Hello everyone,

I am about to buy a single-family house built in 1960. The exterior shell is in excellent condition and hardly needs any work. However, the interior requires quite a bit of renovation.
Unfortunately, the seller does not know how old the water pipes in the house are. A new oil heating system was installed last year, and some new copper pipes were used there. However, the pipes running through the ceiling to the radiators are still the older ones.
The remaining water pipes installed in the house are also all copper (soldered) and show no greenish discoloration or other damage.
How would you handle this? Many people tell me to just leave them as they are, and if something happens eventually, the insurance will cover it.

Thank you very much for your opinions!

The water meter slip shows a name; maybe you want to remove it.

Best regards

Does this make the difference between buying or not?

With copper pipes, corrosion eventually occurs, causing the pipes to burst. If you’re unlucky, this might happen while you’re visiting your in-law for the weekend. That’s definitely unpleasant, and you’ll have to unexpectedly replace the pipes and carry out building drying.

For me, copper water pipes are something I would definitely replace before moving in if they are of a certain age. After all, you don’t want to have to break open the walls again in a bathroom that’s only two years old. And if the age is unknown, you can assume nothing has been done 😉

Check with your water supplier to find out the pH value of the water.
pH value — copper pipe = pinhole corrosion.
After that, research the topic online, and then you can decide for yourself whether it makes sense or not.

If I redo something, I would of course replace the pipes as well. But if the bathroom is staying, I wouldn’t change the pipes either.
