[concept]

Currently run a Merlin with Clarke CBM240 pump.

TDS in circa 360.

TDS after RO circa 30.

We use about 2-3000l per week.

Using loads of resin, even with twin DI.

What's the most suitable upgrade, utilising pump, as tap pressure is very low.

Cheers

Hf5 4040. You can use the pump you already have.

I have the 4040 with the same pump. 375 in 7 out.
