Hi Steve, I am a retired HVAC-R oil & gas burner service mechanic, pneumatic controls, centrifugal chillers service mechanic after 47 years. I have been retired for 8 years. I enjoy your videos very much. Brings back the good old days. In watching the videos I was curious why you don't use the rotation tester and A C indicator, that you use on solenoid valves to see if there are energized, to check if the grundfos or taco circulators are running. Just hold it to the center back of the motor and it will rotate in the same direction as the motor. Keep up the good videos.
Be careful guys. I just tried this easy method of installing this pump and it failed miserably. It leaked like hell. He does warn us about this possibility. As it turns out the newer pump housings are machined for an Oring, but the old housing is machined for a quad ring, and the supplied new Oring does not fit the old quad ring grove properly. Close but no cigar. Tried several times to use new Oring, and the old quad ring but all attempts leaked. Bit the bullet and reassembled the new pump back to the new pump housing, and took out the complete old unit, put in the complete new unit and everything was just perfect.. No leaks and fired up perfect. This is a fast easy method if both the old and new pumps are close in age where it is likely there are no design changes.
Great video steven lavimoniere I was at a job yesterday to change a pump and tried that trick. The homeowner was watching and he made me change the whole assembly lol. "Better to change everything " he said, " this way it's all new and I won't have any problems"
Same thing here. The pump burned during a power spike ( electrician that wired the thing didn´t put the right breaker) after a power outage. The housing and gaskets were perfect. The customer just didn´t want the old one.
Hold on there paying for a pump replacement, which means installing new Flanders gaskets as well. So now if it leaks from the flange gasket , it's another that could have taken care of at this job. That's kind of messed up brother, just cause You want to save time ...this is a job I have to say , you should have done the right thing and swapped out the whole unit that was paid for ..I wouldn't let you get away with that...! I enjoy your videos but when your wrong your wrong..
Plus, the right way is probably faster than this. Why go through all that trouble when you can just swap out the whole thing? No way this is faster than changing the flanges. Plus, you probably void any warranty by swapping new into old. It's going to fail again soon. Why eat the cost?
How much you charge travel time 1 hr 20 minutes to North of WORCESTER? Need to replace one of these, plus a valve on the pipe feeding it, plus install some shut off valves on cold water / hot water pipes, plus solve water hammer problem
I have three heating zones, and one pump needs replacing. All of the circulating pumps are installed above the level of the boiler. Is it necessary to drain the entire system, or can I just isolate the affected zone, drain only that zone and purge only that zone after replacing the pump?
I have a bad taco 007-f3, will a new pump motor (007) bolt in like you did in this video? Are they universal fit to the cast iron part? Thanks, great vid
hey steven i have a raypak water heater at work can you help me please. My work asked me to lubricate the motor & pump bearings where would that be located?
