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).

According to DIN standards, backflushing should be done every two months, or the filter should be replaced every six months if it cannot be backflushed.

Everyone, hands up who has done either of these in the past 12 months...

I am interested in how this works in practice.

If nothing breaks on the backwash filter, I would just extend it a bit as well...

Flushed annually. And I can’t even say that the filter is difficult to access...

Every now and then, when you happen to think about it... So since moving in in 2015, maybe four or five times?

But there’s quite a bit of stuff floating around in the bucket. At least it’s not the worst investment.

Has anyone cleaned the small filters in the faucets? It’s worth doing regularly.

Only clear water came out of the backwash filter here.

There are automatic backwash filters, also called "backwash filter automats." With these, you practically don’t need to handle them anymore. For manual backwash filters, you should provide a direct (open!) drain pipe or hose. That way, you save yourself from using a bucket, and the effort for backwashing is almost zero.
