I've used the NEC for a good 20 years of my career, but the last 10-12 years or so, I really haven't had the need. My use of it was for industry, not residential, so I really don't know everything that's required for residential.
A few months ago, I wanted to help my father replace his...
I actually created a Google AppSheet, which is a very basic database that keeps the information stored in Google Sheets.
I was trying to simplify my request to only that of the formulas needed to estimate for missing data, or data not taken with a common frequency.
I have the following...
I volunteer for a water utility system in the mountains of Colombia, S America. All of us are volunteers. It's community of about 190 houses/farms that gets water from a mountain stream.
The government has asked us to install water meters on each house, which we are doing now. But, they don't...
Another water pressure problem in Colombia.
The lines in the picture represent 1/2 inch PVC pipe. Point B to C is about 50 meters. Point C is one user. The 4 branches leading 'down' are 4 other users along the line.
We don't know what the distance between A and B is. A is connected to a...
Thank you for everyone's ideas and suggestions.
We ended up installing 200 meters of 1" pipe from the main header and that solved the problem. Cost for a trench (labor) and piping was under $1000US, and it helped a few other customers along the 200 meters...
Thanks for the response.
Several of the users of the Aqueduct have 500 l-1000 l tanks on towers outside their homes. Not so much for pressure, but because we often loose our water source due to landslides, etc..., so this gives them a buffer.
One very wealthy family does have a tank and...
Yes, that's it!
And now that I see the drawing, I did a similar fix ~10 yrs ago here for someone else in a different location. But, I put in a homemade orifice in the cold water line... completely forgot about it.

All great questions. I should have been more thorough.
The water heater turns off (turns off the gas to the heater) as soon as the cold water to the shower is turned on. So, while there is still water flowing through the heater, the heater's flame turns off....I'm assuming there is a pressure...
I'm a Electrical/Instrument/Controls Engineer in Colombia, S. America.
I volunteer for our local water system, up in the mountains helping with design and changes to the system. We get our water from a creek, that then flows through a settling tank to knock out any heavy sediments, then the...
Yes, there is a 1/2' pvc pipe at the base of the two tanks that allows equalization. It was there from the beginning...according to the 'plumber' who has worked here for 30 years. I just don't understand why there would be two tanks, and not one.
There is no energy/electricity in the area to...
White pipe at the bottom of the tank (halfway up the side of the wall is the bottom of the chlorine tank/basin) is the outlet that drains into the water tank below.
The 1.5" pipe (and white 1/2" pipe) at the top is to fill the chlorine tanks with water, since we mix the chlorine in a 20 liter...
I live in Colombia, South America. I was an EE and Controls Engineer in the US for 30 years.
I volunteered for our local water system where we live. We're at 1700m altitude outside a small village.
I've been able to fix several problems in our water system, but I'm not sure about this design...
We had these colors to be used on drawings listed in our engineering guidelines...and I found the same in the next company I worked....

Just found they are called "Tablet Arms"
Thanks for leading me to the right direction!

Yes...description of axes would help. That's been my problem...I'm horrible trying to find the correct words to describe what I'm looking for.
The Auditorium desktops are an excellent example of what I'd be looking for....
Thanks...
