Thinking of replacing valve in toilet cistern And was having a look in DIY stores.It is a bottom entry fitting and I notice the 'arm' on all the ones I see is PVC.Can anyone please tell me what the red removable gadget on the arm is for,also the arms are all too long for my cistern,Is there just one size? The fitting I have at present has a metal arm.Thanks for any advice on this
