This stuff worked great
Have a 20 year old boiler. Limping along till I get my newer one installed in spring. All of a sudden losing a few gallon a day. I put two quarts of this in an 80 gallon open system wood boiler. Within a day leak is sealed. Haven’t had to add water for a few weeks now. Well worth it. I did not mix to a 50:1 ratio like recommended. But still did its job.

It works
Product does what it says! Mahoning 300 small leak adding 5-7 gallons every couple days. Put one quart in of Black swan in and a few hours later no leak! It has now been a week and still no signs of a leak. Would have gave 5 stars but bottle leaked in packaging making a mess.

It works
I have wood boiler that holds 300 gallons, and had a pretty bad leak. I put 2 quarts of Black Swan in, and it almost completely sealed it. Now just a random drip every once in a while.

SO FAR, SO GOOD!
Had a water leak inside my Peerless oil furnace that was causing low water levels and white smoke from my chimney. Ordered this on the recommendation of the service tech from the oil company. I added one bottle and now I have normal water levels and no more white smoke! This stuff is amazing!!

THIS PRODUCT WORKS
I have a Hardy (H5) since 1993. IT WAS LEAKING BETWEEN 5-7 GALLONS OF WATER EVERY 3 DAYS. IT HAS 130 GALLON CAPACITY, I WAS UNSURE HOW MUCH TO PURCHASE, SETTLED ON 4 QUARTS. IT ARRIVED DEC. 3, 2021 AND I PUT 1 QT. DIRECTLY INTO THE TOPPED OFF WATER TANK THAT WAS AT 180F. WITHIN HOURS IT STOPPED LEAKING COMPLETELY. AS OF TODAY 12/30/2021 IT HAS NOT LEAKED A DROP. THIS IS A PRODUCT THAT DOES WHAT IT SAYS IT WILL DO.
