Good to see you going water fed. But with DI only?What is the TDS of your tap water? The HydroPower is a great tool. I run 17-20 TDS through it after RO and a 6 litre resin bag lasts forever. Anything over 70 TDS and you will be using a bag a week however. A bag every one to two days if tap water is over 300 TDS.
Tds is 50 here
Wow I’m jealous. TDS 370 in Berkshire. Have a great day 
Wow! That water must be just white where you are!?
As you know…high TDS for drinking water is not necessarily a bad thing.
e.g. Badoit Naturally Sparkling Mineral Water has a TDS average of 660!! Lots of Calcium and Bicarbonate which aid digestion and build the bones of hardworking window shinerz
Rainwater around here is appx 45 TDS but it quickly goes green in my rainwater harvesting system so would wreck my RO/DI without double sediment filtration as it arrives via my mossy roof!
