I have an ancient Baxi back boiler that serves for hot water and unused central heating radiators.
In the loft I have two tanks that feed each other somehow, the smaller one has been dripping for a week.
I thought it was lime scale, but after climbing into the loft and 'working' both ball valves and giving them both some adjustment, the dripping hasn't stopped.

Any suggestions how to cure it ?

I brought in a plumber who told me it was not the ball valve, but the cylinder.

Before he comes to change it and I hand over £525 I need to ask if the drip is me for believing him, or could an old cylinder be the cause of the drip ?

There’s a chance that the coil in the cylinder has pin holes therefore letting the hot water store fill the heating header tank.

The cold water storage tank in your loft would have to be higher than the heating expansion tank for this to happen

I must add that £525 is a good price for a cylinder swap.

I would be more than that and also plus vat.

And the plumber isn't Polish either.
