Just bought a new faucet and replaced plumbing in the bath. No water coming out of the valve. Please help.?

we removed our old bathtub and everything that went along with it. We just installed the new plumbing with the valve for the faucet. There is no water coming out of th valve in either direction either to the spout or the shower head. We have taken the valve apart and it looks fine.Just bought a new faucet and replaced plumbing in the bath. No water coming out of the valve. Please help.?
!st off make sure you turned water on!


2nd- If you soldered in a new shower body assy, you have to remove the guts to it before you solder the pipes to it. If you did this you might have damaged the guts to the assy! If you removed it then you have crap stuck at it from the soldering and you need to remove it and turn water back on to flush it out. Then reassy it and try again. Leave shower head off until you flush it too!!Just bought a new faucet and replaced plumbing in the bath. No water coming out of the valve. Please help.?
does the new valve have integral stops ? they are little screw driver slots on each side of the valve . one on the hot water side and one on the cold water side . make sure they are all the way open . also make sure you have both hot and cold water on as if it is a pressure balance valve you might not get flow out of the valve without pressure on both sides .Also make sure you have connected the water lines to the proper connections , not mistakenly connected them to the putlet sides of the valve body . what brand is the new valve ?
Turn the water on to the house.
did you remember to turn the water main back on?
