- Plumbing help!! – water ballcock not closing valve in cold water tank
if you raise the ball manually does the inlet valve stay open or does it close (i.e. can you shut off the intake by lifting the arm?)
if yes, then yes, you can possibly solve it by bending the arm, but if the valve seat is mucky and you need to lift the arm with some force to close it, then you might nor be able to rely on the flotation of the ball to shut it off when you’re not therePosted 6 years agorickmeisterSubscriber
Check that the valve will actually close and stop the water flow if you lift it up, if not, the valve is fekked… but yes, gentle bending of the arm downwards should do it…. try to not stress the valve in the tank… I was clumsy and broke the pin holding the ballcock arm… nice and easy does it.Posted 6 years agosweepyMember
Im not a plumber, but IME it doesnt normally come out that fast, so before touching anything Id make sure I knew where to turn the water off.Posted 6 years ago
Then id gently lift the arm to see if that stopped the flow, if it did id look for a threaded adjuster on the valve/arm. If that didnt work I might bend the arm down.
please see photo below – I’ve put a red square around what looks to be some kind of ‘in-line’ valve (sorry I don’t know the correct term) which seems to be on the pip letting the water in?
If I close that will I close problems elsewhere? Just for overonight till I can get a plumber out?

get rid of about half the water in the cistern by opening a hot tap..
with the isolation valve still closed. undo the brass nut that secures the pipe to the valve. ( a little very little water may escape) be cautious you need to keep the little fibre washer thats in the end of the brass nut intact.
remove the plastic nut on the outside of the tank. remove the valve and ball. fit new ball to new valve tighten it nicely but dont overtighten.
take one of the white plastic nuts off the new vale and adjust the second so that it is approx. the same distance in as on the original valve..
thread the valve through the hole in the cistern put the second plastic nut on to the outside of the tank so that the new valve is secure..
re attach the brass nut ( and red fibre washer ) all secure?
open the isolation valve a qtr turn, if the brass nut leaks ( thats the only place it can/ will give it a little tweak ( your fastening a little nut not securing the forth road bridge!)
check agian for leaks and that the ball valve closes whan the cistern is full..all okay?
go downstairs and boast of your handymaness to any passing honeys..smoothchickenSubscriber
Excellent it’s not just me that has Sunday night (all the shops are now closed) plumbing issues! Managed to screw through a heating pipe in two places teatime yesterday water ished through the ceiling about an hour later. Had to drain the heating, scrabble round in the loft, rip up floorboards, managed to stop the leak in the 2 1/2 hours it took British Gas EMERGENCY service engineer to call back, fail. Will now be waiting all day no doubt for plumber to turn up. Schoolboy error 😳 BTW easy to fit a new ballcock as has been said!Posted 6 years ago
