This is the 'Y' pipe. Actually it is not a Y, it is a straight pipe with a clean out attached to it. We replaced it with a 90° straight pipe on one end and a ABS straight pipe on the other.
Here's another close up of the leaks coming from the Y connection. See how they joined the pipes together in those days?
This is the straight pipe that needs to be replaced. You can also see the connections. Back in those days, cast iron pipes were used for plumbing. Nowadays we use ABS and PVC. We replaced the pipe with a length of ABS instead of going back to the cast iron. See the water dripping?
See all the active leaks coming from the pipe? Some have rumored that the use of cast iron pipes was because they were more quiet than the ABS pipes. Facts are that this was not the reason they were being used. The reason they were used is because this was the only kind of pipe available in those days. ABS did not become a plumbers favorite pipe until the mid 1970's. They are just as quiet, more cost effective, do not rust, easier to work with and are glued together instead of being strip banded. ABS = acrylonitrile-butadiene styrene I am currently looking up when it was converted from its original invention (which I think was for the airline industry because of its durability and light weight) for plumbing use and also who invented it. You gotta love being retired.
Some of the advantages of ABS plastics are . . . ABS is:
- Flame Retardant - Good
- Heat Resistance, High
- Affordability, Very Good
- Impact Resistance, High
- General Purpose usage - High
- Flow, High
- Processability, Good
- Durability, Very Good
- Ease of use, High
