    Upgrading water supply to improve flow to property | …

    10/2/2016· - 15mm is my best guess based on me being able to see approx 5mm of pipe before the stopcock due to the screed under the sink in my utility room. It could be that it''s fatter, but 4bar and only 18L/m tells me it''s probably a pretty small pipe. 22mm might be standard now (I think new builds probably have more than this), but it''s a 1960 house.

    The expansion pipe should have its outlet overhanging into the cold water supply pipes but not below the lip of the pipes. The cold water pipes should have an overflow pipe leading to a safe spot outside that is visible in case the expansion runs too much or the ball valve fails and doesn’t shut off.

    We then planned on connecting it to a new stop tap which reduced the width to 15mm so that this can then go into the water meter already installed and exit in a 15mm pipe as well. But we are now replacing the boiler, and the required model needs a 22mm water pipe supply.