I HAD four Bell & Gossett(?) circulators. I was away hunting when the wife called to say the heat wasn't working. I said call "the" plumber and she called "A" plumber. Well when I got back and reviewed the bill the jerk had replaced all four circulators to Tacos and charged me $380 EACH!! He also replaced the 4 zone control thingy with a Taco as well and charged me $400 for that. He billed me for two guys for 8 hours ($150.00 X 8). I also got 2 check valves changed out which were the only ones he could get to easily. I went on line with Cheapo Depot and his cost for the circulators was $100.00 each as was the zone control. They left all the trash behind but took the old copper heavy circulators with them. The bill was just over $3500.00. I suggested he had a better chance of seeing God if he thought I was going to pay him a nickel. I figured he deserved nothing for trying to screw me over as badly as he did. Is a 400% markup on a $100.00 item considered gouging. My usual guy said he thought I got screwed without getting kissed first. What do you think?
Thanks for the video Steve! My supply house told me a quiet pump was still working, but it turns out it was performing on its last legs. Signs I should have paid more attention to that easily showed my simple one zone system had a bad circulator pump: radiators one branch were really warm, while others on other branch were very cold, I had about a 50/50 split, interesting not upper units vs lower, just one branch vs the other branch-within that one branch the 2nd floor radiators were much hotter, that I could not shut valves at the unit and control the heat (heat was coming through return also, and more recently my boiler was rapidly cycling on before shutting off at the upper temperature limit and the pressure kept climbing way up and the release valve was whistling like a barber shop quartet during firing, then both temp and pressure would fall rapidly. Thanks for the help, was a really easy fix, no need to change housing out either good pointer there. I was quoted $815 to do the work, but given I had the tools and knowledge of how to hook up and restart a system it was a matter of the pumps cost and my time. Keep posting!
Your pipes are hot because your 2nd floor return is near the 1st floor return. Steel is a good conductor. I have the same problem as you. Sure you fixed it now but I bet it was the taco recirculator pump like the one he's replacing in the video.
The old pump looked beat up. Why not replace the whole pump? the old O rings between the inlet and outlet of the pump might be in bad shape. It is a good time to change the whole pump since you are draining the system. These are the corner cutting that contractors do.
Good work steve! Sometimes things like to act up when were not there and work fine when we are there its a pain but it happens to us all! What do you think about weather responsive controls steve? Ever put any on? Like em, hate em?
awsom70 i am not a fan of outside reset controls on a older system like this one .on the newer condensating boilers yes,, depends on the system there hooked up to .
I have now power to the Honeywell Aqua Stat and then power stops at that point. The emergency on/off switch being 60 years old was shot and arc's. The Taco C-P is not picking up current, as when listening, there is a Hum while on standby. What ever happened this Repco broke down i in series of 3's. 1st the on/off switch. 2nd the Thermo-coupler and 3rd the C-P. I will have tackle the CP on my own was i trouble shot the other two. And now as i see these new Taco's C-P's, they are with out a Capacitor as the old C-P's have being 27 years old.
FYI, if one radiator is not working and you let the room out and they decided no to pay rent, check the on/off valve even if you think the valve is frozen.
There are 2 things wrong with this video: 1: You didnt show us what was wrong with the old unit. What exactly was wrong???? 2: Why didnt you just change the cartridge instead of the whole circulator???
because i can buy the whole cerculator for the same price as just the cartridge... why would i buy just the cartridge ?? from your comment i can tell your not in the trade
Thanks for posting this video, I'm diagnosing my own heating system and the taco pump to my upstairs will burn your hand if you touch it but the pipes its supposed to circulate are barely luke warm. Tells me the pump is busted. Your video helped me confirm my guess, especially with this comment!

