The Watts 2000 boiler flow regulator

[@DieselLoco]

Thanks for that excellent video and taking the mystery out of how these valves work. The cutaway of the valve was fantastic.

Welcome GFM

I work for the air force now but all through college I watched you're video's. Excellent channel!

[@grayfurnaceman]

Thanks for the support. GFM

[@dsfgnk4]

Thanks. Wonderful, very-clear, fully detailed presentation, which took the mystery of this valve. Now I know how to set it for my system.

[@craignehring]

I grew up with a coal fired boiler, then changed out to a gas one, never saw one of these though. The system may have had one, I remember the pump though, it was a Bell & Gossett. I was always amazed how quiet that pump was. Thanks for this video

[@twintwitch1]

Thanks, great service to us all who take care of our hot water boiler ourselves

[@gephrobodine]

Very informative, thanks. I was looking at the literature for my BG SA-1 valves and it didn't explain much. I found some valves open, some closed (forced system, 3 zone). There's been a lot of hands on this before me

I'm making a waste oil burner my garage gets cold and i work on engines and i take the waste oil and i save it for my oil burner and your videos have helped me alot on ideas and how the oil burners work. I just wanted to say thank you

Welcome GFM

[@moongloomable]

Perfect video thank you

[@hvac1238]

Still a ton of these and B&G/Taco versions in my area, have them seize up all the time. These older "controls" are hard to explain to guys over the phone. The filtrol systems and 1311 W/R zone valves are always fun also. Good video thanks

Growing up with a coal fired gravity feed boiler in our house , there was one on our boiler. Going on to work in the plumbing and heating trades I soon found out that the correct term and what they are sold as is " flo - control" , most of the ones I encountered back in the early 60 s were B&G. Even after my parents had the coal boiler converted to oil the flo - control was left on. Say what you want about coal heat but your house was never cold. Seventy five now and I would go back in a heartbeat.

[@grayfurnaceman]

I also grew up with a coal boiler. 6 tons a year. The problem is not so much warm, all fuels will keep you warm. Its efficiency. The low fire is essentially wasted fuel. We cannot afford this anymore. GFM

[@mrkrasker9609]

Could you give a talk about venture/mono-flow tees?

[@throttlebottle5906]

that would make a good video :)

[@tnguyen1421]

Thank you! Very informative!

Nice work

[@southoldfarmhouse2490]

Gray, this video is great! Quick question - Should the top screw be turned up or down when trying to purge the system of air? I have two of these flow control valves on 2 separate zones ... One of these valves seems does not close correctly, or is stuck open so I end up getting "runaway heat" in that zone when the heat in the other zone is on. I would like to try purging the system of air (I have a steel expansion tank) and was wondering how the top screw should be adjusted when trying to purge the system ...

[@grayfurnaceman]

All the way up will let any air pass, even when the system is off. They sometimes do get stuck open. GFM

[@xJMSports]

I have a 4 zone system with 4 of these (one on top of each circulator). I have a zone that constantly gets heat while other zones are on. The zone that gets the heat has the knob turned all the way in, and appears to be leaking from the knob threads. All the other zones work as expected. Ive kept the thermostat in that zone at 60 and on a 30 degree day that area of the house which is seperate from the rest was 69 degrees. All the other zones have that top knob a few turns from bottomed out.

[@educatedrock]

its being back fed, you probably have a bad circulator. Check your returns and see if its hot.

[@allenluberger1511]

My valve rattles once in awhile. have a one loop system and bleed alot of air out the other day. thought that would stop the rattle. seemed good. now heard rattle again. how do i adjust valve thumb wheel. any count of turns?? i did replace valve couple years back. maybe i just need to make a simple adjustment. Thanks in advance for your help.

[@cdm9011]

I just bought a house this summer, and we just turned our boiler back on once we filled the tanks. I have a B&G version of this valve. When the boiler turned on we noticed the radiators were getting hot even though heat was off. I went down and noticed this valve was opened, and then turned it all the way down. But now when the heat is being called for and the pump is running, the radiators are not getting hot. So it seems like this isn’t opening like it should. Is this a common issue, where they get stuck closed? Or is a bad pump more likely? Should I back it off a little bit? Or should I just replace the valve?

[@grayfurnaceman]

You can try backing it off but the valve may need to be replaced. GFM

[@totjason]

You are amazing

[@mikemike9844]

Hello, Im watching your videos and find it real good and more than. Thanks a lot for passing the knowledge. Although I'm from St. Petersburg (Russia) and it's kinda hard to get into (as we use kg, Celcius, metrs). Anyway, in the video about zone valve, you mentioned about making a video about water hammer; and, as I could guess, it wasn't released. So, could you post video about a water hammer ?

[@volvo09]

Thank you!

Thanks for the cross section view!

Merry Christmas GFM

[@throttlebottle5906]

silly item of the far past, but still nice to "know what they do and are there for!"

[@snoopdogie187]

They are still used. Where I am now is still on steam heat, which is even further in the past.

[@johnkrim8377]

I don't know about silly item ,but with proper maintenance it did its job. What would you use non electric to do the same job at the same cost?

[@rogerrolfe8114]

Silly item a heating/plumbing tech should know about as lots are still used and sold. People who don't know usually screw up a system by turning things with out knowing their function. Some don't realize that if your hydronic system rises above the boiler and you need to drain the whole system for service or repairs you need to turn the stem up to open the valve. If not done the silly person will cut into a pipe full of black water as if left closed the water will check above the valve. Another reason to open (turn stem up) is to gravity feed a system where maybe the only 1 circ pump has failed and you want to give some heat to the building. Not every service vehicle has a pump to replace the one on site or their backed up with to many calls on a cold night. Every service person has been the silly person when in the learning curve, we're always learning so don't be afraid to take advice or good information.

[@RealityRenovations]

What causes them to rattle?

[@grayfurnaceman]

The plunger is loose inside the part. So the flow of water thru the part, especially if there is air entrained, could move the plunger. Bleeding air from the system may help or adjustment of regulator thumbscrew may help. GFM

[@TheNYgolfer]

Didn't realize how much that valve restricts the flow

[@caru3257]

I had to tap on a B&G to loose it from an air lock.

[@grayfurnaceman]

Not especially unusual. GFM
