Plumbing on the Port Hills is its own discipline. Elevation, slope and post-earthquake ground movement create problems that flat-land plumbing simply does not have.
The higher up Cashmere a property sits, the lower the mains pressure arriving at it — which is why pressure complaints here are so often a supply issue rather than a fault inside the house, and why pump and pressure-vessel systems are common. Slope also changes drainage: gravity falls that work on the flat can scour or block on a steep run, and a number of hill properties still carry drainage disturbed by the 2010–11 earthquakes.
Call 03 377 5806. We cover Cashmere for both booked work and 24/7 emergencies, including nights and weekends.

“Johnny and the team at Inline have been such a pleasure to work with for our bathroom renovation. From the start they understood what we wanted and their approach to quality was excellent. Weekly check-ins and visits from Johnny kept us informed, and all our questions were quickly answered. We are very happy in our beautiful new bathroom.”
“Had to call out in the middle of the night and the guy that came out was amazing. He was friendly, knowledgeable and went above and beyond to sort what was going on. Highly recommend and will be using again, if needed (hopefully not in the middle of the night again though!!).”
“We had a new heat-pump hot water cylinder installed. The two young plumbers who came out were absolutely fantastic. They were polite, courteous and did really great work. Thanks to Inline and the team for making this process so easy and fast. Would highly recommend.”
“We have had a total bathroom renovation. The work ethic and professionalism was outstanding. Johnny, Sarah and the team were fantastic to deal with. Work schedule went absolutely to plan. Everyone involved were hard working and very respectful. So thrilled with the finished job — couldn't be better.”
“My new bathroom is beyond fabulous. Inline managed the whole process from start to finish, organising absolutely everything. Everyone at the firm from the initial design to the final sign-off by Council was super helpful and I got exactly what I wanted at the highest possible quality. I could not recommend them more highly.”
