Where do u put it in?

Asked by: Miikeyd
You put it in the boiler. You shouldnt attempt this if your not qualified you cold get seriously injured. 1st you need to turn the power off to your boiler. 2nd very important you need to drain the pressure off of your boiler if you dont do this you could be seriously scalded. To do this you need to shut off your your incoming water feed to the boiler 1st. Then I would shut off any valves to any zones. Open boiler drain (hopefully this is a good drain thats not going to leak after you re-fill boiler). Remove boiler relief valve. Pour in the proper amount of boiler seal. Re-install relief valve ( I would re-place it with a new one myself) re- fill boiler. Note when you drained boiler you should only drain enough to bring pressure to 0. Re-start boiler and open all valves that you had closed.

My 25 yr old boiler developed a leak into the firebox, bad enough so that the water leaked out of the secondary air shutter. Happened in the middle of heating season for the Northeast, couldn't be a worst time of year. Being faced with an inflated replacement bill due to the season I needed a miracle to make it to spring. I was skeptical but saw the positive reviews and felt this was worth a try to buy 2 more months. It is an understatement to say that I am amazed at how fast this worked. I siphoned out most of the water, drained the tank and added this as per instructions. Ran the boiler at 170 degrees and circulator on. After checking the fire box 2 hours later, all signs of water are gone! The external moisture dried up within hours and I've been checking it constantly. I truly hope that this will last until spring... I am pleasantly surprised at the results!

I was skeptical but within an hour of putting this into my outdoor wood boiler, the leaks were all stopped, including one big leak that was coming from the main tank and leaking into the firebox. That was about a month ago and all is well. I highly recommend this product!

Now, 2 months later, it is not leaking. It seems to have helped the whole steam furnace; it heats up faster. Great product for my issue.
