relief valve/skimming port/additives

Burnham Independence IN5 . . . I decided to do the relief valve / skim viewport / and additive port in one fitting. The discharge pipe usually lives on the relief valve. The picture is probably self explanatory. I just don't know if there are any problems or cautions with this setup. And this is pretty much the only place that would know :-)

    you can use the 1" skim tapping on the right side of the boiler using standard practices.

    good idea

    Thank you. The installer did not add a skimming port. I had seen them reconfigure the "Safety relief Valve" port to do that.

    I've done a little more manual reading and now find there is a 1 inch factory plug in the "Surface Blow-Off" tapping. It is a little lower than the safety valve tapping. Sure wish those folks had done this properly. This might also be a better tapping (larger) to use for things like a Steamaster tablet. But nothing is happening over the holiday. Because we know that on holidays nothing can go wrong go wrong go wrong go wrong :-p

    Definitely better.

    Apart from the larger size, it's also at the right level. If you use the relief valve port you always need to lower the water level when you're done.

    But don't neglect the relief valve port. You should test your relief valve at least once a year and make sure it doesn't fill up with sludge.
