skim port?

Brad White_201

I am always pleased when I find a skim tapping, sometimes a full 3-inch bung, most often a 2-incher.

Skimming removes films of oil, casting oil, sealant oil and other water-borne impurities. Solids will not benefit from skimming and will reside at the bottom.

The leaking returns you have would not be helped by skimming in my estimation.

A chicken and egg scenario, but I suspect it starts with the leak which begets more raw water which accelerates corrosion, etc. ad terminum.

I am on a return leak job (steamer) and this peerless sectional boiler does not appear to have a port for skimming. Where are they typically on there? Could this be why there was soo much dirt in the return? It was buckeling the floor under the leak and showed as a huge hot spot with the thermal camera...

Thanks,

Tim

Thanks for the reply. I have fixed the return & flushed out the boiler very well, as well as blown down the LWCO, but I wanted to skim when totally done tomorrow. There is just no tap, unless they did not cut an access through the jacket. There is only one 1/2" plug behind the LWCO probe body which is not accessable.

skimming a peerless

looks like my 211-a except that the instructions call for a "t" [instead of the elbow i see in the picture] on the steam main exit pipe so that you can have a skim port.
if there is no elbow on the other end maybe a plug or if you are lucky a nipple and cap which could be the new skim port!--nbc
