Question. In my area 99% of these plain steel tanks have no airtrol fitting on the bottom. Just a regular bib or gate valve. This makes it time consuming to drain these things down. Would you add the proper fitting or retrofit an extrol style tank? Another question.. every time I drain one I end up with a Pressure reducing valve that doesn't open to fill and then sticks open and I have to valve it off. Would you replace the PRV or leave it valved off?

Ten to twelve videos into it and you pop up, totally awesome video. I'm subscribed.

Dont know if I will get a comment being this video with so old but got a question. We have a tank like this and when I drain it down and open the PRV back up, it instantly feeds the tank. Almost back to the top to make 12PSI for the PRV To quit supplying water. What am I doing wrong? Every cycle ends with a relief valve popping off

[@7islander]

No bladder to go bad, Won't lose the 12lbs of pressure from a leaking Schrader valve. There's something to be said for the old style expansion tank.

Steve's giving it the next level touch!

[@mikel2469]

Does anyone know if that old style drain with the air port is still available and what is it called? I would really appreciate the info. I have a similar tank and it is difficult to drain.

[@worlddomin623]

I just bought a house that has an old expansion tank similar to this, however it only has one threaded hole to connect it to the system with a boiler drain on a tee, no bleeder, no sightglass. When you reopen the valve that isolates the tank from the system, the tank just fills up with water. Does it only partially fill with make up water? How do you stop it from just flooding the tank right after draining it?

[@akakeanu]

Hey did you ever figure out the answer to this? I have the same type of system and am dealing with the same problem

[@worlddomin623]

I decided to just run the system and see if it would pop the relief valve when it reached high limit, and to my surprise, nothing happened 😁 System pressure reached maybe 18psi, even after running for 10+ minutes. Not sure if this will lead to problems down the road, but it has heated my house just fine so far

[@worlddomin623]

I do plan on replacing the whole boiler myself, and I will switch to a bladder tank with an air separator, as well as a magnetic dirt separator to keep some of the iron particles from my system out of my new Weil-Mclain

[@akakeanu]

@@worlddomin623 Wow thanks for the quick response! Just to clarify, did you leave the valve between the expansion tank & system closed? Or if you opened it, did it stop filling up with water eventually? I'm planning on switching to a bladder tank soon as well. But in the meantime I am still stuck with the bladderless one and trying to get the house heated.

[@worlddomin623]

@@akakeanu No, I left it open. Based on how they are supposed to work, theoretically that valve would need to stay open for the water to have a path to the tank to 'expand'. It did stop filling eventually, I'm guessing once the tank was full. I would turn it on and see what happens like I did, my system is an old converted gravity system with lots of large radiators with long runs to the boiler, I have a lot of system capacity for a little 150k BTU boiler. Not a hydronic heating expert, but it could be that based on the large volume of my system, the boiler doesn't have a chance to actually reach 180°F and therefore expand enough for the relief valve to open. I would put a bucket under your relief valve vent to see if your system will expand enough to reach 30psi, and I would also sit there and watch the system heat up and keep an eye on the pressure gauge until you're sure nothing will happen.

The old expansion tanks are the best

Great work steve

[@dennishayes1505]

Mine has no Schrader valve, just a standard drain.

[@adamcoles5463]

Hey Steve I have the same expansion tank on my system, I have a Benjamin cc500 wood/oil boiler. I recently bought this house and new to hot water radiation. I’m having a hard time to heat my house with just wood, the lady that owned the house before said she had antifreeze added to the system. I’m going to drain the system and replace just water, do I need to drain the expansion tank.?

[@jakesmith7457]

will be using tank valve on my installs ,makes draining tank a snap next level

[@michaelcignarella8159]

What do you charge for service calls ?? I’d love to have you diagnose and fix a 1957 American Standard Arcoliner.. High Pressure expansion tank keeps filling with water .. How does one contract your services?? Hanover, MA

The end that was cool

[@BobCairns]

Thx! Worked like a charm!!!!

[@JasonM35]

If it pops the relief valve drain the expansion tank and refill. Got it !

[@stevenlavimoniere]

i did not pop the relief valve???????i try to bypass the feeder to see it was stuck ..and feeding water .never touch the relief valve .if you do you most likely will have trouble with it .

[@More350Power]

That is one old looking boiler !

[@jayman1601]

Do they still make these style expansion tanks?

[@michaelambler2982]

Yay! first comment!...Steve can get some "cardio" in while he waits for the tank to drain.:-D

A Steve,I’m thinking about buying a similar truck like yours,my van is just not cutting it anymore,to small,just wondering how heat and air were in cab?anyway great vids keep them coming

[@stevenlavimoniere]

i like my truck just expensive to maintain parts are crazy money you have to get them from workhorse .i need the truck because of the weight it carries 14,700 gvw and a diesal tween turbo good on fuel 10 to 12 mpg .over all i would not have any other truck for me

[@patricksimone1238]

A Steve thanks for reply,how is heat and air in cab?

[@efrencarrillo1420]

@@stevenlavimoniere how do I refill after draining do I have to keep the water on while draining?

[@sirjohndoeofpa3292]

How often do recommend draining these tanks?

[@jason-ge5nr]

so if the pressure valve pops off it just rains hot water if you are under it? hmm neat!

Well , did you get some reps in while you were waiting ? I could easily do 2 maybe 3 reps ...lol
