ᐅ Age of Utility Connections in Older Homes – Do Utility Connections Have an Expiration Date?

We own an older building from 1921. We don’t know the age of the various utility connections. We received no information from the previous owner. Next week, I plan to call the utility companies and hope they can tell me when the lines were installed. Inside the house, everything is new following a renovation in 2017. At least the electrical cable coming in from outside doesn’t seem very old.

How old can utility connections reasonably be expected to be? Next year, a tightness test is scheduled here to ensure we can also insure against any pipe leaks. Of course, it’s possible that we will need to replace the connections first (the distance to the street is about 4m (13 feet), so hopefully the costs will be manageable). We recently removed a sick birch tree from the front yard. Its roots could theoretically have damaged the connections. Gas, water, and electricity are all present. For now, we hope that the gas connection is relatively new and that the other connections were refurbished at the same time. The gas heating system was installed in 2010. We don’t know if gas heating was used before that. Again, we received no information on this from the previous owner.

Does anyone have experience with this? What is the typical lifespan of water/sewage, electrical, and gas connections?

Normally, the connections entering the house, including the transfer points, are the property of the utility provider, who also maintains the connections and ensures operational safety.
During a major renovation of the internal house installation, the respective installer may take care of having the utility provider revise or renew the connections if necessary.

According to the local utility company, everything from the house to the first junction is our responsibility. That was their statement over the phone. However, I need to verify this because, based on experience, information given by phone can often be incorrect. For the building insurance, we had to waive coverage for the few meters from the basement wall to the junction since no current leak test is available. This test must be carried out by a professional company by 2025 at the latest, as legally required. In any case, I have received the plans for electricity, water, wastewater, and gas, and it turns out everything is very different from what we expected. We have an end-of-terrace house. Our gas connection runs through the front garden of the immediate neighbors, and in the middle of their basement, the gas line comes over to us. The pipeline, which is already partially plastered into the wall there, looks very old. Our gas meter or distributor, whatever you want to call it, dates back to 1995. I don’t know how old the supply lines are (that is, everything from the street to that box). Our water and wastewater connections are actually located two houses away in the front garden of other neighbors. The installations (cast iron... look like original 1921) run along the exterior basement walls of those neighbors, over the immediate neighbors to us, and then come out through the outside wall of our basement. Only the electricity runs through our front garden and then splits into the connections for the neighbors and us. It will be interesting when these need to be renovated or if any damage occurs. Luckily, we have good neighbors.
Regarding the location of the telephone lines, I am still waiting for a response and don’t have more information yet.

Inside the house, as mentioned, everything has been renovated. Only the supply lines are the original ones. From the electrical/gas meter and house water filter onward, everything is new.

Municipal utilities are often still small, independent providers with unusual regulations.
I am also familiar with these dual electrical connections; in our area (EWE), during renovations, connections are separated without the need for additional components, and each household receives its own connection free of charge.
Perhaps contacting an installer who is also authorized by the municipal utilities (important) could be helpful.