Hey Leroy I have a few old school plumbing and heating questions if you would like to chat..house built 1956
Thanks in advance! ~CT
Appreciate the suggestions... Simply put!
Thx! I’m buying one now.

Thanks for your helpful advice... Much appreciated
Good Job Steve, Makes the job tough when things are intermittent.
Arnie Grote yes i agree but this time i was there it was not working.so i could pin point the problem easy
Great video steven lavimoniere I was at a job yesterday to change a pump and tried that trick. The homeowner was watching and he made me change the whole assembly lol. "Better to change everything " he said, " this way it's all new and I won't have any problems"
JP Raimundo well the housing and gaskets on the older pump were fine .if they were iffy i would have changed out the whole pump.
Same thing here. The pump burned during a power spike ( electrician that wired the thing didn´t put the right breaker) after a power outage. The housing and gaskets were perfect. The customer just didn´t want the old one.
Hold on there paying for a pump replacement, which means installing new Flanders gaskets as well. So now if it leaks from the flange gasket , it's another that could have taken care of at this job. That's kind of messed up brother, just cause You want to save time ...this is a job I have to say , you should have done the right thing and swapped out the whole unit that was paid for ..I wouldn't let you get away with that...!

Well, this is his strategy, keep the flander gasket and come back next time for another $100. Keep him well and a live

Thankyou, what a pro,u didn't waste one movement.
Steve,
Thanks for posting another great video. it looks like you got a new transfer pump.
Jonathan Smith a small one i like to use on waterheaters .
Good job Steve. I do the same , I just replace the motor. unless I have to replace the entire assembly.
Emin HVAC a small trick to show the young guys
now that was some serious work going down right there,,, great job steven, great job,
letseeitplease thanks for the comment @ for watching
I have air scoop installed in my system. Would it take care of purging the air or I would have attach the house and bleed it like you did?
My second floor don't get hot only for a little bit. Pump shuts down too fast after boiler cuts off. I think I need a bigger Pump
You were right Steven about that system "Having Several Issues!" It was a nice 55 degrees today. You can see the snow melting before your eyes!
Brad1237202 its melting slow but sure
can you take apart the taco to check the inside without causing damage?
How do u purge wo a purge station?
I have a bad taco 007-f3, will a new pump motor (007) bolt in like you did in this video? Are they universal fit to the cast iron part? Thanks, great vid
hay steven what do you do when you see that the basement still have expedites down their or on the pipes.
Is the O-ring for the cartridge installed Dry or did you lubricate it first?
hey steven i have a raypak water heater at work can you help me please. My work asked me to lubricate the motor & pump bearings where would that be located?
Find them yet 🤣
Where are the isolation valves?

You were charged basically double what you should have been if not more than
Thanks for sharing Steve.

Similar issues I appreciate your comment
With the tools and know-how.... Exactly!
Now with the warmer weather the no heats are coming in like crazy!
Truckguy900 Truckguy900 work is a good thing
Nice work Steve , snow is melting and had a few flooded basements today . How's it by u ?

london johnson what's up ?
Another great job and video Steve keep them coming !!!!!
Harry Dickson i will try
my pipes are hot but the downstairs is cold and the upstairs is normal, what could be the issue?
+Dawn n i would have to be there to see whats going on ,
Your pipes are hot because your 2nd floor return is near the 1st floor return. Steel is a good conductor. I have the same problem as you. Sure you fixed it now but I bet it was the taco recirculator pump like the one he's replacing in the video.

Nice work Steve.
Nice job Steve
Jorge Mejia thanks for commenting
Why no air eliminator? Shouldn't there be one? The air in the new water will be less soluble as it is heated and come out of solution.
Michael Licitra a lot of system i work on do not have and air scoop purge it well and you will be fine .
steven my boiler comes on, but heat not circulating even if i manually open the Taco valves... pump is not making any noises...
what are your thoughts
Mine too Steve!
REBELS PROPHET turned out to be the circulator pump
I have now power to the Honeywell Aqua Stat and then power stops at that point. The emergency on/off switch being 60 years old was shot and arc's. The Taco C-P is not picking up current, as when listening, there is a Hum while on standby.

Nicely Done 👍🏽
Isn’t that cheating? i mean not changing the entire housing with the 2 gaskets?
I thought you would change the whole part because of the warranties
+James Splint i do what i have to to get her fixed
when i changed my pump , i took is off without draining, just did it fast. lost a quart of water. it was fast.
I might try that. Need to replace a pump
Good video enjoyed it.
bear maintenance thanks for the support
FYI, if one radiator is not working and you let the room out and they decided no to pay rent, check the on/off valve even if you think the valve is frozen.
Why would this plumber not replace the whole unit unless it’s not a paying customer. I didn’t watch the whole thing?
well done ! steve
+Leonardo RamireZ007 thanks for watching& commenting
Why would you buy a whole circulator ? Just replace the cartridge?!?!?!~?!?
Where can i purchase a cartridge for a Taco C-P?
Tube and Knob wiring from 1930's
Justin Vancouver not quite that old ..but old enough
Thanx for video.
nice work
You are draining the system why not replace the entire pump..
There are 2 things wrong with this video:
1: You didnt show us what was wrong with the old unit. What exactly was wrong????
2: Why didnt you just change the cartridge instead of the whole circulator???
because i can buy the whole cerculator for the same price as just the cartridge... why would i buy just the cartridge ?? from your comment i can tell your not in the trade
J ,
Thanks for posting this video, I'm diagnosing my own heating system and the taco pump to my upstairs will burn your hand if you touch it but the pipes its supposed to circulate are barely luke warm. Tells me the pump is busted. Your video helped me confirm my guess, especially with this comment!
