plumbing info/specialist needed

[kennybs]

Let me tell ya, I been a licensed master in the city of buffalo for over 25 years and doing this shit 10 years before that, the houses don't get much older than that, Hell we still have lead services and lead bends. Tile repairs and tile traps are still done but usually not as a first choice, there are usually other factors involved such as cost or limited space.

Today some State Codes don't even allow the use of clay tile anymore, even though many of our older cities are built on it.

Just so you know we have one guy here on the board that use to install the old oak mains with his dad, right JP ;)

Sewer pipe joints these days are press together with a built in rubber coupling at one end. The pipes push together, with no glue, and thus can expand and contract as needed. It is usually green in color, and goes by the name SDR-35.

I have lead service and a lead bend. Most older houses in chicago have them if the service has never been repaired or rebuilt.

although it is time for me to replace the horizontal pipes inside the house.

Some wood piping has survived from roman times found in the ruins of the structures that were along Hadrian's wall.

Hey Kenny, You must be bored. Anyone who thinks clay pipe is some kind of superior product for sewer lines is really not even worth the effort. Kind of like someone else posting about SDR35 being a good choice. This thread is cross posted so there's a lot of homeowners and wannabes replying here from another news group. So, like Kenny I am a 30+ year Master licensed plumbing contractor. The absolute state of the art and the best overall product available today for "most" drainage applications is............. Schedule 40 PVC-DWV....... Period. Now, there are special conditions that might cause you to make another choice, but any of those choices are a compromise giving up the durability and quality of PVC. If it is a public space where people could get trapped during a fire and smoke inhalation could be an issue (most codes address this) then cast iron would be a better choice. There's also ABS that is still being used in some areas of the country but because of it's unstable linear structure it is a poor choice. There's also a cheaper PVC line called "Foamcore" where foam is sandwiched between two thin layers of PVC...... I don't even allow the purchase or use of it in my company. If you happen to be building a chemical plant and you are going to be generating acid waste then you want to choose Duriron or one of the crosslinked polybutalenes or maybe even some Pyrex bead to bead or ......... clay terra cotta for certain types of high ph acids. The wall structure of clay is a joke so plants that have to make this choice will usually try make sure the clay is going in an unimproved area so they can dig it up and replace it every few years. Back to non-acidic wastes - there's an SDR series of piping available including from thinnest wall to thickest wall SDR-41, SDR-35, SDR-26. The '41' hasn't been readily available for most parts of the country for years and was a paper thin walled pipe for shallow sewers in sandy soils. The '35' is still available but it's primary intended use is exterior STORM water, not sanitary systems. The '26' is primarily for exterior sanitary sewer mains. There's also the polyethylene and A2000 family of piping systems. These are also for site storm water. There's a few others, but the main point here is that there are lots of piping systems in the world and the best one for a particular application 20 years ago, or 50 years ago, or 100 years ago is not going to be the best one currently. Those are decisions that experienced licensed professionals have to make based on the totality of the circumstances.

I'm sorry, but your knowledge and years of experience don't hold a candle to Kenji's 100 year old place with clay tiles working just fine. His contribution is all the information we need, thank you very much.

Bob sometimes it's just fun! The responses are even funner!

In the past year I made a move from NY to AZ. What a culture shock in the trades division. Here to be considered a licensed plumber you must have a total of 8 hours on this side of the border.

ROMAN WATER STILL ON TAP

BBC News - UK 6 February 2004

Archaeologists have discovered a 2,000-year-old water main built by the Romans - which is still working.

The find has amazed experts at the Vindolanda Roman fort in Northumberland (England).

During ongoing excavations at the site, workers discovered a 100ft stretch of wooden mains, which at one time fed the fort with water from nearby springs.

The pipes were constructed by drilling large lengths of alder, which were joined together by oak pegs.

..."The fact that they were still working is quite incredible, but it was also a nuisance because they flooded the excavation trenches which had to be pumped out every day..."
