it has a guard dog low water cut off

your not low on water the boiler could be full and be low on pressure


you have no pressure you have raise the pressure with the fast fill

the fast fill? I have 5 gallons of (no burst) should i use that or water? do i take a garden hose and stick it in a bucket of water and open the valves so it will draw in the lines?

if you know how to add " no Burst " then yes you will have to replenish your anti freeze but the psi must be rasied

ok thanks, XXXXX XXXXX sure if thats how or not? how do i raise the psi?

there is a valve going to the boiler from the water heater aera there is a device its eather

green or brass with a tab at the top or its a brass loking ufo with a rocker to be lifted

as you add the water loook at the guage and stop at 12 to 18 psi

ok I looked all over its a bradford-white indirect tank and i see no such valve? would it run under the house or no?
no there is a 1/2 copper line going to your boiler ( it goes from the boiler to the domestic water supply ) it fills your boiler there should be a valve before it then a device used to fill and maintain the system psi
