tridicator gauges

I just wanted to let everyone know that you can still purchase tridicator gauges made in the United States.

www.marshinstruments.com


Marshalltown gauge
I just sent a check in to ACI-controls in West Seneca, New York for
75 and change with shipping included for a 3 1/2 square gauge with the bottom mount to replace the Chinese junk I was sold.
The have 4 different gauge models with 9 different temperature/altitude and pressure range values with either a rear mount or bottom mount with 1/2" N.P.T.
I am so looking forward to sending all that junk back to the boiler builder and getting rid of the 2 defective triple aquastats and gauges

    Winters is a domestic manufacturer of tridicators.

    The Winters tridicators do not have the altitude portion of a true tridicator that I saw in their literature
    I am just glad I have a good gauge coming and I do not have to deal with the plumbers I hired before this.

    Marshalltown also make them in something approaching a usable range (0-60 PSI, 0-260°F.) The majority of tridicators we see in the field have near-useless ranges.

    The tridicators with an altitude indicator, at least the ones I have seen, are just manually set to indicate the static pressure head required to fill the system when it is empty. It is just the elevation, in feet, of the top of the system above the gauge elevation.

    Sorry about my tardiness in responding; yes. that is how they are ment to work to show the plumber or homeowner the cold pressure in the system when filling it.

    The Marsh folks told me to set it at the12 pound mark to have baseline for pressure as The boiler is at ground level along with the heating loop.
