useing compressed air to clear water pipes


It was suggested to me that I use compressed air to help clear a hot water pipe to my bathroom sink. How do I go about doing this, and is it safe?

Hi Ted. Is the hot water pipe to your bathroom plugged?

Is it safe? As long as the air pressure used to blow out the line is less than the burst pressure of the pipe, sure it is?

How do you do it?

Why not check the site map for references to blowing out sprinkler lines? The concept is the same, and there is lots of info on that on this site.

If the water line is blocked, depending on what is blocking it, the use of compressed air might or might not be successful. I cannot be certain as I don't know what the blockage is, or the pressure rating of your pipes.

Good luck,

Bill

CFM of air eqivilant to gpm for blowing out pipes?

by Robert Schilke
(Katonah myth)

A lot of miss information, cfm of air eqivilant to gpm for blowing out pipes and sprinklers?

In purchasing a compressor to blow out pipes and sprinkler systems , the comparison of cfm to gpm is a question always asked, what size compressor do in need? In the past it has been said that a 2:1 ration cfm to gpm is min rating. There is always friction losses in the length of the pipes and the mains. No real number has ever given.

Hello Robert. While the info was on the site map page before, I've rearranged it so that it is under the category Sprinkler Related Issues.

Go there and follow the links for some "real numbers".

Cheers,

Bill

by MM

How many CFM do I need to blow out an 8" schedule 80 pipe 60' long thats filled with water.

The pipe is underground that runs to a pond and the end of the pipe is covered with leaves. I wanted to clear the debri by blowing air through the pipe.

Mark, please see the pages linked from the site map that have to do with blowing out sprinkler lines.

The information you are seeking is already there, though for sure, an 8" pipe 60 feet long is going to need a ton of volume. Not necessarily a big compressor, but a big tank.

Cheers,

Bill
