W2B200 Installation, Operation and Maintenance.

According to the manufacturers, it’s possible to install this without a plumber. This is the case if you have some basic DIY knowledge and awareness of connection hoses, understand drains and overflow sets.

Whole House Softener Filter ComboThe good news is that the Water2Buy (aka the W2B200) is compatible with most heating systems in the UK and parts of Europe. This means that you should connect it with a cold water supply near a power source and near a waste overflow.

Just note that it is an electrical system based on salt. So you will need to make sure it’s near an electrical source and need softener salt.

The regeneration of your resin is controlled by a meter and takes about 30 minutes. In general, this is considered to be the most efficient way to provide water softening for 24 hours as this is based on the actual water yield instead of being a time-based system.

You can use all types of softening salt for regeneration (block, granular, pellet, tablet or table salt). The salt can easily be added through the wide and removable lid.

  1. Water2buy has unfairly increased replacement parts of their RO drinking units by 212% within one year of purchase. No prior notice before purchase of main unit. This has been acknowledged by Water2buy and they have promised to match pricing. But 3 months on and I am chasing them every week for codes to purchase filters are the original price.

    These units are supposed to last a long time and you require replacement parts for regular maintenance. I would advise everyone here to opt for a different company that you can trust and has adequate.

  2. I have had a w2b200 for over 7 years. I called them and they replaced the majority of moving parts because it would stop flushing. Take the back of the timer. I give the back a spray of wd40 in the mechanism on the left hand side and it fixed the problem. Next thing I had to do was clean the resin as the water was hard. I checked the cold water for harness and it appears good after the cleansing it with cleaner. I checked the hot water and it appears hard. Not sure why?

    1. Possibly, hot water tank still have some residual hard water in circulation, which will take some time to fully flush out.

  3. Having owned and sent back two WB800 models in less than three months, I’ve concluded that they aren’t all that great.

    The WB800 is the largest machine, at a listed 4000 litre capacity. I found it struggled to provide half of that. Interestingly W2B per person water useage is 120 litres per day, which is below the amount most other water softener companies use as a sizing guide. (The average is between 140 and 160 litres)

    I was also offered a W2B tap water filter system in return for leaving a review on Google – this practice may explain why the machines have such a high scoring review rate.

    The machine was overly complicated to setup, however W2B do have quite a good customer service department who are knowledgeable and helpful – it’s just a pity their machines suffer from poor performance.

    You are better off spending more for a Tapworks or BWT softener – these also have the added benefit of smart metering so they won’t run out of softened water in the middle of the day.

  4. Hi everyone, just had these installed in 2 identical flats by the same plumber. One unit has an overflow pipe sticking out the back and hanging around. The other does not. When I asked, the plumber said 1 is an upgraded model and he can’t tell until he opens the box. He said I just need to get an ice cream box for the overflow. I’ve paid him now, but he’s coming back to do some other jobs next week. Just wanted to get some views from people on this if you don’t mind. Should I push him to change the machine with the overflow pipe? Thanks

  5. We’ve had the W2B200 for a few years. It worked great in the first year or so, then stopped working. They say the unit needs regenerating every couple of years, or even every year, and sell a cleaning fluid that costs £45 for small bottle. That’s a complete rip-off considering most other brands do not require this. They won’t publish any info about what’s in the cleaning fluid, but my own research indicates that it could be based on citric acid, or similar.
    I instead, drained the unit, cleaned out all the deposits in the bottom (no idea why there was so much sludge – mainly white with a hint of brown), then ran the regen/rinse cycle with just water in the tank (no salt) 3 times, filled with salt and recycled once more. After that it was good for another year or so. Next time around I repeated, the above step but added a spoon of citric acid to the first regen/rinse cycle. Again the unit has been fine for about a year, until just this week when it’s again stopped producing soft water.
    On the whole it’s only just cheaper than other brands, but I wouldn’t recommend it to anyone.
    We had a Monarch unit before that was smaller, and ran for 5-6yrs without any issue or need for maintenance. The W2B200 also consumes a lot more salt than our previous unit.
    We Iive in East Anglia, so have very hard water, and a family of 5.

    1. I have my own system. Every system needs maintenance once a year especially where you have extremely hard water don’t be a stingy person and just maintain what you have

      1. I would say the WB200 will be struggling to provide consistent soft water for family of 5 in a hard water area. More so if you have power showers installed and are doing laundry for 5 people.

        Therein lies the problem of your high salt consumption. You need either the WB500 or 800

  6. Thanks Mr WG!

    Wefre curently assessing a whole house system for Osmio, Harveys Arc and Kinetico softeners. Do yiu have any pointers, as they all seem a little different in their approaches (we want drinking water too). Harveys is super expensive, but are they worth it?

  7. Hi
