How many pipes will go to the gas system boiler?

Does the pressure stay there or thereabouts if you open several cold water outlets? Certainly sounds ok

Is the water pipework quite noisy when running at full pelt, if that flow is coming through a 15mm pipe then I would expect it to be.

Hi Mardab

I am afraid that I can't tell at the moment. The only tap I have is the kitchen sink tap. All the other taps have been removed in readiness for the house to be refurbished. When the water is coming out of the kitchen tap in to the bucket or sink it is very noisy because of the speed, but I haven't noticed the pipe itself being noisy.

Thanks
Sally
