Hello everyone,

I was advised to have a video pipe inspection carried out in my house from the 1960s, since the pipes are quite old and probably have had little water flow over the past few years. I don’t have any general wastewater issues.

Unfortunately, I can’t really assess the usefulness of this. Is it worthwhile? Does it make sense?

Best regards

What should it cost and never have any problems?

I have only had the house for a few months, and the water seems to drain normally. So, no problems for now.
Two different plumbing companies have recommended an inspection.

The costs would roughly be 20€ for travel, 25€ per 15 minutes of work (draining or video recording), and 50€ if I want the video. All prices are excluding VAT. Apparently, two hours should be sufficient.

Possible additional costs if there is a leak... I have no idea how much that would be.

Hello

The water has been draining perfectly for over 50 years. I would leave it as is until problems arise or the pipe needs work for another reason.

A company that also carries out wastewater pipe renovations inspects a pipe over 50 years old and discovers............???
probably things that should be renewed or repaired as a precaution?

Both options are possible and can be correct. You need to weigh the risk.
I would wait.

I decided to have the inspection done. Today was finally the day.
Here is a brief report on my experience:

Regarding the condition of the pipe from the house to the sewer:
  • The section of the wastewater pipe under the slab foundation is fine.
  • Right at the end of the house, there are two small bends and a pipe break. It’s more like a large crack along one side of the pipe, probably caused by significant ground settling in that area.
  • After that, every joint appears damaged or broken, and there are some shifts. As a layperson, these didn’t seem too severe to me.
  • At 10 meters (33 feet), there was a significant downward shift, causing water to stand up to half the height of the pipe there.
  • After that, the sidewalk begins and the condition looks good.
  • Some joints supposedly show early root intrusion, but to me as a layperson, it looked more like dirt. No typical root patterns were visible.

I believe much of these issues were caused by the vegetation above the pipe. Right above the sewer line, there are old stumps of deep-rooting trees. Some large bushes are still present as well. The pipe is located about 1.5 meters (5 feet) below the surface.

On the other side, inside the house, there are slight deposits which increase significantly in an area that should only serve as an overflow protection.

The whole process took just under an hour. I did not request the video since I was personally present.

probably things that should definitely be renewed or repaired as a precaution?

Oh surprise, I was advised to renovate everything. Both the external area and the part inside the house under the slab foundation. How convenient that I am getting quotes directly from the same company. Seek and you shall find

I’m still undecided about whether to proceed immediately.
All the bushes and plants will be removed first so that, as a layperson, I hope no major shifts will occur so quickly again.
I will discuss everything again with my plumber.

So far, I do not regret having the inspection done.

A tightness test (leakage test) is sometimes even mandatory, depending on the age of the pipes. I believe we should actually have one done as well (built in 1921, probably with the original pipes), but we haven’t had it done yet because of the costs. The test itself is not expensive, but the costs for any necessary repairs can be significant, and we don’t have the money for that at the moment. For example, because the tightness test is missing, we were unable to insure the pipes outside the house up to the municipal utility company. That’s another point to consider. If the test had been available, additional coverage would have been possible without any problems.

So, long story short, just google “tightness test mandatory” or something similar and read up on it… it’s definitely relevant for owners of older buildings. For us, a discussion with the utility company was unfortunately not helpful. And nobody can tell us how old the pipes on our property actually are. Since the wastewater pipe from the basement to the outside is still made of cast iron, it’s probably very old and likely the original from 1921.
