    Hi

    Main sink on our Dakota blocked. Done normal stuff - suction & unblocking rod. Freed up something but still no joy. Is it possible to disconnect pipes under sink without doing more damage or should I leave it to a professional

    In short - any suggestions.

    Regards from Crystal Palace site.:cry:

    pipe blockage

    Hi Bill and Shirl,

    Sorry to hear about this and also a little worried for you as we have an Auto-trail and all waste pipes drop straight into a holding tank so no "U" bends to cause restrictions, bad side is you need to keep plugs in to stop fumes coming back.
    Shouldn`t be too difficult a job to break the joint at the bottom of the sink, hopefully the blockage isn`t in the holding tank.

    Rob and Chris.

    If there is a trap under the plughole, undo that and clean it out. On my van all the plastic rigid drain lines are pushfit. You can work your way along via the joints and clean as you go.

    Make sure you can reach each joint before you pull it apart!

    Hi Rob,

    To stop the smell, put a cup of biological washing powder in the sink and flush it down after every time you empty the tank, it will keep it fresh.

    holding tank

    Hi Peter,
    Thanks for that tip, we have just kept the plugs in todate, only had the truck since October and used it for a total of three weeks so still learning about it.

    Regards Rob and Chris.

    This blocked main sink is now officially doing my head in:cry:

    I have had the system to pieces & can confirm that the downpipe to the junction box (see photo) is clear. As is the junction box. I have stuck 4 metres of drain rod down towards the grey water tank - all clear.

    So I have determined that it is an 'air' problem.:Doh:

    Anyone have any bright ideas on how to solve this?:helpsos:

    We are driving down to Brighton tomorrow & I'm hoping that the great potholes of England will jolt it clear.:Rofl1: Lets hope so.

    blocked sink

    Have you tried opening the drain on the grey tank to atmosphere to see if water flows through, just to eliminate the air pressure thoughts, you could then try and blow air through the system before re-assemble.

    I had a similar problem on my Apache, rodding did no good so had to take the drain pipe off the tank, its just a jubilee clip.
    I found that a lot of slime had built up inside the tank and was blocking the entrance to it, i managed to scrape out around it and after that everything was flowing ok but to make sure i poured in a good drain cleaner and left for a few hours.
    That was 3 years ago and no problems since.

    I had the same problem on my Frontier Scout,none of the sinks including shower would drain properly. Until one week end I had forgotten to close the drain tap before using and the sinks flowed perfectly,subsequently I used a waste tank outside and problem was solved. What it does then make you consider is whats the use of the onboard waste tank,if you have to do this so the sinks will empty properly

    For cleaning my domestic ( home ) sink drains and in the motorhome I use Soda Crystals.

    Hot water down the sink, then about a cup full of soda crystals on the plughole then more *hot* water. I have a bathroom basin at home that gets 'sluggish' and this treatment fixes it; not necessarily immediately but gradually clears after a day or so. Used in the motorhome fairly regularly it keeps the pipes clean and, if a larger quantity is flushed into the waste tank and kept there while driving, it will clean out the tank of sludge and slime.

    I am sure it would help with your situation. It's about 80p per packet in supermarkets etc.
