    we keep getting awful drain smells downstairs in our house, usually originating in the kitchen but now in the hall and sitting room also! The smells have intensified since installing a new kitchen sink. We thought that was the culprit as it seemed to happen when we put a lot of water down the drain or the dishwasher emptied which is also connected to the (****) Ikea trap! We’ve had a plumber come and try and adapt the trap but it’s still happening. We’ve also had Dinorod come and do a camera survey and they found nothing apart from a bend in our pipe under the kitchen, that he unblocked before Xmas but the smell is back already! We’re having our drains unblocked about every three months and it’s getting expensive! We are so careful about what goes down the sink as we’re paranoid about waste build up. I wipe out every pan and plate before washing and we have baskets in the plug hole to catch any remaining debris. Could it be a neighbour at fault and our drains are connected? We just can’t seem to identify the problem, anyone have any ideas?!

    have you checked the man hole recently is it clear and the roof vent that could be blocked by leafs and needs rodding
    that's why the smell isn't escaping from the drains and isn't flowing properly.

    Replace Ikea trap with a McAlpine one,far superior.

    Are the water seals being pulled out?

    Get a dry stick, run the kitchen tap for a few seconds. Put stick into plug hole down as far as it will go. Remove, mark and measure the wet part from the bottom. Leave the sink alone and do not use for three or four hours or until the smell appears.

    Use the same stick, insert again and see where teh level is. If it is lower, the the trap's water has been pulled through.

    Do you get any unititiated gurgling at the sink? If so, that could be a build up of gasses being pushed back through the seal.

    Thanks for the suggestions, I will try these out and hope it rectifies the problem!

    Lift the manhole's and check for blockages would be a good move as have had a similar blockage problem in the past.

    Where does the kitchen waste run? Have sometimes come across push fit fittings coming loose under the floorboards if this could be a possibility?
