Hi
I'm sorry if this is going to be long-winded, but I had a water pump that served the hot and cold water to the whole of my house, but after just two and a half years it started to leak (hot side). I discovered that it was possible to fit a seal kit and the pump engineer came on Saturday morning to do it.
When he took it apart it was absolutely full of limescale, so full in fact that he said he'd never seen anything like it before. The limescale could not be rubbed if, nor scraped off, he said it was almost like some process had coated it. He couldn't repair it as it was so bad that the pump shaft broke during his endeavours. The impeller and everthing was caked in this stuff. I do live in a hard water area, but in the four years I have lived here I have only discaled the kettle once so it does seem pretty odd.
I had already arranged for him to change some valves and the flange as he thought the reason it was leaking was because air was being drawn into the pump causing it to leak. This work has now been completed and I have a new pump.
My worry is why the huge amount of limescale. He checked the temperature of my water, that is just under 60 degrees and he also asked me if I have had a dripping tap as he thinks the limescale may be due to water running through the pump at all times. I have not had a dripping tap. Then he suggested that maybe I have a leak in the hot water system, most likely under the floorboards as there is no sign of anything anywhere else.
This is my dilema. Based on this experience of excessive limescale in the pump, is this enough to tear the house apart looking under the suspended timber floor for a leak. Obviously this is a huge upheaval. I have a cloakroom with laminate flooring, a kitchen with Karndean flooring and a utility area tiled out? Hubby is of the opinion that we should just leave things but I'm going around with my head to the floor listening for anything dripping, but of course I can hear anything! Would the air being drawn through the pump cause the limescale?
Any thoughts on what might have lead us here would be very gratefully received.
