Boiler Seal

My contractor (a realative no doubt) put a quart of stuff called boiler seal into my system. I guess he was hoping it would cure a pinhole leak in the custom welded fitting that connected the new system to the old pipes (it still leakes). Will this damage my pipes? It said to mix it 50-1, so it is super diluted since my system holds a ton of water.

    fix it the right way

    honestly I do not like fixes like that, spendf the time and fix it the right way, thats a bandaid on a wound tha tneeds stitches. It will not damage your pipes since its designed to be in your system, but age of pipes is a factor. what custom welded fitting is this? you mean a soldered joint? take a picture if you can and post it here. best bet, drain the boiler, fix the problem and refill, get all that stuff out and fix it the right way, maybe do not let your relative do it. Nothing personal

    Thanks for the tip. I definately plan to get it fixed right. I also plan to get someone with a bit more skill at the fittings. I'm just torm between a refill right away for the seal goop, then another refill in a week or so once I get the piece made properly. I have a Spirotherm, which should help. However, they insist there is no way to estimate how long it takes their product to remove the air. If it is days, then I should just wait and get all my ducks in a row. If it is months, then a few intermediate fills, each targeted at a specific problem, would work well.

    I wanted to run it a bit before summer, but also need to make sure I have heat, since the whole house is a single-pipe zone. It is a pickle.

    The problem with the weld is that we bought a 5-inch threaded reducer, but couldn't get the 5 inch threads to break loose, even with a monster torch and a 4 foot wrench. So we had a local guy weld a 2-inch female threaded adaptor to a steel plate, but his weld didn't hold. It really didn't matter anyhow in the big picture, since the wrenching on the old pipes caused a new leak.

    Can anyone give me an estimate on how long a spirotherm woudl take to remove the air from around 130 cubic feet of water?

    There's no way to know,

    but this is fact:

    1) The hotter the water - the faster the air will be removed.

    2) The entire system should be power bled first. Unless the circulator is huge, flow in the areas where air "hides" will not flow past the vent - but rather "linger" in the top of the system where flow will be minimal or non-existent.

    3) The spirovent can only eliminate air that passes through it.

    4) The time it takes for all the air to get snagged by the vent cannot be estimated, but if you first eliminated all visual air and then ran the system at 160°+ for an hour, I suspect 99.9% of all "entraned" air might be caught by the spirovent. The problem then would be the remaining .1%

    Thanks for the tip Ken. I have a pretty good system for filling - at least from a trapped air standpoint. Its work, but its efefctive. Chris
