[AMRadio] 220 vac line

[rbethman]

Believe me - I've used every type of meter, to include one Weston direct 
reading panel meter, a TS-505D/U, a brand new Digital MM - NON Harbor 
Freight, and oscilloscope!

We've had this issue for almost as long as I've lived here for the last 
23 years.  Everything in this part of the city is underground.

ALL the utilities are their own quirky selves!

I put a pressure gauge on the little goose neck that you put the shower 
head on.  I'm in a split level Foyer type construction.  The shower head 
I chose is the highest in the house. I got 130PSI.

So immediately put in a pressure reducing valve in the main line from 
the street.

This city of less than 160,000 has expanded a LOT since I moved here 
after retiring from Uncle Sam's Employ.

They have been getting around the "issues" by pushing Voltage, and water 
pressure, in lieu of upgrades to account for the heavier use!

So when I tell you the voltage, please don't take me for 
"intellectually" challenged.  I'm one whom worked Power Production and 
Distribution while in Uncle Sam's Employ.  To include a very intense 
course on Nuclear Power.  The have even board certified us.

It is what it reads.
