water flows when pushing a pipe

Markus9

Hi,

I'm a total noob in plumbing, apologies for the poor way I'll explain this!

I was in the attic to insulate the pipes running from the water tank to the bathroom and I could hear water dripping in the tank but all the taps were closed.

I've noticed that slightly moving one of the pipes away from the tank the noise stops but if I push that pipe towards the tank it increases, it's actually a proper water flow.

Why is that? What can I do to stop the dripping?

Thanks in advance for your help, I hope I was able to explain the issue.

When the filling valve is almost closed they can drip for a while before completely closing. Excessive dripping, all night for example, would indicate the valve needs to be replaced. By pushing / pulling on the feed pipe you are probably changing the angle of the valve in relation to the water level hence the opening and closing.

ok thanks for the explanation, for now I've put a small piece of insulation between the tank and the pipe and I can't hear the dripping anymore, so maybe it's in the right position. Because otherwise it was always dripping.

Is that ok or should I call a plumber to change the valve?

Thanks

If its opening and closing when its meant to, then it all sounds fine, no need to do anything else.
