TDS in new place is 580😀
For the sake of shower pump, washing machine etc, gonna get a water softener.
Anyone use one to supply their whole house?
I wish I had re-arranged my plumbing before I built my extension Og.
I would buy an automatic softener head but put it on a large vessel of 30 litres or more and regenerate manually. By using a large vessel you reduce the amount of re-generations of the resin. And with an automatic head, even used manually it's impossible to send salt through your RO which would ruin it. (I did this once with a manual softener hence why I bought an automatic. Expensive mistake!) For exactly how often to re-gen you'd need to look up the calculation or phone June at Gaps water. It would depend on how much water you're using. Buy a large brine tank so you can store plenty of Salt, say 3 x 25kg bags or you'll be storing the bags elsewhere. I have this up in my garage next to my static.
I wish I'd attached it to the whole house though, excluding kitchen drinking tap and garden taps. Too late for me to re-arrange now though as it's all in the ceilings and decorated. If I had done it though I wouldn't have the limescale marks around the toilet, shower etc. Not sure of the running costs with regards to salt though.
