ᐅ Are water filters mandatory in household plumbing installations according to drinking water regulations?

Hello,

I want to have some supply lines and shut-off valves replaced in my house (Albtau).

The plumber is recommending a whole-house water filter installed after the water meter and says this is mandatory according to drinking water regulations.

Is he correct?

The fact is, it has worked fine for the last 20 years without one, and I don’t know anyone living in older houses who has one.

Thanks for any advice,
Daniel

PS: Pressure reduction is not required according to the supplier, as the pressure at the supply point is between 2.8 and 3.3 bar (40.6 and 47.9 psi).

Yes, it is mandatory when making changes.

Every house without one should have one retrofitted. Even older non-rewindable models should be replaced with rewindable ones. This significantly reduces dirt. All larger particles are held back this way. Such a filter with a pressure reducer costs approximately 120 to 200 euros (plus installation). It should be worth it for everyone’s health. It also prevents larger deposits caused by dirt in your own water pipes.

Thank you for your reply. That's a shame. I would like to avoid that, as it is inconvenient to repeatedly access the area where the pipes are located to flush. There is no lighting and some other discomforts... I also can't seem to find the part where that is supposed to be written.

I assume this is covered in the utility regulations or drinking water ordinance.

You could install a loop or something similar to access it.

And once or twice a year, you can simply use a flashlight.

Or you could hire someone to maintain it, then you can have a coffee while it’s being taken care of.

His statement really shocked me, telling me I should go down there every month. I guess I will just extend the interval to quarterly and hope that is acceptable.

As far as I know, my water filter has a six-month replacement interval. Changing it monthly is quite intense.
