Watts pressure-temp gauge
« on: December 02, 2014, 06:53:38 AM »
Is there an adjustment that I need to do on my gauges to have them read correctly? I have them on the back of my PM 2840 on supply & return lines via 1" by 3/4" tee with a 1/2" adapter. The boiler is set to 185 and it reads about 170 right off the pump, went and bought a Nibco strap-on gauge and it reads 150 on the copper by the watts gauge (not a fan of these). I would think my thermostat is good on the boiler, everything else on this dragon seems real nice.  I would really like to know what my loss is but I don't trust my gauges.
