Hi guys i have a condenser boiler ,the prob i have is the hot tap on the bath will splutter then stop or run slow or even just trickle ,but sometimes its ok ,the basin and down stairs taps ok,i called B/gas the engineer said it was not the boiler ,and have to call a plumber,i had a new bath fitted last year wondering if it could be a faulty tap, bath has two taps not mixers, thanks
