hot water won't enter radiator
I have a gravity fed system. Just recently did a bathroom renovation. Had the radiator removed and sandblasted and reset. Now hot water won't go into the system. I've bled air from the radiator and water does come out of the valve. The original floor was removed and replaced we new sub floor, concrete and tile so it's about 3/4 to 1" higher than before. The heating guy did pull the radiator to look for debris from sand blasting and inspected the valve and and it is open and functioning. I'm not sure what the next step should be. Would the floor level change impact a closed hot water system? Thanks.
