Full product details
Read the full description
A 2-stage whole-house filter for town and mains water supplies, built on 2 Pentair 20" Jumbo housings with the cartridges already fitted.
Water passes through each stage in order: dual gradient sediment (20BDGD-PA) → KDF/GAC (20BKDF-GAC).
It comes assembled on a mounting bracket with a ball valve and a housing spanner. Fit it on the incoming line, restore pressure slowly, check every joint for leaks and flush the new cartridges before use.
Change cartridges when the flow drops noticeably or treatment falls off. How often depends on your water quality and use.
We're NZ owned in Te Rapa, Hamilton. If it's not right, we'll put it right.
