Mikey Pipes and Steve Lav are wonderful assets of the mechanical UA-cam community.
Thanks
Peter has a great mentor. Lucky to have him under your wing. Great lesson for us as well. Even gave Steve Lav a shout out. 😂
Give credit where credit is due.
Glad to hear you giving Steve Lav some props. he ain't you but he gets the job done for the customers in his market
Credit due when deserved
My first boss always wanted the jacket top always wiped clean before leaving the job. It was impressive for the customer to see a clean boiler jacket and it wasn’t hard to do.
These types of videos are essential for new techs, and great refreshers for experienced ones.
Glad you think so!
Excellent work
Thank you! Cheers!
By the time you got to the roll out switch I'm like wth are you doin Mikey? Little rusty huh? And who else got flashbacks when Peter started removing burners, thought he was gonna get a free Uber ride home 😂
A little rusty
Video is very nice!
Thank you very much!
Always waiting your video
So nice of you
This video are really rocking 💞
Thanks 👍
Strongest HVAC Team in New York. Thanks Gentlemen! 👍🙏
🙌
Thank you for the educational video?
Our pleasure!
Funny that i watch these on days off lol. Good apprentices that take instruction well and also have common sense are pure gold. Before i fully condemn the valves i like to hit the Tc with my small torch to see if theres ANY way it even could work... its more so a curiosity for me at that point. That gas valve got cooked out, likely during yheir basement reno due to dirt.. that damper needs replacing too, its resistance will be high and the failure will happen on the weak part of the low voltage circuit ( looking at you windings for the gas valve solenoid ) . As the amperage ruses against the resisting liad ( like pitted dusty contacts on the damper end switch ) things heat up... till they dont. :)
Thanks for posting your feedback
@@PipeDoctor thanks for making videos :)
excellent job 🤟
Thanks a lot!
Full support 🔥
Yeah?
Always be good video 😎
Appreciate it!
I guess thats why you were so impressed i had a standing pilot, bc you like them. lol. My package will get to you monday, they tried sat but no one was at office. Accept it youll love it.
Very good
So nice
i had to subscribe - Mikey deserves another subscriber - hes great - peter piper too - love the vids! thanks for the knowledge.
Thanks for the sub!
What if the second couple was defective or the pilot was just dirty and not giving enough gas heat to couple or could the Orifice been partially blocked and you could have blowed through it? I was just wondering if you have ever ran into that or even possible? Also want to say I like your name “Mikey pipes”I’m not too keen on your assistance name of “Peter Pan”. You should upgrade him to Peter Piper. I feel that would be a confidence builder for that nice young man.
Professional 👌
Thanks 😅
I give it to you, remember teaching as you are doing a service call your are going to miss things that you would not, when you are alone and observing as you check out job.
Thanku 😊
No thank you
Looking nice
Thank you! Cheers!
I REALLY want Peter to succeed in this field, he's the kind of kid I like getting as an apprentice.Mike you should get a heap of scrap wire of different sizes,so Peter can practice his electrical terminations.
👍
A Lot of people are Guilty of having their Equipment in a Furnace Room and especially if the Basement is Completely Finished. Highly Recommend Air Grills.
Yup 👍
In ca it must be open to attic or crawl space for code
You did the combustion test on my birthday haha
Nothing but hot air
I love the standing pilot I converted most of my electronics furnaces on my buildings with manual standing pilot and for years they still run like a champ I got tired of the electronics going bad at the worst time or the coldest night they always fail now the tenants will never be without heat
Good video you put back the old thermocouple i hope scene it wasnt the issue & you save the customer money .
Nope. It was original. Time to replace
You can test the thermocouple by measuring the millivolts. Unscrew it and use two jumper wires. One goes to the end of the tcouple and the other goes to the copper pilot tube. Relight the pilot and measure the millivolts. Normally gets to 25 to 30. If it doesnt the pilot is bad. Sometimes easier than disassembling everything.
Nothing is impossible 🙌
Correct ✅
The wooden door for the boiler room is fucking hilarious 😂😂 definitely fire department would love it
It's not an issue as look as clearances are meet. The entire room is framed w wood studs
Did you forget about combustion air for a combustion?
