Customer Questions & Answers

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.

Can this be used on a boiler with an indirect hot water heater

Asked by: paul
i would not use this product if it will get into the potable water system because this is not NSF listed for potable water. This would be acceptable to be used in a self contained Boiler system and be sure to follow our instructions which can be found at www.oatey.com (part #30115).

I do not see any opening in safety bulb?

Do I have to take it off to put this?
Asked by: John
You would introduce this product through a safety valve opening. I would check with your Boiler manufacturer to locate that. We wouldn't know about your specific Boiler.

Rated 5 out of 5 by from Works as advertised! A week before heading out on vacation I discovered a leak in a pipe joint on my boiler. Not having enough time to get a plumber in to repair the problem I tried some plumbers putty and other temporary sealants to resolve the issue. Each of these seemed to slow the leak down, but did not completely stop the problem. With just a couple of days left I decided to give this product a try. I followed the instructions unscrewing the pressure releif valve and pouring the product into the boiler. After reinstalling the releif valve I fired up the boiler. I was stunned to see the leak completely stop within minutes. I held my breath as the boiler pressure rose as this is when the other products failed. No sign of the leak reappeared. I checked the boiler over the next two days and was happy to see that the boiler remained dry and the water level in the boiler remained intact. This is a wonderful product!
