My pressure guage at the entrance of my house reads ~60 psi. WHen i open the farthest Lav cold water, the pressure drops to about 45 psi. Is that normal? I am in the country on city water. There is a pressure regulating valve at the meter by the road, and it enters my house about 365' later. The lav is roughly 75' of developed length of pipe away from where it enters the house. The toilet next to the lav also causes the pressure to drop about 12 psi.
I don't know exactly how big the pipe is from the meter, but the previous owner told me he thought it might be 1-1/4". Coming into my house, though, is 3/4" pvc. The rest of my house is plumbed with CPVC, with 3/4" main trunk and 1/2" branches to fixtures.
One more thing, the water pressure out of the lav faucet is high for a few seconds, then drops off.
