What we connect
- Basket strainers or a disposal flange
- Continuous waste or separate traps for double bowls
- Dishwasher drain with a raised loop or air gap
- Faucet supplies and new quarter-turn stops
- Filtered water tap or instant-hot tap if wanted
Working with your counter installer
Undermount sinks are glued and clipped to stone by the countertop company. We come after, once the adhesive has set, to fit the faucet, strainers and drain. A drop-in basin we can set in the counter ourselves.
The installation
- Check that the wall drain height suits the new sink depth; deep bowls sometimes need the stub-out lowered.
- Fit the faucet and strainers with the right sealant for the material.
- Build the trap assembly level, with a proper slope on the trap arm.
- Connect the dishwasher and disposal, then run each one while checking every joint.
Next steps

The short version
Tell-tale signs
- One tap trickles while the others run fine
- Lever spins loose or grinds to turn
- Wet hose bib or stain behind the washer box
- Spout drips with the lever fully closed
Kit on the van
- Headlamp and a foam pad for under-cabinet work
- Basin wrench and cartridge puller
- Quarter-turn stops and braided connectors
- Tubular trap kits in white plastic and chrome
How we go about it
- Turn the stops on slow and run hot then cold
- Dry every joint with paper and look again in ten minutes
- Shut both stops and open the tap to bleed it
- Strip the fixture and look at seats, seals and threads
Your questions, answered plainly
Do you install the countertop?
No; we handle plumbing. Your counter supplier templates and installs the stone.
Can I reuse my old faucet?
Often yes, provided it is sound and suits the holes in the new deck.
