What Gets Installed

Town Supply - From $2,495 Installed

A twin 20-inch system at the mains: a genuine Pentair gradient sediment stage, then a carbon stage for chlorine taste and odour. Every tap and shower in the house, not just one. Your first year's replacement cartridges are included free, and outdoor installs include the weatherproof cover. Then run it for 90 days - if the water is not noticeably better, we take the system out and refund you.

Tank or Roof Water - Quoted For Your Setup

Twin filtration for the sediment, then a UV steriliser for the bacteria, sized for a full household's flow. Rain washes whatever lands on your roof into your tank, which is why the UV stage is not optional. If a cheaper setup would be the wrong buy for your place, the quote says so.

Bore Water - Water Test First

Nobody can honestly price a bore system without knowing what is in the bore - anyone who quotes one sight unseen is guessing with your money. We organise the water test, then quote from the results.

HOW THE PRICE WORKS

One Written Price. Approved Before Anything Starts.

Your quote covers the standard install: system at the mains where your water enters, fitted by a licensed plumber. If your site needs more than standard - long pipe runs, awkward access - the plumber confirms any extra with you before starting, or you can take the supply-only price and use your own plumber. You approve every dollar before work begins. And the price is the price: no discounts, no "this week only".

WHO YOU'RE BUYING FROM

A real person. Not a faceless store.

No Brainer Water is NZ-owned and run by Mason, whose mobile sits at the top of every page - 021 709 370. If something's not right, you talk to the person responsible, not a ticket queue. Every number on this site traces to a published source, and every water report we send is built from your council's own testing data.

Frequently Asked Questions

The system ships free anywhere in New Zealand. Install we arrange through licensed local plumbers - your written quote states plainly whether your area gets the installed price or the supply-only price. Supply-only is a genuine option: the system arrives assembled with its bracket and spanner, and any plumber fits it at the mains in a couple of hours.
Town supply starts at $2,495 supplied and installed, with the first year's cartridges included and the weatherproof cover included on outdoor installs. Tank and bore setups are priced for the actual water and the actual site, which is what the written quote is for. The quote is itemised, free, and carries no obligation - plenty of people read it, think about it and come back a month later. It will still be the same price.
A licensed local plumber, arranged by us, working to the system's install spec. Plumbing compliance sits with the licensed installer, which is exactly where you want it. You approve the quote before anything is booked, and any site extra before it is done.
Because tank setups genuinely differ - flow rate, where the pump sits, indoor or outdoor mounting, cartridge sizing for how dirty the roof runs. A single sticker price for every tank in New Zealand would be wrong for most of them. Sixty seconds of detail gets you a real number instead.

JUST THE KITCHEN TAP?

If drinking water is the concern, start smaller.

The whole-house system is for chlorine, taste and sediment at every tap. Fluoride, PFAS and microplastics in your drinking water are a job for reverse osmosis - that is the Pentair ES60 at the kitchen tap. And if you just want the chlorine taste gone for now, the $179 Starter does that with no install.
