Hi
First time poster so apologies in advance!
Just bought a place with a private water supply (well). The water tests are dodgy so I am upgrading and putting in filters. I am concerned about some of the plumbing and would be grateful for any advice particularly as we have a young child and don't want to take any risks. The system is fairly conventional, water tank in a bedroom airing cupboard (loft too small) which is fed from the well pump, then all the cold water supplies (including kitchen) are taken from the tank under gravity. The tank also supplies the hot water cylinder which is vented and indirectly heated by a coil connected to the oil fired central heating. The CH header tank is above in the loft space. Couple of things worry me:
a) The water tank had no lid and the contents looked like a pond; brown sediment, gloop hanging off the ballcock valve, green rust (verdigris?) and most of all cream coloured scale/sediment up to the water line, on the underside of the ballcock and in one of the cold outlet pipes.
b) The overflow from the CH header tank fed straight back down into the cold water tank. A lable says that Fernox has been added.
So my questions are:
1) Will the overflow have introduced Fernox into the cold water supply? How dangerous is this and can I be confident that I can flush it out of the water pipes and hot water cylinder with something? Don't want baby drinking Fernox.
2) Anyone know what the cream coloured scaling is?
3) I have removed the cold tank and will replace this. I intend flushing with something like chlorine dioxide to sterilise the entire system, but is there something else I can use to scour the system out and remove sediment, scale, fernox etc.
4) Finally the overflow from the CH header tank. Can i connect this to the cold water tank overflow but obviously downline from the tank?
Sorry for so many questions. Would appreciate any advice.
Cheers
Neil
