Water connection outside from the kitchen - possible?

To my knowledge, only the toilet flush valves should have larger diameters, e.g. DN20, otherwise everything else is DN15.

I just googled a bit more. DN20 is usually recommended as the supply line to the bathroom and sometimes also to the kitchen; for the actual supply line to the individual tap points, DN16 is apparently sufficient. Only the supply line to a rain shower in the bathroom should also have at least DN20. Larger diameters are therefore always useful when the line branches further.

Hello,

Thanks for the answers. I just found out that the developer has not installed the screed yet and is now offering me a line with a frost-proof outdoor tap from the house connection to the gable wall for €630.

Now I have to say that our plot is only 200m² (REH) and therefore there is not really much to water.

The option with measuring in the kitchen seems significantly cheaper to me. Unfortunately, the question remains whether enough water will flow through.

I would have to lie, but our outdoor faucet planned by the GÜ also branches off from the kitchen connection. Our second unplanned one was branched off from the toilet before the screed (whether this was the optimal solution, I don't know – at least the installers didn't see a problem with it). However, it certainly didn't cost over €600, but about 250 including, frost-proof of course.

Check with your waterworks to see if they offer a separate garden water meter. This way, you have to pay for the water used in the garden and save on wastewater fees. For me, these fees are, for example, the larger portion of the water costs. The water itself costs so little per cubic meter that having your own well wouldn’t be worthwhile.

If this is possible, however, you have to run the outdoor water taps separately and cannot branch them off from the kitchen or bathroom. Although I consider >600 EUR for an outdoor water tap outrageous. For me, one was already included in the house price and I paid a flat rate of 205 EUR gross for the second one (on the opposite corner of the house).

Just for comparison.

When it comes to the prices of outdoor water taps, a flushing well is definitely worth it.

Not when the groundwater level is as low as it is here.
