Bathstore goes into administration

Maybe it’s just a quiet time of year for diy work, with most people going on holiday ?

The manufacturer tells me the flow rates of the Spey 2 shower are:

0.2bar: 4.2 l/min

0.5bar: 5.6 l/min

1.0bar: 7.7 l/min

2.0bar: 12.1 l/min

3.0bar: 14.1 l/min

I have an incoming water pressure of around 3 bar max. I guess if the boiler output is limited to less than 14.1 l/min, then that would be all you get.

The flow rate at the existing shower on the stop is 11.5 l/min. Would it be fair to assume a similar flow rate would be achievable in the ensuite?

What I'm getting at is would there be any point replacing the half inch feed into the house from the 25mm-fed cock outside?

 

[JohnD]

when I did that, I got a significant increase in flow.

if your existing pipe is old, it might also be thinking of leaking.

If it is lead, you might a subsidy or free connection of your new pipe.

 

[securespark]

Not lead, Imperial copper.

What hot water system do you have

 

[securespark]

WB Greenstar 34CDi.

Combination boiler. This I would imagine gives a good flow rate. I'm not sure how much. What is the bar pressure coming into the property?

 

[securespark]

Around 3 bar.

As I say, the mixer in the bathroom gives 11.5 l/min.

You should have a good shower whatever
But it may drop off if somone else is using a tap.
Whats more important is the working pressure and what that is at peak times

Is it because of Brexit?

Bathstore isn't the first business to go down the plughole and it won't be the last.
Nowt to do with brexit.

Simply because they knock out shiiiit

Cheers.
This is what I can't get a handle on. The water pressure could remain the same (eg 3 bar) but the flow rate might be great (tap fully open) or poor (tap nearly closed).
What is the working pressure and how do I measure it?
Are you thinking what it would be on a weekday am with a tap running elsewhere?

Have just run a test. I replaced the shower head on the thermostatic mixer shower in the bathroom with a gauge and turned on to full. I checked the readings over 20 minutes: between 1.75 and 2.2 bar.

Then I turned the cold on full in the bath. This caused a sharp but gradual drop on the gauge (still attached to the shower hose) right down to 0.1 bar. Other taps cause a lesser drop to around 0.8 - 1 bar.

Would changing the incoming supply pipe really make such a difference, especially when factoring in that most of the pipework within the property is 1/2" or 15mm anyway?

And, bearing in mind that drop to 0.1 bar, perhaps I would be better off with the Mira which claims to perform better at low pressures?

I know there's a lot of marketing guff out there, but Mira say:

"Mira Magni-flo™ technology means you can have a drenching shower even with water pressure as low as 0.1 bar."

a drenching shower even with water pressure as low as 0.1 bar."

Niagra Falls have virtual zero pressure where the water starts to fall. But then the cross sectional area of the water supply to the falls is bit larger than that of a 15 mm diameter pipe
