Why families switch

What changes when you filter. And what keeps happening if you don't.

✨

Glowing skin

On the contrary

Chloramine stays stripping skin of its natural oils, showing up as dryness, irritation and flare-ups.

💆

Softer hair

On the contrary

Mineral scale keeps building up in every wash, leaving hair dry, dull and harder to manage.

💧

Better hydration

On the contrary

Chlorine taste keeps putting people off drinking enough water straight from the tap.

🛡️

Protect your plumbing

On the contrary

Rust and grit keep wearing down pipes and hot-water systems, shortening their working life.

No nonsense sales tricks about water quality, no 'can only offer you this price for the next week'.

I looked at many companies, all of them were pushy sales people. When Mohammed reached out I was glad to know he's a plumber.

He personally spent time with us at no extra charge to determine what best suited our needs. Once sorted the unit was fitted next day.

Demand Filtration plumber installing a whole-home filtration unit
From the founders

Hi, we're Mo and Ali — brothers, and both licensed water quality plumbers.

We started Demand after one too many callouts to fix a job someone else had oversold: a unit too small for the house, a membrane that couldn't handle the local water, sold by someone who'd never have to install it or answer for it later.

Most whole-home filters stop at chlorine and sediment. We didn't think that was good enough.

So we built Demand FullGuard, and made one rule: nobody sells it who isn't qualified to fit it.

That's still true today. When you talk to us, you're talking to the person who tests your water, specs your system and installs it himself.

We run FullGuard on our own homes. Our families bathe in that water.

If you want a straight, specialist opinion on your water, book the test. We'll come out and show you exactly what's in it.

Introducing Demand FullGuard

Five times finer than a standard whole-home filter. And it takes fluoride out at the mains.

Water enters the house. It passes through FullGuard before it reaches a single tap. Here's what gets caught on the way.

  • Sedimentrust, dirt, grit from the mains
  • Carbonchlorine, chloramine, taste and smell
  • Fine filtrationfive times finer than a standard whole-home filter
  • Fluoride removaltaken out at the mains, every tap in the house, not just one under the sink

Finer filter, slower shower?

No. FullGuard is specced to your home's flow rate, so a finer filter doesn't mean weaker pressure.

And because a licensed water quality plumber specs it, FullGuard is built for your house. Membrane, size, housing, colour and location are chosen for you, not pulled off a shelf.

Who fits it

One licensed water quality plumber, start to finish.

Most companies quote with a sales rep and install with a subcontractor. We don't. He handles every step, which is how we can promise the speed and lock the price.

Test & advice

He tests your water in front of you, then tells you what you need. And what you don't.

Written price

You get a price on the day. Written down. It covers everything, because he's the one doing the work.

Install within 24 hours

Same plumber. Two to three hours on site. Clean, tidy, walked through before he leaves.

Aftercare

Filter due? Question later on? You call the plumber who installed it. Not a call centre.

When the same licensed water quality plumber owns every step, there's nobody to blame and nothing to renegotiate.

Book My Free Water Test
Our price guarantee

If the price changes after your deposit, you get the deposit back and the install is free.

Quoted on the day. Installed within 24 hours. Same number on both.

That's not a slogan. It's the deal. We can make that promise because the plumber who quotes is the plumber who installs. He has already seen your house. There is nothing left to discover on the day.

Locked in, in writing

Every whole-home install, fully installed, includes:

  • The unit, specced for your home
  • Full installation by a licensed plumber
  • Pressure testing on every tap
  • 10-year manufacturer warranty

Cheaper units

Filter far less finely, carry a two-year warranty and use cheap housings.

Demand Filtration

We sit in the middle, and the number doesn't move.

Dearer units

Some cost a small fortune every year just in replacement filters.

A note on payment

We don't do finance, and we don't think a weekly-repayment pitch belongs in your kitchen. If you're a good fit and need to spread it, 50% on the day and the rest over four weeks.

What happens when you book

Three steps. No pitch.

Book the test

Fill in the short form. A plumber calls you back to confirm a time that suits.

The plumber comes out

He tests your water in front of you. Gives you a written price on the day. No pressure to decide.

Installed within 24 hrs

Same plumber, two to three hours. Filtered water from every tap before he leaves.

One thing we ask

Before we come out, read our reviews. Sit down with your partner and go through them. Customers have left photos of units, colours, install spots and how it's going a year on. It'll answer half your questions and give you better ones to ask us.

Your Free In-Home Water Test includes

  • Chlorine and chloramine test done in front of you
  • Chemical-by-chemical walkthrough of your tap water
  • Assessment of your pipes, pressure and best install location
  • A tailored system recommendation
  • A written, same-day price backed by the guarantee

Why free? Because we only send a plumber when the water test makes sense for you. If a whole-home system isn't right, we'll say so and point you to what is.

Straight answers

The questions people ask before they book

It is good, by Australian standards. Most people come to us because of chlorine taste and smell, dry skin, kids with eczema, or fluoride. If none of that bothers you, you probably don't need us. We'll tell you that on the phone.

Yes. Parts of the west and outer east are on chloramine, not plain chlorine. Standard carbon doesn't handle it well. A plumber checks which zone you're in and specs the unit accordingly.

A properly sized unit shouldn't be noticeable. We check your pressure before we quote and test every tap after install.

Usually at the mains, outside. We can colour-match the housing or tuck it away. The plumber will show you options on the day.

Standard-size cartridges, replaced roughly once a year. You're not locked to us for them.

No. If you're a good fit and need to spread the cost, 50% on the day and the balance over four weeks.

Two to three hours, usually within 24 hours of your go-ahead.

Townhouses, yes. Apartments are a different job; call us and we'll tell you honestly if it's worth it.
