I've been to see a customer who wants better water pressure, he wants a shower cabin, he's on gravity now and gets about 6 litres out of his mixer taps on the hot side. &nbsp;Can fit a big combi for the flow rate, he is getting about 16litres a minute out of the cold. &nbsp;However I spoke to megaflop, they said it's not enough for unvented. &nbsp;Any advice?<br><br>thanks everyone.
