suggestions please

I went to a job today where a client wants 3 bathrooms all with baths and massive 10 inch shower heads. One of the bathrooms is on the 4th floor. He has 3 bar pressure constant when running all taps, and flow rate goes down to 9 litres a minute in top shower and bath with all basins and kitchen sink running. His mains pipe is 25mm. He has 210 megaflow which ideally should be 250 to 300. But I said he should try with 210 as highly unlikely everyone would use all at same time. Obviously the mains is limiting the flow rate, so would a 35 mm main do any better.

Thanks guys

Would a acumulater help ya ?

I was thinking of one of these accumulators but it's the storage space that's needed for it you see

 

[Destroyer2813]

How easy would a upgrade be though without guaranteed success

 

[mutley racers]

Bit of a mission really. Take up paving in front for 3 metres is the trickiest part.

As a idea I did a unvented last week new 35mm main 4.bar running pressure and 25+ltr min, but obviously may not be the same for you

Get a mole man in, no lifting the pavement then

Was that 25 litres with all appliances on? I have 18 litres on outside tap with all appliances running but then that's split so 10 litres at appliances. Need more flow as I believe stable 3 bar dynamic is good. Just a bit weary to tell guy to put 35mm in and it doesn't make much difference

They are expensive a. About a 1K I believe.

 

[Ermintrude]

Well that's the price then plus 20% for I

I do like the sound of the 20% on that but, if it doesn't help, I am in the poop

 

[Ermintrude]

Measure dynamic at stop tap. Oh you need to dig a hole.... Well that's a technical survey so cost plus 20%

Or fit a break tank and a booster set

no :nono: way man !!! I've got a number in the van from a guy who did a job in hampton for me about £400 for 5m run

no fecking way man !!! I've got a number in the van from a guy who did a job in hampton for me about £400 for 5m run

Now i like the sound of that. Cheap as chips

Space is a problem. Outside tap was next to stop tap.

No

What's an accumulator? I was going to suggest storage tanks feeding a pump like a grundfos MQ
Is that the same thing?

How can u say no and then ask what it even is or does

 

[Neil K]

Sorry the no was a typo. Disregard the no and read the question again. Apologies

Increasing the pipe diameter will increase the flow rate (log scale so significant increase), however, this is also accompanied by increase in velocity and noise.

no :nono: way man !!! I've got a number in the van from a guy who did a job in hampton for me about £400 for 5m run

Any chance of that number feller?

 

[mutley racers]

What's the guide to sizing an accumulator or breaker tank then? If it has to be for both hot and cold it is pretty big a.

Also, how long does it take to fit a kinetico water softeners under a sink
