We have never used softeners at home despite having hard water in the region. This hasn't been a big issue as long as patients are decalcifying monthly. However since all our ROs are heat disinfected weekly I wonder if we are giving ourselves unneccessary work, Our heat membranes are lasting 2 to 2 1/2 years and we do get problems with drain valves chalking up and sticking. I am considering fitting softeners.
Can anyone recommend a reasonably priced, duplex softener with proven reliability, easy installation and small size ?
I was thinking Duplex- I see they offer those too. If anyone has experience of duplex softeners I would be interested. Also quite a few are non-electric which might be easier to install too.
I can see the point of having duplex in a main unit but do you not think it's overkill for a home situation? (extra cost, space etc...) If the softener went down the absolute worst is that you might need to soak the RO membrane in citric overnight to bring it back around and when all is said and done a new membrane is only a couple of hundred quid. Providing the resin doesn't get turned to mush by high chlorine levels then we've always found that a regularly regen'd softener is quite reliable.
Just a thought...

We use the Kinetico 2020c water softener supplied by the soft water company: www.thesoftwatercompany.com.
It's mechanical no electrics involved, it is a two tank system so one cylinder can backwash whilst the other is in operation and does not interrupt treatment. Also rather than using salt tablets or granules it uses blocks of salt (about the size of 1.5 house bricks end on) which our patients find a lot easier than bags of granules.
Yes I was looking at the Kinetico too. Quite expensive but the membranes for Aqua C Uno H is about 4 x the price of one for a Purite and we have very hard water so it may make sense in the long term as some heat membranes only seem to last about 2 1/2 - 3 years.
We've been using this 5L softener unit for a little while now and are slowly switching all our HHD patients over to it. Great for lifting and handling and very economical on it's water use, the valve is a bit noisy when doing the regen but not a big problem.
Fileder and Gaps water are supplying.
