Traditional taps think not # definitely not a traditional washer system nor fitting to conventional uk plumbing system will not accept a compression washer
Only good thing I got a full refund and return postage after a very lot of persistence
Watch out for the totally unreal responses when you complain like a small discount or a replacement not saying what it will be, they try their best not to give a refund
Even if the item cannot be fitted due to it being dented out of shape and a very bad design
