I'm going to be repacing my mums sink as the plug hole surround has cracked.
We have bought a replacment tap aswell,this being a mono mixer tap.I had a quick look under the sink and there doesn't appear to be any obvious isolation points for the two pipes going to the tap.
if there isn't do i then have to drain the whole system through the taps after isolating the water to the house?
there is a water tank in the loft and tank in the airing cupboard.
any help is greatly appreciated!
