ᐅ Sewer pipes, drinking water lines, and heating pipes?

Hello,

since I couldn’t really organize my topic well, I wanted to ask if anyone can recommend a good manufacturer for the three types of pipes mentioned above.

Details:
The wastewater pipe should have insulation to prevent the "annoying" noises.

The drinking water and heating pipes should also have insulation.

Thank you in advance

Hello!

I don’t fully understand the question....... Water-carrying pipes are always additionally insulated for thermal insulation and decoupling; otherwise, I have mainly been concerned about the material (copper or plastic/aluminum).

Drain pipes are also available at a low cost with sound insulation (for drywall installation, it would be sufficient to insulate the vertical pipes). I am not aware of any tests regarding this.

Hi TomTom1,

thank you for your reply.

You are right. I will ask the question properly again.

1. Which material is good or best?
2. Which connection system? (I’ve read that push-fit connections might not be very good?!)
3. The whole setup should be as quiet as possible. Which insulation or soundproofing do you recommend?
4. Which manufacturers do you know for the pipes? (because you mentioned, "you can get them cheaply")

Thanks and best regards

Hello!

You are probably overthinking this a bit. In a single-family house, soundproofing is usually a minor concern because the potential for noise disturbance is much lower.

Besides, noises typically come from the burner (for example, with an oil heating system) or the toilet cistern. Water-carrying pipes generally do not produce their own noises.

With wastewater pipes, problems can arise if the pipe diameter is incorrect (too large).

If one product were significantly better than all others, then the others wouldn’t exist, right?

There are also factors like price and quality of workmanship. So if your trusted craftsman has installed a product 7,435 times already and now you force them to use something else, the installation will a) cost more and b) most likely be of lower quality.

Vibration noise protection in water pipes can only be achieved through decoupling—the material itself doesn’t really matter. Wherever the pipe comes into contact with other building components, sound is transmitted; thus, the INSTALLATION is what really counts.

For my current build, I have again chosen copper pipes. They have weaknesses (corrosion). Whether plastic would have been better will become clear in 10 to 20 years. In my previous property, a soldered joint failed once—see the explanations about installation quality. If something is done carelessly, the technology is secondary.

Insulation serves thermal isolation, not soundproofing. The best protection against vibration noise is NOTHING, because NOTHING transmits nothing!

Sound-insulated wastewater pipes have slightly thicker walls—the manufacturer didn’t matter to me.

I was satisfied with doubling up the wall at one critical point (wastewater pipe in the dining room wall) since mass helps against airborne noise; this had other reasons as well.
