The debate on this issue will live forever as long as men have and express their opinions. Some will agree with gaskets and some will think only steel puch nipples will ever work and last.
I've been in the business for over 40 years and have installed many Smith and Weil Boilers. Only recently did we have a gasket problem that required changing the boiler. It was due to IMPROPER installation and POOR maintenance. I personnally, have never had a gasketed boiler fail and will always use them. I'm a big fan of Weil-McLain steam boilers and it's the only one I'll install on a steam system....
We had to add a section to a steam boiler recently when an additon was built. We dismantled the boiler, added a section, and a new jacket in 2 1/2 hours. This probably would have taken most of the day with a steel nipple boiler. (It was a WEIL). That's my opinion!

    Cast Iron Sectional Boilers

    Cast Iron Sectional Boilers

    I am looking at a boiler replacement for a one pipe steam system (low pressure 1 ½ lbs steam). The existing boiler was an HB Smith only about 18 years old. Due to many reason's – all of them not the old boilers fault, it was badly used and now needs to be replaced. The existing boiler was a gasketed type. I am looking at a new Burnham or Weil-McClain sectional boiler for the replacement. The Burnham is the push nipple style (no-gasket) and the Weil-McClain is a gasketed style. Any comments on which is preferable? Both are available – just looking for pro's and con's on either style.

    Thank you,

    Toni

    I have always preferred

    push-nipples to gaskets. That said, Weil-McLains seem to hold up well, even though they use gaskets.

    I vote for push nipple boiler

    over the years I have seen too many W/M 368 series boilers die a slow death. There gold series hasn't been around long enough to know for sure they will last. That said the Burnham is a heavy cast boiler, they too had problems with the V-7 series , so now it's a V-8 and so far I haven't had any problems with boiler, but my back! cause they are heavy. I really like the fact that both boiler and nipples will expand and contract at the same rate due to same metels,come to think about it I have never seen one leak due to nipple failure only casting failure which they will replace,but so far the V-8 has proved to me too be a good boiler. Yes, I'm a Burnham dealer. John@Reliable

    aging well

    Thanks for the compliment John, but I got an early start. Will be 55 this fall and am a forth generation P&H guy. We have 30 licensed master plumbers and quite a few oil guys in the family tree over four generations. Started summers and weekends/vacations as a boiler brush and go-fer when I was 9 or 10,and have been at it ever since. Maybe someday I'll learn that there's got to be an easier way to make a living (on the old body anyway).
