deNs Yep I think it's a Laing DDC…seems like they're a bit hard to find these days…a lot of the PC pumps now seem to have built in reservoirs etc. I didn't recall them costing much when I bought the pair. Probably would be wise to try and source another one just in case I need it in future. I think the spare that I put in recently might have been the one we put in originally and had some issues with. In the end, I think that probably was a poor crimp/connection on one of the wires or a poor earth as the wires on the pump are very fine.