@@PipeDoctor not at all doc. You covered it on the video very well. I usually don’t comment on things the doctor already covered. But yea contractor put up walls they never take it into account
Good ♥️
Thanks
Peter seems like a good dude. Give him my number. Looking to hire a new tech.
Ha ha ha
Love that low main vent. Should be up alot higher
It’s actually on the end of a dry return. Yeah yeah I guess a coulle Pio.
We always raised them see the rust and drps on the floor. No more if you raise it. Higher the better.
I also support having the old fashion standing pilot. Much simpler to diagnose. That draft hood sure looks like it was shortened.
The draft hood was definitely cut back
I went back to view the video. It looks like there was a draft damper was installed on the verticle. There is a bracket still mounted just above the hood. Someone replaced the old damper with a new damper on the horizontal. If the damper had been installed where it is now, the hood might not had to be cut@@PipeDoctor
Good job Mike and Pete, The low voltage wires shouldn't be in the conduit or line voltage box service disconnect, NEC code from way back, And they can put vent covers in the drywall, or install a vent from outside for air make up or O2 vent for combustion.
Mikey might want $16,000 dollars to bring the whole heating system up to spec.
It's not the best practice but as long as the insulation meets or exceeds the maximum voltage within the enclosure/ raceway it is allowed by NEC.
If they are dumb enough to pay that price, then good luck, I need to sleep at night, don't need to be tossing and turning in my bed, worried about someone knocking on my door, wanting their money back.
Maybe 🤔
Just leaving a comment on the internet is dangerous enough, some guys go crazy just telling them what to do, they go nuts.
More details where did you to adjust it
the draft hood looks ok to my eyecrometer via video. it says it should be 8" from bottom of hood to top of jacket, but many of them came short from factory, with not enough pipe from the hood to end and didn't allow for the jacket/insulation. I would look in it to be sure it doesn't have an integrated junk bimetallic strip damper that's failing to open anymore.
the powered damper looks very suspect to me, more so when wiggled and hearing the end-switch click, as well as not stopping every 180 degrees. unless they modified them to make a full revolution each cycle to self clean and not stick(none that I know of, but it's possible) 🤔
I’m surprised u didn’t condemn the boiler lmao😂
Not yet!
Just thread and Slide it in Peter....owwwwww😂
lick it first too
@@PipeDoctor 🤣
Sometimes we over look the obvious. I have been guilty of this after so many service calls and go deep then switch it on after awhile.... Sometimes you need to start from scratch at check the vitals.
Is Hartford loop close nipple leaking under pressure. Brown water stain seems very low down, maybe bad gauge glass washers.
I want to move to NY and work for you as an apprentice
Does Peter study your videos on his own time to learn or just at working hrs.
Most young apprentices only want to learn on company time, no extras.
I tested a thermocouple without installing all the way.
1- remove the old thermocouple from gas valve. Just part that goes into gas valve.
2- put new one in, use lighter or candle to heat the new thermocouple, you can try to light pilot , if pilot stays on , then you know that’s the issue and replace the thermocouple.
2 - threa
Yup 👍
Thought you said to get a wire nut. But it must have been get a Wago. 🥴
👍
Love it milivolt tech 101. Very old, but pretty robust 80% safety system. Very inexpensive parts. I remember when electronic igniter s happened. They were so unreliable for years. AND parts were outrageous costly.
Thanks for watching
When I Was Born The Doctor Told My Mother, I Did All I Could But He Pulled Through Anyway.
And you came out halfway decent
Hello Mike, you make mention of it not being OK to mix the high and low voltage in the same J box but it is actually OK. It’s got more to do with the insulation class on the wire. As long as the insulation class meets or exceeds the maximum voltage to be seen in that J box or conduit it is fine, as for example if you were to use THHN on the low voltage in the box with high and low voltage, it would be fine and per code. Also maybe show Peter on how to check DC millivolt for thermocouple troubleshooting.
Okay. Please explain that to the inspector on my next job if I decide to mix voltages.
