I'm a list maker. I freely admit it. I have lists of things that would make you think to yourself, "Huh? Why? This guy is crazy!" For example, I keep track of the largest home I've inspected (15,462 square feet), the smallest home (362 square feet), and some esoteric things that only I would think to list.

Such as the highest and lowest water pressure.

Today's inspection found the water pressure at about 133 pounds per square inch (psi):

40-80 psi is normal, although I prefer 40 psi.

Many people will increase the water pressure because they don't get good water flow at the shower heads. The solution to that problem is not to increase the water pressure, but to get a better shower head or, if your locale has mineralized water like we do here in San Diego, take the shower head off and soak it in something like CLR for 24 hours.

This was another vacant foreclosure for which utilities had been turned off. However, both Realtors had done their job and had the utilities turned on for the inspection. Except for the water. The bank had notified use that there was a "huge leak" in the bathroom at the toilet. A visual inspection with the water turned off showed nothing out of the ordinary. Lifting the toilet tank lid showed that the rubber fill-up tube had come loose, so I put it back on (see picture).

The bank's representative then turned on the water. Sure enough, the water pressure was so high that it blew the tube back off and water sprayed everywhere in the bathroom, so I can imagine someone using the toilet and flushing it, only to have water pour out the back of the tank. The easy fix, of course, is to lower the water pressure by installing a water pressure regulator, or replacing it if it's defective:

The highest water pressure I've ever found was 176 psi. The seller of that property disclosed that he was selling the house because the water pipes, faucets, toilets, etc., were constantly leaking, and his plumber could not find the problem. Uh, I could! 176 psi! My Client bought that property and annual follow-ups indicate no plumbing problems.
