cold water pressure is good but if i turn the faucet all the way to hot...it just seems to trickle down.

plumber from down under is correct, plus newer valves with the single handle will premix a percent of cold so you dont scald yourself. now if the lines are lengthy, smaller in diameter or both, then supply pressure will not open your supply check valve, but instead follow the path of least resistance. now where it gets bad, is when your hot is all the way on, you will have a cold supply of probably a shorter length and bigger diam, that doesnt have to fight the check valve. so as the hot trickles to very little pressure, so does the cold, since the single valve doesnt combine full port hot with full port cold, just partial port cold.
so if this is your faucet style, then basically you have a big um equal circuit which doesnt let either water pressure run. if this is the case, try an orificed water line,like a watersaver orifice on the cold side. hope this helps, but its just theory and basic hydraulics.

Check on your hot water tank for the outflow pipe.
On the pipe there may be a screwdriver adjustable 'grub' tap.
Put your faucet to hot and adjust the grubscrew. You should hear a change in water volume at the faucet.
BEWARE - This can increase the water temperature to boiling point !!
You should be able to get a decent flow without it being too hot. If not consider a 'heat as you go' system.
Just becarefull with the hot water, esp. if you have kids.

sounds like calcium build up in the hot water line or just your faucet is clogged best way to find out is to check the hot water tank it should have a pressure release valve on it if the water comes out good there then its your faucet then its just fix or replace

If your water heater is old enough it could be the heater itself. Most of the time low pressure is due to mineral build up in the piping system.
Take the hoter water valve apart at the sink and see it there is a lot of mineral build up.

Is the incoming water grant on? turn off water grant and eliminate warm water line, activate water slowly to confirm if water comes out of warm edge. If not you have a situation in heater. If water flows then you definately've an obstruction in you warm water line. Mark

It may be old cast iron pipes or could be the element in the water heater. If you look at the heater and its not leaking try opening the valve at the bottom to drain out the sludge. If you fill your sink and see rusty water cold or hot its the cast iron pipes.

The outlet connector on your water heater has a calcium buildup causing the pressure drop. Very common. Any plumber can fix the problem.
