so im better off going with the 3/4 inch line, than sticking with the 1/2? also if i put up a tank on my flat roof, which is 7m high and put up a 240 gallon tank, would i get greater pressure from it, than from the mains outside (please note that the water from the tank would have to have the pressure to go down to ground level and then back up a floor. Any help greatly appreciated as the job is going to get underway by saturday and my family havent beeen able to take a shower in almost a year as there isnt even the pressure at the moment to raise the water up a floor, that is why we got the new connection which we have to hook up. The old line that came in from the back is over a 100 years old and is only 1/2 inch yet it serves a row of houses! In Ireland regulations stipulate you have to have a storage tank, at the moment we have a direct system (ie we rely on the pipe pressure to feed the whole system. I look forward to your replies
