ᐅ Water Pressure in New Construction – Standards and Possible Improvements?

Created on: 19 Dec 2017 14:56

Good day,

we recently had a single-family house built, and now the shower fittings are installed. Unfortunately, the water pressure is so low that the lady (and I a bit as well) have trouble getting the shampoo properly rinsed out.

The rain shower with massage function is more like a hesitant trickle. It’s not due to the showerhead itself; we tested by connecting the old showerhead from our rental apartment, and the water pressure is clearly lower here as well.

I have several questions:
- Is there a standard regarding water pressure?
- How can water pressure be measured? Possibly without removing the fittings...
- What options are there to increase the water pressure?

Thanks!

Where and how is the water pressure for the hot water generated?

Initially, it is the same pressure. The hot water just takes a detour through the hot water tank, etc., where flow losses occur, so hot water usually has lower pressure at the outlet. In my opinion, however, the problem is before the filter, as I already mentioned.

The fact is: The shampoo washed out within seconds there, here I need to rinse with the shower head for 20-40 seconds.

Hmm... are you building where you used to live? Or do you get the same water from the same water treatment plant?

Maybe it's also the combination of lower water pressure and noticeably softer water than before?

I find that interesting. We have noticeably higher pressure in the hot water compared to the cold water. Could this be related to the water heater and the circulation pump?

Well, before the filter there is only the pipe that goes from the wall to the outside. Do you mean simply not enough pressure from the supplier?

The water is indeed much softer because of the water softener (which unfortunately does not show any pressure). I just judge it by "how long it takes to rinse the shampoo out."

We are about 10km (6 miles) away from the previous location – but unfortunately, I don’t know where the water comes from.

There you go, well, at least part of the answer.

With more lime, you bind significantly more shampoo and soap at the same water pressure and water volume. You should actually notice this when washing your hands as well. You now need less soap than before, or it takes longer to rinse the soap off.

Oh, I wasn’t aware of that at all. Thanks for the information! But the lime content shouldn’t affect the feeling of the shower spray, right?
