Testing and reconnecting Kinetico 2020C Water Softener After 3+ Years Unused -DIY??

sujsuj

I’ve just realised that after living in my new place for more than three years, I still haven’t installed my water softener, which I brought over from my old house. I’m still in a hard-water area, and my partner has been reminding me about this for years—so I’ve finally decided to get it reconnected.

 It’s a Kinetico 2020C model (photos attached).

Before installing it, I want to test whether it still works properly, since it hasn’t been used for over three years. I’ve found instructions on how to test it, and I plan to do that over the weekend.

Now I’m trying to work out the best location for the installation. The only practical place seems to be the loft, next to the cold-water storage tank. The kitchen layout in this house changed over the last 40+ years—the original kitchen is now a drawing room, and the pipework there still feeds the tank.Because of that, I can’t install the softener under the current kitchen sink, as that pipework no longer connects to the tank.

I’ve added photos of the area around the tank.
Where would be the best place to position the softener in the loft once I’ve tested it?

Do I need to install it on an elevated platform, or can it simply sit on platform next to the tank?

Also, looking at the existing copper pipework, how would I create a bypass loop and take a feed to the softener? And how do I reconnect the softened water back into the copper line so that it supplies the tank and all downstream systems (e.g., hot-water cylinder, etc.)?

My other option is to leave the installation to an experienced plumber after I’ve finished testing the unit, instead of attempting the plumbing work myself.

Any advice would be greatly appreciated. Thanks very much

Any units in the drawing room where it could be located? Could there be?
I'm guessing these devices have - one cold mains inlet, one softened water outlet - which will supply the CWS, one drain, and one power supply?
Installation in the loft should be very doable, but you'd need to allow for the drain - I wonder if the 22mm overflow pipe will double as this?
Other than that, no, it doesn't need to be raised, as it's water mains-driven. But, you will need to protect it against frost, so ideally installed inside an insulated box - could be simple lift-off made from Celotex.
Bear in mind the potential consequences should you make a plumbing error, of course.
How often does it need resulting? And is lift access very good - safe platform, and bright lights?
The above is all assumption.

Also an overflow connection, which needs to run downwards from the connection point on the side of the body of the softener and exit somewhere the overflowing water will be seen.

The drain needs to be larger than 22mm - there has to be an 'air gap' between the exit of the drain pipe attached to the softener and any water contained in the installed drain run - to prevent backflow into the softener.  I wouldn't use anything less than 40mm for this, and wouldn't have it shared with anything else before getting to the stack or underground drainage.

If the unit develops a fault then the drain and overflow are the two things which prevent mains pressure/volume water escaping into the loft.... with obvious consequences for anything below.

The other issue is weight - I couldn't find a weight in the specs, but softeners tend to be heavy when empty, and considerably more heavy when the ion exchange tank(s) and brine reservior fill up with water.  Personally I wouldn't put one in a loft, but if there were no choice then I'd put it on a platform with a load-spreading structure underneath so the weight is over at least three rafters (and remembering the rafters already supporting the water tank may not have been designed for that purpose).

Is there an electric shower in the house?

A good idea to test it before installation, but after standing unused for a long time you'll also want to flush it through with lots of clean water.  So not just a functional test, but flushing for say an hour, leave to stand for 24 hours, then flush for a further hour.  You'll want to do the flushing shortly before putting the unit back into use... don't flush it and then leave it 6 months before you get round to doing the install.

The ion exchanger has a vast surface area for bacteria and other nasties to potentially grow on, so you'll want to make sure they have all gone.

Also, under no circumstances whatsover, put anything other than clean mains water into the unit to clean/flush it.  E.g. no bleach, disinfectant or washing up liquid should be going anywhere near the inside of the machine.

If you do plan to install the softener in your loft, bear in mind that you will need to top up the salt regularly.

Can you access the loft easily while carrying salt blocks or tablet salt?
