Water leaking from boiler..


More water in the tank, will make the relief water open quicker.

The tank needs to be isolated from the system, then drained of ALL water. then the system reopened to it.

Most likely. The tank was already too full of water. And your rads had air in them. And they were acting as the expansion tank. And after you refilled your system. the water now has no where to expand to.

You can get water directly into solution with no o2 barrier, that is exactly happened to me except it was my hole entire second floor.

One suggestion he might be able to do, rent a pipe freezer and isolate that way. Obviosly turn off the burner and have all the connection made up. Never tried it.

Yes cap the line. The blader could be moved over to the elbow to the right. 3 way t 3/4 npt male 3/4 ball valve then bladder. Isolation is a must because they do go bad. Plus that pipe lookes faily rigid and it would look cleaner there, just my opinion. Don't think depot carries those, heating/plumbing supply store if they will sell it to you. About 40$. You will have to drain you sys tem but no the boiler. While younhave it mt, isolate your rads and t the off so you cann fill the i use boiler valves.

Thanks for the info!!
If it's not to much trouble do you think you can sketch me a diagram?

Also what's killing me is that I totally drained the system, next thing I know it refilled, gauge is past 30 & that pipe is dripping? How is this thing refilling??

If you totally drained the system. Then you have/had the boiler turned off?

The PRV is probably leaking if you totally drained the system, and it refilled.

Pressure Reducing Valve.

If you used the ptv to draon the system you could have sediment on the seat of the valve or it could have erodedthe rubber orings and thats why it is leaking. But that being said you need to replace the exspansion at some time. It is old and less trublesome. In the picture it looks like you replaced a pt already?

First off I would like to thank everyone for helping me on this!!

Is are some better pics & I noticed the connection under the pressure relief valve is split so I'm going to replace that whole connection.

Now this pressure reducing valve, where is that located?

I dont see a prv any where in the pictures. You have a handle valve near the tank tee in to the 3/4 copper. , what is that for. Secondly you should put a back flow preventor in case of city water loss off pressure and you boiler dumping into you drinking water.

Try hanging the tank to the right of wher you want to closer to the radiator riser. At least the that is going up will give it a little more support than directly in the middle of the pipe. Don,t forget to ball every thing you can. Read my earlier post. Hey, good luck.

Here are pictures of stuff. Prv fill valve 1st, second is back flow preventer before prv, and third is where i hung the expansion tank. Notice the rusty china made pipe from home depot/china. Never again. Next time a header.
