I replaced an older CT50 with a new one (same Model).
The new one has slightly different electronics, but otherwise looks pretty similar.
The old one worked fine before London limescale ended it's life.
The new one works pumps water fine, but when cold water is run from the sink or bathtub, the pump kick starts itself.
Water inlets are at the bottom, outlets at the top, and all items (shower, sink, bathtub) are not changed, only the pump.
Hot water can also trigger the pump, but does it less often.
Help!!
Thanks!!
