    hi guys, the rads in my house are supplied with 10mm pipes coming from the floorboards, i am installing a towel rad which i would like to install by cutting the 10mm pipes about 50mm after they come out of the floorboard and replacing them with 15mm chrome ones, would this have any potential negative effect on the flow of water in the system?
    thanks

    No, it'll be fine. Just be aware that you can't use pushfit on chrome

    why's that? is the diameter bigger because of the chrome plating?

    The surface of chrome is very hard. Push fit need to dig into the copper a little, to hold firm.
