Under-bench Hot water cylinder struggles for space

underbench_hot_water_cylinderTalk about limited space! When we arrived onsite we immediately knew we would be challenged with this exceptional under-bench hot water cylinder. Existing cylinder tank is 45 Liters and needs to be replaced (burst) with an equivalent size. The problem though is that the new Rheem hot water cylinder is much wider at 535mm in diameter. This is mainly due to the fact that newer hot water cylinders are now manufactured with more insulation making them “fatter”. after Disassembling and relocating all plumbing to the left hand side of the sink bench we gained further 150mm which made it possible to fit the new under bench cylinder and ensure all valves trains and wastes are installed as required by NZS 3500. What initially seemed impossible worked out to be a 4.5 hour installation with a very pleased client! Another successful job for hotwatercylinders.nz!

Low Pressure, Replacing like for like, some considerations…low_pressure_out_low_presure_in

This Cylinder came in last week, it was in a holiday house and the low pressure cylinder had burst leaking over the course of a few weeks and flooding a lounge. After assessing the job so many issues were ignored when the original plumber install this one causing many issues of our plumber to remedy. Things initially noticed was no cylinder seismic restraints, isolating vale on the inlet wasn’t installed and no drain at all was installed and the cylinder was in the middle of the house on a concrete slab.

No drain at all is a big no no when I comes to servicing. We ended up having to live change swap the inlet to the cylinder with a temporary drain to drain down the cylinder, making the job even more messy. Installing and fixing all these issues is FAR easier at the beginning before the original is installed rather than taking short cuts and making it harder for future Servicing. In the end we resolved all these issues and the job was a success, but a lot more difficult than it should have been so really if we all just put considerations in to our work before we start our jobs, we will all as a plumbing community be better off!