Mike here is the code to reference National Electric Code Article 300.3 (C) 1. Conductors of different systems when asked.
the thermostat wiring entering/passing through a line voltage box is a violation itself, because it's "class 2 low voltage wiring", which is not rated for, nor ever enter line voltage areas.
yes, even though some has been rated up to 300 volts max, it's still a violation.
it would need a box divider, a separate nipple connected box or the transition splice done outside the jbox, then it would still be an violation at the jbox on boiler.
that's same reason condensers and most equipment have a small compartment just for low voltage wiring to be spliced and then internal wiring is different, where it's allowed to be in close proximity.
also, it may still be against local state, city, town and other codes. they always override national code with greater restrictions, some overrule it by using older code base though.
They definitely can't share a conduit
Hey Mikey, I spend at least an hour to 2 hrs everyday watching your vids😅, I would really appreciate if you can answer or advice my concerns. I have this boiler hydronic system with 2 zone valves since 1987 without any problem like roll out flame,,etc. it’s a Utica gas boiler m6125agbt and doesn’t have draft hood ,no spill and roll out switches. Im learning now all these safety features in your videos. Do I need to make some improvements and install all these now? Thanks in advance
You are perfectly fine. When the system is replaced you new equipment will incorporate those safety controls. I doubt you don’t have a draft diverter. It’s built in.
@@PipeDoctor you’re the man, thank you so much and God blessed
Hey Mikey
👋
I don’t mean to be critical on Peter I just know from the kids I made into union A Mechanics. He looks worth the investment, he needs more hands on to have the confidence. Good job
Hi Mike, why did the roll out switch burn out? It happened to my gas boiler a few times last winter.
Flame roll out
Ok I got to the end, what was the reason she didn't fire right up? Was it the damper or one of the safety switches was still disconnected?
Gas valve. Did you not watch the video??
@@PipeDoctor I watch the whole thing. She didn't fire after the valve change when you hit the er switch. You went back to the damper then cut away
@@randymathews3348 kidding me? I finished the video doing a combustion analysis on the boiler running.
@@PipeDoctor yes you did, even had your little baggie. But why didn't she fire when you hit the switch is what I'm asking Mikey
I know this video is very old but I had the same question. I was expecting it to be a bad flue damper control.
💯💯💯💯💯💯💯
Love ❤️
#2. Thanks for feeding us
You’re welcome 😊
You need to get a covid self test my friend.
You sound like you have a cols coming,that's how i sounded before i popped positive,oh and i think i'm the best plumber😅😅😂
My customers for the most part think i'm the best Plumber. Some think i'm an ass hole but use me anyway. Keep them wrenches turning!
Hello ... Long time
Thanks 👍
Interested about have double 90’s on the pressure relief?
I guess I overlooked that.
pilot flame looks lazy. burners were dirty. gas valve did appear to have been flooded at one time which the manufacturer does recommend replacing if ever flooded. Over all as a teaching video not bad. and every one trains different. i was trained to never leave a unit dirty as it could result in a nuisance call back which can be hard to charge the customer for and could affect your combustion analysis. i do enjoy your video's, in my area we don't have many steam boilers they are mostly hydronic. Keep up the good work at making the trades great again!
Hey Mike, is it code for you to use grip. We don't use it anymore up by us
Grip?
Are wagos a good replacement for wirenuts for 120/240v applications?
Short answer,yes absolutely.
Absolutely
Hey has Peter used the sman yet?
I don’t think so.
Hey Mikey, of Mikey Pipes Plumbing not easy being cheesy. I like your podcast/social media. I guess some of your customers still checking in on you. Hmm, troubleshooting?. I don't know Mikey, but back in the day dealing with most women. I would have been replacing that old rust bucket, for a new rust bucket. Again where is the automatic feed water control? Love you buddy, jolly good show old boy, God save the King.
The automatic feeder is at the supply house. Where it belongs!
I don't know Mikey, our code books here in Washington, D.C. goes back too the 1890's, must be a State of New York thing.@@PipeDoctor
Draft hood looks short.
What was that, barny miller theme song?
👍
You keep the A/C set to 66* at night ? Does the system keep up with that setting easily ?
Yes it does
I just open windows use a commercial fan and home is in low 60s.. ahhhh san jose ca..
Long Sunday video
Thank you for watching
Steve lav is a part’s changing hacker
💥💥💥💥💥💥
Thanks
Mikey
When you set your home air-conditioning to 66 and it's like 59 like last night, will that
shorten life of compressor etc, because I hate when it's humid and 65 outside and I don't put air on cause of above concern
??
