I think mine is either rusted, or clogged but I can't get any water past the valve. 24 volt are at the head and it energizes an slidde all the way into manual but nothing. Almost impossible to find info on this.
That's exactly why I replaced mine. Did a lot of troubleshooting with the thermostat. Once I figured out that the thermostat worked and the wiring was okay, then the only thing left was that the valve was stuck in closed position.
@@mvdieterle I really appreciate you taking the time to do this. Replacing mine the day after tomorrow since my buddy said he do it for some beer. Just gotta survive single degree temps tonight and tomorrow. lol Thank you again.
i believe i have a valve stuck open. Can the seat be replaced without draining the boiler. this sounds like a stupid question, but the instructions made it sound like it was possible, as long as you installed the head vertically.
Hi Mydieterle. I have Mc Lain boiler heater two zones with two thermostats. One Taco zone valve got stuck. Now I don’t like two zones separate anymore. Can I get the Taco valves out and connect a thermostat wire to Mc Lain furnace for it works directly to all heater pipes in the house? Please let me know. Thank you.
Hi Sonny, I am not a technician. But in principle, of course. The zone valves allow you to control the two loops independently. If you want to heat the whole house all the time, then you don't have to connect the zone valves. It might be cheaper just to replace the stuck valve, however, and leave it it open instead of getting both removed. One thing to consider is that if you only use one thermostat, then the temperature in the other part of the house (2nd zone) will be at the mercy of the main zone. For instance downstairs would not get quite warm enough. If it's upstairs, it might get too warm compared to the first floor. Good luck!
@@mvdieterle Thank you so much for your reply. A friend of my told me to do that, but I’m still confusing. Now with the advice from you, I know which way is good for my case. . Thanks again and have a great night.
Yes, you can turn off the valve if it was manually pushed in. Note that a heating zone usually controls a whole floor or section depending on the size of your house. Also, the manual lever is just a backup if your thermostat doesn't call for heat. If your system works correctly, then you wouldn't be able to "override" a valve that is already open.
@@mvdieterle I guess what I’m really going after is turning off steam to a certain room in the house while keeping others active. There’s no sub thermostat on each room’s floor radiator. Not sure how to pinpoint downstairs
How to remove valve from housing? Assume new comes out easy? Have a spare I cant get out so may buy a new one as part as expensive as whole valve. When started to remove plate on one installed the valve popped out/closed so that along with seating know needs replaced. Installed shutoff valves above and below for this reason but getting valve seat out....idk. May have to destroy one installed that is stickung to remove and hope dont damage housing. Figure some sort of puller.... PITA.
Hi Andrew, sorry you're having trouble with yours. Yes, a new one literally pops out due to the spring that closes the valve by default. Mine was stuck, too, and it took quite some effort to remove. I sprayed WD40 on it and let it soak in.
Thank you for making the video. Having said that, i wish your camera skills were better. The camera is on subject less than 50% of the time. Can’t watch a video if what i’m trying to see is out of frame.
Thanks for the comment. You're absolutely right. I should probably use a tripod to have better framing. Shooting on your phone and handling the valve with one hand is not easy :D
I believe you are misinformed as it is not the little arm that moves the valve into the open position but the plunger in the head that is moved by the wax heating up and expanding unless you need to do this manually.
Thank you, I have been looking for this info for hours!
same! But days!
Finally found the info :)
Finally. The first real explanation. Ty

Is that side lever also to turn off one valve so one room does not get heat? I’m trying to figure out what I can do
Yes, you can turn off the valve if it was manually pushed in. Note that a heating zone usually controls a whole floor or section depending on the size of your house.

@@kaltrex9465 don't you have a hand valve at each radiator?
@@mvdieterle not in the rooms. It’s the old long floor panel kind, not a vertical radiator with a dial

It has to be “sweated “ out, ie heated and then removed. Not easy
When is the lever used?
Hello Dave, the lever is used to manually open the valve if you cannot control the zone from the thermostat for some reason.
Hey Great Video, really appreciate it, you are 100 % correct, could not find a Video of these either…..
Very helpful, thank you!
Very very important video. Thank you for sharing. Just your camera was off of the subject.
Thanks! Jon Voight
Thanks only video showing the base great job
Thank you!

That little are on the side would not touch the center of the valve that needs to be pushed down manually. The little area forces the plunger down
