Cashmere rises up the north side of the Port Hills above the southern end of Colombo Street, and its elevated sections look out over the flat city. Homes were first built here in the 1890s, and the tram line that ran until 1954 helped the suburb build a reputation as one of the country's more well-to-do suburbs. Hillside properties sit on ground prone to rockfall, cliff collapse and landslips. Most homes in Cashmere run on an electric cylinder in a cupboard, the garage or the roof space. We remove the old unit, fit the new one with fresh valves and connections, and test it before we leave.
Cashmere hillside homes: pressure, access and restraint for a new cylinder
Cashmere's homes climb the north face of the Port Hills, and the higher sections sit well above the city. Christchurch City Council supplies hill suburbs from reservoirs or tanks to keep pressure even, but the pressure arriving at a house can still vary with its height, so we test it before fitting a new cylinder and set up the pressure limiting and relief valves to suit.
Hundreds of Cashmere homes were damaged by rockfall, landslides and ground cracking in 2010 and 2011, and GNS identified 36 areas of mass movement. Many homes were repaired, and the cylinder may have been reconnected as part of that work. We strap the new cylinder firmly to the framing and use flexible connections where the maker requires them, which is the right approach on ground that has moved. Elevated homes from the 1890s onward can also have cylinders in awkward places after extensions, such as under stairs or on a lower level.
Delivery takes planning. Steep driveways and paths mean we check access when we quote, and on very steep sites we bring a trolley and extra hands. Where a home has bathrooms on more than one level, we size the cylinder for showers running at the same time. The Port Hills fires of 2017 and 2024 burned close to homes on this side of the hills, and a home rebuilt or renovated since then is a natural point to rethink where the cylinder sits and how it is heated.
Local tip: If water pressure is weak on the top floor of your Cashmere home, mention it at the quote, because it affects which cylinder and valves we recommend.