TX Mr pipes❤
Nope
get a dehumidifier? it will extract humidity and not cool the home, even heat it somewhat due to natural losses. 😉
A/C is really not meant to be ran with indoor air temp and suffers great efficiency loss.(it can cause coil icing and liquid flood-back which can kill compressor) and for sure not such low outdoor ambient temps(head pressure may be too low) which drops the total system pressure too low and may cause indoor coil icing due to refrigerant temperature being too low.
some heat pump models may be OK depending on design, ideally you'd need an outdoor fan cycle switch, indoor coil temperature/ice sensor to cycle the condenser.
all that said, it may work OK doing so for short periods, but again, get a dehumidifier, seal the home better and make sure bathrooms/kitchens are ventilated to help curb additional indoor humidity. also if you have aquariums, water fountains/features and whatever else indoors, you need to run dehumidifiers anyway.
Low voltage in any state must be seperate from line voltage
Correct. Unless mfg specifies otherwise. Like Burnham.
I didn't see you check for gas pipe leaks
We did
🥳🥳🥳🥳🥳
Thanks 👍
That mushroom vent hood looks awfully low? Some of the power-stealing thermostats caused the vent dampers to go round and round on single zone package boilers. like a steam boiler. I commented on the vent hood before you did ;)
i've never had that happen to me
Around 1980's to 2000 roughly, I would do a new steam boiler, turn it on and the vent damper would go round and round. The issue was the thermostat, change it out or put a relay in and the issue went away. You would see it mostly on the clock thermostats you put the pins in. @@PipeDoctor
Peter will b a great plumber if he stays with u n the future
That’s the plan
🎉🎉🎉🎉🎉🎉
Thanks a lot
You never told us what the actual problem was. Even with the pilot out the vent damper should of opened. Was it the damper?
Did you not watch the video?
I did, after you replaced the gas valve it still didn’t fire up. You started to look at the vent damper and then the video cut to you doing the combustion analysis. I was just curious. Even watched it again
@@williamgildea8348 same thing I seen. Was wondering the same thing.
There is no easy way to determine if the thermocouple is good without replacing it?
Yes, you test them w a meter
Yes, you can test it with a multimeter that can read millivolts but it’s not worth it. It’s not worth wasting the time. It’s a cheap part.

Great video.. brunt boots are junk... Redwing boots the best
Good to know!
🤠🤠🤠🤠🤠
Ty
You probably need the C wire
Yup
Wood door, wood studs and i bet its not fire rated drywall 😂😂..
Hollow door
Before the diverter otherwise you'd be adding outside air to the analysis
Anothe I D 8 error. Fire needs air. Thought that everyone knows that.
Everyone with common sense knows that
Why can't you come to the bronx for a Conversion???
Gas in house?
💞💞💞💞💞
❤️
Also tell Peter mechanics don’t use their phones for a flash light, they use a flash light.
Does Peter carry his own flash light on his person.
We want to meet you 😍
Are you sure?
Nest thermostat junk
Glorified hockey puck.
Mike, If you keep telling him what to do, he will never learn. No more lefty loosey etc etc Let him go He will get it
Yeah, but I’m not gonna waste time on the customers dime
#1 hi mikey
Congratulations
For 35 years we put thermostat wires in the junction box. Manhattan queens Brooklyn bronx long island. Now all jobs were inspected and passed. Now you say you can't anymore but why. Shoot me picture of the code please. Thanks Mikey 😊
Why do people have so much combustible stuff in their boiler room. I see you will be going back there soon to replace that water valve below the gas replacement you just did.
Real estate square footage is expensive
A wire nut!!!!!! Oh lord he’s crossed to the dark side
What about those Wagos lol
42 minutes for a gas valve guess your getting rusty Mikey! Just playing bro teach the new generation the way they should be taught
A little rusty
Peter is easy on the eyes - you...not so much.
Oh well. Can’t win them all
how much money do you earn 🙊
Not enough
Failed all the competitors 💯
Huh
Pilot the water heater should turn on automatically. There is no need to use a lighter.
Wrong
@@PipeDoctor If the water heater pilot is of good quality, it will light the burner with a spark.
