You need to clarify as to what type of water filter system. If the leak is in the tube itself, you can replace the whole tube or cut out the bad part and put a coupling there.

Culligan reverse osmosis filter system has stopped providing water from the sink mounted faucet attached to the system.

Since unfiltered water went through it for a couple days, I would guess you have mineral build up. If this is the case, be careful about trying to use it. There are certain products you can buy to unclog the pipes. Most will have you pour them down through the pipes connected to the polishing filter. If you can take the pipes apart, I suggest going pipe by pipe to see where the build up is.

My Amana french door/bottom freezer is leaking water. Did the procedure with hot water the drain in back of the freezer, although it seemed clear of ice. That didn't help. The leaking stops when I...

Two possibilities:
1. A cracked plastic tube. These will leak whenever there's a call for water - either the chilled water dispenser, or re-filling the icemaker tray (two seperate tubes). Pay particular attention to anywhere the tubes are clamped to the chassis; anywhere they're routed near or under the refrigeration unit; and near the solenoid valve - especially if there's a tight loop in the tube there.
2. A bad (leaking) connection where one of the tubes exits the water valve. Again, these will leak whenever the valve is activated.

Those plastic tubes don't last forever. I've replaced many of them for the same symptoms. They're known to simply deteriorate with age.
Manuf's make good money selling replacement tubing kits.

My culligan water filter is leaking, no idea why. Is there any way i can stop this?

Turn the water supply to filter system off, open the faucet to relieve the pressure.
It depends are where it is leaking form. If you just changed the filter it is either not on all way, the o-ring is pinched or missing, or the inlet line, outlet line (or both) were worked loose and are leaking.
Check the feed valve to the filter also. If it is a saddle/ piercing valve it may be leaking. After opening and closing these valves several times the "packing nut" may work loose and the valve leaks. Tighten this very slightly until leak stops. Here is a diagram of a saddle/piercing valve.


The packing nut is right below the T handle as in this picture. There is seal under the packing nut and this is where it can leak from when the nut works loose. AGAIN tighten this very slightly to stop the leak.

Leak from connection of Culligan under sink water purifier. Who sells replacement parts?

If the leak is coming from the "quick connect" fitting then either the tube is not pushed in all the way or it is loose. There are small "snap rings" that fit between the fitting and housing to hold them tight from John Guest. If the leaking line has a compression fitting they are available at any hardware
This on-line supplier has Culligan filters and John Guest fittings

My Culligan RO faucet has an ''air gap'' leak. How do I clear the clogged debris causing the water to constantly run? Culligan told me that the Faucet/Air gap is clogged. Need to dislodge the debris.

Normally when it leaks out the weep hole the drain line is plugged under the sink....turn off the ro to where it's not making water, disconnect the drain hose and flush it out....make sure the adapter that's connected to the drain pipe is still lined up with the hole if it was moved the water can't get to the drain.

Water leak

as for leaking underneath sounds as if the water line if cracked, or the connectore is loose, sounds like a simple repair, as far as the water squirting from back of frig, sounds like the fill tube leading into the ice maker itself has froen and the back pressure is causing it to leak. remvove the hose again and possible fro the inside usea long thin crew driver and try to clear the ice blockage, ( some tubes are removeable in which case you can run under the sink to thaw out
