I'm getting quite a significant leak coming through the overflow in the coldwater tank - started about 2-3 weeks back. The tank is in the loft, hot water cylinder (about 18 months old) on the 1st floor & boiler (about 20 years old) on the ground floor. I swapped the ballcock out (about the limit of my expertise), which made no difference. Had a plumber around who did exactly the same thing & again no difference. I had a closer look & realised that water is coming back up from the pipe that feeds the hot water tank & the cold water tank actually contains warm (ish) water. The plumber is now suggesting that I replace the boiler (it's old but still kicks out a lot of heat), although he doesn't seem convinced that it will cure the problem - any suggestions please ? One thing I did spot whilst I was rooting about is that there's no thermostat on the hot water tank, which doesn't feel right to me ? The hot water tank was installed by the same plumber. I don't mind getting the professionals in to do the job, but would like a second (or third) opinion, as I've lost confidence in the professionals I've used to date. Thanks for your time
