Water pressure in most of house is ok, only Tub and Shower are low on pressure. Could it be the valves?
Question:I have a single faucet mixing valve. Even with no shower head on the pipe there is still very low pressure. Within the wall the piping is 1/2" PVC.
Answers:
There are several possibilites for the low pressure. First - check the individual shut-off valves at the tub for the hot/cold water to make sure that they are turned on fully (BTW, is this a problem that just developed, or have you had it for quite awhile?). You could have mineral deposits in the shut-off valves, or in the faucet itself. Is the problem mainly with the hot or the cold, or is it bad in both?? What make of faucet is it?? If it's a Moen, you could try replacing the cartridge. If the problem is equally bad for both the hot and cold supplies, I would suspect that the problem is the faucet itself.

yes
i dont know about the plumbing up to the shower, but it shouldnt be pvc all throughout. could be coroded pipes leading up to the bathroom. Thats the problem we had in our house.
You could have some corroded pipes or it could be lime deposits. If it is lime deposits, you may end up replacing the pipes and the spickets.
Pick up a little shower head at your home store. It is for low pressure and works wonderfully. Our tub and shower are the farthest point from our water source and have low pressure too. I have never been happy with the tub pressure.
you could have a water saver in there
