Part 2 ballcock valves

Cinquestelle

My toilet used to be a place where I could sit and think, but not anymore. I’ve replaced an old Part 1 ballcock valve with a Part 2, and now instead of peace and quiet all I hear is an irritating slow drip drip echoing from the cistern behind me.

The tank fills with water quickly with a rush as you would expect. Then a trickle. Then the drips, the interval in-between gradually widening. At the 1½ hour point there is a drip every 30 seconds. If I pull up the ballcock arm it does shut off the water almost instantly. But left to its own devices it seems that it takes hours.

Is this typical of all Part 2 types or have I bought a dud?

Very typical.

Should have gone to specsavers and bought one of these

What you are experiencing is standard operating procedure for old type ball cocks.
Change the valve for a Torbeck valve. These run full bore and then cut-off instantly and completely. Not expensive.

In one of my toilets, there's a polythene tube running down from the water inlet, so that there's no dripping noises. Don't know if this sort of thing is still available, or even if it was just a bodge that the previous owners put it.

Regrettably, not even Specsavers would change the fact that the my cistern is a side-entry.

I think you will now find these are not allowed anymore for some unknown reason. I know when I worked in the builders merchants trade in the 1950/60's we sold them buy the hundreds to the plumbers.These days the outlet on the ball valve are not threaded to stop people trying to do a fitting like that {when I sold them the ball valve outlet was threaded}
I know that if you could still get them today I would be the first to get one as it would mean a totally silent cistern fill every time

Sounds good. I will look into this. Thank you.

I believe that the reason is to prevent the possibility of tank water being sucked back into the household water supply where the cistern is connected to a mains. Certainly my old Part 1 had a silencer, but the new one didn't. If I don't go for the Torbeck style I may try to place something under the drip to help allow it to run off quietly.

Nothing more complicated than a piece of nylon string from the water outlet to the cistern water. The "drip" should run down the string.

adjust it (water level, ball level, or stopcock/inline flow valve), or rotate the outlet so it drips onto the valve arm instead of the reservoir.. or check the washer.

a new valve and ballcock shouldn't drip for 90 seconds or 90 minutes.

In which case you definitely need to go to specsavers - because the same 'shop' sells this too

And on a serious note - I have found that because these 'fill' the cistern from the bottom they are very quiet and cannot drip

The brass shank makes for a more reliable connection too.
