I have high water pressure at the front yard spigot, however, the
pressure drops substantially inside the house and even further at the
rear yard spigot. I have checked the house water filters and unit,
they are clean and fully functioning. I have replaced the water
pressure control valve in the front as well. The house is on a slab
and there is no evidence of a leak. Any ideas as to the source of the
problem?

Did it used to be higher at those places?

When did it change?

Did it change gradually or suddenly?

Etc.
