Sediment first, carbon second, UV last. On tank water that order matters more than anything else, because UV can't work through water that's still cloudy.
Where it goes: Between the tank pump and the house, filters first and the UV lamp last
Three stages doing three different jobs. Take one out and you have not saved money, you have removed the reason the other two work.
Drinking water. Tank water is good water that has run off a roof birds sit on. Sediment and carbon deal with what you can see and taste; the UV stage deals with the part you cannot.
What’s actually in Melbourne water, and what a filter does about it →
All three are the same idea — sediment, carbon and UV in one unit on the tank line. What changes is whether it lives behind an aluminium cover and how much cartridge is in it. Sizing is set at the quote, once we know the roof, the tank and how many people are on it.
Twin cartridges and the UV lamp on an open frame, with the controller on top. The one to put in a garage, a pump shed or anywhere the look of it isn't the point.
The same filtration behind a weather cover, for where the unit goes on an outside wall and you'd rather not be looking at cartridges.
The bigger covered unit, for a house pulling more water at once or a tank supply that loads cartridges faster than the E7 can keep up with.
Tell us the symptom — taste, smell, grit, dry skin, tank water — and we'll tell you which fitting addresses it. Including when the answer is a cheaper one.
Cartridges more often than a mains-fed system — how often depends on your roof and your tank, and we will give you a realistic interval after we have seen it. UV lamp annually. We will roll both into one visit if you would rather not track them.
Taste, smell, grit, cloudy water, dry skin, or just a general feeling that you'd rather not drink it straight. What you've noticed is the most useful diagnostic there is, and it usually points straight at which of the three is right.
~ 5 minMains or tank, what the pressure is doing, where the main comes in, and whether the cupboard under the sink has any room in it. On tank water we want to know about the roof and the tank as well, because that changes whether UV is warranted.

on handoverWhat the right unit costs depends on your water, your pressure and where it physically has to go. A “from $X” with none of that behind it is bait.

Plenty of people drink it untreated and always have. What treatment does is remove the variable: a roof is an open collection surface, and what lands on it changes with the season, the birds and the weather. Filtration plus UV takes that variability out, which matters most in households with young kids, elderly residents or anyone immune-compromised.
Because ultraviolet works by shining through the water, and it cannot shine through cloudiness. Sediment and organics shade the very things the lamp is meant to be killing. A UV lamp fitted ahead of the filters is a lamp doing very little, and it is a mistake we have been called out to correct.
Roughly annually. The important part is that a UV lamp keeps lighting up long after its output has dropped below the level that actually disinfects, so you cannot judge it by looking at it. Change it on a schedule, not on whether it is glowing.
No, and we will tell you that. If the tank does not feed anything anybody drinks or showers in, the case for UV largely disappears. A sediment filter to protect the pump and the cistern valves is usually as far as it is worth going.
Do those first. Keeping leaf litter and the first dirty run-off out of the tank is cheaper and more effective than filtering it out afterwards, and it makes your cartridges last a lot longer. Any filtration quote we give on tank water will mention what we saw at the tank and the gutters.
“Took the old gas Rinnai out, dropped in a Reclaim heat pump, sorted the VEU rebate so it came straight off the price. Bloke on the phone is the bloke on the tools, refreshing.”
“The VEU paperwork looked scary online. They filled it all in, I signed once at the quote and once on the day. Rebate was already in the price. Painless.”
“Quote number matched the invoice exactly. No 'we hit unexpected wiring' story at the end. Nice change.”
“Bedroom Mitsubishi went in before lunch. Neat pipework, brackets straight, temp checked before they left. Would use again for the lounge.”

“Answered the phone myself, quoted the job, showed up to install the job. That trail of trust doesn't exist with most of the bigger mobs anymore.”
“Hot water died on a Sunday with three kids in the house. Answered the phone, had a temp loaner running by lunch, new iStore in on Tuesday. That's service.”
“A week after install they rang to check the heat pump was running quiet and the app was set up. First tradie who's ever followed up after payment cleared.”

“Had three quotes for a ducted system. These guys were the only ones who actually crawled into the roof. Middle of the pack on price but installed cleaner than the others would have.”
“Full ducted retrofit over two days. When they left the roof cavity was tidier than they found it and the driveway had been swept. Small thing but it matters.”
“Walked me through the Milieu tablet, showed the wife how to use it, showed us the compliance cert. Ten minutes of teaching that other installers just skip.”
