When the pressure relief is pulled, does water come out? When the heater was installed, was the tank filled while the relief was open or several hot faucets left open? If not, you could have air pockets in the tank or lines that are the cause of your problem. Also, some heaters need expansion tanks. I've never personally had one but some applications require it.
