Using the following procedure you can calculate what the fill pressure should be for a given building: Given: Baseboard on top floor of a 6-story building with boiler located in the basement. Each floor is 10 FT. high; therefore the total height to baseboard is 50 FT plus 8 FT for basement = 58 FT. Given: Every 2.3 Ft of water equal 1 PSI.

If the bladder appears to be ok, then raise the pressure of the tank to 12 psi. After you get your expansion tank sorted out, refill the water into your system until the pressure gauge on the boiler reads 12 psi.

The required pressure is determined by the height of the heat emitters above the boiler. For ease of math, figure 1/2 psi for every foot of distance above. If it is 28', the fill pressure should be 14 psi. Ideally you want some positive pressure at the highest point in the loop so add couple psi to the calculated number.
