    Default Kohler sink waste O rings

    We have a Kohler sink which uses push in waste trap baskets. These seal when pushed in but the rubber O rings seal only last a few weeks and are expensive to buy. These are just ordinary O rings but the UK distributor charges £8.04 pence each !!!

    Any idea what I can use instead of the rip off British replacement ?

    I buy 'O' rings from China on ebay. All sizes available and cheap. Buy a bulk order for peanuts.

    This sort of thing: http://www.ebay.co.uk/itm/10-pcs-40m...kAAOSwj0NUfKd0

    Do a worldwide search and they'll come up. You may have to scour the listings a bit for the right size.

    Aldi and lidl often have boxes of them in their specials too... dirt cheap too. Depends on size though

    Oh my god! There's nothing wrong with the bidet is there?

    “Nothing discloses real character like the use of power. It is easy for the weak to be gentle. Most people can bear adversity. But if you wish to know what a man really is, give him power. This is the supreme test. It is the glory of Lincoln that, having almost absolute power, he never abused it, except on the side of mercy".

    “You see these dictators on their pedestals, surrounded by the bayonets of their soldiers and the truncheons of their police ... yet in their hearts there is unspoken fear. They are afraid of words and thoughts: words spoken abroad, thoughts stirring at home -- all the more powerful because forbidden -- terrify them. A little mouse of thought appears in the room, and even the mightiest potentates are thrown into panic.”

    "You don't have free will. You have the appearance of free will.”

    “There's a war out there, old friend. A world war. And it's not about who's got the most bullets. It's about who controls the information. What we see and hear, how we work, what we think... it's all about the information!”

    You can buy o ring in metre lengths for £1 (you could) from UK sellers.

    Try local "bearing man" or similar, they are probably shore hardness 70, try to get harder shore 90. They are probably nitrile.

    I wanted a small quantity of an unusual size that my local didn't stock, they'll be here tomorrow they said, and they were.

    They had to order 100, I really only wanted 10, but as they had to order a minimum order I said I would take 40 to help them to cover costs. I was shocked as the total payable was £5.70.

    Try your local store.

    A Micrometer, plenty on ebay, an example of a cheap one:

    You need to measure the diameter of the rubber the 'O' rings are made of and the overall diameter.

    If the 'O' rings are only lasting a few weeks then something is wrong with the design ?

    n

    It will be a standard size, so lay the o ring on a rule, and take the outside diameter and thickness of the ring. Then check the sizes on Google or your supplier.

    If you have a vernier gauge to measure, it may make things easier.
