GAUGE

nicholas bonham-carter

the pigtail will protect any of the 0-3 psi or 0 to 36 oz. gauges from the ..gaugestore.com. you will be very happy you got one--i have 2--[no. 2 teed on the air vent tapping on a rad upstairs].
don't forget to put it on the same manifold as the vaporstat.--nbc

DOES ANYONE KNOW WHERE TO GET A 3 OR 5 PSI GAUGE? I CAN'T FIND ONE THAT CAN BE USED WITH STEAM.
THE ONE THAT CAME WITH MY NEW BOILER IS A 30PSI. I DON'T THINK IT WILL READ .5 TO 2 PSI ACCURATELY. THE USUAL RULE OF THUMB IS DOUBLE WHAT YOU WANT TO READ WHICH WOULD MAKE THIS GAUGE GOOD FOR THE 15PSI RANGE.

THANKS

The grainger book has a few of the gauges your looking for as do most piping supply houses. Don't forget the pigtail. Grainger can be found on line at grainger.com

The 30 PSI gauge

is just a code requirement, being twice the maximum boiler pressure rating. (Nothing in the code says that it has to be useful!)

I go to McMaster-Carr among other sources. Seek "Low Pressure Gauges". I get the ones that read 0-32 ounces for vapor systems but there are other scales too. Keep looking.

some localities will require a #30 , some of the inspectors are real hard and don't know about steam i have actually had to install 2 gauges on an install just to satisfy the inspector --they want to a gauge double the boilers' rated pressure ----even though its useless to have the 30#
grainger and mcmaster will have what you need -get a brass pigtail too

THANKS FOR ALL YOUR HELP, I FOUND AND ORDERED A 3PSI GAUGE.
IT WILL BE INSTALLED ON A PIGTAILED MANIFOLD ALONG WITH THE VAPORSTAT AND THE 30PSI GAUGE. (MIGHT EVEN PUT A 1/4" BALL VALVE BETWEEN IT TO ISOLATE/PROTECT WHEN I DON'T NEED IT)
