Question about Culligan Under Sink Water Filter

1 Answer

My undersink RO system leaks at all four tube connections on the manifold. I inspected the fittings and the o rings are fine. I inspected the tubes and I cut off the ends of each piece to make sure that they weren't scuffed. The system is a Culligan ac-30 good water machine.

The quick connect fittings need to be fully seated or when pressure is applied they will leak. If the feed is pressure is high to the RO I have seen this occur also. JG John Guest makes a small locking clip that goes on these fittings to hold them tight. Here is a link to JG which shows this application.

    Leak at one of the fittings on my Culligan RO system


    Too much pressure in holding tank will not cause leaks in the RO unit. All too much pressure in tank will do is cause low or no product water in RO tank. Older Culligan RO systems (H8, H83, H5) had fittings that used metal locking washers and these can cut the RO line after the RO has been moved around while changing filters. Newer styles (AC30, Water Tower) use quick connect fittings and the RO line may work loose after filter changes and system being moved around under sink.
    Turn the incoming water off to RO, turn the water off on RO tank, open the RO faucet to relieve pressure and pull the line off feeding the RO tank, inspect (you may want to cut off a small portion of the line at the filter) check the o-ring and re-install.

    Got a 2001 ford focus showing engine code PO171. was wondering what it was for or if there was more than one part that could lead to same code?


    Any introduction of unmetered air (basically a leak) after the MAF sensor in the air ducting will cause the engine to run lean. You need to check very thoroughly and methodically every tube that connects with the inlet manifold plenum for signs of leaks like cracks and loose joints. Take your time inspecting everything in detail, be quite rough and don't be afraid to twist them around to look at the underside - the leak can be so small that it hard to believe that it is the cause. Also check that the evaporative purge valve is closed when revs are low and the engine is cold. A quick method is to pinch each tube closed in turn for about 10 seconds and listen for any change in engine performance. Check the tube that leads to the brake servo unit for tight fitting seals. If all tubes look good, spray WD40 or carrb choke cleaner around where the the Injectors fit into the manifold and also around the manifold gasket where meets the engine block. A leak may be revealed as a rise in revs as the spray is sucked in an temporarily enriches the air fuel mix. If no leaks are found then check the fuel pressure regulator for correct function.

    How do you replace the egr valve in a 1997 chrysler concorde lx


    Chrysler Concorde 1993-1997 3.5L MFI 6cyl
    Exhaust Gas Recirculation System
    Operation

    This system reduces the amount of oxides of nitrogen (NO x ) in the exhaust by allowing a predetermined amount of exhaust gases to recirculate and dilute the incoming fuel/air mixture. The diluted air/fuel mixture reduces peak flame temperature during combustion, which in turn inhibits the production of Nitrogen oxides. The principal components of the system are:
    - EGR tube (connects a passage in the intake manifold to the exhaust manifold)
    - EGR valve
    - Electronic EGR Transducer
    - Vacuum hoses


    Component and System Testing
    1. Check the condition of all of the EGR system hoses and tubes for leaks, hardening or kinks on the rubber hoses. Repair and correct these conditions before proceeding any testing.
    2. Be sure that the hoses at both of the EGR valve and EGR valve control are connected to the proper fittings.
    3. Be sure the electrical connector is firmly attached at the valve control.
    4. To check the EGR system operation, connect the DRB III scan tool or equivalent to the 16-way data link connector. The data link connector is located on the lower edge of the instrument panel near the steering column. Follow the scan tool instructions.
    5. After checking the system with the DRB III scan tool, proceed to the EGR valve leak and control tests, then repair as necessary.

    6. Remove the EGR valve and transducer.
    7. Clean both gasket surfaces and check for any signs of leakage or cracks. Replace the components if any such damage is found or if the valve fails the tests.

    To install:
    1. Loosely install the EGR valve and a new gasket onto the cylinder head.
    2. Using a new gasket, attach the EGR tube to the valve and tighten the screws to 95 inch lbs. (11 Nm).
    3. Tighten the EGR tube to the intake manifold plenum screws to 16 ft. lbs. (22 Nm).
    4. Tighten the EGR valve to the cylinder head screws to 16 ft. lbs. (22 Nm).

    Water Supply Line for Ice maker and Water dispenser is leaking.


    Hi, The fitting either needs tightened or changed. Is this a brass or plastic fitting?
    If the supply line is still ok and not brittle, you can go to your local hardware store and get the new fitting parts. If it is brass, be sure and get the brass insert that goes inside the tubing as well as the compression ring.
    Please let me know if I can assist you further.

    Water leak at filter


    I had this with a Kitchenaid Superba and wanted to get rid of the filter holder assembly entirely as I have an undersink unit which serves the fridge. I removed the plastic line (nut) at the back of the fridge (which led to the filter holder at the front) where the flexible copper tubing inserted (this was a 3/8' compression fitting-plastic) and also the returning line (1/4" copper compression nut on a plastic line) at the manifold (again in the back of the fridge) where it gets split between the water line and the ice line. I then just connected the 1/4" flexible copper directly to the manifold (1/4" nut, compression sleeve, male-male connector) using a pre-made 1/4" flexible compression line. Sounds complicated but after seeing how the water routes it was fairly quick work.
