Add an inline filter to fridge

Posted by mzdee (My Page) on

I have an older Admiral fridge that is working well. I need to add a filter (pre-dates built in inline filters). I have copper tubing from the water source and then some plastic tubing running up the back of the fridge. Am I correct in assuming that this is the water line? Where do I go from here once I have the filter. Online directions are a bitg confusing as they refer to both copper and plastic water lines.
I know I sound dumb, but I've accomplished quite a few things DIY with advice from these forums. Help me out. Please.

Thanks

RE: Add an inline filter to fridge

Why not cut the filter in on the incoming line?

1) Turn off the valve.
If you have access to the copper line that supplies the icemaker. Follow the copper line back, you should have a valve or some means of shutting off the icemaker. Typically it would be in the basement or under the kitchen sink.

2) Determine filter tappings / purchase adapters if necessary:
The tubing is probably 1/4" copper tubing, so you will need to adapt from the tappings on the filter to 1/4". I don't know what tappings your filter will have, lets just say 1/2" ips (female threads). You will need to get 1/2" male x 1/4" compression adapters and install them to the tappings.

3) Mount the filter.
I would not recommend leaving the weight of the filter on compression fittings. There should be some way of securing / mounting the filter. The filter will be directional (there will be an in and out). Be sure to mount in the direction of flow.

4) Plumbing connections.
Cut the copper tubing with a tubing cutter, and place the nut and ferrule on to the bare ends of the copper, and insert the copper into the adapters on the filter. You can apply some thread sealant to the connection if you want, but it isn't necessary. Slide the nut ferrule up to meet the adapter, make sure the copper doesn't slide out, and start the ferrule a few threads by hand. These fine thread connections are easily damaged if cross threaded. The secret is to make sure the tubing is lined up perfectly, straight and even with fitting. Tighten, turn on and test.

Start pulling some water out of the fridge...bingo bango...filter.
