the use of blue dope for my listening pleadure...love it
Blue dope for your pleasure. Makes me chuckle every time. Steve called it smurf jizzum in a video the other day
Awesome how everyone references Steve Lav, he’s the OG! 😂
Was hoping you'd get into the programming. I installed recirculation plumbing on a 5yr old unit and set to external/dip switch 2 up and it works when you open the menu and as long as the menu is open but soon as you back out it stops circulating. Seen in another video a guy had the actual instructions in his book how to set the parameters of how long you want it to circulate, but you only get a glimpse of his page . In his comments were people who said those instructions weren't in their book, as it's not in mine either. My customer wants it to circulate all the time and always be hot. Guess I will keep searching, thanks.
Nice job
Great job, been watching your channel for a while now, great work. quick question i'm building a new construction home and had a npe-240a installed with a dedicated recirc. line. I have the valve to ext. recirc inside the unit and dip switch 2 flipped up for on. What causes the milky white water out of the hot water line, is that excessive air in it. They didnt install any type of hose sillcock on the recirc line at the unit like you did, how would i bleed the air from the lines if thats whats causing that milky white hot water. i have that bad on initial start up today. I know theres a small black bleeder on the bottom of the 240a that connects to the ricirc pump maybe i could use that. Many Thx.
There is actually a bleeder inside the unit, above the pump.
MEGALOCK! One of the best dopes I’ve ever used
I found real tuff easier to apply... and its super thick. but im just a DIY'er. always ready to use, megalock seems to need to be mixed alot. I believe they are the same compnay?
Megalock is for guys who don't know how to tighten a fitting.
@@f.demascio1857 shots fired :))
I like to gorilla/hercules tighten pipe threads myself
All pipes should be sleeved through the blocks?
I have a Navian 240a like you installed with external recirculation line. I am also using the intelligent mode as well. Over the last 6 months when the pump turns on to recirculate, I get a pipe tapping noise, like when air is in the line. Would you happen to know what may be causing this to occur. The system was installed by local gas utility company, and they used PEX including foam insulation. PEX is strapped down, nothing loose that I am able to see. Thanks in advance for your support.
Could be air or could be expanding of Pex on hangers
Good job, looking nice and neat.
Do you need expansion tank on hot water loop?
Great video, love that crimping tool you have, awesome!!! I just ordered a 240A2! Does the recirculating line tie into the furthest hot waterline from the heater and come straight back to the heater? Also, what is used to tie in the return line, an ordinary "T"? Thanks !!!!!
Yes and yes
@@MiHeatingGuy how does that work on a cascading system with 2 units? would you just T off that to the slave unit before that drip drain you installed?
Those Naviens are not kind to Teflon tape.
I usually put it on with unit upside down.I have a video of a side x side cascade system if your interested.
Great job guys.
Looks professional.
Teflon tape blows.
the line coming back for your recirculation , at the bottom of the wall is just the return from the rads or something ye?
how come no spring check and exp tank on cold feed because of recirc line
Everybody thinks it’s easy
well figure overhead

Love the video. Quick question. Where/how do you tap into the line at the furthest point? Just splice into the hot line at the furthest point with a T fitting?
Yes
@@MiHeatingGuy thanks. I have to do this asap. We are on a well that is very low producing. We are wasting tremendous amounts of water waiting for hot water to reach the faucet for showers and washing hands. Do you know how much extra propane this uses circulating all of the time?
Wouldn't even notice
Best help I found, 3/5 if you redo the video and make it shorter and do a little bit cleaner explanation would be a 5/5
a little dope, a little fritz
I'm debating on having a Navien npe-240a2 installed is this a good unit for a 2800 sq ft 2 story house with 3 bathrooms? Does one need to run a condensing drain pipe? How often and expensive should they be serviced? Do these require flushing valves? Also looking at the Bosh Greentherm T 9900 SE 199NG. Which is better and going to last longer?
The Navien, hands down.
have you ever installed an H2AIR on an NPE-240A? supposedly you can use an NPE like an NCB for a space heating zone using the recirc provision, internal pump..
Not code in Michigan
It's generally a bad idea because you're using raw water constantly in the heating loop. Everything rots out and fails if you don't have really good incoming water.
When you say "Recirculation line" is that the By-pass you are talking about? Or is it the Return? Sorry, I commented at the start of the video, should have waited, DUH!!
The bonus....blue dope twice
I'm surprised you don't insulate the return and supply piping on that loop.
really not much sense in it, the recirc. pump is built into the unit and only runs when water flow is sensed to quickly get hot water through the loop and back.
you wont really save diddly with the lines insulated, as compared to a standard tank water heater and recirc pump that runs for hours on end or 24/7
Thank for the blue goo Joe we r pleased lol!
Hi sir, Does it matter where I grab my cold and hot water or can I grab it close to my shower. Under the house it’s all 3/4 copper pipe
You can
@@MiHeatingGuy one more question sir I connected my cold water to my cold and my hot water to my hot and my recirculating line to my furthest point but when I turn everything on my cold water gets warm and my hot remains hot
It seems like my hot water is somehow getting into my cold
Could it be something is crossing
trick 1 use a pen roll some Teflon on the pen then unroll to fitting
or screwdriver/nut driver, extension, small tubing/pipe, your finger(if wrapped the right way lol)
Pro press for your pleasure
Ok
No tape? How dare you lol
Why set to external? Aren’t you using internal pump tho?
Using an external line but internal pump
ok so I used a astro valve under furthest sink or navicirc would that need to be set on external?
Don't mind me but u tie it in on the cold side
put the newbie in the crawlspace working hard LOL
Slather it on!
There is nothing like the blue dope girls
sounds like something from breaking bad :))
all the batteries dead on the job site, sounds familiar. (points finger at my friend, whom never charges them and then we waste 45 minutes going through them and charging others) lol
Always, always, always insulate the return line and all accessible hot supply lines. That unit checks temp in the line and will recirculate to keep at temp so you want to limit the cycling of the unit.
They mean just flip #2 on.. remember it's translated from south korean...lol
🤦♂️
When you say we got Mike or you got Mike. Are you referring to the Mike? As in Mikey Pipes?
I think you and Mikey Pipes should have like a boiler, furnace, AC, plumbing, sewer, CZcams service repair Fest. You could give away a bunch of stuff like a fully stocked van with tools and all kinds of stuff.
He Is not welcome on my channel
@@MiHeatingGuy sounds like he's making all sorts of trouble. He's doing some BS over on Steve Lav's channel
He started doing this crap back in November He was doing same thing of my channel that he was doing on Steve's channel. The guy is a complete dirt bag
I was kidding .... Kinda like a joke. . .
Sorry.
Kinda saddens me cause he does a lot of steam boiler work which right up my alley. I think he is mellowing out after Lav's army responded negatively.
I'm the first one. Yay!
not to bash, and I know there are youtube nazi's about this, but why don't you ream your copper before propressing? I thought its critical for that. (Not a professional what so ever, just like plumbing and DIY
