The Plumm TW1-400 under sink water filtration system has the design and makings that allows it to provide superb performance, durability and convenience. If you are looking for a system that can deliver filtered cold water and unfiltered hot and cold water all from your kitchen mixer tap, then this is the water filter for you.

Our Plumm TW1-400 is designed to make sure that limescale, dirt and other unwanted water particles are reduced down to 1 micron. This filtration system also addresses water with a chlorine taste and odour issue, so can have clean, invigorating pure water. And because your health is of utmost important to us, we also designed our 400 series to reduce cysts such as Giardia and Cryptosporidium.

Like the Plumm TW2-400 undersink water filter system, this system uses a cartridge that has an approximately 38,000 litres capacity. It can provide a maximum flow of 10 Lpm (litres per minute). Our under sink filtration system can operate perfectly in temperatures ranging 2 to 58 degrees Celsius and can withstand pressures ranging from 200 to 680 kPa (kilopascal).

With a bold, angular spout, the TW1-400 three-way mixer tap is ideal for modern or contemporary kitchens,  and is manufactured from premium materials to exacting specifications.  This tap utilises a completely separate line for the filtered water, which means there is no cross-over of filtered and unfiltered water.

Our Plumm TW1-400 under sink water filtration system includes a diagonal spout 3-way mixer tap, a combination pressure limiter, a backflow and anti-water hammer valve, hot & cold braided pex hoses, and flexible ¼ inch poly tube.
