Dirty Steamers!

James, suggest you start a new thread with this question. Not sure why it is in this thread.

How dirty of a steam system have you guys seen?

How many times did you have to skim it until the system settled down?

We have a bear of a system we've been messing with. We installed it last year and it runs great for a few days, very quite. Then one day Bam, bang, clank. Clean her out and she's quite again.

I did find a bunch of galvanized piping in an attic knee wall yesterday and replaced it then insulated it. The piping was trashed inside, actually one radiator was not working because of it. I think this maybe the cause of our problem but I am not sure.

we just had one that

we skimmed probably eight times..finally we conceded to TSP and then drained and refilled and skimmed..then a couple days later it did it again..we flushed out the return pipes, drained the boiler, reskimmed..been fine since..but it was our dirtiest yet..was a good thing we put flushing connections on the return piping.

skimming

The worst ever for me was a large residential boiler we installed. When the old boiler was demo'd it looked like chili oozing out of the bottom ports.

Had a least 24 hours of skimming, boiling and dumping to get the system to behave.

This job had isolation valves on the wet returns as well.

That has to be the dirtiest system I ever saw

If you can set up a recirculating system to flush the piping out with, using a TSP or MEX solution, that may help. My partner has a power-purging setup that he built using a 20-gallon trash can as the reservoir, a similar setup might work there. Flush all the piping and radiators from the top of the house down to the basement with the solution. I bet you loosen enough dirt to make a big mess :-O

Vaporstat installation

I just installed a Honeywell L408A Vaporstat 2 days ago and it has a pendulum on it for leveling side to side which I went by. It does not have a level for front to back. Is that adjustment critical also? It worked OK till this morning and now it is turning on and off every 45 seconds. It is still level by the pendulum. I also put a small bubble gauge I use for leveling clocks on the top of it and it shows the gauge is level side to side. I have the main at 8oz and the diff. at 8oz.
