We’ve just had our bathroom renovated and have had a new thermostatic shower fitted with a rain head and smaller handheld head. Both of these have extremely poor pressure.
Our boiler is a baxi 33kw with a flow rate of 13.5 l/m.
I tested the flow rate of all of the taps in the house and the shower (I don’t know what I’m doing at all so just blasted them all on cold)
We are getting 11 l/m from our ancient kitchen tap.
9 l/m from the bath tap (this is about what the expected flow rate is)
6 l/m from the basin tap (expected flow rate is 5 l/m so actually over performing).
And only 6 l/m from our new shower (I only checked the handheld head). If I turn the handheld shower head upside down the water rises about 6 inches! If I did this with our old shower it would’ve almost hit the ceiling! The paperwork from the shower states 12 l/m at 1 bar, which is what our boiler is at. So it is underperforming by 50%!
I’m now wondering what has gone wrong. We’ve moved the position of the shower so it’s different pipework, so is it possible the plumber has done something to cause this, or could it be the shower?
I’m absolutely gutted as didn’t spend thousands to get a lower quality of shower.
