Rated 5 out of 5 by from Limescale inhibitor It works! Read the reviews, took advice from a plumber friend, all positive. In no time at all the improvement is very visible

Rated 1 out of 5 by from Not fit for purpose The coil wire plugs do not fit the sockets. Cheaply made and not fit for purpose. Returned for a refund. Not the first time I've had issues with Screwfix selling poorly manufactured products that don't work.

Rated 5 out of 5 by from Good product Looked at different options available rather than salt devices and this was worth the gamble. So far after a few days we are already noticing the difference. Due to the lime scale where we live the day after cleaning the taps with a heavy lime scale remover, they show lime scale returning, now any deposits of I guess chalk just wipes of. As others have stated, it does not make the water softer, but any help reducing lime scale is brilliant. Looking forward to seeing long term benefits. It was easy to fit, took the wife and me around ten mins.

Rated 3 out of 5 by from Cheaply made and overpriced I've seen one feedback that device didn't seem to do the trick for one person even if the led was working on the device and it might be caused by the cheap components used. One of my cables plugs was loose and probably wouldn't have a contact with a socket, so I opened device hoping I will be able to tighten sockets a bit (unfortunately this isn't possible, so I had to bend one of the metal plates inside the socket to make it tight). In my opinion, components used inside the device aren't even worth 10 pounds, so these devices are highly overpriced in my opinion. You can even judge this considering weight of the device. Is it working? I'm not sure yet, I installed it in addition to the inline electrolytic scale inhibitor which works 100% but I need to replace it every year or so. Would I buy it again? Probably yes but I would search for a cheaper alternatives.

Better than the lw2?

Can’t see this model on the bwt website only the LW2 wrapper one, both the same price and lw2 spec says 0.8 ltr/sec but can’t find anything for this one you offer. Which is best?

Static caravan

Can this be installed under a static caravan where the water enters the van or does it need to be installed internally?
Asked by: TallPaul73
We would recommend installing internally. The unit is designed to be placed in a dry area due to it needing a power supply.

lead pipe into copper- how far?

How far from the lead pipe (which is main coming into the house) can this be safely installed? after the stopcock I have 15mm copper all the way- can it be installed straight after stopcock or is there any specific safe distance from lead pipe required??
Asked by: artek
The product remains effective if fitted to copper pipe downstream of any existing lead work. There is no specific distance required.
