i took on a job that I regret. I was asked to do a municipal sewer for a house that i am doing the plumbing for.
The engineer has told me i have to do an air pressure test on the line.
He at first told me I need to test it at 3.7bar for five minutes and then at 2.5 bar for two minutes.
This sounds more like a destructive test and I think he has some decimals displaced.
I suspect it is more like 3.7kpa.How could I test this sewer line to 3.75kpa?
The sewer is 160mm diameter (6") and is 25meters long.I have heard of a machine called a manometer . Could I use science to make a simple machine.?
I have been told that for every meter of height the pressure in a pipe is ten kpa so I would think if I had a column of water of 375mm I should obtain a pressure of 3.75 kpa.Its how to hook this up that puzzles me.
Could I use a compressor?How long would it take to pump a pipe that is already full of air to 3.75kpa?
