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

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!

As toxicmolotow already mentioned, we are also at around 5 bar (72.5 psi). That’s acceptable, so just try it out with that first.Well, not that the fittings will explode at 5 bar (72.5 psi)^^ Are there maximum values for that? Is pressure linear? So, is 4 bar (58 psi) twice the pressure of 2 bar (29 psi)?

4 bar (58 psi) at the inlet is quite decent... I’d look for the problem somewhere else...Apart from the filter – where else could there be restrictions here?

toxicmolotof19 Dec 2017 16:10Yes, pressure is linear. 1 bar = 10 m (33 feet) of water column.
If you want to be precise, the fittings should definitely have a certification indicating how much pressure they can withstand. The same should apply to the hot water system.
Personally, I wouldn’t worry about 5 bar. We once had 7 bar... Even the gentle shower felt like a scalp massage.

I’ll test it out – thanks for the help!
