Howdens Joinery HCB1721 Operating instructions

  • Hello! I'm a chat assistant and I've reviewed the installation instructions for the Howdens sink base unit. This document covers the assembly of both the 1000 and 800 sink base models, including pre-build steps, fitting cam studs, securing the unit to the wall, installing worktop and plumbing, and attaching panels. I understand the importance of using space saver plumbing kits, flexible tap connectors, and slotted pipework access holes. I'm ready to answer your questions about this product.
  • What type of plumbing kit should be used?
    What type of connectors are required for taps?
    Why should access holes for pipework be slotted?
