WaterMark Slim Design Twin Water Filter System | 20" x 2.5" (GT1-80)

Twin Whole House Water Filter System — 20" x 2.5" Slim Design, WaterMark Certified (GT1-80)

A slim twin whole-house system for places where a Big Blue will not fit. The 20" x 2.5" charcoal housings are UV resistant, so this one is happy mounted outside, and the taller cartridge gives you far more surface area and contact time than a standard 10" x 2.5" undersink filter.

Good for a small household, a granny flat, a cabin, or a tight laundry cupboard. It takes generic 20" x 2.5" cartridges, so you are never locked into one supplier for refills.

Choose your configuration

Whole-house housings are shipped to you empty, so you pick what goes in them. If you are not sure which way to go, call us — it is a two minute conversation.

• Complete — with cartridges ($253.50)
  System plus a sediment cartridge and a coconut carbon block. The sediment cartridge catches grit and rust before it reaches the carbon, and the carbon handles chlorine, taste and odour. This is the standard setup for mains water.
• Housing only ($194)
  The system, bracket and spanner. Choose this if you already know your cartridges or you are replacing a housing.

Filtering rain, tank or bore water? Filtration alone does not make untreated water safe to drink. Carbon does not kill bacteria, viruses or parasites. If the water is coming off a roof, a dam or a bore and it is going to be drunk, you want ultraviolet sanitation after the filters. Give us a call and we will size one to suit.

Installation

A whole-house system is plumbed into your mains, which is licensed work. We are the specialist side of Wahoo Plumbing, QBCC 15256568, working the Sunshine Coast since 1997 — so if you are between Caloundra and Noosa or all of Moreton Bay area, we can supply and install it properly. Anywhere else in Australia, we will ship it to you.

Servicing

• Replace cartridges every 6 to 12 months, depending on your water
• If your water carries a lot of sediment, the pre-filter will need changing more often than the carbon — that is normal, and it is doing its job
• Limit pressure: 500 kPa maximum
