    Hi all,
    The drain outside my kitchen has got a bit of a blockage and I'm wondering the beset way to clear it.
    The drain is I think a standard size width, is about a foot deep and has a much narrower pipe running off at right-angles at the bottom towards the water company's manhole.
    There's about 5" of nasty-looking water currently filling the bottom of the drain. It currently doesn't fill up any further though - if you pour extra liquid in, you can hear it rushing into the manhole and the water level doesn't rise.

    Do you think this needs clearing? Or is it a trap for water?

    The reason I thought it needed clearing is that previously it really has been blocked and overflowing into the garden. Called out the water company to check if it was in their manhole end of things, and he cleared the blockage from the customer's side (i.e. our waste pipes). Once he'd done this, there was no water in the kitchen drain, but I hadn't checked between then and now.

    What do you think? Photos attached for set up. 20181104_114341.jpg 20181104_114335.jpg

    many thanks,
    Rob

    It’s dead easy, get a traditional mop make sure gulley is full of water and plunge away . I get thro many mops each year my Mrs goes ballistic cause I just leave the smelly ones and do not buy new ones. You will be surprised how much traction you can get with a traditional mop ...new types are rubbish
    You can do bogs, open manholes if not too deep and push poo etc along dead easy.
    Advice is to keep your mouth closed during this operation

    I recently bought a 15 metre long high pressure hose with drain cleaning attachment for my Karcher power washer. Cost me £19.99 on Amazon and blasts its way through blockages.

    Drain rods with the plunger attachment. Just make sure that the plunger has a metal thread, as i had one that was all rubber and it kept falling off into the gulley.

    As Rob said an old style mop makes for an excellent plunger/macerator (keep an old one handy all the time) failing that a set of rods isn't too expensive nowadays if it's a regular occurrence.

    It's quite a tight space though, 6" wide vertical hole and then a right angle into a pipe. Can drain rods fit in that that?

    Just poke the mop into the gulley with plenty of water added, the hydraulic action will get it without having the pokevthe mopin too far. If not work come back to us Rob Foster aka centralheatking
