Product Description
Reverse Osmosis System Plus Remineraliser with a Pump
A small percentage of UK households don't have sufficient pressure to run a normal non-pumped Reverse Osmosis system.
Pressure is measured in BAR.
1 Bar is the force needed to raise water through pipes up to a height of 10 meters.
1 Bar pressure would fill a 1 litre jug in about 7 seconds (via standard 15mm pipes).
Non pumped RO machines need 3 Bar operating pressure - but this is playing it safe.
To have a Reverse Osmosis filter system you simply need to make sure you have a reasonably healthy flow rate (which is the same thing as reasonable pressure) in your property - or at least from the pipe you'll be taking the water supply from.
This is usually the same pipe that goes into your kitchen sink cold water tap. (Bear in mind that the pressure might be too low at the top of your house while it's OK in the kitchen).
You don't have to measure your BAR. Instead a simple way to measure your water pressure is to turn your kitchen cold water tap on full.
If the flow seems vigorous and you get small splashes while standing near the sink then you probably have good enough pressure. (If you're getting splashed standing a few feet away then that is high pressure!).
Think You Might Have Low Pressure?
Most property owners already have a sense of whether their pressure is low.
Reverse Osmosis filters need reasonable water pressure to work.
If you suspect you have low pressure then it is best to opt for a pumped RO system straight away.
This is becauseretro-fitting a small pump to a system that's already fitted is not as easy as you'd think.
Getting it right is quite complex - if you want to do it safely!
For example; you need to have a setup whereby the pump turns on/off at the correct times ie has the right types of switches.
It all needs to be properly wired up in a specific way or it can damage the RO filter - and could even cause a fire!)
It's not as simple as retro-fitting an aquarium type pump.
This is why any good water filter supplier would say that, basically, if you buy a non-pumped RO system and then realise you need a pump, it is better to simply remove it - hopefully negotiate a refund from your seller - and buy an RO already fitted with a pump.

As you may already know, Reverse Osmosis filters are usually expensive. You can easily pay £400 plus.
However, even though our filters are of a higher quality than many on the market, we are offering them to you here at a Special Offer price of £345 - See Today's Special Offer at the top of the screen.
Why are These Cheaper than Others on the Market?
Well for a start some people are simply overcharging. They are using the classic sales approach that "if it's expensive it must be good".
Yes, Reverse Osmosis is good. But it doesn't need to be that expensive.
Plus we only sell on the internet. Unlike other retailers, we don't have to pay for expensive shop rents and rates. And we don't add unnecessary "stages" to our RO systems.
Replacing the Filters
Like all water filters, you will need to replace the filters on the system periodically to ensure maximum performance.
The five main filter cartridges need to be changed every six months (Cost £47).
We will send you a reminder every 6 months to change these filters.

Five filters needs to be replaced every: 6 Months.
Replacement code: FRO-PMP
The membrane filter needs replacing every 2 - 3 years on average *depending on local water conditions
Replacement code: MEM-RO
Running costs per days - approx: 35p
Replacement time / difficulty: Easy; takes a few minutes
Replacement notes:
Your pre filter cartridges and membrane “drop in” to a housing. Tubing "push-fits" into your post filter cartridges. You replace the cartridges NOT the whole housings.
We send you a reminder when it’s time to change the cartridges.

Capacity / Production Rate - Gallons Per Day (GPD) 75 Gals
Feed temp (Degrees C) 4 to 29
Weight 19kg
Dimensions
RO unit: 49.5cm High x 37.2cm wide x 19.5cm deep
Storage vessel is 40cm High x 27cm wide
The 12 Litre Tank / Storage Vessel (Freestanding, connected to RO unit by tube, can be placed several yards away - simply ask us for some extra tubing).
The unit should be fed by a water supply that is potable i.e. drinkable.
Please note that Reverse Osmosis is a complex process requiring reliable equipment performing under high pressure. Always know where your water main stopcock is located in the unlikely event of leaks.
The filter system doesn't have to be at a level below the tap and neither does the tank as long as it's not a gravity fed system.
This model will produce 50 GPD ie its "production rate" is 75 gallons per day.
(This assumes perfect conditions ie clean water at the right temperature and that incoming pressure is good).
But when considering how much water is produced by any Reverse Osmosis filter, the most important factor is the size of your RO tank.
This is because your system feeds the tank then stops when it's full.
Here's how it works: When you draw water from your RO you are taking water from the tank. As the tank empties the system refills it at the "production rate" (ie 50 GPD) up to the tank's capacity.
Now, in addition to this, you have to consider that the tank's size is based on the actual physical dimension and not the amount of water it contains.
You have to also take into account the internal bladder that holds the water inside of the tank.
For example, the bladder inside this unit's nominal 12 litre tank will actually hold between 5 to 9 litres of water. If you draw all the water out of the tank it will take anywhere from half an hour to 4 hours to fill up again - depending on incoming water pressure.
Therefore the amount of water this size produces is 5 to 9 litres per average of 2 hours - on a stop/start basis. (Note that you only have to wait for more water if you fully drain the tank in one go. In our experience this happens very rarely with normal domestic usage).
Other typical tank sizes and the actual water they hold are:
18L nominal tank size: Holds 12 to 15 Litres
40L nominal tank size: Holds 23 to 28 Litres

The simplest way to check your water pressure is to turn your cold water tap in the kitchen on full. Stand a few feet away. If you are being splashed with at least a few droplets then your pressure should be high enough.
If this is not happening, your local water supplier should be able to tell you what your water pressure is and whether it is likely to drop below 40 psi at any time.
The Unit is NOT designed to filter HOT water. It should only filter water at ambient temperature. (Feed temp = 4 to 29 degrees C).
However please note that our Reverse Osmosis units are often used to supply filtered water to hot/boiling water taps and other systems where the temperature is changed. That is fine. But the system itself should not filter hot water.
What are the Materials Inside the Reverse Osmosis Tanks?
Some people are concerned about the materials the RO tanks are made from and how it might impact their purified water.
This is understandable:
Who wants to filter their water carefully only for it to be somehow polluted in the storage vessel while waiting to be used!
(Just to be clear: RO filtration is a highly effective but slow process. Rather than you waiting for the filter to produce enough water for you, the system purifies the water slowly and fills up the storage vessel / tank. When you turn on the RO drinking tap there's several litres of filtered water waiting for you. The system then refills the tank with whatever you took out).
Our RO tanks / storage vessels are made from highly durable steel. The water doesn't touch this - which is a good thing or the highly purified water could cause the metal to release chromium oxide into the water!
Instead, the water is stored inside an airtight rubber bladder / diaphragm.
This is made from "butyl rubber" which is lined with polypropylene - a commonly used food grade plastic (see "Hazard data" below).
All these materials are industry standard. We have never come across and other type of materials for Reverse Osmosis storage tanks - and, collectively, we've been in water filtration for over 50 years.
(Bear in mind that after leaving the tank the water is purified even further by the post filters).
Polypropylene Hazard Data:
No negative health effects and symptoms.
No negative physical and chemical effects.
No hazard for environment.

Such an improvement over unfiltered water. Losing microplastics, scale, chlorine and all the other nasties that can work their way in is just a bit of piece of mind for me in relation to my kids.
– Nick Love
I've had the filter installed for 1 month now and the water tastes loads better and no more smell of chemicals, just clean fresh filtered water I'd say it's the best water I've ever had.
– Neil Bradfield
“My filter fits easy and I am happy. We weigh the old filter when it is removed, filled with gunge which never got into our bodies with this filter. It’s quite frightening. My filter is worth every penny!
