It is unlikely you would have to pay for the engineers time. The shower is making a noise which is not or at least should not be right. I can't see how an engineer could justify making a charge if there is a definite symptom. If it has not been installed correctly then that is a different matter, but then that's not your problem anyway. jemball wrote:I certainly wouldn't risk having to pay for an engineer's time, especially as they are all probably primed to deny any faults? I fit showers all the time and occasionally have to arrange engineer visits. I have never seen a chargeable visit. In fact, I would say they are always fair. In my experience, it is certainly not the case that they are "primed" in any way. Replaced unit damaged by hard water. The shower is like new now. Excellent service by Shower Spares.
