849]

@JESUSWORD2 God bless you brother 🙏

[@czogg99]

What was the cost for installation.

[@DOLPEDIY]

This can be between six to nine thousand. Every situation is different.

[@erniecollazo3849]

Prv regulator I changed it thx

[@tedbear8168]

Your install is missing one thing. A level ! lol good install

[@DOLPEDIY]

Lol don't tell anyone!!!! 🤣

[@gusbalcazar4927]

A professional puts down a drop cloth and doesn’t use a sawzall to cut 2X4 they use a circular saw. A professional uses proper tools. I’m a professional plumber that how I know. People expect to see a crack, so give them what they want.

3k for labour, damn I’m in the wrong business!
