I have seen similar problems with cast iron piping under kitchens. The piping I witnessed was probably 20+ years old.
The question I would ask is why was ductile iron used for drainage piping?
In my neck of the woods, where the International Plumbing Code is used, ductile iron is not an...
If you are using copper piping, usually (at least where I have seen it done) you would switch to type "K" tubing without any joints (Use the type that comes rolled.) This does not require any special fitting.
Keep the piping under the frost line.
Provide physical protection for the...
ASPE (American Society of Plumbing Engineers) has some wheels that they recently developed. I have not obtained one yet, so I do not know how user friendly they are. I still use the old method of counting and comparing to the tables in the code.
If you are sizing the water pipe, I use the code...
aharcourt,
I like your perspective. Go where the needs are. I was once told that no matter how advanced the world gets, it will always need ditch diggers. Find something that somebody needs, get good at delivering it, and reap the benefits. If you are worth it, the money is there
I once...
spector,
I could not agree more.
That plumber had no business connecting to that equipment. Where I am at, you can have plumbing contractors who do just the plumbing, or you can have a mechanical contractor who could do either plumbing or the mechanical or both. I once worked for a plumber...
As I have said, there are good plumbers and obviously in spector's town, there are bad plumbers. Talk about "don't drink the water"
I have never said that HVAC/R is less important than plumbing. I work around a lot of HVAC engineers and have nothing but respect for what they have to...
Veekrish,
I know what it is like to try to find materials on plumbing engineering. I am a chemical engineer by education and got into plumbing more from an economics perspective than a technical perspective. I got laid off from my job and had to "rediscover" myself.
I used the...
I am not sure it would help.
I have been using linetypes that have the text as part of the file. This allows for text to be put in the line at predetermined spacing, but it is difficult if I want to move the text a little on the line. I usually have to break the line at a point which is hit...
I am trying to find a way to easily insert text into lines on my piping drawings to designate the type of pipes I have.
I want to be able to control where on the line I put it no matter how long the line is. I want to be able to control the orientation of the text, also. I want to do this so...
I have found that a good starting point are the Means Estimating Books. They are a series of books issued every year which details most if not all aspects of estimating in the construction arena. They offer a good guideline so you can get most aspects of the job.
As I said, they are a good...
spector,
Respectfully, I could not disagree more with "Plumbing design and install is driven strictly by code". When an engineer has to hide behind a code for the adequacy of his design, he is not worthy to be an engineer and should have his license revoked. Does he stamp his...
spector,
I acknowledge that there are a lot of advances in HVAC. While not as many, there are also advances in Plumbing.
The mechanical realm also has codes it has to abide by to be proper. So plumbing is not alone in that.
Plumbing deals with a lot more than just drainage. It deals with...
I agree with you that the 16 button are intimidating. I do not think I could master it. I commend you that you can.
I personally prefer a customized system which includes a combination of the wheel mouse, keystrokes, toolbars, menus. I am not the fastest, but I am fast enough which is good...
I am looking for observations/explanations from the forum about something I see in the AEC industry. I am putting it in this forum because I think it will be read by more people than in the Plumbing Engineering forum
I have worked for/with several AE and Engineering firms as well as mechanical...
Sovent piping system is popular in many countries in the world except the US. It is recognized as a viable piping design especially for multi story hotels but the codes in the US have yet to formally recognize it.
