Hello, first time poster, long time reader and DIYer here. TLDR Output from taps isn't great but cold water seems to be 1.5 Bar, where an I going wrong and what could improve things? I'm installing a new kitchen and bathroom in my 120yo flat but I am a bit unhappy with the flow from the taps. There is no gas so I have a gravity fed hot water tank in the loft with a header tank that sits approx 4m above floor level. I checked the flow / pressure (sorry I am sure they're not the same thing) by running tap for 6 seconds X 10 = Bar Kitchen Sink (15mm approx 6m run from 22mm main supply + stock narrow flexi tails to tap) Hot 0.40 Cold 0.65 Bathroom Sink (15mm under 1m run from 22mm main + stock narrow flexi tails to tap) Hot 0.35 Cold 0.60 Bath (22mm on main supply + 22m flexi no tap at present ) Hot N/A Cold 1.50 Getting 1.5bar on 22mm on a third floor flat doesn't sound terrible but the other taps come off the same pipe and are abysmal despite being rated for low pressure. Does anyone have suggestions on how to improve the output from the taps? I'm not certain a pump on the hot water supply solves the cold water problems but it's the economical option.
