Upstairs Water Pressure

[Diamondnine]

Hello
I have used this forum before getting some good advice, now I need a little help.

I have just removed the bathroom suite from our house. The water to the bathroom comes via a 1” pipe built into the wall. This pipe splits, one line goes to the toilet cistern, the other comes down to 15mm copper pipe and feeds the cold taps for the bath and sink. It also supplies the boiler, electric shower, another toilet and another cold tap. These four being on an upper level in a loft conversion.

If I was to use one feed for the toilet, bath and sink in the main bathroom and the other feed for the boiler, electric shower, sink and toilet, would this help create a higher pressure of water to the conversion. I ask this because when a tap is turned on when a shower is being taken the water becomes cold. I assume it is something to do with water pressure. I know that water pressure decreases by so much per meter it climbs.

If you think it will make no difference then I shall blank one of the feeds off.

Regards

Andy

do you have a combi boiler, because this used to happen to me, the main water supply should go through the boiler first, and when you turn another tap on the boiler supply pressure drops and boiler will go out not supplying anymore hot water, you should have a cold and hot supply coming out of the boiler, if its a combi, and all taps toilets etc should be tapped off these.....

Pressure drops by about 0.3 Bar per storey.

The pressure is obviously dropping far enough to activate the low water pressure sensor in the shower.
