A compact and attractive NSF labeled drinking water filter system Undersink Water Filter Installation. The UNDERSINK WATER FILTER SYSTEM empolys an ultra-filtration system including 4 specialty water filters housed in a compact case that can mount on the cabinet wall or rest on the cabinet floor. The water filters have “no tool” quick release fittings for easy filter replacement. The water filters included are NSF labeled and include a sediment filter, pre-carbon filter, ultra filter membrane and post carbon filter. In most residential installations the filters should be changed annually. If your water supply is high in sediment or chlorine, the pre filters ($18) should be changed semi-annually. The annual replacement filter set ($49) is also available for purchase on this website. The annual filter set includes all 4 system filters, the pre-filter set includes the sediment and pre-carbon filter.
The WATER GIZMO UF water filter system connects to a standard cold water supply using 1/4″ poly tubing and fitting (optional). The filtration system can be connected to a dedicated sink top faucet (included)
and / or the refrigerator supply for ice maker and cold water dispenser if so equipped. If connected to the refrigerator it replaces the manufacturers filter by using a bypass plug available from the refrigerator manufacturer. The refrigerator connection kit includes a T fitting, a 7/16″ refrigerator inlet fitting and 20 lineal feet of poly tubing.
System can be located anywhere including a heated basement, most often is installed inside the sink base cabinet. Most modern kitchen sinks in the US have a cold and hot shut off valve in the sink base cabinet. Typically the hot is left side and cold is right side and use a 3/8″ tube from the valve to the sink faucet. Connect a 1/4″ poly tube to the cold “3/8″ riser”.
There are 3 options for this connection.
1) The angle stop adapter is simple and best used if your cold water riser is plastic. The riser nut is loosened and the angle stop adapter threads onto the angle stop valve and the riser nut threads onto the top of the angle stop adapter.
If your refrigerator is connected to a water supply under the sink, disconnect the refrigerator and use the supply for the water filter system. Then connect the refrigerator with filtered water form the system outlet using a T.
2) The plastic riser can be cut and a 3/8 x 3/8 x 1/4″ T can be installed between the 2 cut ends of the riser. This is easy with a plastic riser, but more difficult with a metal riser, but not impossible.
3) Install a 1/4″ piercing valve (saddle valve) onto the metal riser. This is the easiest connection for the metal riser, but usually reduces the flow somewhat. If you have good water pressure, it should work fine. I prefer method 1 or 2.
Connect the 1/4: poly tubing to the inlet of the system and the cold water connection. The inlet of the system can be identified by the tube that enters the sediment filter and has a shut off valve installed.
The other fitting on the system is the outlet and that has a 1/4: tube that attaches to the dedicated faucet on the sink top. The faucet is included with your purchase, and you may have a spare hole in your sink, if not you will need to drill a 1/2″ hole in your sink to accept the faucet base.
If you are connecting your refrigerator / ice maker, install a 1/4″ T somewhere in the outlet tubing and run a 1/4: poly tube from the T to the rear of the refrigerator. Find the easiest route. If your refrigerator is currently connected to a water supply located under the sink; disconnect the tube from it’s connection and insert that tube into the 1/4″ T you installed. This is the easiest. You could use the existing supply connection to supply your water filter system and disregard the 1st cold water connection.
