    I wanted to ask for some help regarding a tap I have in my bathroom. It's become increasingly difficult to close (it does close) but over the years it's become more and more stubborn :)

    I would prefer to avoid replacing it especially if it's something as easy as just changing a washer etc

    Is this an easy fix and if so how would I fix it ?

    Thanks in advance
  2. Photo, please.

    If it's stiff, it won't be the 'washer' but more likely the spiral-thread inside it.

    I've sorted out a few stiff taps, and they are easy to fix - if you can dismantle them in situ (the worst part of the job).

    Photo will help.

    Possibly limescale build up within the tap body, a strip down and clean should sort it.

    Then add plumbers grease or Vaseline to the mechanism - keeps it all nicely lubed up and moving sweetly

    If this doesn’t sort it, then tap valves are worn. Gotta match correct size but easy and inexpensive job to do yourself

    You then literally have new taps so all good :)

    Ok so to clarify, I should remove tap head and then clean the spiral thread inside the tap add plumbers crease afterwards.

    if this doesn't work i need to replace tap valves.

    Do i need to drain down the system to do this ?

    You need to isolate the water to each tap yes, any isolating valves fitted underneath?

    If not then suggest you fit some first then you can turn the water to the rest of the property back on and take your time with the taps. Also suggest you start earlier rather than later in the day to give yourself maximum time. ;)

    On copper yes not so on plastic for a layman.
  13. Post a photo, movieman, and we should be able to guide you through it all.

    And silicone grease is probably the best lube to use when reassembling - it won't attack the O rings.

    A plumber's crease is a very different thing - a bit like builder's bum but cleaner. Don't post a photo of that for heaven's sake.

    Can someone explain to me what plumbers grease is please, Ive only been in the trade for 45 years and never come across it.
    Ive used graffite grease on gas taps, Ive used copper crest on screws, Ive used silicone grease on parts to be inserted with O rings, Ive used silicone spray on soil fittings. But plumbers grease has passed me by.

    Really. ???

  17. I wasn't aware of Plumber's Grease either, so looked it up thinking it would be better than silicone grease for this job. And then I read "Not for use on rubber or synthetic O rings..." :eek:

    The last one I did, I actually used nice thick 'Copper Ease' on the spiral thread part, and silicone grease on the rubber o-rings. Smoooooooth, man.

    (Surely Copper Ease wouldn't attack rubber since it's the stuff recommended for use on the backs of brake pads - where it's close to the rubber piston bellows?)
