it may take a few minutes to purge air from system, open ro fausct and let it bleed air and run water with spurts. https://www.youtube.com/watch?v=-guPFrVEbgM

change membrane

if the adaptor isnt working replace it

Just unplug it for several minutes. You will need to reset the programming, hardness, time of day.

I believe as vague memory recalls their is a back wash or bypass of the ro filter system. Is the leak to the drain from a tube? or from the unit? IF you have a pump, the pressures are high entering the ro filter. If no pump they are no more than the city water. But given the age, plastic parts may be approaching their end of life. I Don't know what that is, but you might google this model and see if anyone is having these kind of problems.

Culligan does not sell repair parts for this. The red button will seal itself if you press it a few times while under pressure if you are handy I would replace it with a supportable unit Check HD or Lowe's

A TDS (total dissolved solids)meter is needed to test the Reverse Osmosis water and compare it to the feed water to determine how much TDS is being removed. Reverse osmosis membranes are designed to remove 80-95% of the TDS in your water supply.

For example: If your water has 500ppm of TDS the minimum TDS removal should be 400ppm leaving 100ppm. If the TDS from the Reverse Osmosis System drops to these levels it is time to change the Membrane.
Typically an RO system will consistently remove 90+% of TDS for many years. The normal lifespan for a membrane can be anywhere from 3-10 years. It all depends on the TDS of your water and your water usage. The higher the TDS the more frequently the membrane needs replacing. The other filters should be replaced every 6 months to keep the quality up and protect the membrane.
A TDS of 1000ppm compared to 100ppm is much more difficult remove to acceptable levels. I like to compare 1000TDS to taking muddy water, forcing it through a filter and getting drinking water. Where 100TDS may be more like a clear glass of water. Consequently a reverse osmosis system on high TDS will be less efficient, less gallons produced and filters will need to be changed more frequently to keep the quality and quantity up.

Depending on the model of your system here is a link to the manuals for Culligan Units.

Time = degree of difficulty from the lack of space it also = the amount of pipe preparation needed to fit the system so a reasonable amount of time would be 1 hour minimum to a max of 4 hours after which the person would be playing on your patience always get WRITTEN quotes first from several installers and accept the average

plastic line and fitting are a snap in item push the line in and at the same time press in the ring at the end of the fitting that releases the clamping action of the line make sure that the water is turned off and the pressure in the line is released
